## Summary description

Passive SFP28 direct attach copper (DAC) cable by CBO, model SFP28-DAC-1M, 1 meter length. Designed for short-reach 25GbE connections between compatible SFP28 ports in switches, servers and storage. Provides low-latency, low-power physical link without optical transceivers, suitable for data center top-of-rack and server-to-switch links.

## Long description

BlueOptics SFP28 Passive Copper DAC Cable CBO SFP28-DAC-1M 1 m is a 1‑meter passive direct attach copper (DAC) assembly designed for short‑reach 25 Gigabit Ethernet (25GbE) links. The cable provides a physical electrical connection between compatible SFP28 ports on switches, servers and storage devices without requiring optical transceivers. It is intended for data center top‑of‑rack, server‑to‑switch and similar short‑distance interconnect applications where low latency and low power consumption are required.
Advantages
This passive SFP28 DAC cable delivers predictable latency and reduced power draw compared with optical transceivers, while simplifying port connectivity by offering a one‑piece electrical link. The fixed 1 m length minimizes signal attenuation for short runs and eliminates the need to provision and manage separate optical modules and fiber patch cords. The assembly is backward compatible with SFP28 ports designed for 25GbE and supports hot‑plug insertion, enabling simple deployment and replacement in rack environments.
Suitable for
 Top-of-rack connections between switches and servers
 Server-to-switch links within the same rack
 Short-reach links in storage and hyperconverged systems
 Environments where low latency and low power per port are priorities
Key specifications
 Interface: SFP28 to SFP28 electrical direct attach copper
 Data rate: 25 Gigabit Ethernet (25GbE) signaling
 Length: 1 meter
 Cable type: Passive twinax copper assembly
 Connector: SFP28 metal cage with latch for hot‑plug operation
 Typical use: Short‑reach rack and intra-rack connections
How to use
Power off equipment if required by your site procedures, then insert the SFP28 connector into the SFP28 port until the latch engages. Connect the other end to the corresponding SFP28 port on the remote device. Verify link status via the host device management interface or LED indicators. For hot‑swapping, follow platform guidance for safe insertion and removal to avoid network disruption. No additional configuration is required at the physical layer beyond ensuring compatible port settings (25GbE or negotiated speed).
Usage recommendations
Use this 1 m passive DAC cable for short, direct server-to-switch and switch-to-switch connections within racks. Avoid bending the cable sharply near the connectors, keep the assembly away from sources of strong electromagnetic interference, and follow your equipment vendor’s compatibility list to ensure full interoperability with specific switch and server models.
