Gearlink's 400-Gbps QSFP-DD DR4 Optics Transceiver Module 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 MPO QSFP DD MSA and 400GBASE-DR4 of IEEE 802.3bs standard and ultra-low power consumption of 8 W for 400G QSFP-DD D`R4+ are also proven.

Compared with the conventional copper-based direct attach cables (DACs), the 400g dr4 optical fiber with pluggable MPO connector enables the ease of complicated data center cabling deployment by the longer, lighter, and bendable characteristics. The 400g dr4 transceiver utilizes high-performance 1310-nm EML 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.
