## Summary description

CBO LSWM1QSTK05 is a 0.5 m QSFP Direct Attach (DAC) cable for short-range high-speed connections between QSFP ports. As a passive copper assembly, it provides low-latency, low-power links for switches, servers and storage in data centers and rack deployments. Use it for reliable 40Gb/100Gb-class interconnects where a short, fixed-length cable is needed.

## Long description

CBO LSWM1QSTK05 is a 0.5 m QSFP Direct Attach (DAC) cable designed for short-range, high-bandwidth interconnects. As a passive copper assembly, the cable delivers low-latency, energy-efficient links between QSFP ports on switches, servers and storage systems. Its fixed 0.5 m length and QSFP connector interface simplify rack-level connectivity where reliable 40Gb/100Gb-class performance is required.
Advantages
The passive QSFP DAC design offers reduced power consumption compared with active optical transceivers and minimizes protocol overhead for latency-sensitive applications. The short, factory-molded assembly provides consistent signal integrity without the need for separate transceivers, reducing component count and simplifying inventory. Robust connector housings and a durable cable jacket make it suitable for dense rack environments and repeated insertions.
Suitable for
 Short-range QSFP-to-QSFP connections inside racks
 Switch-to-switch, server-to-switch and server-to-storage links
 High-density data center top-of-rack and middle-of-row deployments
 Low-latency networking for virtualization and storage clusters
Key specifications
 Connector type: QSFP (Quad Small Form-factor Pluggable)
 Cable type: Passive copper twinax assembly
 Length: 0.5 m (fixed)
 Supported link classes: 40Gb and 100Gb topology compatibility
 Latency: low, suitable for latency-sensitive applications
 Power: passive design with minimal power draw
 Operating environment: intended for data center and rack use
How to use
Insert each QSFP connector into the corresponding QSFP port on the network devices until the connector latches. Ensure both devices are powered and configured to accept 40Gb/100Gb direct attach links. Verify link status through the device management interface and monitor for proper negotiation and error-free operation. For correct airflow and cable management, route the 0.5 m cable without sharp bends and avoid excessive strain on the connectors.
Usage recommendations
Use this passive DAC for short, fixed-length connections within the same rack or adjacent racks. Avoid using it for distances beyond its specified length or in environments with significant electromagnetic interference. For environments requiring longer runs or fiber-based isolation, consider active or optical transceiver solutions.
