## Summary description

Direct attach copper (DAC) cable CBO EX-QSFP-40GE-DAC-2M provides a 40G connection with QSFP interface over a 2-meter passive copper link. Designed for short-range high-speed data interconnects between switches, routers or network appliances, it offers low latency, plug-and-play compatibility and a cost-effective solution for server racks and data center topologies.

## Long description

Direct attach copper (DAC) cable CBO EX-QSFP-40GE-DAC-2M 40G 2m is a passive copper cable with QSFP connector designed to deliver a 40 gigabit per second link over a 2-metre length. It provides a low-latency, energy-efficient connection between QSFP-enabled ports and is intended for short-range interconnects inside server racks and data centre top-of-rack or leaf-spine network topologies. The cable is pre-terminated for plug-and-play use with compatible QSFP ports and requires no additional transceivers.
Advantages
The cable offers a cost-effective, low-power alternative to optical transceivers for short distances, eliminating the need for separate SFP/QSFP transceiver modules. Its passive copper design reduces complexity and supports reliable, predictable latency and throughput for 40G links. The 2 m length provides flexibility within dense rack environments while keeping signal integrity suitable for typical data centre layouts.
Suitable for
 40G connections between switches and routers inside the same rack
 Server-to-switch links in data centre topologies
 Leaf-spine and top-of-rack network interconnects
 High-throughput, low-latency aggregation or uplink ports
Key specifications
 Nominal data rate: 40 Gbit/s
 Interface: QSFP (Quad Small Form-factor Pluggable)
 Cable type: Passive direct attach copper
 Length: 2 metres
 Typical application: Short-range rack and data centre interconnects
 Latency: Low, passive copper characteristics
 Power consumption: Lower than equivalent optical transceiver solutions (no external module power required)
How to use
Insert each QSFP connector into the corresponding QSFP port on your networking devices until the latch engages. Ensure both ends are seated firmly and verify link status via the device management interface. No additional configuration or transceiver modules are required; the cable acts as a direct physical link. For safe handling, avoid sharp bends and excessive pulling force on the cable and connectors during installation.
Usage recommendations
Use this DAC cable for short copper links up to 2 m within racks or adjacent racks to maintain optimal signal integrity. Avoid routing the cable near high-power or high-interference sources and respect the manufacturer’s minimum bend radius to prevent damage. Verify compatibility with your QSFP-enabled hardware and firmware to ensure plug-and-play operation.
