Something that has frustrated me in the past is using the cumbersome method of determining the connectors required to terminate a particular optic’s fibres. We would determine the optic part code (show inventory, show module, etc) and then looked up the partcode on CCO. This was incredibly inefficient and I always felt that there had to be a way of doing this through the command line so, after many CCO documents, I found the following.
show idprom int <interface>
will show the connector type.

The following is an output from a 7600. The cards in slot 1 and 2 are LAN based (67xx) cards. The ES+ in slots 3 and 4 are Ethernet Services cards, which behaves less like a classic LAN interfaces and more like a genuine router interface, with support for CBWFQ / MQC and other features commonly found on Cisco’s software router platforms, such as a 7200.

Some examples (filtered just to show the relevant connector lines):
Router#show idprom int tengig 1/1 | i connector Optical connector type :0x1 =SC Router#show idprom int gig 2/1 | i Connector Connector : LC [0x07] Router#show idprom int tengig 3/1 | i Connector Connector type = LC. Router#show idprom int tengig 4/1 | i Connector Connector type = LC.
CRS
CRS is (of course) different:
RP/0/RP0/CPU0:Router#show diag 0/0/CPU0 | i Connector Fri Jul 1 13:45:21.768 UTC Connector type: SC
With these commands you’ll be able to determine what your connector types are without referring to product sheets.
