Product information

Description

BlueOptics Direct Attach Cable QSFP-100G-D-CAB-3M-CM is a 3 meter passive QSFP+ to QSFP+ assembly that supports 100GBASE-CR4 connectivity. Intended for short-reach, high-bandwidth interconnects, this cable provides a copper-based 100 Gbps link suitable for direct connections between switches, routers and servers in data centre top-of-rack and aggregation layers. The design focuses on low latency and power efficiency while offering a compact physical profile for dense rack environments.

Advantages

The cable delivers a cost-effective alternative to optical transceivers for short-distance connections, reducing both capital and operating expenses. Its passive design eliminates the need for electrical power in the cable itself and contributes to low latency communication. The QSFP+ form factor ensures compatibility with standard 100G ports, and the 3 m length balances reach and cable management inside racks.

Suitable for

  • Top-of-rack switch to switch connections
  • Server to switch high-speed links
  • Aggregation layer interconnects within racks or across adjacent racks
  • Short-reach 100G connectivity in data centres and enterprise networks

Key specifications

  • Connector type: QSFP+ to QSFP+
  • Data rate: 100 Gbps (100GBASE-CR4)
  • Length: 3 metres
  • Cable type: Passive copper direct attach
  • Application: Short-reach interconnects for racks and equipment bays
  • Physical profile: Compact, suitable for high-density rack environments

How to use

Install the QSFP-100G-D-CAB-3M-CM by inserting each QSFP+ connector into compatible 100G ports on the equipment until the latch engages. Ensure that connected devices support passive QSFP+ direct attach cables and are configured for 100GBASE-CR4 operation. Route the cable to avoid tight bends and maintain recommended bend radius to preserve signal integrity. For best results, connect one end to the source device and the other to the destination device while both devices are powered off or follow the vendor hot-plug guidelines.

Usage recommendations

Confirm compatibility with your switch or server vendor documentation before deployment and keep cable runs within the specified 3 m length. Arrange cables to minimise strain on connectors and avoid running parallel to high-power conductors to reduce potential interference.
