SFP28 transceiver CBO 25G-SFP28-TWX-P-0201-BL 25 Gbit/s, 2 m twinax copper cable

The SFP28 transceiver CBO 25G-SFP28-TWX-P-0201-BL is a 25 Gbit/s direct-attach copper solution with an integrated 2 m twinax cable. Intended for short-reach interconnects, this SFP28 module delivers a low-latency, point-to-point link between servers, switches and storage devices at rack and row levels. The compact SFP28 form factor makes it compatible with SFP28 ports and hot-pluggable environments, enabling quick installation and straightforward cabling for data center and enterprise topologies.

Advantages

This direct-attach SFP28 transceiver offers a cost-effective alternative to optical modules for short distances, reducing the need for separate patch cables and optical transceivers. The integrated twinax copper cable minimizes signal loss and latency over the 2 m distance, while the SFP28 form factor supports hot-swap replacement and simple port-level upgrades. The pre-terminated cable reduces installation time and simplifies inventory management compared with separate transceivers and fiber/copper cables.

Suitable for

• Short-reach server-to-switch and switch-to-switch connections within racks
• Top-of-rack and end-of-row data center interconnects
• High-performance storage area network links over short distances
• Environments where low latency and cost-efficiency are required

Key specifications

• Data rate: 25 Gbit/s full duplex
• Connector and form factor: SFP28 direct-attach with integrated twinax cable
• Cable length: 2 meters
• Media type: Twinax copper, shielded
• Typical use: Short-reach, direct-attach connections
• Operating mode: Hot-pluggable module for SFP28 ports

How to use

Install the SFP28 transceiver into an available SFP28-compatible port until it clicks into place, then connect the integrated twinax cable to the corresponding port on the remote device. Ensure both devices are powered and configured for 25 Gbit/s operation if required by the host firmware or switch settings. No external optical transceivers or additional patch cables are required; the unit is intended for direct-attach use and supports immediate link negotiation once inserted and enabled.

Recommendations

Use this direct-attach SFP28 module for short, rack-level connections up to 2 m where copper DACs provide lower cost and latency than optical solutions. Verify compatibility with your switch or server vendor's supported transceiver list and ensure proper handling to avoid stress on the integrated cable or connector during installation and maintenance.
