What is the difference between Gbic-SX-LC and Gbic-LX-LC

[Sébastien Cramatte]

Hello,

We have got an HP procurve 2626 switch
We think to connect our internet provider fiber
to one of 2 Gbic port.

What is the difference between Gbic-SX-LC and Gbic-LX-LC ?

Thanks to light me
Regards

Hi

The GBIC-SX-LC is for Multi-Mode fiber cables for less than 550 meters.

The GBIC-LX-LC is for Single-Mode fiber cables up to 10km, and it also supports the Multi-mode.

The LC is the type of connector.

Price wise, the GBIC-LX is about 2.5 more expensive than the GBCI-SX.

Good Luck !!!

Thanks for your answer

As I told this we need this adaptor to connect our provider fiber so I supose that we will require Gbic-LX-LC ...

Might be it will be less expensive to find FDDI card ?

Seems that HP doen't sell anymore FDDI card :(

I wouldn't suppose. Different fibre optic Ethernet standards (SX, LX, LH, FX, FL, FP whatever) are not interoperable, whatever the length. Ask your ISP for a specification - although LX is most likely.

Gigabit Ethernet is far cheaper than FDDI ever was, as new. If you want to do things on the cheap an external transceiver might be cheaper than a Gbic. I don't understand why with a GigE link, a few hundred Euro on a transceiver would be a big deal, though.
