## Summary description

CBO DAC cable CAB-Q-Q-100G-50CM is a 50 cm direct-attach copper cable with QSFP28 to QSFP28 connectors supporting 100G data rates. Designed for short-reach interconnects between compatible switches, routers or servers, it provides a low-latency, energy-efficient connection without separate transceivers. Ideal for data center racks and server clusters.

## Long description

CBO DAC cable CAB-Q-Q-100G-50CM is a 50 cm direct-attach copper cable with QSFP28 to QSFP28 connectors that supports 100G data rates. It is designed for short-reach interconnects in data center environments, enabling direct connections between compatible switches, routers and servers without the need for separate optical transceivers. The cable offers a compact, low-power connection suitable for top-of-rack and adjacent-rack links where low latency and cost-effective cabling are required.
Advantages
The QSFP28 to QSFP28 direct attach design reduces component count and power consumption compared with optical transceiver plus fibre assemblies. With a 50 cm length, the cable simplifies cabling in dense rack layouts and minimizes signal loss over short distances. The integrated copper assembly delivers low latency and stable 100G throughput while removing the need for module compatibility checks and additional SFP or QSFP power draw.
Suitable for
Short-reach links inside data center racks (top-of-rack to switch)
Interconnects between adjacent racks or server rows
High-throughput server-to-switch or switch-to-switch connections
Environments where low latency and reduced power consumption are priorities
Key specifications
Connector type: QSFP28 to QSFP28
Data rate: 100 Gbps
Cable type: Direct-attach copper (DAC)
Length: 50 cm
Designed for short-reach, rack-level interconnects
Low-latency, fixed-assembly passive copper design
How to use
Insert each QSFP28 connector into compatible QSFP28 ports on network devices until the latch engages. Ensure ports are powered down or follow hot-plug safety procedures as recommended by the device manufacturer. After insertion, verify link status and speed through device management interfaces or LEDs. For removal, release the connector latch and pull straight out to avoid stressing the cable or port.
Usage recommendations
Use this 50 cm DAC cable for intra-rack and adjacent-rack connections where 100G links are required and short physical distance allows copper cabling. Avoid tight bends and excessive pulling; maintain manufacturer-recommended bend radius. Confirm compatibility with your equipment’s QSFP28 ports and port firmware; passive cables are typically suitable for short distances and may not support extended reach or active cooling benefits.
