## Summary description

Direct attach copper (DAC) cable by CBO, model QSFP-4X25G-C1M, offering 4×25G lanes and a 1 m length. Designed for QSFP ports, it provides low-latency, short-reach connectivity between switches, routers or servers in data centers and network racks. Suitable for high-density 100G links where a fixed copper link reduces power and cost compared with optical transceivers.

## Long description

Direct attach copper (DAC) cable CBO QSFP-4X25G-C1M is a 1 m QSFP-to-QSFP cable engineered for short-reach, high-density 100G links. With four 25G lanes it provides a fixed, low-latency electrical connection between QSFP ports in switches, routers and servers. The cable is intended for use in data centers and network racks where power efficiency and cost-effectiveness are priorities compared with optical transceivers.
Advantages
This QSFP to QSFP direct attach cable delivers immediate, low-power connectivity with minimal configuration required. Its fixed copper construction reduces latency compared to optical modules and eliminates the need for separate transceivers and fiber patching for short links. The compact 1 m length supports high-density rack deployments while helping to simplify cabling management and lower total operating cost for 100G interconnects.
Suitable for
 Short-reach 100G interconnects between switches in the same rack or adjacent racks
 Connections between QSFP-enabled routers and servers in data center top-of-rack setups
 High-density aggregation and spine-leaf network fabrics requiring multiple parallel lanes
 Environments where reduced power consumption and cost per port are important
Key specifications
 Interface: QSFP to QSFP electrical direct attach
 Lane configuration: 4 × 25 Gbps lanes (total 100 Gbps aggregated)
 Length: 1 metre
 Media type: Passive copper twinax (direct attach copper)
 Typical use: Short-reach connections inside racks or between adjacent racks
How to use
Install the cable by inserting each QSFP connector into the corresponding QSFP port until it latches; ensure both ends are seated and latched securely. Verify link status on connected devices and configure port settings (speed, lane mapping, and any required link negotiation) according to your switch or server documentation. For systems that report cable presence, confirm the connection is recognized and test throughput to validate 100G operation across the four 25G lanes.
Usage recommendations
For reliable performance, use the cable for short, intra-rack or adjacent-rack links and avoid unnecessary bending or compression. Confirm compatibility of QSFP ports on both devices and follow vendor guidelines for supported DACs to ensure proper operation and warranty support.
