SFP+ Cable BlueOptics SFP-10G-CU1M-BL 1m Male/Male Black

The BlueOptics SFP-10G-CU1M-BL is a 1 meter SFP+ direct attach cable (DAC) with SFP+ male connectors on both ends, designed for short-distance, high-speed 10G interconnects. This passive twinax copper cable follows MSA-compliant SFP+ form-factor conventions and is suitable for linking switches, routers, storage systems and other network hardware that accept SFP+ direct attach copper assemblies. The cable is manufactured as a 30 AWG twinax type and is intended for electrical 10GBase-CR connections over a 1 m distance, offering low latency and low power consumption characteristic of passive DACs.

Advantages

The cable provides a reliable and cost-effective 10 Gbps connection for rack-to-rack and intra-rack links without requiring additional transceivers or active electronics. Being passive, it consumes negligible power and introduces minimal latency. Construction with high-quality components and compliance with MSA standards supports broad compatibility with major hardware platforms. The compact 1 m length reduces clutter in dense rack environments while the black jacket and robust connectors improve physical durability.

Suitable for

• Short-distance 10 Gbps links between switches and routers in data centers
• Direct connections between servers and storage arrays within racks
• Patch connections across adjacent racks or equipment shelves
• Environments that require low-latency, low-power copper interconnects

Key specifications

• Form factor: SFP+ to SFP+ direct attach cable (DAC)
• Length: 1 meter
• Data rate: up to 10 Gbps (10GBase-CR)
• Cable type: passive twinax copper, 30 AWG
• Power consumption: passive (negligible, ~0.1 W typical for passive DAC solutions)
• Colour: black
• Weight: approximately 0.08 kg

How to use

Insert each SFP+ connector into the corresponding SFP+ port on the network devices until the latch engages. Ensure that both devices support passive 10G DAC connections and the 10GBase-CR transmission protocol. After insertion, verify link status through the devices' management interface or LEDs. For removal, depress the retention mechanism and gently withdraw the connector to avoid damage to the port or cable.

Recommendations

Use this 1 m passive SFP+ DAC for short-range connections inside racks or between adjacent racks. Confirm firmware and hardware compatibility with the target switches, routers or storage systems before deployment. Avoid sharp bends and excessive tension on the cable; maintain a bend radius consistent with twinax construction to preserve signal integrity and prolong service life.
