- Fast Response & Delivery
- Professional Technical Support
The FC-LINK QSFP-DD 400G (4x100G) 1310nm 500m DR4 MPO8/12 Transceiver is a high-performance 400Gb/s Quad Small Form Factor Pluggable-double density (QSFP-DD) optical module, ideal for optical communication applications over distances of up to 500m. The module converts 8 channels of 50Gb/s (PAM4) electrical input into 4 parallel optical signals, each supporting 100Gb/s, for a total data rate of 400Gb/s. On the receiver side, it reverses the process, converting 4 channels of 100Gb/s optical signals back into 8 channels of 50Gb/s (PAM4) electrical output.The module is compatible with MTP/MPO-12 connector optical fiber cables, ensuring precise alignment through guide pins inside the receptacle. To maintain proper channel-to-channel alignment, the cable should not be twisted. Electrical connectivity is achieved via an edge-type connector compliant with the QSFP-DD MSA standard.Designed with a compact form factor, robust optical and electrical connections, and a digital diagnostic interface, this transceiver is a reliable solution for high-speed, short-range data communication applications.
