Which SFP Module for WS-C3750G-12S switch to enable port for 100MB copper

Unanswered Question
Oct 21st, 2009

Which SFP module should I use for my WS-C3750G-12S switch so I can connect a LES100 (100MB)link to the switch. The LES100 link is presented on an RJ45 cable. The WS-C3750G-12S switch has no RJ45 ports.

The LES100 link is over 500 meters.

Many Thanks

I have this problem too.

That's what I thought but have just been informed by BT that it will run at 100MB.
