CBO DAC Cable MCP1600-C02AE30L 100G QSFP28, direct-attach copper, 3 m

The CBO DAC Cable MCP1600-C02AE30L 100G QSFP28 is a 3 meter passive direct‑attach copper (DAC) cable designed for short‑range, high‑speed connections. It provides a ready‑to‑use copper link capable of 100 Gigabit Ethernet when used with compatible QSFP28 ports, eliminating the need for separate optical transceivers. The cable is intended for data centre top‑of‑rack, server‑to‑switch and device‑to‑device interconnects where low latency and cost efficiency are priorities.

Advantages

This direct‑attach copper cable offers plug‑and‑play installation with no additional transceiver modules required, reducing overall deployment cost and complexity. Its passive QSFP28 design supports 100G connections over a 3 m reach, providing a low‑latency physical link suitable for dense rack environments. The fixed copper assembly simplifies inventory and replacement compared with separate optical transceivers and fibre patch cords.

Suitable for

• Top‑of‑rack switch to server connections in data centres
• Server‑to‑switch and switch‑to‑switch short‑reach links
• High‑performance network adapters and storage device interconnects
• Environments where low latency and cost‑effective 100G links are required

Key specifications

• Connector type: QSFP28 to QSFP28
• Nominal data rate: 100 Gigabit Ethernet
• Cable type: Passive direct‑attach copper (DAC)
• Length: 3 m
• Typical use: Short‑reach, high‑speed rack and server interconnects

How to use

Install the cable by inserting each QSFP28 connector into the corresponding port on the devices to be connected, ensuring proper latch engagement. No transceiver modules are required; the cable establishes the electrical 100G link when both endpoints support QSFP28 DAC connections. Verify link status and speed in the host or switch management interface after plugging in, and replace the cable if connector damage or degraded performance is observed.

Recommendations

For reliable operation, use this passive DAC cable within rack or short‑span pathways and avoid tight bends or excessive pulling on the cable. Confirm compatibility with device QSFP28 ports and firmware requirements before deployment, and maintain a clean environment to prevent connector contamination.
