[c-nsp] SFP-GE-S/L vs GLC-SX/LX

[Tim Durack]

On a SIP-400 / 2-Port GigE SPA combo, do I really have to use Cisco
SFP-GE-S/L optics?

I was kind of hoping to get by with using the same GLC-SX/LX optics as
the 6748 linecards support.

"service unsupported-transciever
no errdisable detect cause gbic-invalid"

Not supported on the SIP-400 perhaps?

What do the SFP-GE optics give me that the GLCs don't? I notice
mention of DOM, but not sure if that is even supported on the 6748
card. I'd like to run a single kind of optic if possible, but that's
looking less likely now. (I'd also like to use Finisar/MRV rather than
Cisco, for obvious reasons.)

Thanks for any input,

Tim:>
