## Summary description

Direct attach copper QSFP cable by BlueOptics, model 10093084-2010LF, supporting 40GBASE-CR4 connectivity over a 1-meter length. Designed for short-range high-speed links between QSFP ports in data centers and network equipment, it provides native 40 Gigabit Ethernet passive copper connectivity for server-to-switch, switch-to-switch, and appliance interconnects.

## Long description

BlueOptics Copper QSFP Direct Attach Cable 40GBASE-CR4, 1 m is a passive copper interconnect designed for short-range 40 Gigabit Ethernet links. The cable provides a native QSFP-to-QSFP connection over a 1 metre length, enabling high-bandwidth, low-latency links between servers, switches and network appliances in data centre racks and top-of-rack deployments. It supports the 40GBASE-CR4 standard for short-reach direct-attach copper connections and is intended for use where optical transceivers are not required.
Advantages
This 40GBASE-CR4 copper direct attach cable delivers low-latency, native 40 Gbps connectivity without the need for active optical components. Its passive construction reduces power consumption compared with active cables and optics, and the 1 m length minimises signal loss for short interconnects. The QSFP form-factor plugs provide straightforward, tool-free installation into compatible QSFP ports and ensure secure mechanical connection. The cable is suitable for dense rack environments where predictable, high-bandwidth links are required between nearby devices.
Suitable for
 Server-to-switch connections in data centre racks
 Switch-to-switch short-reach interconnects within the same rack or adjacent racks
 Connecting network appliances and high-performance compute nodes
Key specifications
 Interface: QSFP to QSFP
 Standard: 40GBASE-CR4 (40 Gigabit Ethernet over copper)
 Cable type: Passive copper direct attach
 Length: 1 m
 Data rate: 40 Gbps aggregate
 Form factor: QSFP connector housing
How to use
Verify that both devices have compatible QSFP ports supporting 40GBASE-CR4 before installation. Align the QSFP connectors with the equipment ports and insert until the retention mechanism engages; do not force the connector. For removal, release the connector latch or pull-tab and extract the plug straight out to avoid damaging the port. Use the cable for short, direct interconnects inside racks or between adjacent racks; avoid routing the cable near sharp edges or tight bends that could damage the copper conductors.
Usage recommendations
For reliable performance, maintain the minimum bend radius specified by the manufacturer, keep cable length to the intended 1 m distance for optimal signal integrity, and use in temperature-controlled data centre environments. Ensure firmware and port settings on connected equipment are configured for 40G operation and confirm compatibility with passive QSFP copper assemblies in your switching and server hardware.
