# Product Documentation
Arista Compatible QSFP-200G-SR4 Datasheet - 200G-QSFP56-100

Our version of Arista Compatible QSFP-200G-SR4 Datasheet is based on our product 200G-QSFP56-100. When You will order it will be encoded to be compatible with Arista equipment and it will be labeled with part number: 200G-QSFP56-100-AR, where AR means Arista Compatible. Above You can download datasheet of our 200G-QSFP56-100 product.

# Product Description

QSFP-200G-SR4 is a Arista Compatible 200GBASE-SR4 QSFP56 (Quad Small Form-Factor Pluggable) Transceiver designed for operation over Multi-Mode Fiber (MMF). QSFP-200G-SR4 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. Arista compatible QSFP-200G-SR4 operates in the standard 0°-70°C temperature range and has an MPO/MTP-12 PC optical connector and 38 pins edge connector for electrical interface. 200GBASE-SR4 QSFP56 supports 212.5 Gbps data rate and such applications as 200G Ethernet.

To ensure compatibility we have tested our compatible version of Arista QSFP-200G-SR4 Transceiver in latest platforms of Arista networking equipment, which allows us to encode transceiver EEPROM memory to be compatible and work seamlessly with Arista platforms. Transceivers is also CE/RoHS certified, compliant with product safety standards and is fully compliant to 200GBASE-SR4 QSFP56 Multi Source Agreement (MSA), where IEEE Std 802.3bs defines physical layer specifications 200GAUI-4 electrical interface, IEEE 802.3cd defines four-lane 200 Gbit/s PHYs operation over Multi-Mode Fiber (MMF) with lengths up to 100 meters, SFF-8679 defines QSFP+ 4X Hardware and Electrical Specification and module is Common Management Interface Specification CMIS V4.0 compliant.
