BlueOptics Direct Attach Cable MCP1600-E01BE30-BL — 1 m, 100GBASE-CR4, Infiniband EDR, 30AWG

BlueOptics MCP1600-E01BE30-BL is a 1 m direct attach copper (DAC) cable engineered for short-reach, high-speed links. It is designed to support 100GBASE-CR4 Ethernet and Infiniband EDR interconnects, offering a compact, low-latency physical connection for switches, servers and network interface cards in dense networking environments. The cable’s 30AWG construction balances flexibility and signal integrity for reliable performance in racks and top-of-rack deployments.

Advantages

This 1 m direct attach cable provides a cost-effective alternative to optical modules for short-distance connections, with low power consumption and minimal added latency. The 30AWG design enables compact routing in high-density installations while maintaining adequate shielding and pair geometry for 100GBASE-CR4 and EDR signalling. Its fixed-length copper assembly simplifies installation and reduces component inventory compared with pluggable transceivers and separate fiber assemblies.

Suitable for

• Short-reach 100 Gigabit Ethernet links within racks or between adjacent racks
• Infiniband EDR interconnects for high-performance compute nodes
• Top-of-rack (ToR) switch connections to servers and NICs
• High-density networking environments where fixed 1 m cables reduce cable management complexity

Key specifications

• Length: 1 meter
• Supported protocol: 100GBASE-CR4 Ethernet
• Compatible interconnect: Infiniband EDR
• Conductor gauge: 30 AWG
• Cable type: Direct attach copper (DAC), twinax assembly
• Use case: Short-reach, high-speed server and switch connections

How to use

Connect each end of the direct attach cable to the corresponding 100G-capable ports on switches, servers or NICs, ensuring secure mating and proper orientation. Route the cable within the rack to avoid sharp bends and excessive tension; follow equipment vendor guidelines for bend radius. For best results, verify link status and negotiated speed on both endpoints after insertion and perform any required firmware or driver checks on connected devices.

Usage recommendations

Use this 1 m DAC for short, fixed connections where 100GBASE-CR4 or Infiniband EDR is supported by both endpoints. Avoid running the cable near sources of high electromagnetic interference and do not exceed recommended bend radii. Replace the cable if connectors show physical damage or if link errors persist after troubleshooting.
