Sky Optics releases 100G QSFP28 Direct Attach Cable (DAC)

Time:2018-06-22 Views:302

QSFP28 Direct Attach Cables are compliant with the SFF-8665 specifications. Various choices of wire gauge are available from 30 to 24 AWG with various choices of cable length (up to 5m).

Designed for applications in the data center, networking and telecommunications markets that require a high speed, reliable cable assembly, this next generation product shares the same mating interface with QSFP+ form factor ,making it backward compatible with existing QSFP ports.QSFP28 can be used with current 10G and 14G applications with substantial signal integrity margin.

The 100G QSFP28 to 4SFP28 passive copper cable assembly feature eight differential copper pairs, providing four data transmission channels at speeds up to 28Gbps per channel, and meets 100G Ethernet,25G Ethernet and nfiniBand Enhanced Data Rate(EDR) requirements. Available in a broad rang of wire gages-from 26AWG through 30AWG-this 100G copper cable assembly features low insertion loss and low cross talk.
