Cisco QSFP-100G-LR4-S Compatible 100GBASE-LR4 QSFP28 1310nm 10km OS2 DOM Duplex LC SMF Optical Transceiver Module

100G QSFP28 LR4 optical transceiver

The 100GBASE-LR4 QSFP28 module carries 100G over a standard duplex single-mode fiber pair for up to 10 kilometers, using four LAN-WDM wavelengths multiplexed inside the module. It is the workhorse for building-to-building and campus-scale 100G links, fully coded for Cisco QSFP-100G-LR4-S ports.

Four cooled DFB lasers around 1295.56, 1300.05, 1304.58 and 1309.14nm are combined onto one fiber, then separated at the receiver, so the module only needs a normal duplex LC connection. Per-channel optical monitoring is available through DOM, and the hot-pluggable QSFP28 form factor fits all compliant switch, router and transport ports. Each unit is tested on real switching platforms before it leaves our facility.
