InfiniBand/fibre optic cable SFP+ BlueOptics CB-DASFP-2M-BL 2m Male/Male

The BlueOptics CB-DASFP-2M-BL is a 2-meter Direct Attach Cable (DAC) with SFP+ connectors on both ends in a male/male configuration. Designed for short-reach high-speed connections, this passive 10GBase-CR twinax copper cable supports up to 10 Gbit/s data rates and complies with SFP+ / MSA physical and electrical specifications. The cable is intended for linking devices in racks and between adjacent racks where a reliable, low-latency 10G connection is required.

Advantages

This 2 m SFP+ cable provides a cost-effective and power-efficient alternative to active optical modules for short distances, with very low latency and minimal power consumption. The passive twinax construction offers simple, robust connectivity with a low failure rate and consistent performance for Ethernet, FCoE and InfiniBand applications up to 10 Gbit/s. Manufactured to industry MSA guidelines, the cable is compatible with hardware platforms that accept standard SFP+ DAC connections.

Suitable for

• Interconnecting switches, routers and servers within racks
• Short-distance links between adjacent rack units in data centres
• 10G Ethernet, Fibre Channel over Ethernet (FCoE) and InfiniBand up to 10 Gbit/s
• Storage systems and top-of-rack networking deployments

Key specifications

• Connector type: SFP+ male to SFP+ male
• Cable type: Passive twinax copper (Direct Attach Cable)
• Length: 2 meters
• Maximum data rate: up to 10 Gbit/s
• Wire gauge: 30 AWG (typical for twinax DAC)
• Compliance: SFP+ / MSA electrical and mechanical specifications
• Typical use: short-reach rack-to-rack and intra-rack connections

How to use

Ensure both devices support passive SFP+ DAC connections and that the relevant SFP+ ports are powered down if required by your equipment procedure. Align the SFP+ connectors and insert each end into the corresponding SFP+ port until the retention latch engages. After installation, verify the link lights and check the device interface status to confirm a successful 10G connection. For removal, depress the retention latch and pull the connector straight out to avoid stressing the cable or host port.

Recommendations

Use the BlueOptics 2 m SFP+ DAC for short-distance, high-throughput interconnects where passive twinax cabling is supported. Avoid routing the cable near strong electromagnetic sources and do not bend the cable sharply; maintain manufacturer-recommended bend radii. For best results, match cable length to the required distance to minimise slack and ensure proper airflow in rack environments.
