## Summary description

Passive direct attach copper (DAC) cable CBO QSFP-100G-C50CM, 50 cm length, designed for QSFP‑28 ports supporting 100G connections. Suitable for short-reach server-to-switch or switch-to-switch links in data centers and network racks. Provides low-latency, energy-efficient connectivity without transceivers; ideal for high-density equipment interconnects.

## Long description

BlueOptics DAC cable CBO QSFP-100G-C50CM is a 50 cm passive direct-attach copper (DAC) assembly with QSFP‑28 connectors on both ends, engineered for 100G links between QSFP‑28 ports. The cable provides a compact, low-latency electrical connection for short-reach server-to-switch and switch-to-switch interconnects in data centers and network racks. As a passive solution it eliminates the need for separate transceiver modules, reducing power consumption and simplifying high-density deployments.
Advantages
This passive QSFP‑28 to QSFP‑28 cable delivers predictable electrical performance with minimal latency and low power usage compared with active optics or transceiver-based links. The short 50 cm length is optimized for rack-level connections and high-density top-of-rack environments, enabling simple plug-and-play installation and reliable 100G throughput. The cable construction supports consistent signal integrity for short-distance links while reducing component count and maintenance.
Suitable for
 Short-reach server-to-switch connections in rack environments
 Switch-to-switch interconnects within the same rack or adjacent racks
 High-density 100G ports where low latency and low power are priorities
 Data center consolidation projects and equipment refreshes requiring cost-effective cabling
Key specifications
 Connector type: QSFP‑28 to QSFP‑28
 Cable type: Passive direct attach copper (DAC)
 Rated data rate: 100 Gbps
 Length: 50 cm
 Application: Short-reach rack-level interconnects
 Latency: Minimal electrical latency for short links
How to use
Install the cable by inserting each QSFP‑28 connector into compatible QSFP‑28 ports until the latch engages. Ensure ports are powered down or follow hot-swap procedures recommended by your hardware vendor if connecting live. Verify link status and speed in the host or switch management interface after insertion. For removal, release the connector latch and pull straight out to avoid stressing the port or cable.
Usage recommendations
Use this 50 cm passive DAC cable for short, rack-level 100G connections where transceiver-free, low-power links are desired. Avoid routing the cable with tight bends; maintain manufacturer-recommended bend radius and keep the assembly away from high-heat sources. Confirm compatibility with your switch or server vendor’s supported direct-attach cable list if required by warranty or interoperability policies.
