[c-nsp] SFPs (Third party) - ordered "standard" LH, but got "ZX"

[CiscoNSP List]

Ah - The plot thickens - On the connecting port, same SFP batch, but in an ME3600(i.e. ASR->ME), it is reporting as LH...so perhaps it's a cosmetic bug in IOS (These ones are still running 15.3(3)S3...havent upgraded them yet as they have been sitting in the lab waiting for a DC to be ready.


Anyway - sh int trancei on the ME, I see:


Opt TX: -7.1
Opt RX -5.9


Is that a "normal" level for LH? (Sorry, dont have access to any other ASR's or ME's atm to compare.


Cheers.

that looks like 1310nm to me.  What does the other side say?

ZX would normally inject at +1dBm to -1dBm.
