DAC SFP+ passive direct attach cable CBO MCP2102-X001B 30m

The DAC SFP+ passive direct attach cable CBO MCP2102-X001B 30m is a 30‑metre copper interconnect designed for SFP+ ports on switches, servers and network interface cards. It supports 10 Gbps-class short-range links and provides a low-latency, wired connection where passive direct attach copper is supported by the devices. The cable is intended for point‑to‑point connections inside racks or between adjacent equipment in data center and enterprise network environments.

Advantages

The cable delivers a cost-effective alternative to active optical solutions for short distances, with minimal signal conversion and reduced power consumption since no transceiver electronics are required in the cable itself. Its passive design offers low latency and predictable electrical performance for 10 Gbps data rates. The 30 m length enables flexible placement of equipment across adjacent racks or within larger cabinet rows while maintaining a single-cable solution for SFP+ ports.

Suitable for

• 10 Gbps SFP+ connections between switches and servers in data centers
• Direct links between network interface cards (NICs) and top‑of‑rack switches
• Short-range copper connections inside cabinets or between adjacent racks
• Environments where passive DACs are supported and optical transceivers are unnecessary

Key specifications

• Connector type: SFP+ compatible copper direct attach
• Data rate: up to 10 Gbps
• Length: 30 metres
• Cable type: passive twinaxial copper
• Typical use: short-reach, point-to-point interconnects

How to use

Install the DAC SFP+ cable by inserting each SFP+ plug into the corresponding SFP+ port on the network devices until the latch engages. Ensure both devices support passive SFP+ direct attach copper and are powered down or in maintenance mode if hot‑plugging policies require it. After insertion, verify link status and speed on the devices' management interfaces; the connection should present as a 10 Gbps link if both ends negotiate the same speed. Avoid tight bends and secure the cable to prevent strain on connectors.

Recommendations

Use this passive DAC for intra-rack and adjacent-rack connections where 30 m of copper reach is sufficient and devices explicitly support passive SFP+ direct attach. Do not use this cable for longer distances, for environments requiring fiber optics, or with devices that only support active or optical transceivers. Maintain proper cable routing and avoid exposure to excessive heat or mechanical stress to preserve signal integrity.
