SFP28 Direct Attach Cable CBO 2m for Juniper 740-086863 — 25Gb/s copper twinax

SFP28 Direct Attach Cable CBO 2m for Juniper 740-086863 — 25Gb/s copper twinax is a passive SFP28 twinax copper cable designed for short-reach interconnects between servers, switches and storage devices equipped with SFP28 ports. With a 2 meter length and support for 25 Gb/s per lane, this cable provides a low-latency, energy-efficient alternative to optical transceivers for rack-to-rack and top-of-rack connections in data centre environments.

Advantages

The passive twinax construction reduces latency and power consumption compared with active optical modules, while maintaining reliable high-speed connectivity at 25 Gb/s. A fixed 2 m length simplifies cable management in dense rack deployments. Compatibility with SFP28 ports ensures straightforward hot-plug installation without additional drivers or configuration changes on supported network devices.

Suitable for

• Short-reach server-to-switch interconnects in data centres
• Top-of-rack (ToR) and rack-to-rack links
• High-throughput storage networking and aggregation ports
• Low-latency environments where reduced power and heat are important

Key specifications

• Interface: SFP28 to SFP28 (direct attach copper twinax)
• Length: 2 meters
• Data rate: 25 Gb/s per lane
• Cable type: Passive twinax copper
• Typical use: Short-reach links within racks or between adjacent racks
• Connectors: SFP28 form factor compatible with standard SFP28 ports

How to use

Install the cable by inserting each SFP28 connector into the corresponding SFP28 port on the devices you intend to link. Ensure both devices are powered and that ports support 25 Gb/s SFP28 direct attach copper connections. No additional configuration or software is normally required; the connection should be recognised by the host devices and appear as a standard network link. Route the cable to avoid sharp bends and maintain the recommended bend radius to preserve signal integrity.

Recommendations

For optimal performance, use this 2 m passive twinax cable for connections within the same cabinet or between adjacent cabinets. Avoid repeated mechanical stress on the connectors, keep the cable clear of cable management pathways that impose excessive bending, and verify port compatibility with your network equipment vendor documentation before deployment.
