## Long description

Direct Attach Copper (DAC) cable CBO JNP-100G-DAC-3M-BL is a 3-meter QSFP28 male assembly that supports 100 Gbit/s links. It is intended for short-reach interconnects in data centers and high-performance network environments, providing a low-latency, low-power electrical connection between QSFP28 ports on switches, routers and servers.
Advantages
This 3 m QSFP28 cable delivers 100 Gbit/s bandwidth with minimal latency and reduced power consumption compared with active optical solutions for short distances. The copper direct-attach design simplifies setup by offering a single, ready-to-use cable with integrated connectors and predictable electrical performance. Its fixed length and robust construction reduce signal loss and maintain stable throughput in dense rack environments.
Suitable for
 Short-reach interconnects between rack-mounted switches and servers
 High-density data center top-of-rack connections
 Aggregation and spine-leaf network links within a single room or adjacent racks
 Low-latency, high-throughput connections for storage and compute clusters
Key specifications
 Interface: QSFP28 male to QSFP28 male
 Rated data rate: 100 Gbit/s
 Cable length: 3 meters
 Cable type: Direct Attach Copper (passive DAC)
 Typical applications: short-reach interconnects in racks and adjacent racks
How to use
Install the cable by inserting each QSFP28 connector into the corresponding QSFP28 port on the devices until the latch engages. Ensure both ends are seated firmly and ports are powered off or follow hot-plug guidelines provided by your equipment vendor if connecting live. Verify link status through device LEDs or management interfaces and confirm negotiated speed at 100 Gbit/s. Avoid sharp bends and secure the cable to prevent strain on connectors.
Usage recommendations
Use this 3 m DAC cable for intra-rack or adjacent-rack connections where 100 Gbit/s performance is required and optical transceivers are not necessary. Keep the cable run within recommended bend radius limits, avoid running near high-heat sources, and check compatibility with QSFP28 ports on your network equipment to ensure proper electrical signalling and link negotiation.
