## Summary description

CBO DAC cable QSFP-4X25G-C5M is a passive direct-attach copper interconnect with a QSFP connector supporting four 25Gbps lanes (total 100Gbps) and a fixed 5 m length. Designed for short-reach, high-bandwidth connections between switches, routers or network appliances, it provides low-latency, power-efficient connectivity in data center and rack-to-rack setups.

## Long description

CBO DAC cable QSFP-4X25G-C5M is a passive Direct Attach Copper (DAC) cable with a QSFP connector that carries four 25Gbps lanes for a total aggregate bandwidth of 100Gbps. With a fixed length of 5 m, this cable is intended for short-reach, high-bandwidth interconnections in data center and rack-to-rack environments. The passive copper design delivers low latency and low power consumption compared with active optics for comparable short distances, making it suitable for switch-to-switch, switch-to-server, or appliance-to-appliance links where high throughput and cost-efficiency are required.
Advantages
The cable offers 100Gbps aggregate throughput from four independent 25Gbps lanes, providing sufficient bandwidth for modern 100GE fabrics. Being a passive copper assembly, it eliminates the need for separate transceivers, reducing hardware count and power draw. Its fixed 5 m length simplifies inventory and deployment for common rack-to-rack spans, while the QSFP connector ensures compatibility with equipment that supports QSFP form-factor direct-attach connections. The construction supports low-latency signaling and stable electrical performance across short distances.
Suitable for
 Short-reach connections between data center racks and top-of-rack switches
 High-bandwidth links between switches, routers and network appliances
 Server-to-switch connections within the same equipment room
 Temporary or permanent interconnects in clustered compute and storage environments
Key specifications
 Connector type: QSFP (Quad Small Form-factor Pluggable)
 Lane configuration: 4 × 25Gbps (aggregate 100Gbps)
 Length: 5 metres (fixed)
 Type: Passive direct-attach copper cable
 Typical use: Short-reach, rack-to-rack and in-rack interconnects
How to use
Install the cable by inserting each QSFP end into the corresponding QSFP ports on two compatible devices until the latch engages. Ensure devices are powered down or follow hot-plug instructions provided by the equipment manufacturer when connecting to live systems. After physical connection, verify link status and speed via the devices' management interfaces and configure the interfaces as required by your network design. Avoid excessive bending of the cable and route it to prevent mechanical strain or interference with airflow in racks.
Usage recommendations
Use this 5 m passive DAC where short, high-throughput links are needed and where power efficiency and cost-effectiveness are priorities. Confirm QSFP port compatibility and supported link rates on both endpoints before deployment. Maintain appropriate rack cable management and avoid tight bends or kinks to preserve signal integrity and mechanical reliability.
