4m (13.12ft) Generic Compatible QSFP-56G-DAC26-4M 56G QSFP+ Passive Direct Attach Twinax Copper Cable

direcXource's QSFP-56G-DAC26-4M DAC is a passive 56Gbps QSFP+ to QSFP+ direct attach cable for use in 56G InfiniBand. QSFP+ DAC provides 56Gb/s throughput for 4m interconnection with high speed twin-axial copper cable. Standard length options cover from 0.5 meters to 5 meters. The QSFP+ DAC cable implements 4 independent 14 Gbps NRZ transmit and receive signal channels in each differential pair for an aggregate 56 Gbps data rate. This DAC is fully compliant with QSFP+ Multi-Source Agreement (MSA) and InfiniBand 4X FDR standard. The twin-axial copper cable's wire gauge is 26AWG and pre-terminated with MSA compliant 38-pin edge type connectors. MSA memory map are accessible via 2-wire Interface (TWI/I2C). Our DACs are factory pre-programmed for compatibility, perform identically to generic MSA direct attach cables.
