## Summary description

Passive DAC (direct-attach copper) cable CBO QFX-QSFP-DACBO-1M-BL is a 1-meter QSFP interconnect supporting 40 Gbit/s links. Designed for short-range connections between switches, routers or servers with QSFP ports, it provides a compact, low-latency, and power-efficient cabling option for data center top-of-rack and aggregation use cases.

## Long description

Passive DAC (direct-attach copper) cable BlueOptics CBO QFX-QSFP-DACBO-1M-BL is a 1-meter QSFP interconnect engineered for 40 Gbit/s links. It is intended for short-range connectivity between network devices equipped with QSFP ports, offering a compact and low-latency physical connection suitable for data center top-of-rack and aggregation layers. The cable uses a copper twinax design and requires no external transceivers, simplifying installation and reducing power consumption compared with active optical modules.
Advantages
This 1 m QSFP direct-attach copper cable delivers full 40 Gbit/s bandwidth with minimal latency and predictable performance for short link distances. Its passive construction eliminates the need for separate transceivers, lowering both upfront and operational energy costs. The cable's fixed length and robust connectors ensure reliable mating with QSFP ports and a tidy cable layout in high-density racks.
Suitable for
Top-of-rack switch-to-switch connections in data centers
Server-to-switch aggregation links within the same rack
Patch connections in network aggregation and spine-leaf architectures
Key specifications
Form factor: QSFP (quad small form-factor pluggable) direct-attach copper
Length: 1 meter
Data rate: 40 Gbit/s
Transmission medium: passive twinax copper
Typical use: short-range, intra-rack and adjacent-rack connections
How to use
Install the cable by plugging each QSFP connector into the corresponding QSFP port on the network devices until the connector latches. Ensure both devices are powered down or that hot-plug is supported by the equipment before insertion or removal to avoid port damage. Verify link status on the devices after connection and confirm that the interfaces negotiate 40 Gbit/s where supported. Avoid sharp bends and excessive strain on the cable during routing and when securing in rack management channels.
Usage recommendations
Use this passive QSFP DAC for connections up to the recommended short-range distance within racks or between adjacent racks. For longer distances or when optical isolation is required, choose an active cable or fiber optic transceivers instead. Maintain bend radius and strain relief to preserve signal integrity and expected 40 Gbit/s performance.
