6500 x2-10GB-LR or x2-10gb-lx4 compatibilty with sfp-10g-sr....

Hi Guys,,

Can any one advice if x2-10gb-Lr is compatible with sfp-10gb-sr ...i know its not compatible with x2-10gb-lx4 but 3750 stack i have has a c3kx-nm-10g module for sfp and core 6500 hunderd has lx4 .....link is not coming up .....i also have cvr-x2-sfp converter but i donty think 6500 support em...any clever way around this situation....is there a module for lx4 that can be fited in 3750 or module for sfp 10g to be fitted in 6500....need help . thanks

regards

Farooq,

You would get better exposure for a question like this one on the Optical Networking Forum but here is your answer:

Please refer to 10-Gigabit Ethernet Transceiver Modules Compatibility Matrix

It shows 3750X stack can accept the following 10 Gbps optical transceivers:

SFP-10G-SR

SFP-10G-LRM

SFP-10G-LR

SFP-10G-ER

...and 6500 can accept many types depending on the card model.

The basic parameters you need to be concerned with are single mode vs. multimode, wavelength and optical power levels (in the case of singlemode applications).

Starting from the 3750 end you mentioned using 10GBASE-SR there. That is an SFP+ transceiver module for MMF, 850-nm wavelength, LC duplex connector.


So your 6500 end needs to be multimode fiber (MMF) type. You Xenpak LX4 meets the mode type criterion but not the wavelength criterion. It is a transceiver module for MMF, 1310-nm wavelength, SC duplex connector.

One end being 850-nm and the other being 1310-nm means they will not establish link and are incompatible.

The compatible transceiver at the 6500 end would be XENPAK-10GB-SR= (10GBASE-SR XENPAK transceiver module for MMF, 850-nm wavelength, SC duplex connector).
