Mellanox ® MFS1S90-HxxxE is a QSFP56 VCSEL-based (Vertical Cavity Surface-Emitting Laser), cost-effective, 2x200Gb/s to 2x200Gb/s active optical splitter cable (AOC) designed for use in 200Gb/s InfiniBand HDR (High Data Rate) systems.It provides cross-connectivity between a 200G Top of Rack (ToR) switch port configured as 2x100G ports and two 200G spine switch ports also configured as 2x100G ports. This offers a substantial CAPEX saving by reducing the required number of spine ports and cables. For data centers with more than 1600 servers, it will also save the third layer switches.Each QSFP56 end of the cable comprises an EEPROM providing product and status monitoring information, which can be read by the host system. Rigorous production testing ensures the best out-of-the-box installation experience, performance and durability.Mellanox''s unique quality active fiber cable solutions provide power-efficient connectivity for data center interconnects. It enables higher port bandwidth, density and configurability at a low cost, and reduced power requirement in the data centers.
