CISCO XENPAK-10GB-LW (WAN PHY)

hi,
do you know if installing the CISCO XENPAK-10GB-LW (WAN PHY) you need a SONET/SDH multiplexer or you can connect it directly to the SDH network?
any document explaining it?
thanks

The WAN PHY module will appear to your SDH network as a SONET tributary interface. Its signal will need to be carried intact as an OC-192 (approximately 10 Gbps) across the SDH network since it's not a bunch of STS payloads but rather a single 10 Gbps IP stream encapsulated in SONET framing. Other than that, it should be able to feed your SDH network's ADM just fine (given attention to your optical power levels, etc.).
Hope this helps, please rate helpful posts.

  • Allowable path loss between Cisco XENPAK-10GB-LR & HP BLc 10Gb

    Greetings All!
    How much attenuation loss should be allowed (upper & lower range) for 10Gb link between Cisco XENPAK-10GB-LR & HP BLc 10Gb?
    Thanks.
    Regards,

    Well the Cisco XENPAK 10GB-LR is spec'd for spans up to 10 km.
    Per its data sheet, the transmit power ranges from +0.5 dBm max down to -8.2 dBm min. Receive levels must be no greater than +0.5 dBm and no less than -14.4 dBm.
    The HP BLc 10GB (assuming it is the LR type transceiver) does not have any such detailed specification that I could find.
    I'd estimate worst case planing would would be the difference of the minimum Cisco Tx and the least allowable Rx power = 6 dB loss end to end. When in doubt, measure it!

  • Cisco XENPAK - HP2910 10GB interface

    Hi,
    We need to connect a Cisco XENPAK-10GB-LR module with a "HP ProCurve 2-Port 10-GbE SFP+ al Module (J9008A)" (a module inside a
    "HP Switch E2910-48G al(J9147A)")
    The HP switch module would have an "HP X132 10G SFP+ LC LR Transceiver (J9151A)".
    Where can I find some info if this kind of fibre connection is supposed to work ?
    The specifications for both the devices (XENPAK and the HP module/tranceiver) are same - 10GBASE-LR (single-mode fiber, 1310 nm).
    Regards,
    Florin

    Yes, the two transceivers will interoperate. 
    Make sure you order the correct singlemode fiber patch cords to interface to the LC/UPC connector type on the HP transceiver and the SC/UPC connector type on the XENPAK.

  • 10 Gigabit Ethernet Wan PHY vs LAN PHY

    hello,
    Is it possible to connect a 10 Gigabit Ethernet LAN PHY client interface (12xxx or 76xx) on a 10 Gigabit Ethernet WAN PHY port of provider équipment (Nortel 5200) ?
    what about the existence of 10 Gigabit Ethernet WAN PHY interface on 12xxx or 76xx plateform ?
    thank you in advance

    The Cisco ONS 15454 MSTP DWDM system offers a a 10Gbps transponder card supporting a 10GE LAN PHY client interface.
    http://cisco.com/en/US/products/hw/optical/ps2006/products_data_sheet0900aecd80101903.html
    I do not know if the Nortel 5200 DWDM system supports LAN PHY interfaces on their transponders.

  • XENPAK-10GB-LX4 and X2-10GB-SR

    Hi all, has anyone connected a FO using 10GB-SR and a XENPAK-10GB-LX4 gbic, could we have a problem if we do so for a cable distance of 80 to 120 meters.
    thks in advace.
    Mario

    X2-10GB-SR transceiver module for MMF, 850-nm wavelength, SC duplex connector while the 10GBASE-SR X2 transceiver module for MMF, 850-nm wavelength, SC duplex connector supports link lengths of 300m on standard Fiber Distributed Data Interface (FDDI) grade multimode fiber (MMF). To ensure that specifications are met, the transmitter output should be coupled through a mode conditioning patch cord.

  • 10GE-WAN-PHY to STM-64

    Hello,
    I would be grateful if anyone can help me with this problem.
    Is it possible to interconnect 10GE WAN-PHY port on router to STM-64 port on multiplexer?
    Is it generaly allowed to inerconnect SDH and SONET (or their frames and signals are not compatibile) i.e oc-192 and STM-64?
    I have DWDM with four STM-16/OTU-1 ports. I've planned to multiplex those 4 ports to one STM-64 and connect it to 10GE WAN-PHY router port.
    (router)10GE-WAN-PHY-----STM-64/OTU-2 (multiplexer) 4xSTM-16/OTU-1-----4xSTM16/OTU-1(dwdm).
    Is it feasible or I need some additional equipment?
    thanks in advance,
    A.

    1) When I connect 10GE WAN-PHY router port to STM-64 box, will router send STM-64 frames, or it has different frames then SDH?
    Is the 10GE WAN-PHY also compatibile with OC-192?
    Yes it sends STM-64 frames (but it doesnot have network management features which SONET/SDH STM64 interface have) See this link
    http://www.cisco.com/en/US/prod/collateral/modules/ps6267/product_data_sheet0900aecd80715dc5.html
    So  one to connect to a DWDM STM 64 /SONET- 192 trasponder which then makes  a proper SDH/SONET frame with all those management bytes.
    Same port can be either used for STM 64 or SONET 192. This STM64/SONET192 are still made from smaller SDH/SONET frames
    2) Do you know if Cisco has a box that can  interface two boxes  STM64----OC192 (or OC-3 --- STM-1)? Which type of  box is that generaly?
    Are you crossing  continent with your own infrastruture , service provider have  crossconnect that do that for them this conversionTellabs,Fujitsu etc  RAD for smaller line rates ? Cisco have boxes which either can be SDH or  SONET but see this link. Might be helpful.
    http://www.cisco.com/en/US/docs/optical/15000r5_0/planning/guide/r50sdhtr.pdf
    3) (router)10GE-WAN-PHY-----STM-64/OTU-2 (SDH/SONET box) 4xSTM-16/OTU-1-----4xSTM16/OTU-1(dwdm).
    I   wasn't clear enough in my previous post. I was thinking to put box   (multiplexer) between router and DWDM, which on one side toward router   will have STM-64 and toward DWDM will have four STM-16 ports.
    Is the scheme that I corrected now above in point 3) allowed?
    You  can have point to point link where STM 64 are demultiplexed to STM 16.  This is the way how 100G are trasnported over 10 x 10G. I dont see any  benefit on a extra box with point to point link.
    But If this 10GEWAN is your hub and have spokes which have router with STM 16 interface, then you can make 4 STM 16 pipes. All these you are trying to achieve are possible but you may need extra equipments to get the result.
    For one more opinion you can consult with Solution specialist from Cisco. Generally all marketing guys try to sell more than what you need.

  • XENPAK-10GB-LR+ not showing Proper product ID

    Hi Experts ,
    We have replaced exsisting "XENPAK-10GB-LR" with new "XENPAK-10GB-LR+" but when I see show inventory it shows a weird PID.

    Both Switches have same SUP "WS-SUP32-10GE-3B" only difference I see is IOS ,but I am not finding any documentation that says IOS is causing the switch to show incorrect Product ID .
    Services are working fine.

    Sounds like you are getting some data, jut not performance data(?) so I would not suspect the agent.
    Check your binaries on the agent - you should have 2 or 3 with root permissions and the sticky bit turned on.
    Make sure you have the new port numbers being used since the agent should now be connecting via the secure port (this looks to already be the case from your post)
    Hit the url from the web browser:
    https://<agent-host>:1830/emd/main
    Any firewalls between you and the oms?
    Does the agent know the oms dns/ip?

    Hello,
    We can think of 10GE LAN as a usual Ethernet we used to see.
    10GE WAN uses SONET/SDH  framing instead and hence can be directly connected to OC-192c/STM-64 interfaces at a carrier network. For diagnostics 10GE WAN PHY makes use of the SONET overhead bits to detect :
    - Loss of signal
    - Coding violations
    - Framing errors/ loss of frame
    - Errored seconds
    - Severely errored seconds
    - Loss of synchronization (not needed) •             Same Error/ performance monitoring
    - B1, B2, B3
    - J0, J1
    Same Defect/ Alarms
    - FEBE
    - RDI
    - AIS

  • Cisco RV042G DMZ for WAN 2?

    Hi, I run my business network on the 192.168.x.x range with a server set as 192.168.2.4 statically. The router is currently connecetd to two DCHP wan connections from my ISP, I'm on a residential consumer plan. It has defaulted to loadblanacing with the second WAN however I want to have the second wan's public IP be used by my server and only the server however I wish for the server to still be on the lan so I can use HYPER-V's brided network connection feature to run VMs on the lan, and I would like their wan connection to be from wan 1... as for the entire lan except the server at
    192.168.2.4 Is this possible, I can't seem to get the 1-to-1 NAT to do it?

    Dear Harley,
    Thank you for reaching Cisco Small Business Support Community.
    One to one NAT would be an option, same and most prefered in my opinion a Port Forwarding configuration since it just opens specific service(s) on the server from the outside.  The problem I see here is the dynamic WAN IP addresses you get from your ISP that if you can at least get the desired one assigned statically would solve the problem, otherwise I see no way to access the server form the internet since its IP address is unknown by the remote client or it just changes all the times.
    So you can configure the let's say Port Forwarding following the below document, p. 44, but how do you access to the server if we do not know the dynamic IP address your ISP is giving you at a given time.  I suggest you to contact your ISP and figure out if they can give you the WAN IP's so you can assign them statically to the WAN ports, or find out if by any chance they assign your WAN connection the same public IP's everyt time eventhough they are not typed in the router and figure out what they are so you can use them to access the server remotely using that IP address.

  • Cisco RV180 VLAN tagging WAN interface

    Is there by any chance in the future firmware update that this product (RV180) will be able to support VLAN tagging on WAN interface like the Cisco's RV315W router? ISP in Singapore (Singtel) and Malaysia(Unifi) (http://klseet.com/index.php/mikrotik/mikrotik-rb750-750g/setup-for-unifi) requires certain type of vlan tagging on the WAN interface for it to work. 
    Is there any workaround to this?

    I tried with only two vlans and set the DHCP active only for the office "vlan2". Computers receive the correct ip but some of them won't register on the network, i tried to set the ip manualy on the computers but that computer will still be isolated.
    Ex: computer A receives ip 192.168.10.25, Subnet 255.255.255.0, Gateway 192.168.10.1, for 2-3 minutes i can access the router on 192.168.10.1 and the internet, after a random time interval the gateway won't even respond to ping.It's not from firewall related issues as i set to accept all both incoming and outgoing. If i set a manual ip corresponding to vlan1 "default" everything works.It's like that computer is isolated so i believe it has to do with the asignment of Tagged, untagged and Excluded settings on the vlans.

  • Cisco X2-10GB-SR

    I have two Cisco 4506-e with the X2-10GB-SR modules that i would like to connect using fiber.  They are less then 10 ft apart.  Is there any "special" cable requirements other than both end have an SC to SC connector type?  Can the core size be 62.5 or does it have to be 50.0? 

    50 and 62.5 is supported.

    http://www.cisco.com/en/US/prod/collateral/modules/ps5455/ps6574/product_data_sheet0900aecd801f92aa.html
    If the entire length of the fibre optic cable is, for example, 50 microns, then it should be ok.  You'll see issues when you have 50 micron patch cords connected to building fibres of 62.5 (or vice versa).
    Other than that, it should be fine.

  • Connecting Cisco AIR-CAP2602E over WAN with WLC - Procedural Details

    Hi,
    I have a Wireless LAN Controller Installed in one of the subnets where some AIR-CAP2602E's are connected with the WLC. WLC acts as DHCP for the AIR-CAP2602E Devices.
    I have additional AIR-CAP2602E access-points at other location (Subnet) and Need to connect them with WLC. 
    Challange faced by me is creating DHCP on Cisco 2950 (L2) or 3750 (L3) with DHCP option 43. Can any one has detailed configuration of enabling DHCP for specific VLAN on Cisco L2 and L3 Devices. 

    If you have control of the DNS environment for these network segments, just make an entry for :
    cisco-lwapp-controller aliases cisco-capwap-controller (IP list) as the CAP will hunt for those two name sets.
    My WLC provides DHCP support only to the wlans supported by the AP but not the AP it self..
    hope this helps

  • Linksys/Cisco WRVS-4400N.v2 - WAN dual-pptp(l2tp) setup?

    Good day.
    I've recently received a WRVS-4400N v2 and I'm having the following problems:
    I don't see any way to set it up to work with my provider, as it works with so-called by Dlink "dual-access pptp (or l2tp). So, I'v got a static IP I receive, when I connect to L2TP server, but first I receive a dynamic, which let's me into their network. Did anyone try configuring wrvs4400n under such conditions?
    Second problem is that you cannot set it to access pptp/l2tp server by name, only by IP, which is not acceptable - access servers do change their ips from time to time.
    Are there any solutions\ideas? OpenWRT/DD-WRT don't support this model. Can I hope for a firmware upgrade, which will allow the aforementioned, or should I just get rid off this model?
    Thanks for your attention.

  • Cisco RV220W - Disconnect\Reconnect WAN

    Hi all,
    I have and D-Link modem which is bridged and a PPPoA\PPPoE profile set up on the RV220W for my ADSL2+ connection.
    I cannot for the life of me find anywhere in the routers config web pages to tell the modem to disconnect or reconnect the connetion to the ISP.
    The reason I want this is because I need to make sure the correct signaling is sent before the connection is stopped so that the exchange doesnt see this as a drop out and reduce our line speed to compensate.
    Any help would be appreciated.
    Thanks
    Michael.

    Hi Michael,
    Thank you for posting. You could uncheck "Internet Connection Requires a Log in:" and save the setting. This would change the router to DHCP instead of PPPoE and of course the connection to the modem would stop.

  • 6509 to ons 15454 showing not connect.

    Were running into a problem moving from an oc48 to oc192. In our web enviornment we have a Front-end switch and a Back-end switch in two data centers that are 10 miles apart. Were running a "gigaman" betweent the two. On both ends we have cs6509's and were patched into the Gbic interface on the sup2's. This fiber is ran to are lec's ons 15454 which I have no visibility into. We are unable to get a connection on the 6509's. Were doing basic layer 2 trunking between the switches. Sbc tested from the fiber on the switch to a loop on the other switch and was able to test clean. This worked on the oc-48 but are switches were not connected to a cisco ons. Any suggestions would be apperciated. You can also email me at [email protected] or AIM jjt8572.

    Have you checked that you have matched the physical media framing - e.g., LAN PHY needs to speak to LAN PHY (or WAN PHY to WAN PHY). Typically the ONS 15454 would be looking for a SONET frames (WAN PHY) while a Cisco 6509 would be sending 10 Gigabit Ethernet LAN frames (LAN PHY). That is, unless you specifically choose an interface for your 6509 such as the XENPAK-10GB-LW (10GBASE-LW XENPAK Module with WAN PHY for SMF). From that product's data sheet: "The Cisco 10GBASE-LW Module supports a link length of 10 kilometers on standard single-mode fiber (SMF) (G.652).
    WAN-PHY is intended to allow the transport of 10 Gigabit Ethernet over a traditional SONET/SDH infrastructure. The purpose of WAN-PHY is to render 10 Gigabit Ethernet compatible with SONET STS-192c format and data rate, as defined by ANSI, as well as the SDH VC-4-64c container specified by ITU."
    One can also use Cisco ONS transponder cards that will wrap LAN PHY framing in something like G.709 encapsulation to allow it to be transported through a DWDM network.

Maybe you are looking for
