The Hilink HL-QDD-400G-SR4 is a 400Gb/s Quad Small Form Factor Pluggable-double density (QSFP-DD) optical module engineered for 100-meter optical communication applications. This advanced transceiver converts 8 channels of 50Gb/s (PAM4) electrical input data to 4 channels of optical signals, multiplexing them into a single channel for 400Gb/s optical transmission. On the receiver side, it optically de-multiplexes a 400Gb/s optical input into 4 channels and converts them back to 8 channels of 50Gb/s electrical output data.
Key Features
QSFP-DD MSA Compliant
CMIS compliance
Optical Interface: IEEE 802.3db compliant
Electrical Interface: IEEE 802.3 2022 400GAUI-8
