The cable connects the data signals from each of the two dual copper pairs on the single QSFP28 (pair 1&2, 3&4) end to the dual copper pair of each of the QSFP28 (pair 1&2) ends on the multiport side. Each QSFP28 port comprises an EEPROM providing product information, which can be read by the host system.
MCP7H00-G0 series cables up to 2m support IEEE 802.3by CA-25G-N (Cable Assembly No-FEC) with low latency. Cables with 4m length support IEEE 802.3by 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.
It enables 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.
