two single-mode fiber cores. The JT-QSFPDD-400G-FR4
supports a transmission distance of up to 2 kilometers. It is
compliant to IEEE 802.3bs, 400GBASE-FR4 Spec of 100G Lambda
MSA group, and 400GAUI-8/CEI-56G-VSR-PAM4 standards.
JTOPTICS® 400Gbps-LR4 transceiver module is a 400Gb/s
Quad Small Form Factor Pluggable-double density (QSFP-
DD) optical module 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.
Reversely, 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 module offers
very high functionality and feature integration, accessible
via a two-wire serial interface.
