25Gbps SFP28 Active Optical Cables(GZS2X-AOC-x)

GZS2X-AOC-x

Product Description：

25Gbs AOC Cable 0.5-100m cable is a high speed, cost-effective 25Gbp/s Ethernet connectivity solution designed to meet the growing needs for higher bandwidth in data centers.It contains a single high-speed copper pair, operating at data rates of up to 25 Gb/s. The cables are compliant with IEEE 802.3by Ethernet standard and SFF-8402 SFP28 standard. Each SFP28 connector comprises an EEPROM providing product information which can be read by the host system.Our unique quality passive copper cable solutions provide 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 production testing ensures the best out-of -the-box installation experience, performance, and durability.
