The T1-QSFP-DD-400G-SR8 is a parallel 400Gb/s Quad Small Form Factor Pluggable–double density (QSFP-DD) optical module that provides increased port density and total system cost savings. The QSFP-DD full-duplex optical module offers 8 independent transmit and receive channels, each capable of 53.125Gb/s operation for an aggregate data rate of 400Gb/s on 100 meters of OM3 multi-mode fiber.
An optical fiber cable with an MTP/MPO-16 connector can be plugged into the QSFP-DD SR8 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 a QSFP-DD MSA-compliant edge-type connector. The central wavelengths of all 8 parallel lanes are 850nm.
It contains an optical MPO-16 connector for the optical interface and a 60-pin connector for the electrical interface. Host FEC is required to support up to 70m OM3 multi-mode fiber transmission. The product is designed with form factor, optical/electrical connection, digital diagnostic interface according to the QSFP-DD Multi-Source Agreement (MSA) Type 2, and to meet the harshest external operating conditions including temperature, humidity, and EMI interference.
