DAC-kabel CBO 100G QSFP28 3m voor Dell Networking 17CWJ-BL

The BlueOptics DAC Cable CBO 100G QSFP28 3m for Dell Networking 17CWJ-BL is a direct attach copper solution for short-reach 100 Gigabit links. This 3-meter QSFP28 copper cable provides a point-to-point connection between QSFP28 ports on switches, routers or servers and is compatible with Dell Networking equipment. It eliminates the need for separate optical transceivers by integrating the copper assembly into a single plug-and-play cable, offering a compact, low-latency interconnect for dense rack environments.

Advantages

This DAC cable delivers low latency and reduced power consumption compared with equivalent optical links, and the fixed-cable design simplifies rack cabling and port management. The QSFP28 interface supports 100G signaling over a 3 m copper reach suited to top-of-rack and adjacent-rack connections. Compatibility with Dell Networking QSFP28 ports enables simple installation without additional module purchases or configuration steps.

Suitable for (tasks / use cases)

• Top-of-rack switch-to-switch 100G connections
• Server-to-switch high-speed interconnects within a rack
• Interconnects between adjacent racks in data center pods
• Short-reach links in high-density switching environments

Key specifications

• Connector type: QSFP28 to QSFP28 copper direct attach
• Data rate: 100 Gbps
• Cable length: 3 meters
• Media: passive copper assembly suitable for short-reach applications
• Compatibility: designed for use with Dell Networking QSFP28 ports and similar QSFP28 interfaces
• Form factor: fixed twinax DAC with integrated connectors

How to use

Power down is not required in most modern switch and server environments; align the QSFP28 connectors with the device ports and insert until the latch engages. Ensure both ends are seated firmly and the cable follows a clean path within the rack to avoid excessive bend radius or mechanical strain. For removal, depress the latch and withdraw the connector straight out to avoid damaging the port or cable assembly. Verify link status in the device management interface after insertion.

Recommendations

Use this DAC cable for short, direct 100G links where low latency and low power are priorities. Avoid routing the cable near heat sources or sharp edges, and maintain manufacturer-recommended bend radius. For runs beyond short-reach copper limits or where optical isolation is required, consider fiber-based alternatives.
