## Long description

CBO QFX-QSFP28-DAC-2M is a 2-meter Direct Attach Copper (DAC) passive twinax cable with QSFP28 connectors on both ends, designed for short-reach 100GbE interconnects in data center environments. The cable is compatible with Juniper equipment and intended for use between switches, routers or between servers and top-of-rack switches where low latency and energy efficiency are priorities. As a copper DAC it provides a cost-effective alternative to optical transceivers for links within the same rack or adjacent racks.
Advantages
This QSFP28 to QSFP28 DAC cable delivers low latency and reduced power consumption compared with optical modules, and its passive twinax construction allows straightforward, plug-and-play deployment without the need for separate transceivers. The 2 m length is suitable for intra-rack and short inter-rack connections, offering reliable physical connection and predictable electrical performance for 100GbE links. Compatibility with Juniper equipment ensures straightforward integration in networks using the specified platform.
Suitable for
 Short-reach 100 Gigabit Ethernet links between switches and routers
 Server-to-switch connections in top-of-rack configurations
 Intra-rack and adjacent-rack cabling in data centers
 Environments where lower latency and reduced power draw are required
Key specifications
 Connector type: QSFP28 to QSFP28
 Cable type: Passive twinax (Direct Attach Copper)
