SFP and Mode Conditioning Patch Cable

Is it safe to assume any SFP designed for single mode fiber (i.e., MGBLH1) can work with multi-mode fiber if using a mode conditioning patch cable?

It should work. The "mode conditioner" adds a loss in your optical link, typically 2 db.
If you want be sure you must do a link budget.

X2-10GB-LX4 Mode Conditioning Patch or Not 62.5micron Fiber

I keep reading different things across the web. We are swapping out our SUP 720's with the newer VSS Sup 720's for the VSS technology. During the process we are going to start bringing 10Gb in. We have an existing FDDI (62.5 Micron MM) fiber plant. We purchased these with the X2-10GB-LX4 fiber modules designed to do 300m over 62.5 Micron fiber... Do we need a mode conditioning patch cord on each end? It would seem Cisco says yes or use the GBIC over single mode? I thought this was a multi-mode X2 module... I'm quite confused!!!

If you use the X2-10GB-LX4 transciever with 62.5 micron MMF, you need a Mode Conditioning Patchcord (MCP), part number CAB-GELX-625= or similar, on each end.
The -LX4 module it designed for MMF. In order to get a 10G signal through 300m of multimode fiber (which was originally designed for short, low bit rate paths) the LX4 module engineers used 4 coupled laser transmitters to send the information through the fiber. The Mode Conditioning Patchcords focus this laser light into the optimum section of the multimode fiber's core, so that it can reach the distant receiver and be successfully decoded.
This module, without the use of the MCPs, can be used on singlemode fiber (SMF). But, this module is more expensive that a standard SMF transceiver (LR or LRM) due to its use of 4 lasers and the WDM multiplexing integrated into the transceivers.
Does this help at all?

Mode conditioning cables for MMF.

Hi,
I have a building on campus, which is connected to my core switch over obsolete MMF (the link is approx 500m, but I can't indentify what type of fibre cable it is). Recently I upgraded core switch from 4006 to the new 4506E. In the 4006 I used GBIC SX modules on both ends, but after the upgrade I can't use those anymore.It seems that I need SFP LX/LH (cisco part GLC-LH-SM) on the core side and GBIC LX/LH (cisco part WS-G5486) in the access switch. Could you advice if I need mode conditioning cables to make it work? I figured that for my set up I'd need 1x LC to ST (core to patch panel) and 1 ST to SC (patch panel to switch). Help please...
thanks,
forman

I have question regarding your network.
1) Are you planning on using the installed “obsolete MMF” that you were using with the 4006 switch or is there some other fiber you will be using (what type)?
If you are using the original “obsolete” MMF, then you should be able to install a GLC-SX-MM SFP in the 4506E and connect to the original SX GBIC in the access switch.
If you will be using the original "obsolete" MMF with the 1000Base-LX/LH transceivers, then you will need a mode conditioning patch cord (MCPC) at each end. These cables are available from many suppliers. Below is a link to a vendor that sells MCPCs that have the ST connectors you need

Long Haul Mode-Conditioning MultiMode GBICs?

We have a fairly large legacy installation of Catalyst 3500s interconnected with 62.5 MMF. Most of the links more than 200m or so have these old Allied Telesyn EX-1002 "range extenders" which are alleged to be able to run up to 2km over MMF without the use of mode conditioning cables. And they do seem to be work as stated, we hve a couple runs just shy of 1km and they have been staying up.
The EX-1002s are starting to die off and I can't find a similar product. Actually, I can't find any technical information at all on the EX-1002, they say "1000-baseX" and seem to be longwave. Since they are said to operate at 2km, is mode conditioning built-in to the device?
The only other way around this is to use generic LX/LH GBICs and mode conditioning cables, which are very expensive. Or maybe just buy some EX-1002s on Ebay?
But, is there a GBIC available that is Catalyst 3500 compatible that can do long-haul multimode gigabit?
Thanks,

At the risk of bumping this topic too late, thanks for all the replies.
We have got everything working, but have not yet bought any mode conditioning cables. It seems to be cheaper for me to fiddle around with randomly swapping GBICs and patch cables, than systematically installing mode conditioning cables on all our links. :-(
A few observations:
- We have 1 or 2 links in the 300 - 400m range operating consistently on 62.5μ MMF with an LX GBIC on one end an an Allied EX-1002 "1000baseSX to 1000baseX" converter on the other (the "1000baseX" is long-wave. don't know if it's 1300 or 1310nm.)
- We have several links in the 300 - 500m range operating consistently on 62.5μ MMF with Allied "range extenders" at each end. We will replace these with LX GBICs and mode conditioning cables as the Allied devices die off.
- We have quite a few SX links operating in the 200 - 300m range, 1000baseSX to 1000baseSX. Occasionally we have had problems getting these to link up with a GBIC on one or both ends. As you would expect from the technical description of mode dispersion this is hit--and-missand randomly dependent on combinations of GBIC and patch cable. SFP-based SX links seem to link up more reliably at distances over 200m. (Perhaps because the tolerances are more precise and/or the SFPs are new and not old GBIC that have been sitting in some network admin's desk for 5 years.)

SFP/mode conditioning

I have some Catalyst 3560 switches that I need to connect over a long distance. The existing backbone is 62.5 850nm multimode and unfortunately I dont have the option of installing single mode fiber at this point. The distances range from 2000' to 6000'.
My question is - is this possible? and what parts would I need to make this work at 1GB/s?
I'm looking into the possibility of using a mode conditioning cable on both ends and a single mode SFP adapter for the switches. However, all I can find on the mode conditioning cables reference 1300nm and our existing fiber is 850nm. Is this a limitation of the existing fiber? Are there mode conditioning cables that support 850nm or does the SFP dictate what wavelength we are using?
Thanks in advance!

Take a look at the following Cisco document on operating 1GE over 62.5um MMF up to 2km....
Cisco Support for Gigabit Ethernet Deployments with Multimode Fiber Links up to 2 km
<http://www.cisco.com/en/US/prod/collateral/modules/ps5455/prod_bulletin0900aecd80425a37.html>
Depending upon your equipment, the GLC-LH-SM will probably be the SFP for your equipment. You can look at the following compatibility document...
Cisco Gigabit Ethernet Transceiver Modules Compatibility Matrix

X2-10GB-LRM and patch cables

Are mode conditioning cables required for switch to switch connection over multimode fiber (200Meters), if we are using fiber jumpers between device and fiber cable on both ends?
Thanks,

If the fiber between the two switches in not OM3 or OM4 rated multimode fiber (MMF), then you will need to use a Mode Conditioning Patchcords (MCP) at each end of the link; connecting switch #1 and switch #2 to your multimode fiber cable using the MCPs.
Switch #1 ---- MCP ---- Fiber Cable (MMF) ---- MCP ---- Switch #2
The following Cisco document outlines the use parameters of a Mode Conditioning Patchcords (MCP).
<http://www.cisco.com/en/US/prod/collateral/modules/ps5455/product_bulletin_c25-530836.html>

Can we have more than 2 "and/or" conditions in filters in advanced mode in power view?

Hi,
I need to check 3 conditions in filter in advanced mode in power view. Is it possible out-of-box. Can we customize the advanced mode filters or do we have some configurable options for same.
Thanks,
Bhawna.

Hi Bhawna,
I'm the Dev Owner for the filtering experience in Power View. Sorry it took so long for me to reply.
In the Power View Advanced Filter cards, you cannot currently add more than two conditions. What Rhys meant about having as many AND filter conditions as you like is that because all of the filter cards are AND-ed together, you can effectively have
more than two filter conditions by adding multiple 'LastModifiedDate' cards.
Unfortunately this won't help you if you're looking to OR more than two conditions.
Adding the ability to have more than two conditions in a single Advanced Filter card is something that is near and dear to my heart, but it does open questions of nesting and grouping which would need to be addressed first in order to be able to offer a
complete solution.
Hope this helps,
Jeremy

I should add that this has never been Jailbroken. I keep reading that a lot of times this is the case for a jail broken phone.
I have also gone through the not very helpfull steps on apples site to fix this.. It is not a security issue since i dont have an antivirus or any 3rd party software for my computer.

and i find many people have met the same thing. But they are spartan series FPGA and i try to low the Resistances of Mode pins,M0 M1 and M2, but the problem does not been solved.
I have read the status Registers and find there is an over-temperature state

I am anxious about this problem and have not solved it yet
What reasons may it be?
Hope for your answer, thank you

Hi~I want to know if you solve the configuration problem for virtex-6?
As I encounter the  same configuration problem, I want to consult  you with some question.
Can I have your email?

That is not at all surprising. I always assumed the problem is with reading the XADC (system monitor) block and not with the voltage or temperature.
my Reference board is ML605
That would have been nice to know at the beginning...
It seems that you have selected the correct mode, assuming your jumpers are set as required in the ML605 Hardware User's Guide. See table 1-27, table 1-33 and the note below it about switch S1.
I'm not that familiar with the details of this reference design, but it may be that the slave SelectMap circuitry requires a reset or power cycle to actually configure the FPGA. Have you tried power-cycling to see if the FPGA boots from the flash?
I'd also suggest that you select the V6 in the JTAG chain view, then go to the debug menu of Impact and select Read Device Status (this is from memory, but it's something like that). That will not only show the bits of the configuration status register, but also describe what each bit means. Among other things you can check the state of the FPGA's configuration logic and the Mode pins.

Ethernet Patch Cable from One iMac to AirPort Extreme Please help!

Hi, I have an iMac on one side of my home office, and a cable modem connected to my AirPort Extreme. I just bought a 25 ft. patch cable to run and connect to the router for faster speeds, but it is not working. I tried connecting it to the AirPort and the modem, and I did not get a light on the AirPort extreme or on the modem (I have disabled the wireless functionality on the gateway so it is just a modem now). I noticed that the cable has metal on the sides of the plug. Does that mean anything? How can I connect this and get it working properly?
Please help me!

your post is a little confusing
your imac is on one side of your home, and both your cable modem and extreme are on the other side of the house?
temporarily move the imac to the same side and try a different cable, seems like a cable issue

Minimum Fiber Patch Cable Length for MGBSX1

I want to "stack" a couple 300 series gigabit switches with fiber using a pair of MGBSX1 GBICs and a single LC to LC patch cable.
Is there a minimum supported patch cable length in this configuration?

Howard,
Thank you for posting. You should have no issues using a short fiber patch between the switches. Just make sure the fiber doesn't bend too sharply and get damaged.

Bug: Target Display Mode + optical audio cable = black screen

Using Target Display Mode on my iMac 27" (late-2012) with my MacBook Air (mid-2013) always resulted in a black screen on the iMac.
Hardware used:
MacBook Air mid-2013 (Mac OS X 10.8.4)
iMac 27" late-2012 (Mac OS X 10.8.4)
Thunderbolt cable between MBA and iMac
optical audio cable in iMac (digital audio out through optical mini jack plug)
Now, enter Target Display Mode on the iMac keyboard (Cmd+F2).
Result: black screen on the iMac (MBA is okay, optical audio is okay)
Workaround: unplug optical audio cable before entering Target Display Mode. Plug in the optical digital audio out cable after TDM is working and all is fine.
I sent a bug report through the feedback form. Just posting here to save others the few hours I had to spend finding the cause and workaround!
-- Richard

Thank you!! Saved me a trip to the Genius Bar.
Confirmed: Bug also exists in the new 2013 iMac under Mavericks. Unplugging the optical cable before entering Target Display Mode solved the problem.

The difference between SFP+ and X2

Dear Expert,
I need to know what is the difference between SFP+ and X2! and can I use SFP+ card and module instead of X2?
Thanks,
Mohammad Saeed

Hi,
They are both used for 10Gig interfaces. The difference is the connector type.
SFP+ is LC and X2 is SC.
You can not put an SFP+ into an X2 slot or X2 optic into a SFP+.
