Product information

Description

BlueOptics MCP21J2-X02AA is a 3 m copper SFP+ direct attach cable (DAC) designed for short-range 10 Gigabit Ethernet links. The cable is terminated with SFP+ form-factor connectors and implements 10GBASE-CR electrical signalling over twinax copper, offering a compact and low-latency connection option for servers, switches and storage appliances in rack and data centre environments.

Advantages

This 3 m copper DAC delivers predictable electrical performance with reduced power consumption compared with active optical solutions. The passive SFP+ cable provides low latency and high throughput for 10GBASE-CR links, and its fixed length and integrated connectors simplify installation and reduce the need for additional transceivers or patch cords. The rugged twinax construction and SFP+ form factor ensure reliable mating with compatible SFP+ ports and stable signal integrity across short distances.

Suitable for

  • Short-reach 10 Gigabit Ethernet links between top-of-rack switches and servers
  • Direct connections between network switches for uplinks and stacking
  • Storage area networks and server-to-storage links in rack-mount systems
  • High-density data centre environments where low latency is required

Key specifications

  • Form factor: SFP+ to SFP+ direct attach cable (twinax)
  • Media type: Copper twinax
  • Nominal length: 3 metres
  • Data rate: 10 Gigabit Ethernet (10GBASE-CR)
  • Connector compatibility: SFP+ ports (compatible with standard SFP+ cages)
  • Latency: Passive cable with minimal added latency suitable for short-range links
  • Typical use environment: Rack-mounted equipment and data centre interconnects

How to use

Insert each SFP+ connector into the corresponding SFP+ port on the network devices until the latch engages. Ensure that connected devices are powered and properly configured for 10G operation. Because this is a passive direct attach cable, no separate transceiver modules or optical equipment are required. Verify link status and speed on both ends using device management interfaces and network monitoring tools.

Usage recommendations

Use the cable for short-distance interconnects within the same rack or adjacent racks. Avoid sharp bends and excessive pulling on the cable; maintain bend radius recommended by the equipment vendor. Confirm compatibility with your device vendor's SFP+ port implementation and verify link negotiation settings to ensure stable 10GBASE-CR operation.
