Cable SFP+ BlueOptics SFP-10G-CU3M-BL 3 m conector macho/conector macho negro plata

The BlueOptics SFP-10G-CU3M-BL is a 3‑meter passive SFP+ direct attach copper (DAC) cable with SFP+ male connectors on both ends, designed for short‑reach high‑speed links in racks and between adjacent racks. It supports 10GBase‑CR electrical signalling and is intended for 10 Gigabit Ethernet, FCoE and InfiniBand applications where a cost‑effective, low‑latency copper connection is required. The cable uses 30 AWG twinax construction and follows MSA guidelines to ensure physical and electrical compatibility with hardware that supports SFP+ DAC modules.

Advantages

This SFP+ cable provides a reliable, low‑latency connection for short distances with very low power consumption because it is a passive DAC. Manufactured using high‑quality components compliant with MSA specifications, it offers stable performance in switch, router and storage environments. The fixed 3 m length and SFP+ male‑to‑male connectors simplify installation in rack setups and reduce the need for separate transceivers, delivering a cost‑effective alternative to optical modules for supported devices.

Suitable for

• Interconnecting SFP+ ports in top‑of‑rack and adjacent rack switches
• Server to switch and storage to switch connections at 10 Gbps
• Short‑reach 10GBase‑CR, FCoE and InfiniBand links within data centers

Key specifications

• Connector type: SFP+ male to SFP+ male
• Length: 3 meters
• Transmission: passive twinax copper (DAC)
• Supported data rate: up to 10 Gbit/s
• Wire gauge: 30 AWG twinax
• Protocol support: 10GBase‑CR, FCoE, Fibre Channel, InfiniBand (up to 10 Gbit/s)
• Compliance: MSA‑compliant physical and electrical characteristics
• Typical applications: short‑distance rack and adjacent rack interconnects

How to use

Verify that both devices support passive SFP+ DAC cables and that the SFP+ ports are enabled. Insert each SFP+ connector firmly into the corresponding SFP+ port on the devices until the latch engages. Route the cable to avoid sharp bends and strain on the connectors; maintain the recommended bend radius for twinax cables. After physical connection, check the link status on the devices and configure the network interfaces according to your network policy and protocol requirements.

Recommendations

Use this 3 m passive SFP+ DAC primarily for short rack‑level connections. Avoid using it for distances beyond the specified 3 m, ensure device firmware and compatibility settings allow passive DAC operation, and handle connectors carefully to preserve contact integrity and ensure long service life.
