TK 400G QSFP-DD LR4 CWDM 10KM Optical Transceiver For Telecommunication System
TK 400G QSFP-DD LR4 Overview

This 400Gb/s QSFP-DD optical module is designed for 10km optical communication applications. The module converts 8 channels of 50Gb/s (PAM4) electrical input data to 4 channels of


CWDM optical signals and multiplexes them into a single channel for 400Gb/s optical transmission.

On the receiver side, the module optically de-multiplexes a 400Gb/s optical input into 4 channels of CWDM optical signals and converts them to 8 channels of 50Gb/s (PAM4) electrical output data.


The central wavelengths of the 4 CWDM channels are 1271, 1291, 1311 and 1331 nm as members of the CWDM wavelength grid defined in ITU-T G.694.2. Host FEC is required to support up to 10km fiber transmission.
