Ciena 3930: must a 1GE SFP be Ciena-coded, or is matching the 1000BASE-LX spec enough
We pick up a 1GE carrier handoff on a Ciena 3930 and I am putting together a spares kit for it. The module quoted for that circuit is XCVR-A10Y31, a 1000BASE-LX/LC part: 1310 nm, 10 km single mode. Nothing exotic about it, and I have a drawer of generic optics with exactly that specification…
