## Summary description

Passive 3 m InfiniBand direct attach cable from CBO, model QFX-QSFP-DAC-3M-BL. Equipped with QSFP+ connectors for short-reach high-speed links between switches, network adapters or storage devices. Designed for reliable low-latency connections in data centers and server racks. Suitable for linking compatible QSFP+ ports where active optics are not required.

## Long description

The CBO InfiniBand Cable QFX-QSFP-DAC-3M-BL is a 3 m passive QSFP+ direct attach copper cable designed for short-reach, high-bandwidth connections. It provides a low-latency physical link between QSFP+ ports on switches, host adapters and storage devices. The cable is intended for use in data center and server rack environments where reliable, cost-effective copper connectivity is preferred over active optical modules for distances within the supported reach.
Advantages
This passive QSFP+ cable offers predictable performance for short-distance interconnects, with lower power consumption than active transceivers. The direct attach copper construction reduces latency and simplifies installation by providing a single-cable solution without separate SFP/QSFP modules. Its 3 m length fits typical rack-to-rack and within-rack topologies, enabling straightforward connections between compatible QSFP+ ports while avoiding the need for fiber patching or additional transceiver inventory.
Suitable for
Short-reach interconnects between top-of-rack or end-of-row switches
Connections from servers or NICs to switch QSFP+ ports in the same rack
High-throughput links for storage arrays and converged infrastructure
Low-latency links in high-performance computing and InfiniBand fabrics
Key specifications
Connector type: QSFP+ on both ends
Length: 3 metres (passive copper)
Media: Direct attach copper (DAC)
Intended use: Short-reach, high-bandwidth links
Typical environments: Data centers, server racks, HPC clusters
How to use
Install the cable by seating each QSFP+ connector into the corresponding QSFP+ port until the latch engages. Ensure both connected devices are powered down or the ports are active and compatible according to the equipment documentation. Verify link status on connected devices after insertion and check port indicators or management interfaces for proper negotiation. For removal, disengage the latch and pull the connector straight out to avoid damaging the port.
Usage recommendations
Use this passive 3 m QSFP+ cable for intra-rack and short inter-rack connections where passive copper meets your distance and bandwidth requirements. Confirm QSFP+ port compatibility with the switch or host vendor and avoid excessive bending or undue mechanical stress on the cable to maintain signal integrity and connector longevity.
