## Long description

BlueOptics CBO QSFP28-DAC-2M is a 2 meter passive copper direct-attach cable (DAC) engineered for QSFP28 ports. It enables a direct QSFP28-to-QSFP28 connection without transceivers, providing a practical solution for short-reach interconnects in racks and within data center topologies. The cable supports compatible 100GbE equipment, offering low latency and straightforward plug-and-play installation for switches, servers and network appliances.
Advantages
The passive copper construction delivers low power consumption and minimal signal processing overhead, resulting in reduced latency compared with optical transceivers. At 2 meters length the cable is optimized for short-distance links inside racks or between adjacent racks, simplifying cable management and lowering overall deployment cost. The QSFP28 connector form factor maintains compatibility with standard QSFP28 ports and requires no additional optics or configuration, enabling fast, reliable connections.
Suitable for
Short-reach 100GbE interconnects between QSFP28 ports in rack-mounted switches and servers
Top-of-rack (ToR) and adjacent-rack connections in data centers
High-density environments where cost and power efficiency are priorities
Environments requiring plug-and-play cabling without separate optical modules
Key specifications
Cable type: passive copper direct-attach (DAC)
Connector type: QSFP28 to QSFP28
Supported link speed: compatible with 100 Gigabit Ethernet (100GbE)
Length: 2 meters
Design: low-latency, short-reach interconnect
How to use
Insert each QSFP28 connector into the corresponding QSFP28 port on your switch, server or network appliance until the latch engages. No additional configuration or optical modules are required. Verify link status using the host device’s interface indicators or management software. For best results, route the cable to avoid tight bends and secure it to rack infrastructure as needed to reduce strain on connectors.
Usage recommendations
Use this 2 m passive DAC for intra-rack or nearby inter-rack 100GbE connections where short reach and low latency are required. Avoid routing through areas with high electromagnetic interference and keep bend radius within manufacturer guidelines to maintain signal integrity.
