The Color Optic CO-ACQ100-4S25-x is QSFP28 4-channel active optical cables (AOC) for 100G Ethernet (100GbE) applications. This full-duplex optical assembly offers 4 independent transmit and receive channels, each capable of up to 25Gbps for an aggregate bandwidth of 100Gbps. The 100G QSFP28 AOC cables can be used as a direct replacement for traditional QSFP28 DAC (direct attach copper cables) and QSFP28 transceivers of short reach while providing lighter weight, improved signal integrity, lower cost, and performance value. The optical end is never exposed to a data center environment and therefore does not require cleaning or special handling. They are designed expressed for high speed, high density and low power consumption for today’s data center networking applications.
