Product information

Description

CBO DAC cable QSFP-40G-C3M is a 3 m passive direct-attach cable offering 40Gbps connectivity with QSFP+ connectors at both ends. Engineered for short-reach interconnects in data centre environments, the cable links switches, routers and servers without the need for optical transceivers. Its passive design provides a low-latency, high-bandwidth copper connection suitable for top-of-rack and aggregation links where a cost-efficient and power-saving 40G solution is required.

Advantages

The cable delivers 40Gbps throughput with minimal latency and reduced power consumption compared with optical modules. Its passive construction reduces component count and simplifies deployment while offering robust electrical performance for short distances. The QSFP+ connectors provide a standardised interface for high-density networking equipment, enabling plug-and-play installation and reliable signal integrity across a 3 m span.

Suitable for

  • Top-of-rack switch to switch links in data centres
  • Server to switch connections requiring 40Gbps bandwidth
  • Aggregation and spine-leaf network segments over short distances
  • Environments prioritising low power consumption and reduced heat

Key specifications

  • Connector type: QSFP+ to QSFP+
  • Data rate: 40 Gbps
  • Length: 3 metres
  • Cable type: Passive direct-attach copper
  • Intended reach: short-reach links within racks or between adjacent racks

How to use

Install the DAC cable by inserting each QSFP+ connector into the corresponding QSFP+ port on networking equipment until the latch engages. Ensure both devices support passive QSFP+ direct-attach cables and are configured for 40Gbps operation. Route the cable to avoid sharp bends and mechanical strain, maintain appropriate airflow around equipment, and verify link status via device LEDs or management interfaces after connection.

Usage recommendations

Use this passive QSFP+ DAC cable for short-distance, high-bandwidth links inside racks or between adjacent racks. Avoid extended runs beyond the specified 3 m length, protect connectors from dust when not in use, and handle the cable by the connector housings to prevent damage to contacts and latches.
