Product information

Description

The BlueOptics 470-ABOS-BL is a 2-meter direct attach cable (DAC) with a QSFP28 connector on one end and four SFP28 connectors on the other. Designed for short-reach, high-speed connections in data centers and rack environments, this passive twinax copper cable supports aggregated 100G transmission (4x25G) when used with compatible hardware that accepts passive QSFP28-to-4xSFP28 modules. The cable is finished in black and is intended for in-rack or adjacent-rack links where low latency and low power consumption are required.

Advantages

The cable offers a straightforward, low-latency connection method without active components, reducing power draw and points of failure. Built to MSA-aligned specifications, it provides predictable electrical characteristics for reliable signal integrity in supported hardware. Its passive twinax design results in low power consumption and a simple physical interface that is easy to deploy in dense rack installations.

Suitable for

  • Short-range interconnects between switches within the same rack or neighboring racks
  • High-density top-of-rack aggregation using QSFP28 to 4xSFP28 ports
  • Connections between switches, routers, and storage systems that accept passive DACs
  • Environments where low latency and low power usage are priorities

Key specifications

  • Length: 2 meters
  • Connector types: QSFP28 (one end) to 4 × SFP28 (other end)
  • Transmission: passive twinax copper for up to 100G aggregated (4 × 25G) over short distances
  • Design: black cable jacket; lightweight construction (approx. 0.25 kg)
  • Form factor: Direct Attach Cable (DAC), compliant with MSA electrical and mechanical guidelines
  • Typical use: rack-to-rack or in-rack high-speed links with compatible hardware

How to use

Install the cable by inserting the QSFP28 plug into the host device QSFP28 port and the four SFP28 plugs into the corresponding SFP28 ports on the target device, observing port orientation and handling precautions. Ensure both devices support passive QSFP28-to-4xSFP28 DAC connections and that link settings (speed, auto-negotiation) match the intended configuration. Handle connectors by their housings, avoid excessive bending near the terminations, and route the cable to minimize strain and electromagnetic interference.

Usage recommendations

For reliable operation, verify compatibility with network equipment vendor documentation and firmware versions before deployment. Use this passive DAC for short-distance links inside racks or between adjacent racks; for longer runs choose optical transceivers or active solutions. Store and install the cable in temperatures and environments specified by your hardware supplier, and perform link tests after installation to confirm expected throughput and error-free operation.
