[c-nsp] SFP compatibility

[Juergen Marenda]

Most SFP's (esp. Older one for "low" speed) are fixed frequency,
So they will not get in sync.

An "GIG" SFP syncs at approx. 1.25 GHz and will not operate at FastEthernet
Speed.

OK, there _are_ multi-frequency SFP's, 1G SAN+2GSAN +1GE for example,
but yoru device will not set the Clock to FastEthernet on the normal Gig-SFP
.
So the will not get in sync, and only see the light.

Hey Guys,

Probably a stupid question, but I can't find an obvious answer on Cisco.

Are the following SFP's able to be used to together:

One device is using at GLC-FE-100EX & the other end is using
a 1000BASE-LX/LH (Single Mode fibre).

I "think" these SFP's are compatible with each other.. But if someone can
confirm this it would be great.
