Fiber Network

I am looking for a product that will suit my needs.
I have two Fiber cables consisting of 24 cores each, 1 cable will be used on 12 different networks, the other cable is a redundant path for those 12 networks. I need a switch capable of keeping these networks isolated from each other but also capable of detecting a fault/issue and automatically switching to it's redundant path. If it has had to switch to the redundant path the switch will need to annunciate that there was an issue with the network that faulted.
Is it more logical to get 24 seperate switches with 4 ports that support IGNP snooping? Does this product exist?

You want to PHYSICALLY separate? If virtual separation is acceptable then you can use VRF.

  • How to use TC as backup in fiber network?

    I've just got a new fiber network installed at home and I'll use the wireless functionality. And to that I would like to connect my TC. I do not want the TC as a base station only for backup and as a hub for my printer. How do I do?

    Just bridge the TC and plug it into your main router.
    You can also turn off the wireless although there is nothing wrong with using the wireless as it is probably faster for backups to connect directly to the TC.

  • 4GBps Fiber Network between 2 Mac Pros

    Just had a thought that may be silly, but since I don't know any better I'm asking anyway.
    I'm thinking of getting some sort of RAID system that will deliver in the excess of 300MB/s. Since I also need a server to run Final Cut Server I was thinking of maybe combining the two... How would it work to use a PowerMac G5 with 6-8 RAID0 drives and connecting that directly to my Intel MacPro via 4GBs fiber? Would this work and would it deliver good, stable performance?

    You really need to clarify exactly what your suggesting... but from my assumption what you want is a top notch 1. RAID & 2. Server for Final Cut.
    Final Cut server is merely an upgraded sorting library. It more efficiently works at the levels of Journaling with OSX. Their is no need for FCS unless your in a large business working with the same data files on the same server. From what you are saying, apparently this machine your thinking up is going to be connected to just your machine. It will help in the workflow and organization of your files.
    As for RAID system. You mention connecting both Macs via fiber using 4Gb/s (not 4GB/s ) The 4Gb/s transceiver is only available on the intel model macs, not the G5. And your not able to connect the two machines directly as another not. Just as you need a crossover patch ethernet cable two network two home computers, you'd need to do the same thing here. You'd need a fiber switch to perform that. And as for the 6 - 8 RAID0 drives... I would suggest a simple external enclosure that's capable of fiber connections. I recall finding one before. Googling will prove helpful.
    So to directly answer your question... No. That would not be a stable system

  • Fiber being installed in my sub division Greenbrier SD, Apex will this be a pure Fiber network?

    Will the new service being installed in this SD be pure fiber or converted to copper over existing phone lines?  Old copper was the source of many issues when I ran ATT/DSL so if this installation is NOT pure fiber I will be uninterested in moving all my TV/Phone/IT needs back to ATT.

    Most likely it will be FTTN, or Fiber to the Node (aka VRAD) then copper for the distance between the VRAD and your home.  Millions of AT&T U-verse customers get good service over copper from their VRAD, but some people do have problems for a variety of reasons.
    FTTH (Fiber to the Home) installations are still relatively rare, except in the (isolated) areas where AT&T is rolling out Gigapower.  Gigapower is always pure fiber (aka FTTH).
     

  • How do I validate my fiber network?

    How do I validate my fiber port cabling when using the following Cisco transceivers?
    WS-C2950G-24-EI
    GLC-SX-MM
    GLC-LH-SM
    I want to develop a test to prove the “Lines” are good, poor or ugly, poor meaning the cabling has problems, too much attenuation because of bad splices, etc.
    I've found one document “OL-5067-05” that deals with Transmit Power, Receive Power and Power Budgeting for these GBIC and SFP modules. But how can I apply these values to my faculties, which is maintained by someone else? My faculties
    are world wide and I'm wondering about "Marginal" installations that might happen.

    An OTDR (Optical Time Domain Reflectometer) Will tell you how long the fiber is, within a certain resolution (frequently to the closest meter, some will do half meter) ... and is useful for finding the approximate location of a break, or the length of the run.
    For quality measurements, you'd use either a calibrated source and power meter and/or a Optical Spectrum Analyzer.
    When the fiber is/was installed (if it was installed by a professional), they do a power measurement for the span and record & report it to the consumer.
    With your own source & meter, you can compare the original reading to "what you got now" and determine if there is a significant degradation (dirt, crud, break, tight bend, etc).
    With a spectrum analyzer, you can see how much spectral dispersion your span is producing and the basic quality of your pulse train / signal.
    Sometimes several functions are integrated into a single device (JDSU does this, Fluke probably does too)
    Another useful tools is a Visual Fault Locator, which puts a very bright red light down the fiber. When the light hits a break, it scatters the light and you see a red blip from the fiber's sheath.

  • Problem connecting two storage networks

    Hello,
    I connect two datacenters with 10GB modules. I'm using single mode fiber, it has 10Km between datacenters. Now I need connect the storage network in both datacenters using the same fiber. The storage networks use FCoE.
    What solution can I use to connect the two storage networks. My budget is really limited.  
    Storage Network 1---------Network 1-------Fiber---------Network 2------Storage Network 2
    Thanks for the help.

    Brigid,
    There seems to be two aspects:
    One is to get the end points to coincide. You may tick View>Snap Guides, then click one path by the end Anchor Point and drag it to snap (Smart Guides say anchor when you are there).
    The other is to get rid of the gap in the stroke(s), You may join the paths into one, dragging across the coinciding Anchor Points with the Direct Selection Tool and Ctrl/Cmd+J, or you may keep the separate paths and change the Cap to Round in the Stroke palette/panel which will give you a rounded outer appearance); I presume the former is what you wish, in which case you may choose between Round and Miter Join.

  • Wi-fi network problem connecting & disconnecting

    my MacBook Pro wi-fi network is giving me problem after I changed to Fiber Network.
    It keeps connecting and disconnecting the Wifi network. I have no problem using Ethernet.
    Anyone know what happen?

    can you get anywhere on the internet with your laptop? What DNS is it using?
    yes, 8.8.8.8
    What servers do you have in your network? and what DNS are they using?
    i changed to DNS of mine ISP's，210.22.70.3, still can not go everywhere but google's service
    and if i set the DNS of ipad to a invalid server, i can not open google's page too

  • What will be tomorrows network infrastructure?

    Due to historical reasons, many different network infrastructures co-exist in today's networks, such as Ethernet, SONET, ATM, etc. However, if we are building a complete new infrastructure for a metro or large campus network, which technology would be the most appropriate? What is Cisco Expert’s opinion?

    I would answer this question differently if I were considering the use of the network to be a service providers network or an enterprise network in that I could achieve a different cost model based on single versus multiple customers on the same networks. Also, the end needs of each customer are different, and if they were completely defined could lead to a different cost model for the services rendered.
    Generally, a service providers network requires support for TDM and data protocols, requires stringent Service Level Agreements, and generally either owns their own or has a lower cost per mile for fiber than an enterprise. For this reason, a SONET/SDH based network with data capabilities provides the most cost effective way to transport the variety of circuits and streams from the end users location to the point-of-presence (POP) and a WDM system based network is used for the long haul and inter-POP traffic is used. Data can be Ethernet over SONET/SDH or WDM, or it can be done with RPR (802.17).
    The enterprise is usually seen as more fiber constrained, and therefore uses a metro WDM (Coarse or Dense) to transport SAN and Ethernet connections between buildings. The ability for the enterprise to convert most legacy traffic into Ethernet, and the ability to combine Ethernet ports into ever-larger trunk speeds, can also lead to very cost effective Ethernet over dark fiber networks up to the new 10 Gigabit per second standard. RPR systems can also be used to extend SONET/SDH recovery mechanisms to Layer 2 and 3 networks.
    With voice and video moving to native IP, and the ability to tunnel most other legacy traffic over IP, Metro Ethernet systems over dark fiber, or extended over WDM or SONET/SDH systems are beginning to be the most cost effective way for businesses to connect within the campus or metro today.
    The question we have to ask whenever we build a network is what will the next 10 years bring us. My vision is one of lots of devices with wireless mobility, the mixing of SIP and HTTP services to the mobile devices, and lots of high speed Global Area Networking overhead to figure out who and where you are. What is your vision of the traffic and protocols you will be required to support in ten years?

  • Google's Gigabyte fiber is now up and running

    1 GBPS for $70/mo.
    http://www.cnn.com/2012/11/14/tech/web/google-fiber-kansas-city/index.html?hpt=hp_bn5
    So why does Verizon say it's too expensive to continue building out FIOS?

    My thougth might be along the lines of what prisaz is mentioning, along with the fact that Verizon has already built out a significantly larger portion of the country with Fiber. Now the speed of course is nothing compared to what Google has going, but Verizon in theory could do it right now on GPON if they wanted to. With XGPON it will just be another walk in the park.
    Unlike what Google's doing, Verizon kicked resellers off of their Fiber network a few years ago. If you wanted FiOS cheaper for just Internet, DSLExtreme used to sell the classic FiOS tiers at the classic prices. You know, $30/m for 5Mbps/2Mbps or $60 for 50Mbps/20Mbps back when the service was cheaper and supported better. Kicking off resellers probably hurt them more than it did help as it definitely did turn down some folks from buying service due to cost.
    I might also put to the table the amount of income Google has in comparison to what Verizon's making. I'd have to look at financial statements but Google is pretty darn big. Don't forget too, they had to reach a ton of special agreements with Kansas City that allowed them to make it that cheap. Free pole space, no fees to the government, etc. Verizon couldn't get by that easy.

    The first to bring me 1Gbps Fiber for $30/m wins!

  • MM Fiber to MM Fiber

    Hello,
    I have 4 different fiber network feeds coming in from different buildings / closet into a room.. from that room a 24 strand fiber runs to the datacenter.
    All the fiber is MM 62.5.
    So lets say I want to run patch cables from each of the fiber patch panels to this 24 strand fiber and bypass using a switch in the closet all together.
    Is this possible?
    So for Building A it would look like this...
    Building A: 6 strands to fiber patch panel -> Miscellaneous Building Closet Fiber Jumper -> 6 strands to fiber patch panel in Datacenter

    Hi Jensen,
    don't use any switch in the middle. Just patch from one patch panel location building_A_incoming_fiber to the corresponding outgoing patch panel location Datacentre_fiber_out . Often these operations are referred as "loop" because you do not terminate the fiber on an active device but you loop it back to another fiber. As above mentioned, if your patch panel is passive (does not refresh the signal) you need to count the total distance and to compare to the type of MM fiber you are using .
    good Luck

  • Fiber date removed completley from BT Openreach af...

    Well for months I was with Digital Region on nice Fiber network getting 40Mps until it got shut down. BT then posted a date on their OPEN Reach whole sale site and BT own site with a date. It got moved a few times which is about expected but now there is no date what so ever and no mention of it coming on the Openreach wholesale site.
    http://www.dslchecker.bt.com/
    This is so annoying as the fiber cabinet I used on digitregion is right next to their old copper cabinet. So I am now stuck with less then 1Mbps.
    This all happened after the announcement that they will be taking over the digital region stuff. I just find it very bad form that every mention of it has now gone.
    I just find this all stupid as all the infrastucture is there but BT are messing around.

    Yeah, I see what you mean. Using the Full Address checker  http://dslchecker.bt.com/adsl/ADSLChecker.AddressOutput I get

  • Scripting over fiber

    I am writing a script the takes selected files and copies them to a destination. The Macs are connected over a Fiber network. The client told me you just need to use this code because there is NO IP. So will the line of code below get the data to its destination.

    You need to go out to the client site. Figure out how to do the task manually then automate it.
    Good for pr. Drum up more business while you are there. If you cannot to, ask the client to do the task & describe each step as they are doing the work.

  • Fiber & Cat5 LAN

    Hey,
    Im looking for some hardware for a network for 800+ clients... The building the network is designed for is very large and therefore no matter where there is a central server room, CAT 5 will not be able to reach... I could link the cat 5 between switches right back to the core but with the number of clients Im afraid this will produce a sizeable bottleneck...
    I was thinking of using fiber... However I have never had any experience with fiber networks...
    Basically what I am looking for is a fiber optic switch with 8-16 ports... I was looking a MM fiber with MT-RJ connectors... I was wondering if any one could recommend some optic switches that would work... I also need two 24port 10/100/1000 switches and 4 48port 10/100/1000 switches using cat 5 cable that are able to plug into the fiber switch...
    So I need....
    One 8-16 port fiber switch...
    Then I need a few gigabit switches that can be connected the fiber switch via an uplink port or GBIC card or what ever... I also then need to connect the fiber switch the server back bone...
    Im also looking to add wireless APs to the 10/100/1000 24/48 port switches... What is recommended for the number of clients... As not all clients will be using a wired terminal..?
    Any advice & recommended hardware would be greatly appreciated.
    Thanks,
    NW

    Hi,
    Yes that 24S should do the job, I guess is depends on the locations of the switches and the port densisty you need, plus how much money you want to spend and how much redundancy you want.
    Your alternative would be something like a 4500 filled with 100FX module and/or copper modules, plus redundant supervisor modules and power supplies.
    The 24FX is multimode MTRJ, plus SFP uplink ports
    the TS (G models) are 24/48 10/100/1000 copper with SPF uplink ports
    and there is a 12S with consists of 12 SFP ports.
    The SFPs are essentially small GBIC (1GB) modules that come in various types, shorthall or longhaul. The SFPs have LC connectors
    The 12S model could be filled with SX SFPs giving you 12 gigabit multimode connections
    You can also stack the 3730s to give you a combination of switchports on one logical switch.

  • How to connect airport extreme to google fiber?

    I have the Airport Extreme as the primary wifi station and add an Airport Extreme later. I recently connected to the Google Fiber network. I cannot figure out how to use this setup with Google Fiber . Any suggetions on how this can be done?

    As I said in the first reply .. the AE router was not designed for fibre.. and I have seen lots of people have issues for basic network problems to do with how ISP hand out IP and gateway addresses.
    Post the screenshots of what you have done..
    Did you get the AE plugged into fibre to work?
    Does Google use DHCP or PPPOE .. I am not in US so I am not familiar with the system used there.
    Post the main summary page. Then click the edit and post the Internet tab, wireless tab and network tab screenshots.
    Yosemite can be a particular hassle.. so please keep the setup in this way.
    Start with a full factory reset.
    Factory reset universal
    Power off the AE.. ie pull the power cord or power off at the wall.. wait 10sec.. hold in the reset button.. be gentle.. power on again still holding in reset.. and keep holding it in for another 10sec. You may need some help as it is hard to both hold in reset and apply power. It will show success by rapidly blinking the front led. Release the reset.. and wait a couple of min for the AE to reset and come back with factory settings. If the front LED doesn’t blink rapidly you missed it and simply try again. The reset is fairly fragile in these.. press it so you feel it just click and no more.. I have seen people bend the lever or even break it. I use a toothpick as tool.
    Then redo the setup from the computer with Yosemite. (same though with earlier OS if you are not using Yosemite.. this still helps)
    1. Use very short names.. NOT APPLE RECOMMENDED names. Use no spaces and pure alphanumerics, no special characters.
    eg AEgen5 and AEwifi for basestation and wireless respectively.
    Even better if the issue is more wireless use AE24ghz and AE5ghz with fixed channels as this also seems to help stop the nonsense.
    2. Use all passwords that also comply but can be a bit longer. ie 8-20 characters mixed case and numbers.. no non-alphanumerics.
    3. Ensure the AE always takes the same IP address.. this is not a problem when the AE is the main router.. by default it is 10.0.1.1
    4. Check your share name on the computer is not changing.. make sure it also complies with the above.. short no spaces and pure alphanumeric..
    5. Make sure IPv6 is set to link-local only in the computer. For example wireless open the network preferences, wireless and advanced / TCP/IP.. and fix the IPv6. to link-local only.

  • Optical Networking Layer 2

    I was having a discussion today about Global IP networks from AT&T, WorldCom, etc that are moving to the "IP+Optical" standard. From what I understand it fiber optic cable, MPLS and IP (OSPF, BGP, etc).
    My question is what is the Layer 2 technology? I may be thinking of this from a TDM world (I work on several enterprise networks), but if it's not Ethernet everywhere (they're getting there), what is the Layer 2 technology the breaks the packets into frames and frames the 1's and 0's from the fiber network ?
    I've read about RPR and DPT. Are these the Layer2 encapsulation used?
    Thanks.

    RPR and SRP (formerly called DPT) are Layer 2 MAC encapsulation protocols providing multiple access over Sonet. They virtually emulate a LAN environment.
    On point-to-point Sonet links the choice of Layer 2 encapsulation is HDLC, PPP, Frame Relay. ATM is a special case, not fitting in the OSI layered model. ATM can also be a transport over Sonet, which is always Layer 1.
