Cisco QSFP-40GE-LR4 Transceiver Module – 40GBASE-LR4 1310nm Duplex LC 10km
The Cisco QSFP-40GE-LR4 is a 40GBASE-LR4 QSFP+ optical transceiver designed for long-reach 40 Gigabit Ethernet connectivity over single-mode fiber. It operates in the 1310nm optical window using four CWDM optical lanes that are multiplexed and demultiplexed within the module.
The module supports up to 10km over standard G.652 single-mode fiber and uses a duplex LC connector. A key distinction of the QSFP-40GE-LR4 is its support for both 40 Gigabit Ethernet and OTU3 data rates, making it suitable for compatible Cisco optical networking and transport applications.
