BlueOptics 02311MNX Compatible BlueLAN QSFP28 DAC Cable 1m 02311MNX-BL

This QSFP28 direct attach copper cable delivers 100Gbps connectivity in a passive design that consumes less than 0.5W per end. Unlike active optical cables, it needs no signal conditioning and introduces no added latency, making it a straightforward choice for short-reach links inside racks and across adjacent cabinets.

Highlights

• 100GBASE-CR4 Ethernet and InfiniBand support
• QSFP28 to QSFP28 connectors, hot-pluggable
• 30 AWG passive copper, 100 Ohm impedance
• 1 meter length, black PVC jacket
• Operating temperature 0°C to 70°C

In daily use

The cable is MSA-compliant and coded for BlueLAN equipment, so it is recognised by compatible switches and network adapters without additional configuration. The passive design keeps power draw low and avoids the heat generated by active transceivers, which helps maintain stable thermal conditions in dense racks.
