1Gbps transceiver inside ISR4461 10GE port

[Bojan Zivancevic]

I would like to know whether I can put 1Gbps transceiver into 10GE SFP+ port on an ISR4461 router. I cannot find the exact info inside the docs. The transceiver would probably have to be a GLC-LH-SM - maybe GLC-SX-MMD but this should not make a difference.

Yes, you can.

[Joseph W. Doherty]

As already noted by Leo, yes you can. The SFP+ port supports gig or 10g SFP transceivers. However, you should check the support matrix for the specific transceivers supported (Cisco doesn't always support all the transceivers, even when they are the same speed).
