WaveSplitter’s 400-Gbps QSFP-DD SR8 Optical Transceiver 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 design to follow QSFP DD MSA and 200GBASE-SR4 of IEEE 802.3cd and IEEE P802.3bs 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 optical 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 data center.
