Product information

Description

CBO DAC Cable QSFP28 Compatible CAB-Q28-Q28-50CM-BL is a 50 cm direct attach copper (DAC) cable engineered for short-range, high-bandwidth interconnects between QSFP28-equipped devices. The passive copper assembly connects QSFP28 ports on switches, routers and servers to provide a low-latency physical link suitable for 100 Gigabit Ethernet and other QSFP28 applications in data center and rack-to-rack environments.

Advantages

The cable offers a simple, plug-and-play solution with low insertion loss and predictable electrical performance over the specified 50 cm reach. Passive construction eliminates the need for separate transceivers, reducing total hardware cost and simplifying inventory. Its QSFP28-compatible connectors are designed for secure mating and consistent signal integrity in dense networking racks.

Suitable for

  • Short-distance 100GbE connections between servers and switches
  • High-density rack-to-rack links in data centers
  • Connecting QSFP28 ports for low-latency applications such as storage networks and virtualization hosts
  • Temporary or permanent cabling in lab and test environments

Key specifications

  • Form factor: QSFP28 to QSFP28 direct attach copper cable
  • Length: 50 cm
  • Cable type: Passive copper twinax assembly
  • Data rate support: Suitable for 100 Gigabit Ethernet and other QSFP28-compatible protocols
  • Connector compatibility: QSFP28 ports on networking equipment
  • Application environment: Short-reach data center and rack-to-rack connections

How to use

Install the cable by aligning each QSFP28 plug with the corresponding port and inserting until the connector latches. No additional transceivers or configuration are required for most systems; the host devices should recognize the direct attach connection automatically. Ensure both ends are fully seated and that the cable routing avoids sharp bends or crushing to maintain signal integrity. For removal, depress the latch on the module and withdraw the connector evenly.

Usage recommendations

Verify QSFP28 port compatibility and firmware support on both devices before deployment. Use the 50 cm length for short interconnections within the same rack or adjacent racks to maintain specified signal performance. Avoid excessive bending radius and mechanical stress on the cable; maintain a clean environment to prevent dust accumulation on connector interfaces.
