Cavo in fibra ottica InfiniBand BlueOptics CAB-S-S-25G-2M-BL 2 m SFP28 connettore/connettore

The BlueOptics CAB-S-S-25G-2M-BL is a 2-meter SFP28-to-SFP28 direct attach cable designed for high-speed InfiniBand and 25GBase-CR applications. It is intended for short-distance electrical connections between compatible network devices in rack and adjacent-rack installations, providing a male-to-male SFP28 interface for direct link-up of switches, routers, storage systems and other hardware that supports SFP28 passive twinax or compatible 25G DAC solutions.

Advantages

This 2m cable offers a compact, low-latency connection for 25 Gbps links with a simple passive design that requires no additional power. The cable follows industry MSA-compatible form factors and is manufactured using standard high-quality components to ensure stable signal transmission and reliable mechanical fit with SFP28 ports. Its short length and direct attach format reduce cabling complexity in dense rack environments while delivering consistent performance for supported protocols.

Suitable for

• Short‑reach connections between rack-mounted switches and adjacent racks
• Direct links for 25GBase‑CR, Ethernet and InfiniBand-capable equipment
• High-density server or storage interconnects where SFP28 ports are available

Key specifications

• Connector type: SFP28 male to SFP28 male
• Length: 2 meters
• Data rate support: up to 25 Gbps
• Cable type: direct attach (twinax/compatible passive DAC)
• Typical use: short-distance electrical transmission between compatible devices

How to use

Install the cable by inserting each SFP28 connector into the corresponding SFP28 port on the devices to be linked, ensuring the latch engages and the connectors are fully seated. Verify that both devices support passive 25G DAC-style SFP28 connections and configure interfaces according to the device vendor’s instructions. No external power or transceivers are required when used in hardware platforms that allow passive direct attach cables.

Recommendations

Confirm compatibility with your equipment vendor’s supported cable list before deployment and avoid sharp bends or excessive strain on the cable; maintain minimum bend radius recommended for twinax/direct attach cables to preserve signal integrity and cable life.
