BlueLAN Compatible 25G SFP28 Direct Attach Cable, 0.5m, Passive Copper Twinax CBL-NTWK-1215-05M-G-BL

High-density 25G Ethernet links in racks and adjacent cabinets often suffer from bulky, power-hungry optical transceivers and fragile fiber patch cords. This 0.5-meter passive copper twinax direct attach cable replaces two SFP28 modules and a fiber pair with a single, robust assembly, cutting cost, latency, and power draw for short-reach interconnects.

Who is it for

Data center operators, network engineers, and system integrators connecting servers, switches, and storage devices at 25 Gigabit Ethernet over very short distances. It is ideal for top-of-rack to end-of-row links where a 0.5-meter reach is sufficient and power efficiency is critical.

Tips

For best signal integrity, keep the bend radius of the twinax cable above the manufacturer's minimum and avoid placing the cable near sources of electromagnetic interference. This cable is intended for intra-rack or adjacent-rack connections; for longer distances, consider active optical cables or fiber transceivers.
