Arista QDD-400G-SR8 Compatible 400GBase-SR8 QSFP56-DD 850nm 100m DOM MPO MMF Optical Transceiver Module
Product Description:
The Coloroptic's CO-QD4H85S8C is a parallel 400Gb/s Quad Small Form Factor Pluggable--double density (QSFP56-DD) optical module. It provides increased port density and total system cost savings. The QSFP56-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 QSFP56-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 an QSFP56-DD MSA-compliant edge type connector.
The central wavelengths of all the 8 parallel lanes are 850nm. The CO-QD4H85S8C 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 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.
