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

For campus and inter-building 40G, LR4 keeps things simple: one duplex LC connection, ten kilometers of reach, and full compliance with both Ethernet and OTU3 transport standards.

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.
