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.
The design follows the QSFP+ MSA, IEEE 802.3ba 40GBASE-LR4 and OTU3 C4S1-2D1 mappings, letting the same hardware serve Ethernet and optical transport roles in carrier networks.
