BlueOptics D-Link DEM-CB100S28 BlueLAN 25GBASE-CR SFP28 a SFP28 Direct Attach cable de cobre, 1 metro

The BlueOptics D-Link DEM-CB100S28 BlueLAN 25GBASE-CR passive SFP28 to SFP28 direct attach copper cable provides a high-performance, cost-effective interconnect solution for 25 Gigabit Ethernet networks. Designed as a compatible alternative to the D-Link DEM-CB100S28, this 1-meter passive twinax copper cable delivers reliable, low-latency connectivity between SFP28 ports in data centers and enterprise environments.

Advantages

This direct attach cable eliminates the need for separate transceivers and fiber optic cabling, reducing cost and complexity. Its passive design ensures near-zero power consumption (<0.1W) and minimal heat generation, making it ideal for high-density deployments. The cable is hot-swappable and fully compliant with 25GBASE-CR standards, guaranteeing interoperability with all SFP28 ports.
