Product description

Hilink QSFP28 Optical Transceiver Module 100G  4Channels CWDM4 QSFP28 2KM dual LC Single mode

100G Hilink QSFP28 CWDM4 is designed to operate over single-mode fiber system using 4X25 CWDM channel in 1310 band and links up to 2km. The hilink module converts 4 inputs channel of 25Gb/s electrical data to 4 CWDM optical signals, and multiplexes them into a single channel for 100Gb/s optical transmission.
Reversely, on the receiver side, the module optically de-multiplexes a 100Gb/s input into 4 CWDM channels signals, and converts them to 4 channel output electrical data.

The central wavelengths of the 4 CWDM channels are 1271 nm, 1291 nm, 1311 nm and 1331 nm. 

It contains a duplex LC connector for the optical interface and a 38-pin connector for the electrical interface. Single-mode fiber(SMF) is applied in this module.
