BlueOptics SFP-H25G-CU1.5M InfiniBand/optický kábel 2 m SFP28 čierny

The BlueOptics SFP-H25G-CU1.5M is a 2 m direct-attach cable with SFP28-compatible connectors designed for InfiniBand and high-speed fibre optic networking. Intended for male-to-male connections, this cable supports 25 Gbps class links and provides a compact, low-latency connection between switches, network interface cards and other equipment with SFP28 ports. Its black jacket and fixed length make it suitable for organized rack installations and short-reach interconnects in data centres and server rooms.

Advantages

This SFP28 cable offers high data throughput and predictable performance for short-reach connections without the need for separate transceivers, reducing component count and power consumption. The cable’s design ensures low latency and signal integrity over the 2 m length, while the robust connector housings and jacket protect against mechanical wear in typical data-centre environments. Compatibility with standard SFP28 cages simplifies deployment and replacement.

Suitable for

• Interconnects between switches and top-of-rack devices
• Direct links from servers to storage or network interface cards
• Short-reach connections in data centres and server rooms
• High-bandwidth InfiniBand and 25 Gbps Ethernet links

Key specifications

• Connector type: SFP28 male-to-male
• Length: 2 m
• Supported link rate: up to 25 Gbps class
• Cable jacket colour: black
• Application: short-reach direct-attach for InfiniBand and fibre optic networks

How to use

Insert each SFP28 connector firmly into the corresponding SFP28 port until the latch engages. Route the cable to avoid sharp bends and stress points; maintain manufacturer-recommended bend radius for optimal signal integrity. For hot-pluggable ports, connect or disconnect while observing standard data-centre grounding and ESD precautions. Ensure both ends are compatible with the host equipment’s SFP28 cages and that firmware or vendor compatibility requirements are met when applicable.

Recommendations

Use this 2 m direct-attach SFP28 cable for short-distance, high-bandwidth links where low latency and reduced power usage are priorities. Store spare cables in a dust-free environment and inspect connector housings for damage before installation.
