Product information

Description

The BlueOptics 498385-B21-BL is a 1 m InfiniBand/fibre optic direct attach cable with QSFP male connectors on both ends. Designed for short-reach, high-speed links in data centers and rack environments, this cable supports 40GBase-CR4 electrical transmission and is appropriate for Ethernet, FCoE, Fibre Channel and InfiniBand applications up to 40 Gbps over a 1 metre distance. The product follows MSA-compliant design and is built with quality components to ensure reliable connectivity between switches, routers, storage systems and other compatible hardware.

Advantages

This 1 m QSFP-to-QSFP cable provides a low-latency, low-power direct attach solution for short interconnects where active transceivers are not required. As a passive twinax direct attach cable, it reduces system power consumption and simplifies installation by offering plug-and-play connectivity. The construction uses industry-standard components and manufacturing practices to deliver consistent performance, long service life and compatibility with platforms that support 40GBase-CR4 DACs.

Suitable for

  • Short-distance high-speed rack-to-rack and intra-rack connections
  • Switch-to-switch, switch-to-server and switch-to-storage links
  • Data center top-of-rack and aggregation layer interconnects
  • Environments using Ethernet, FCoE, Fibre Channel or InfiniBand at 40 Gbps

Key specifications

  • Connector type: QSFP male to QSFP male
  • Length: 1 metre
  • Data rate support: up to 40 Gbps per cable (40GBase-CR4)
  • Cable type: passive twinax copper direct attach
  • Wire gauge: 30 AWG
  • Standards: MSA-compliant design for QSFP DAC applications
  • Typical use: short-reach rack and adjacent-rack interconnects

How to use

Ensure both endpoints support passive QSFP direct attach cables and the 40GBase-CR4 transmission protocol. With network equipment powered off or in a safe maintenance state, align each QSFP connector with the corresponding port and insert until the latch engages. After installation, power on the devices and verify link status and negotiated speed in the management interface or LED indicators. For removal, disengage the latch and pull the connector straight out to avoid stress on the port or cable.

Usage recommendations

Use this cable for short-distance connections within racks or between adjacent racks only; avoid running it through long cable trays or across long paths. Maintain bend radii recommended by the hardware manufacturer and avoid crushing or kinking the cable. Confirm compatibility with the specific hardware model and firmware version for guaranteed passive DAC operation.
