InfiniBand/fibre optic cable BlueOptics SP-CABLE-FS-SFP+3-BL 3 m Male/Male

The BlueOptics SP-CABLE-FS-SFP+3-BL is a 3 m InfiniBand/fibre optic cable with SFP+ male-to-male connectors designed for short-reach, high-speed network links. It supports 10G-class connections and is intended for direct attachment between compatible SFP+ ports in racks, adjacent racks or network devices. The cable is manufactured to comply with common MSA specifications and is suitable for environments where reliable, low-latency data transmission is required.

Advantages

This 3 m SFP+ cable provides a cost-effective direct attach solution with low power consumption and reduced latency compared to active optical modules. The male-to-male SFP+ ends ensure straightforward plug-and-play connectivity between compatible SFP+ ports. Manufactured using industry-standard components and tested for compatibility, the cable offers robust mechanical quality and a long service life for data centre and enterprise networking use.

Suitable for

• Interconnecting switches, routers and storage systems within server racks
• Short-reach 10G Ethernet, FCoE or InfiniBand links up to 3 m
• High-density rack installations and adjacent-rack connections

Key specifications

• Cable length: 3 m
• Connector type: SFP+ male to SFP+ male
• Supported data rates: up to 10 Gbit/s
• Cable type: direct attach (twinax / short-reach copper or passive direct attach twinax as applicable)
• Transmission: electrical 10GBase-CR and compatible protocols (Ethernet, FCoE, InfiniBand)
• Wire gauge: 30 AWG (typical for 10G twinax DAC)
• Designed for short-distance, rack-to-rack or intra-rack connections

How to use

Verify that both network devices support passive SFP+ direct attach cables and that the SFP+ ports accept third-party cables. With devices powered down or following hot-plug guidelines from the equipment manufacturer, insert each SFP+ connector into the corresponding port until it latches. Confirm link status through device LEDs or management interfaces and configure the network interfaces for the desired protocol and speed. For removal, release the latch and pull the module straight out to avoid strain on the connector.

Recommendations

Use this cable for short-distance 10G connections within racks or between adjacent racks. Avoid tight bends and excessive mechanical stress, and follow the host equipment vendor guidelines regarding third-party passive DAC compatibility. For longer runs or active optical requirements, consider appropriate fibre-optic transceivers or active cables.
