Tecowin Juniper EX 10GBase Direct Attach Copper Cable, 3m, SFP+ to SFP+, Passive Twinax, Black

This Tecowin DAC cable is a passive twinax direct attach copper assembly built for Juniper EX switches. It links SFP+ ports over 3 meters without the cost and power draw of optical transceivers, delivering a stable 10 Gigabit Ethernet link in dense racks.

Highlights

• Passive twinax design consumes under 0.1W, reducing switch power and cooling load.
• 30 AWG conductors and 100 Ohm impedance maintain signal integrity across the full 3m length.
• Hot-swappable SFP+ connectors allow fast replacement without downtime.
• Black PVC jacket is durable and easy to route in cable management arms.

In daily use

The cable is plug-and-play with Juniper EX Series switches. It is ideal for top-of-rack to server connections, storage networks, or stacking links where short, high-bandwidth copper is preferred over fibre. The passive design means no active electronics, so there is no added latency or failure point.
