## Summary description

Passive copper SFP28 twinax direct attach cable (DAC) by CBO, model SFP28-DAC-1M-VA-BL, 1 meter length. Designed for short-reach 25GbE connections between SFP28 ports on switches, NICs and storage devices. Provides low-latency, power-efficient connectivity with a fixed cable form factor for rack- and chassis-based networking equipment.

## Long description

The CBO SFP28 Passive Copper Twinax Cable 1m is a fixed-form direct attach cable designed for short-reach 25GbE links between SFP28 ports on switches, network interface cards and storage devices. This 1 meter passive copper twinax solution provides a low-latency, energy-efficient connection when high-speed optical transceivers are not required. The integrated SFP28 connectors and shielded twinax conductor deliver consistent electrical performance in rack- and chassis-based network environments.
Advantages
This passive SFP28 twinax cable offers a cost-effective option for short-distance 25 Gigabit Ethernet interconnects, reducing power consumption compared with active optical solutions. Its fixed 1 m length simplifies cable management in dense rack deployments, while the copper twinax construction provides stable signal integrity and low latency. The cable’s direct attach form factor eliminates the need for separate transceivers, enabling plug-and-play installation on compatible SFP28 ports.
Suitable for
Connecting SFP28 ports between switches in data center racks
Direct links from servers or NICs to top-of-rack switches
Short-reach interconnects for storage arrays and appliance modules
Key specifications
Interface: SFP28 to SFP28 direct attach cable
Data rate: 25 Gigabit Ethernet
Length: 1 meter
Cable type: Passive copper twinax with integrated shielding
Form factor: Fixed direct attach cable (DAC)
Typical application: Short-reach rack/chassis interconnects
How to use
Insert each SFP28 connector into the corresponding SFP28 port until the latch engages. Ensure both network devices are powered and configured for 25GbE operation and that link negotiation settings on switches and NICs match the intended speed and duplex. For proper operation, avoid bending the cable sharply near the connector heads and verify the cable is seated fully in each port. No additional transceivers or power sources are required for passive operation.
Usage recommendations
Route the cable to minimise stress on connectors, maintain recommended bend radius, and keep twinax runs within rack cable management channels. Use this passive SFP28 twinax cable for short-distance links inside single racks or between adjacent racks where 1 m length is sufficient. Confirm compatibility with device vendor documentation for supported passive DACs and SFP28 port firmware.
