MCP7F00-A0xxRyyz cables are compliant with SFF-8402 SFP28 and SFF-8665 QSFP28 standard specifications and provide connectivity between system units with a QSFP28 port on one side and up to four different SFP28 ports on the other.
The cable connects data signals from each of the 4 copper pairs on the QSFP28 end to the single pair of each of the SFP28 ends. Each QSFP28/SFP28 port comprises an EEPROM providing product information which can be read by the host system. MCP7F00-A0xxRyyz cables up to 2m support IEEE 802.3by CA-25G-N (Cable Assembly No-FEC) with low latency.
Cables from 3m to 5m support IEEE 802.by CA-25G-L (Cable Assembly Long) with RS-FEC (Reed Solomon Forward Error Correction) enabled. For 2.5m and 3m cables there are two versions supporting either CA-25G-N or CA-25G-L. Mellanox’s unique quality passive copper cable solutions provide power-efficient connectivity for short distance interconnects. They enable higher port bandwidth, density and configurability at a low cost and reduced power requirement in the data centers. Rigorous cable production testing ensures best out-of-the-box installation experience, performance and durability.
