StarTech.com SFP-H10GB-CU3M | 3m Passive 10G SFP+ Twinax Cable

The StarTech.com Cisco SFP-H10GB-CU3M Compatible 3m 10G SFP+ to SFP+ Direct Attach Cable Twinax – 10GbE SFP+ Copper DAC 10 Gbps Low Power Passive Mini GBIC/Transceiver Module DAC… offers a reliable link for short-distance 10GbE connections. This passive Direct Attach Cable (DAC) is designed for high-density server and switch racks. It connects devices using SFP+ ports without needing separate transceivers. The cable supports the InfiniBand protocol, adding flexibility for specific network setups.

3m Copper Link for 10GbE Racks

This cable provides a direct copper connection between network devices. It supports data transfer rates up to 10 Gbps. The 3-meter length is ideal for top-of-rack switching or adjacent rack connections. Because it is a passive Twinax cable, it consumes very low power. This design helps reduce overall energy costs in busy data centres. The cable is also hot-swappable, allowing for maintenance without network downtime.
