Cable de fibra óptica InfiniBand BlueOptics SFP-25G-50CM-NV-BL 0,5 m SFP28 conector/conector

The BlueOptics SFP-25G-50CM-NV-BL InfiniBand fibre optic cable 0.5 m SFP28 Male/Male is a short-reach direct attach solution designed for high-speed connections between rack-mounted devices. With SFP28 connectors on both ends and a 0.5 m length, the cable supports up to 25 Gbps data rates and is intended for use where a compact, reliable link is required for switches, routers, storage systems and other compatible networking hardware.

Advantages

This SFP28 to SFP28 direct attach cable provides a passive, low-latency connection for short-distance links. It is MSA-compliant and manufactured to meet established interface standards, ensuring physical compatibility with devices that support SFP28 InfiniBand or 25GBase-CR connections. The cable’s compact 0.5 m length simplifies rack cabling and reduces clutter while delivering consistent signal transmission suitable for Ethernet, Fibre Channel, FCoE and InfiniBand applications up to 25 Gbps when used within supported platforms.

Suitable for

• Short interconnects between adjacent rack units and within server racks
• High-speed links for switches, routers and storage arrays that accept SFP28 ports
• Data centre top-of-rack and server-to-switch connections requiring 25 Gbps

Key specifications

• Connector type: SFP28 male to SFP28 male
• Length: 0.5 meter
• Maximum supported data rate: up to 25 Gbps
• Cable type: direct attach (twinax passive copper electrical connection for short distances)
• Compliance: MSA-compliant interface

How to use

Install the BlueOptics SFP-25G-50CM-NV-BL by inserting each SFP28 connector into the corresponding SFP28 port on the two devices to be linked, ensuring the connectors latch securely. Verify that the hardware and firmware of both endpoints support passive direct attach SFP28 connections at 25 Gbps. No external power or additional transceivers are required for passive operation; configuration and link negotiation are handled by the connected equipment according to the supported protocol (Ethernet, Fibre Channel, FCoE or InfiniBand).

Recommendations

Use this 0.5 m passive SFP28 direct attach cable for short, point-to-point connections inside racks or between adjacent racks. Confirm device compatibility and firmware support for passive DAC operation before deployment. Avoid tight bends and protect connectors from contamination to maintain signal integrity and prolong service life.
