Module (400G QSFP-DD SR8) with Quad Small Form-Factor Pluggable Double Density (QSFP-DD) form-factor is of high performance in bi-directional signal transmission and aggregate 400Gbps bandwidth, which is designed to follow QSFP DD MSA and 200GBASE-SR4 of IEEE 802.3cd standard.

 

Compared with the conventional copper-based direct attach cables (DACs), the optical fiber with pluggable MPO connector enables the ease of complicated data center cabling deployment by the longer, lighter, and bendable characteristics. the  transceiver module utilizes high-performance 850-nm GaAs VCSELs and PIN PDs with superior integration in signal integrity and optical sub-assembly, whose bit-error rate is better than 2.4 E-4 for reliable packet communication within the data center.

Notes of 400g sr8 transceiver:

 

1. Bit-Error-Rate (BER) is tested with the PRBS 31Q pattern.

 

2. 400G QSFP-DD SR8 requires an electrical connector compliant with QSFP-DD MSA which is used on the host board in order to guarantee its electrical interface specification.
