BlueOptics QSFP28 Direct Attach Cable MCP1600-C00BE30N 100GBASE-CR4 Ethernet, 30AWG, 2 m

BlueOptics QSFP28 Direct Attach Cable MCP1600-C00BE30N 100GBASE-CR4 Ethernet, 30AWG, 2 m is a passive QSFP28-to-QSFP28 copper assembly designed for short-reach 100 Gigabit Ethernet links. With 30AWG construction and a 2 m length, this DAC provides a compact, low-latency connection option for data centre rack-to-rack and intra-rack interconnects that support 100GBASE-CR4 over QSFP28 interfaces.

Advantages

This direct attach cable offers a simple, low-power alternative to optical transceivers for short-distance 100G connections. Its QSFP28 form factor ensures compatibility with equipment that accepts QSFP28 copper assemblies, while the 30AWG conductor provides a balance of flexibility and signal integrity. The passive design eliminates the need for additional power and reduces heat generation compared with active modules, making it suitable for dense rack deployments and high-throughput switching environments.

Suitable for

• Short-reach 100 Gigabit Ethernet links between switches and routers
• Rack-to-rack and intra-rack connections in data centres
• Direct server-to-switch or switch-to-switch 100G interconnects
• Environments requiring low latency and high throughput

Key specifications

• Interface: QSFP28 to QSFP28
• Supported protocol: 100GBASE-CR4 Ethernet
• Conductor gauge: 30 AWG
• Cable type: Passive direct attach copper (DAC)
• Length: 2 meters
• Use case: Short-reach, rack and chassis interconnects

How to use

Install the cable by inserting each QSFP28 connector firmly into the corresponding QSFP28 port on the network devices until the latch engages. Verify link status via the devices' interface indicators or management console. No additional configuration is typically required beyond ensuring both endpoints support 100GBASE-CR4 over QSFP28. For removal, depress the connector latch and withdraw the plug evenly to avoid stressing the cable or ports.

Usage recommendations

Route the cable with gentle bends, avoiding tight radii and excessive force; maintain proper airflow in racks by organizing DACs to prevent blocking ventilation. Use this passive 2 m QSFP28 DAC for short-distance connections where power consumption and latency are critical factors. Confirm compatibility with your networking equipment documentation before deployment.
