If you are using CWDM SFP transceivers, use an LC-to-LC patch cable.
If you are using CWDM GBIC transceivers, you must use an SC-to-LC patch cable
(CAB-SM-LCSC-1M= or CAB-SM-LCSC-5M=).
CWDM GBIC transceivers are equipped with SC connectors. To make connections to the LC
connectors on the OADM modules, you must use an LC to SC patch cable (Cisco part number
CAB-SM-LCSC-1M= [1 meter cable], CAB-SM-=LCSC-5M= [5 meter cable], or an equivalent
patch cable).
Always use single-mode fiber-optic patch cables to connect the CWDM OADM ports to the
CWDM GBIC transceivers or CWDM SFP transceivers.
