## Summary description

CBO DAC cable CBL-0496L-BL is a 30 m QSFP passive direct-attach copper (DAC) cable designed for short- to mid-range high-speed interconnects between network equipment with QSFP ports. It provides a fixed, low-latency copper link without transceivers, suitable for switches, routers and servers in data centers where reliable, cost-effective board-to-board or rack-to-rack connections are required.

## Long description

CBO DAC cable CBL-0496L-BL is a 30 m QSFP passive direct-attach copper (DAC) cable engineered for short- to mid-range high-speed interconnects between network devices with QSFP ports. The cable provides a fixed copper link without active optical transceivers, delivering low latency and stable signal integrity for board-to-board or rack-to-rack connections in data center environments. It is intended for applications where predictable performance and reduced power consumption are priorities.
Advantages
The passive QSFP DAC cable offers a straightforward physical connection that eliminates the need for separate transceivers, reducing component count and simplifying installation. Its passive copper design minimizes power draw compared with active optical solutions while preserving high data-rate capability and low latency. The product is manufactured for consistent electrical characteristics across the 30 m length, supporting reliable link establishment and maintenance in dense networking setups.
Suitable for (tasks / use cases)
 Interconnecting switches and routers within and between racks in data centers
 High-speed links between servers and top-of-rack or spine switches
 Short- to mid-range interconnects where low latency and predictable performance are required
 Environments seeking cost-effective and low-power copper links instead of optical transceivers
Key specifications
 Connector type: QSFP form-factor direct-attach copper
 Cable length: 30 metres
 Cable type: Passive copper twinax
 Data rates: Designed for high-speed multi-lane QSFP links (multi-gigabit per lane aggregated throughput)
 Latency: Low, fixed-latency copper connection
 Intended deployment: Short- to mid-range rack-to-rack or board-to-board interconnects in data centers
How to use
Ensure both network devices support QSFP passive direct-attach copper connections and are powered down or follow hot-swap guidelines recommended by the device manufacturers. Align and insert each QSFP connector into the corresponding QSFP port until it seats securely and any latch engages. Verify link status through the device management interface or LED indicators. For removal, release the connector latch and withdraw the cable straight out to avoid stressing ports. Follow standard cable routing practices and avoid sharp bends along the cable length to maintain signal integrity.
Usage recommendations
Use this passive DAC cable in controlled data center environments where distance requirements match the 30 m length. Avoid outdoor installation and exposure to moisture or extreme temperatures. Keep the cable clear of high electromagnetic interference sources and maintain appropriate bend radius as specified by equipment vendors to ensure stable performance.
