DAC Cable CBO QSFP28 SC282801L1M30 1 m shielded direct-attach copper cable for 100GbE

CBO DAC Cable QSFP28 SC282801L1M30 is a 1 meter shielded direct-attach copper cable engineered for QSFP28 interfaces and 100GbE links. The cable provides a short-reach, low-latency physical connection between compatible ports on switches, routers and network adapters without requiring optical transceivers. Its shielded construction reduces electromagnetic interference and supports reliable high-speed data transmission in dense rack environments and data center topologies.

Advantages

The shielded direct-attach design offers lower latency and reduced power consumption compared with optical modules and active cable solutions. A one-meter fixed-length assembly simplifies rack cabling and ensures predictable channel characteristics. Compatibility with QSFP28 ports enables straightforward use for 100 gigabit Ethernet interconnects, while the ruggedized connectors and braided shielding provide mechanical stability and signal integrity for short-reach links.

Suitable for

• 100GbE connections between switches in data center aggregation and spine-leaf topologies
• Direct server-to-switch or server-to-router links in rack-mounted systems
• Short-reach interconnects in high-density network racks where optical transceivers are not required

Key specifications

• Interface type: QSFP28 to QSFP28
• Length: 1 meter
• Cable type: Shielded direct-attach copper (DAC)
• Supported data rate: 100 Gigabit Ethernet
• Latency: Low-latency passive copper link for short-reach applications
• Construction: Braided shield with robust connector housings for rack use

How to use

Install the cable by plugging each QSFP28 connector into the corresponding QSFP28 port on your network devices. Ensure devices are powered down or that hot-plug procedures recommended by the device manufacturer are followed. Verify the link status through device LEDs or management interfaces and confirm that ports are configured for 100GbE operation. Avoid sharp bends and maintain the minimum bend radius specified by the equipment manufacturer to preserve signal integrity.

Recommendations

Use this 1 m shielded DAC cable for short, direct connections inside racks and between adjacent units; for longer distances or where optical isolation is needed, select an appropriate optical transceiver solution. Store and route the cable to prevent kinks and excessive strain on connectors.
