Fibre optic cable Intel E25GSFP28LRX

The Intel E25GSFP28LRX is a fibre optic cable engineered for long-range InfiniBand and high-speed networking environments. Designed as part of Intel's optics and cables lineup, this cable provides reliable optical data transmission over extended distances and is suited to installations that require stable, low-latency links between network devices. Its construction supports high-performance computing and data centre topologies where signal integrity and distance are critical.

Advantages

The cable offers long-range capability, enabling connections across larger server rooms and between racks without intermediate repeaters. Its optical design minimises signal loss and supports sustained throughput for demanding workloads. Compatibility with common networking transceivers and equipment reduces integration complexity, while the durable jacket and connector assembly provide mechanical reliability in rack-mounted and routed installations.

Suitable for

• Data centre spine and leaf links
• High-performance computing clusters
• InfiniBand fabrics and low-latency networking
• Inter-rack and long-reach uplink connections

Key specifications

• Media type: single-mode fibre (long-range optical transmission)
• Connector type: SFP28-compatible optical interfaces
• Intended application: InfiniBand and high-speed Ethernet environments
• Design focus: low insertion loss and long-distance reach
• Construction: durable jacket and reinforced connector housing for rack use

How to use

Install the optic cable by gently inserting the SFP28-compatible connector into the corresponding transceiver port until it latches. Route the cable through cable management channels to avoid sharp bends and excessive tensile stress, maintaining the minimum bend radius specified by the equipment manufacturer. Verify link negotiation and optical signal levels from the host interfaces or management software to ensure proper operation. When disconnecting, depress the latch mechanism before removing the connector to prevent connector or port damage.

Recommendations

Store and handle the cable in a clean, dry environment to prevent contamination of optical endfaces. Inspect and, if necessary, clean connectors before connection. Use appropriate cable management to minimise bending and strain, and ensure compatibility with your transceivers and ports prior to deployment.
