Product Description
200G-SR4 QSFP56 is a Multi-Vendor MSA Compatible 200GBASE-SR4 QSFP56 (Quad Small Form-Factor Pluggable) Transceiver designed for operation over Multi-Mode Fiber (MMF). 200G-SR4 QSFP56 has a QSFP form factor, built in 200G PAM4 (Pulse Amplitude Modulation 4-level) DSP (Digital Signal Processor) and module supports four electrical interface lanes, which can operate in 50G PAM4 encoding mode resulting in 200G (4x50G) data rate. 200GBASE-SR4 QSFP56 module becomes handy in Data Center environments where we would need to connect multiple 200G signals from the server side (NICs) to the Data Center aggregation switch. Module has a minimum guaranteed optical budget of 1.9 dB, which in most cases is enough to reach 100 m over OM4 multimode fiber, or 70 m over OM3 multimode fiber with FEC support. However, distance is just an indicative parameter calculated for comfort of identification. Eventually we calculate distance taking in account minimal optical budget and average attenuation of optical cabling in industry. 200G-SR4 QSFP56 uses 4 channel 53.125 Gbps VCSEL (Vertical Cavity Surface Emitting Laser) 850 nm transmitters and 4 channel 53.125 Gbps PIN 850 nm photodiode receivers. Module supports DDM/DOM optical diagnostics, which provide diagnostic information about the present operating conditions. 200GBASE-SR4 QSFP56 operates in the standard 0°-70°C temperature range and has an MPO/MTP-12 PC optical connector and 38 pins F-tone Networks connector for electrical interface. 200GBASE-SR4 QSFP56 supports 212.5 Gbps data rate and such applications as 200G Ethernet.
