3AL82072AA Nokia Compatible 100G QSFP28 LR4 10km SMF Transceiver

Dropping in the 3AL82072AA is a like-for-like replacement for the Nokia part of the same number: a 100G QSFP28 LR4 optic reaching 10km over single-mode fiber. The two specs that pin the swap — the QSFP28 form factor and the 10km SMF LR4 budget — match the original exactly, so port maps and duplex LC patching stay as they are. At 100G over a 10km span, it serves the campus and inter-site links the OEM module was carrying.
