Cable DAC BlueLAN compatible BlueOptics MCP2103-X01AB, SFP+ a SFP+, pasivo, 10 Gbit/s, 2 m, negro (MCP2103-X01AB-BL)

BlueOptics SFP+ DAC Cable CBO MCP2103-X01AB Passive, 30 m, Twinax Direct Attach is a passive twinax assembly designed for short-range 10 Gbps connections. This 30 metre direct attach copper (DAC) cable connects SFP+ ports on switches, servers and storage devices where fiber cabling is unnecessary. It delivers a low-latency physical link suitable for data centre interconnects, top-of-rack deployments and intra-rack connections, offering a cost-effective alternative to active modules or optical transceivers when cable length and environment allow.

Advantages

The passive twinax construction provides minimal signal conversion overhead, resulting in low latency and reduced power consumption compared with active optical solutions. The fixed 30 m length simplifies planning for short-range topologies and eliminates the need for separate transceivers at each end, lowering total cost of ownership. The SFP+ form factor ensures compatibility with standard SFP+ ports on networking equipment that support DAC cables, while the direct-attach design reduces points of failure and eases installation in rack environments.

Suitable for

• Short-range 10 Gbps links between switches within a data centre rack or adjacent racks
• Server-to-switch and storage-to-switch connections where fiber is not required
• Top-of-rack and aggregation layer interconnects with SFP+ ports
• Environments prioritising low latency and low power consumption

Key specifications

• Data rate: 10 Gbps (SFP+ compatible)
• Connector type: SFP+ direct-attach twinax ends
• Cable type: Passive twinax copper
• Length: 30 metres
• Latency: low, due to passive copper design
• Typical use: short-range rack and intra-rack connections

How to use

Insert each SFP+ connector into the corresponding SFP+ port on the two devices to be linked, ensuring the latch engages securely. Confirm the connected devices support passive SFP+ DAC cables and configure network interfaces as required by your switch or server operating system. Monitor the link status LED on both devices to verify a successful connection. If link training or specific speed/duplex settings are required, adjust the port configuration via the device management interface.

Recommendations

Use this passive 30 m twinax cable in controlled data centre or rack environments where SFP+ DAC support is documented by the hardware vendor. Avoid installation in high-flex or outdoor runs; ensure bend radius and cable strain relief are respected during routing to maintain signal integrity. For longer distances or runs requiring isolation from electrical interference, consider active optical or fiber-based solutions.
