X2-10GB-LRM to SFP-10G-SR= Compatibility

Hi,
Can you help me in this ?
I have two 10Gig modules.
On 6500, i have X2-10GB-LRM and on 3750-x i have SFP-10G-SR= .
you can use it with fiber cable and patch cord to connect the two devices?
thanks

Hello,
SFP-10G-SR is a MMF and it uses a LC duplex connector.
X2-10GB-LRM is also a MMF and it uses LC duplex connector.
so they are compatible.

Fiber Patch cord bewteen X2-10GB-SR and SFP-10G-SR

I would like to know which patch cord should I be using between X2-10GB-SR and SFP-10G-SR. The mention of part no would be very helpful.
Thank You

Thanks Sulaiman for the correction. I should not have relied purely on memory as it has potential of failing :-).

Fiber Cable to interface between Xenpax-10gb-lr++ and sfp-10g-sr=

I'm extending our network via 10gb fiber to the another building. The 6509E has the XENPAK-10GGB-LR+= which is rated for SMF, 1310-nm wavelength, with SC duplex connector. The other end 4500X has an SFP-10G-SR= that is rated for MMF, 850-nm wavelength with LC duplex connector. Between both sites there will be a SMF cable via G.652 (1310-1550nm) which will be terminated at both end via ST connectors in there respective Fiber distribution boxes. Question, since the SFP-10G-SR= that is ONLY rated for MMF 850-nm wavelength, will this pose any issue? Can you give suggestions on what type patch cables to use? Thanks

"Between both sites there will be a SMF cable via G.652 (1310-1550nm) which will be terminated at both end via ST connectors in there respective Fiber distribution boxes"
Since you have G 652 SMF you can't use SFP-10G-SR MMF as other's wrote earlier. You need to buy new 1310 SFP i.e you neeed
Cisco SFP-10G-LR
The Cisco 10GBASE-LR Module supports a link length of 10 kilometers on standard single-mode fiber (SMF, G.652).
For 4500X you need you need LC-ST patch cable.

SFP-10G-LRM and Intel E10GSFPLR Compatibility

Hello,
I wonder if someone can help me with a seemingly simple but elusive question. I'm looking to make a purchase of several SFP-10G-LRM modules to support 10Gb communications over our OS2 fibre infrastructure. All runs are less than 300m so this is cost effective compared to using SFP-10G-LR.
On the other end of the fibre will be some servers using Intel E10GSFPLR (10Gb 1310nm) optics.
My question is this - are these optics compatible for the situation I've described? I've done some searching and can't find any definite information either way, despite these being popular choices (I guess).
Any help is appreciated.
Thanks,
Andrew

Unfortunately, optical transceiver modules do not auto negotiate for speed. Therefore, you cannot connect a 10Gbps interface to a 1Gbps interface. You need to upgrade both ends before the circuit can be completed.
If you need equipment to support the intermediate step in the upgrade cycle, you might look at purchasing Cisco Refurbished Products.

SFP-10G-LR and SFP-10G-LRM Compatibility

Hello,
Has anyone had success/experience running across OS2 SM with a SFP-10G-LR at one end and a SFP-10G-LRM at the other, where the total link length is <300m?
Thanks,
Andrew

Dear Dima L,
I will check this tomorrow... but expect the same error.

Interoperable ASR1000 XFP for SFP-10G-LRM ?

I have a 4507R+E switch with SFP-10G-LRM (in WS-X45-SUP7-E) that I want to connect to an ASR1006 with SPA-1X10GE-L-V2.
What XFP can I use to implement my required 10G uplink?
I'm looking at XFP-10GLR-OC192SR [with signle mode fiber], but I don't know if that is interoperable with SFP-10G-LRM.
I suspect the XFP-10GLR-OC192SR would work with a SFP-10G-LR but I have already invested in the SFP-10G-LRM.
As an aside, will my SFP-10G-LRM interoperate with a SFP-10G-LR if I connect using single mode fiber?

AFAIK they should interoperate over SM fiber distances in the range you noted. Protocol-wise the encoding is definitely interoperable. The concern is generally receiving light at optical power levels the receiver can translate into electrical signals faithfully (and of course transmitting at levels adequate for the distant end to do the same).

SFP-10G-LRM modules with MM fiber OM3

Hi All,
Can the Cisco SFP-10G-LRM transceiver be used with Multimode OM3 fiber? if so, what would be the cable distance?
thanks

The SFP+ data sheet does indicate support for OM3 & OM4 fibers (no launch cable required). 220 meters looks to be the link length spec.

SFP-10G-LRM interoperability with SFP-10G-LR

I previously included this in a more complicated query (“Interoperable ASR1000 XFP for SFP-10G-LRM ?”) that didn’t generate any responses, so here is the revised question:
Will a SFP-10G-LRM interoperate with a SFP-10G-LR if I connect using single mode fiber?
(Fiber length would not exceed 100 meters.)
Power and wavelength specifications for the two SFP+ modules seem to indicate that they would work together:
http://www.cisco.com/en/US/prod/collateral/modules/ps5455/data_sheet_c78-455693.html
I’m just concerned that there could be some protocol differences. Otherwise I’m not sure why there would be two different standards, i.e –LR and –LRM.
I checked the "definitive source for everything" and that didn’t clarify LR/LRM interoperability either:

Thanks.

Sfp-10g-lrm dropping link

I have 2 switches WS-c2960s-24PD-L one of the SFP ports on both are connected to other switches running the 10g-LRM SFP modules. The two 2960 in question are connected by 1000BaseSX SFP modules. When i try to replace the !gigs with the 10gigs (on both ends) the config is the same on both ends. when i swap out the sfp the link will come up for a few mins then drop. i can do a shut/ noshut on the interface and it will comeback then go down again. Can any one give me some idias to try This link is working fine with the 1Gig SFP.

What is the distance of the fibre? If the original was running on GLC-SX-MM then you should've replaced them with SFP-10G-SR and not LRM.

Cisco Nexus 5548UP support SFP-10G-LRM ?

Hi all, I have a question about Cisco Nexus 5548UP. Is Cisco Nexus 5548UP support SFP-10G-LRM ? Because in CCW, i can't configure the SFP-10G-LRM. There is only SFP-10G-LR, SR, and the others, but there's no LRM. Pelase help me to answer this question. Thanks a lot

The LRM is s special case transceiver which supports 10 Gbps over older FDDI grade multimode fiber when used with a mode conditioning patch cord. It is not supported on the Nexus 5548UP.
The SFP-10G-LR is used with single mode fiber for spans up to 10 km in length. It is supported on the 5548UP (and most every platform of Cisco's that takes SFPs).
Please see the product data sheet here.

X2-10G-LX4 and SFP-10G-SR

Hi
Issue 1
I have a 6506-E with WS-X6708-10Gig Modules and i have installed X2-10G-LX4 transceiver on them, on the other side i have a UCS 6120 and installed a SFP-10G-SR.
The link between the 2 does not come up, what could be the reason for that? The distance between the 2 is 10 meters and i have already tried changing the cables.
Issue 2
If i connect the WS-X6708-10Gid module with X2-10GB-LR module and connect it to X2-10GB-LR on another 6506-E, the link comes up. that means there is no problem with the Module or the ios on the switch.
but if connect X2-10GB-LX4 on 6506-E and X2-10GB-LX4 on the other side, the link does not come up. Any clue what could be the reason ? I have already tried changing the transceiver.
Can someone please help ?

You have got answer for first issue that LX4 cannot work with SR. By the way what kind of fiber you have Single Mode/Multimode?
second issue,
If your X2-10GB-LRmodule have worked then i can assume that you have single mode fiber for testing as LR is only for Single mode fiber .
LX4 is only made for Multimode fiber and it is not going to work on single mode fiber no matter what you try (as you are saying link is not comming up).
Cisco X2-10GB-LRM is the only module which can work for Single mode and Multimode (ofcourse you need Mode conditioning patchchord )

Cisco 4900M integrated X2 ports, CVR-X2-SFP10G and SFP-10G-SR

Hi,
We are going to order two(2) cisco 4900M switches for core and twelve (12) 2960S switches for access (4 stacks with 3 switches each), connected to the core with 10G MM optical paths (up to 300M each). In addition I have one gigabit half-card but it is not related to my questions here. Please see my attached diagram.
So my questions are:
1. Point 1.Can we use integrated eight X2 ports of every of the both 4900M switches as plugging into four of them four convertors CVR-X2-SFP10G and to plug on every of the convertors sfp tranceivers SFP-10G-SR - as it is described on the diagram, or I need for something more in addition to described? I found only some minimum soft releases to use as requirement to use these convertors and sfp tranceivers, but is there something additional I need?
Note:I'm asking that because Dynamic Conf Tool doesn't give me to do such configuration, actually these convertors and SFPs are missing there at all, but it sometimes happens with some products... In documentation it is described this should work (if I didn't pass something which is my main consern and why I'm asking here).
2.Point 3.If this shouldn't work, the other alternative (not described in my diagram) is to use X2-10GB-SR modules without any SFPs - just ot use SC connectors for the optical cables instead of LC. So my question in that case is will 10G links work between X2-10GB-SR at one side and SFP-10G-SR at the other side where I have 2960S switches and this is the only option? Is is expected to have some problems in that scenario?
Note:Actually if Point 1 is workable I prefer to use it instead of Point 2 because of minor price optimization when using SFPs with convertors in comparisson to X2-10GB-SR.
3. If the both variants are possible, which one is preffered and why, what advantages does it have (for example low latency of something else)?
Thank You in Advance
Asen

Just for your information, a fiber link does not care if one end of the fiber has an GBIC (SC-type connector) and the other end has a SFP (LC-type of connector); or any other transceiver footprint (X2, CFP, etc.).. The thing that is important is that each module is the same specification, and matches the fiber type and link length of the network (10GBASE-SX in this example).
Good luck.

Cisco ASR1001-X SFP-10G-SR: unable to bring 10G port up

Dear colleagues,
I have connected a Cisco ASR1001-X 10G port to a 10G port on the Cisco 7606-S. The SFP on my ASR1001-X is SFP-10G-SR and the SFP on the 7606-S is XENPAK-10GB-LX4. I am using an MMF fibre patching. I am unable to bring the port up. I have a temp license for the ASR 10G port. Is that sufficient to bring the port up?
I have tried connecting the SFP-10G-SR to a XFP-10G-MM-SR on another ASR but this did not work either. I am able to connect the XFP-10G-MM-SR to one another and also the SFP-10G-SR to one another. So there appears to be an issue when I mix the SFPs.
Can any one help please?

The SFP on my ASR1001-X is SFP-10G-SR and the SFP on the 7606-S is XENPAK-10GB-LX4. I am using an MMF fibre patching.
The two fibre optic modules are on different wavelengths so the link won't come up.

Can the SFP-10G-SR down-support connect to SFP 1000BASE-SX ?

Hi everybody:
today i use the SFP+ "SFP-10G-SR" in Cisco Catalyst 2960S-48TD-L connect to 1000BASE-SX SFP in 6509's module WS-X6724-SFP.
the port setting is trunk,but they don't work, even the led don't flush. then i also use the 1000BASE-SX SFP to replace SFP+ SFP-10G-SR in
2960S-48TD-L, then they cany working.
i look up the cisco data sheet , there are no data sheet to satament the 10G sfp+ can't down support 1G sfp. so i want to confirm the problem.
otherwise, the 10 SFP+ only can use for 10G SFP+ ; can't down suport 1G SFP.
this means: if you want to use the 10G SFP+ the other old device also need to replace.
thanks~for your help!!

Hi Marvin,
I found this conversation today, as I am looking for answer on question similar to question that Jerry asked, while opening this discussion.
So, my problem is the following. At some location, I need two 10GB and one 1GB connection over optical cables. To minimize costs, I tried with WS-C2960X-48FPD-L, but as it contain only two SFP+ ports, I tried with two WS-C2960X-24PD-L that will be connected with stack modules.
So, having two WS-C2960X-24PD-L, I can have 2 x 2 1GB SFP+ ports. There are two opened questions:
1. Can I put 1GB SFP transceiver module in SFP+ port (as I must have one 1GB connection to remote site)?
2. Can I use stack of two mentioned 2960 24-port switches, in a way that I use one of them for two 10GB connections (using SFP+ ports for 10GB connection), and second member of the stack in a way that one (of two available) SFP+ port is used for 1GB SFP connection (using SFP+ port as mentioned in question 1)?
I am not sure if your previous statement covers my questions, as it is not clear if 1GB SFP transceiver can be inserted in SFP+ port on WS-C2960X-24PD-L (or any other switch that has SFP+ port).
