400G QSFP-DD DR4 1310nm 500m PAM4 SMF MTP/MPO-12 FEC Transceiver Module
QDD-400G-DR4 Compatible 400GBase-DR4 QSFP-DD 1310nm 500m DOM MPO SMF Optical Transceiver Module
The QSFPDD-400G-DR4 is a 400Gb/s Quad Small Form Factor Pluggable-double density (also called as SFP56-DD) optical module designed for 500m optical communication applications. The module converts 8 channels of 50Gb/s (PAM4) electrical input data to 4 channels of parallel optical signals, each capable of 100Gb/s operation for an aggregate data rate of 400Gb/s. Reversely, on the receiver side, the module converts 4 channels of parallel optical signals of 100Gb/s each channel for an aggregate data rate of 400Gb/s into 8 channels of 50Gb/s (PAM4) electrical output data.
An optical fiber cable with an MTP/MPO-12 connector can be plugged into the QSFP-DD DR4 module receptacle. Proper alignment is ensured by the guide pins inside the receptacle. The cable usually cannot be twisted for proper channel to channel alignment. Electrical connection is achieved through an QSFP-DD MSA-compliant edge type connector.
The QSFPDD-400G-DR4 is designed with form factor, optical/electrical connection and digital diagnostic interface according to the QSFP-DD Multi-Source Agreement (MSA) Type 2. It has been designed to meet the harshest external operating conditions including temperature, humidity and EMI interference.
