Determine SFP-Type ASR920

[m.x]

Helllo,

From the 'show inventory' command on a ASR920-112-CZ-A I get the follwing response:

NAME: "Chassis", DESCR: "Cisco ASR920 Series - 12GE and 2-10GE - AC model"
PID: ASR-920-12CZ-A , VID: V05 , SN:

NAME: " FIXED IM subslot 0/0", DESCR: "FIXED : 12-port Gig & 2-port Ten Gig Dual Ethernet Interface Module"
PID: 12xGE-2x10GE-FIXED, VID: V00 , SN: N/A

NAME: "subslot 0/0 transceiver 13", DESCR: "1000BASE BX10-U"
PID: GLC-BX-U , VID: V02 , SN:

The BX10-U implies that it is a 10G right? The 1000BASE is confusing me. I'm asking because the connection is not working. On the other end is a 1g GLX-D. 

Am I wrong?

The prefix is GLC therefore 1 Gbps only. 

10 Gbps is SFP-10G-BXU or SFP-10G-BXD.

Hello @m.x,

1000BASE BX10-U

1000 base stand for 1G. The 10 is for 10km ! On the other extremity you should have 1000BASE BX10-D.

Hello @m.x ,

the GLC-BX-U is 1GE of a special type that works on a single fiber cable .

see

https://www.ciscotransceivers.com/glc-bx-u

It works by using two different wavelenghts for TX and RX and it requires a special SFP on the other side that uses those two wavelengths in a symmetric manner

module for single-strand SMF,

on the other side you would need a GLC-BX-D

if you have two fiber cables a standard pair you can use two standard SFPs instead of this.

Hope to help

Giuseppe

Wow, thanks you for the responses. Super helpful! I know not that it's not a type conflict. divide and concquer right! Thanks again!
