InfiniBand/fibre optic cable BlueOptics JL294A-BL 1 m SFP28 Black

The BlueOptics JL294A-BL is a 1 m InfiniBand/fibre optic cable equipped with SFP28 connectors on both ends, designed to support high-speed data transmission and low-latency connections in networking and data centre environments. This single-mode/multi-mode compatibility depends on the connected transceivers and system configuration; the cable itself provides a compact, robust link for SFP28 ports at short reach. It is intended for direct attachment between compatible SFP28 ports where a 1-metre length and a flexible, low-profile cable are required.

Advantages

The cable combines SFP28 connector compatibility with a slim, durable jacket that reduces clutter and improves airflow in rack installations. Its 1 m length is suitable for short interconnects inside switches, servers and storage enclosures, minimising excess cable while maintaining signal integrity. Designed for consistent electrical and optical performance, the cable supports high-bandwidth applications and is built to meet the mechanical demands of frequent insertion and removal.

Suitable for

• Short-reach interconnects between SFP28-enabled switches, servers and storage devices
• High-bandwidth InfiniBand or fibre optic links in data centres and server rooms
• Cabinet and rack-level connections where a 1 m cable minimises cable management complexity

Key specifications

• Cable length: 1 metre
• Connector type: SFP28 on both ends
• Cable colour: black (outer jacket)
• Intended use: high-speed data transmission and low-latency links
• Form factor: slim, low-profile jacket for improved airflow

How to use

Ensure both devices have compatible SFP28 ports and appropriate transceivers or modules if required by the host hardware. Align and insert each SFP28 connector into the corresponding port until it locks. Route the cable to avoid sharp bends and to maintain recommended bend radius for fibre optic or high-speed copper constructions. Verify link status on connected equipment and test throughput and error rates as part of integration into the network.

Recommendations

Use the cable for short, direct connections inside racks and enclosures; avoid long runs beyond the supported reach of SFP28 links for reliable signal performance. Maintain gentle bends, secure the cable to reduce strain on connectors, and inspect connectors for contamination before insertion to ensure optimal connectivity.
