0.5m (1.64ft) Cisco Q56-200-CU50CM Compatible PAM4 QSFP56 to QSFP56 DAC 200GBASE-CR4 200Gbps Passive Direct Attach Twinax Copper Cable
Cisco Q56-200-CU50CM compatible DAC is a passive 200Gbps QSFP56 to QSFP56 direct attach cable for use in 200GBASE Ethernet network. QSFP56 DAC provides 212.5Gb/s throughput for 0.5m interconnection with high speed twin-axial copper cable. This DAC is fully compliant with QSFP56 Multi-Source Agreement (MSA), IEEE 802.3cd 200GBASE-CR4 and 200GAUI-4 standard. Its twin-axial copper cable’s wire gauge is 30AWG and pre-terminated with MSA compliant 38-pin edge type connectors. The DAC cable implements 4 independent 53.125Gbps PAM4 transmit and receive signal channels in each differential pair for an aggregate 212.5Gbps data rate. It also supports 4 channels 25.78125Gbps NRZ signals for 103.125Gbps interconnection. Standard length options cover from 0.5 meters to 3 meters. MSA memory map is accessible via 2-wire (TWI/I2C) interface. Our DACs are factory pre-programmed for compatibility, perform alternatively to genuine Cisco Q56-200-CU50CM direct attach cables.
