JTOPTICS® QSFPDD 200GBASE-FR4 is engineered for utilization in 200 Gigabit Ethernet connections across single-mode fiber networks. This module is capable of converting 4-channel 53.125 Gbps electrical data into 4-channel optical signals, subsequently multiplexing them into a single channel for 212.5 Gbps optical transmission. On the receiving end, it performs optical de-multiplexing of a 212.5 Gbps input into 4-channel signals, converting them back to 4-channel output electrical data. Hot-pluggable QSFP56 form factor Built-in 200G PAM4 DSP Supports 212.5Gb/s aggregate bit rates Low power dissipation < 6W Commercial case temperature range of 0°C to 70°C Single 3.3V power supply Maximum link length of 2km on SMF 4 channels DML TOSA (uncooled) 4 channels PIN ROSA 4 CWDM lanes MUX/DEMUX design LC duplex connector 200GAUI-4 electrical interface Complian..
