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....
The answer:
It shows 3750X
stack can accept the following 10 Gbps optical transceivers:
SFP-10G-SR
SFP-10G-LRM
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
Catalyst 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).
