Cisco QSFP-40G-LR4 Compatible 40GBASE-LR4 QSFP+ 1310nm 10km DOM Duplex LC SMF Optical Transceiver Module

Four wavelengths at 1271, 1291, 1311 and 1331nm share a single fiber pair, so this module lifts existing duplex single-mode plants straight to 40G.

Because it uses duplex single-mode fiber, the LR4 upgrades installed 10G cable plants to 40G without re-cabling, cutting both cost and deployment time for inter-building links.
