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

[CiscoNSP List]

...apologies....missed CC'ing the list:


Cheers Nic - This is for patching between kit in the same rack(sub 2meter patches)...if that makes any difference.


What levels should I be concerned about?


After a bit of digging, found this command for ASR1001:


show hw-module subslot 0/0 transceiver 0 status


Seeing:


 Tx power -6.0 dBm

RX optical power -6.3dBm


This port is connected to an ME3600, with a "ZX" SFP also.

they'll interoperate, yes.  Both transceiver types have wide-band
receivers.  Just be careful about tx/rx levels on each side: if your RX
levels are outside recommended parameters, you may end up damaging the
transceiver.
