BlueOptics SFP28-DAC-2M-TL-BL Compatible BlueLAN DAC SFP28 2m Passive Twinax Cable Black

The BlueOptics SFP28-DAC-2M-TL-BL is a high-performance, passive Direct Attach Copper (DAC) cable designed for 25 Gigabit Ethernet (25GbE) connections. This 2-meter cable features SFP28 connectors on both ends, providing a reliable, low-latency, and cost-effective interconnect solution for data centers, server-to-switch links, and network storage environments. It is MSA compliant and compatible with a wide range of networking equipment from leading vendors such as Cisco, Juniper, Arista, Mellanox, HPE, and Dell.

Advantages

This DAC cable offers superior signal integrity and low power consumption (<0.1W) compared to optical transceivers, making it an energy-efficient choice for high-density deployments. The passive twinax design ensures zero latency and no signal processing, ideal for high-frequency trading and real-time applications. Its hot-swappable capability simplifies maintenance and upgrades without network downtime.
