[c-nsp] Sorta OT: MM GBICs

[Church, Chuck]

I've heard both rumors.  I found this:
http://www.t11.org/ftp/t11/docs/GBICR4-5.pdf

It seems to be a laser.  But then again it's not Cisco.  Whether or not
it's possible to get 850 nm light at the  correct power with either
laser or LED is something I'm not sure of.  So maybe both are
possible...

woops I stand corrected by a transmission guy - ITS AN LED and that's
final.
