BlueOptics MCP1600-C002E26N 100GBASE-CR4 Direct Attach Cable, 30AWG, 2 m

BlueOptics MCP1600-C002E26N 100GBASE-CR4 Direct Attach Cable, 30AWG, 2 m is a short-range copper twinax assembly engineered for 100 Gbps Ethernet links. With a 2-meter length and 30AWG conductors, this DAC provides a low-latency, low-power physical connection for high-density environments. It implements the 100GBASE-CR4 interface to deliver full-rate 100 Gbps signalling over direct attach copper between compatible ports, making it suitable for top-of-rack and aggregation-layer cabling in data centers and high-performance racks.

Advantages

The cable offers a simple, passive connection that eliminates the need for transceivers, reducing both cost and power consumption compared with optical modules. Its 30AWG construction balances flexibility and signal integrity for short links while the 2 m length supports typical rack-to-rack or server-to-switch layouts. The direct attach design yields minimal insertion loss and predictable latency, which is beneficial for latency-sensitive applications and dense switch deployments.

Suitable for

• Server-to-switch connections in data center racks
• Switch-to-switch interconnects within the same equipment room or rack
• High-throughput compute clusters and storage fabrics requiring 100 Gbps links
• Network consolidation where low-latency, short-reach links are needed

Key specifications

• Standard: 100GBASE-CR4 (100 Gbps over copper)
• Length: 2 m
• Conductor gauge: 30AWG twinax
• Connector type: Direct Attach Copper (fixed twinax plugs compatible with 100G CR4 ports)
• Use case: Short-reach, rack/room-level interconnects
• Latency: low, passive direct attach connection

How to use

Install the DAC by inserting each plug into the corresponding 100GBASE-CR4 compatible port until the connector latches securely. Ensure both network devices support 100GBASE-CR4 over direct attach copper and that firmware/port settings are configured for 100 Gbps operation. Route the cable to avoid sharp bends and mechanical stress; maintain recommended bend radii and secure the cable within the rack to prevent strain on the connectors. For multi-port deployments, label connections to simplify maintenance and troubleshooting.

Usage recommendations

Verify compatibility with the switch and server vendor's list of supported direct attach cables before deployment. Use the 2 m length for intra-rack or adjacent-rack connections; for longer distances, consider optical transceivers and fiber cabling. Inspect connectors for debris before insertion and avoid repeated unplugging to prolong connector life.
