## Summary description

Direct-attach copper (DAC) cable CBO P5Y0N, QSFP28 interface, 30 m length. Designed for short to mid-range high-speed connections between QSFP28 ports in data centers and network equipment. Provides a fixed copper connection for 100GbE or compatible QSFP28 devices, simplifying cabling and reducing latency and power compared with active optics in supported setups.

## Long description

The BlueOptics DAC cable CBO P5Y0N is a 30 metre QSFP28 direct-attach copper cable designed for short- to mid-range high-speed links between QSFP28 ports. It provides a fixed copper connection for 100 Gigabit Ethernet or other QSFP28-compatible devices in data centre racks and network equipment. The passive copper construction minimises latency and power consumption compared with active optical transceivers where passive direct-attach copper is supported, while delivering the signal integrity required for 100GbE links at this distance.
Advantages
This QSFP28 direct-attach copper cable offers a reliable, low-latency physical connection suited to top-of-rack and adjacent-rack deployments. The 30 m length enables flexible placement of switches and servers without the need for active transceivers or separate fibre patching in short to mid-range scenarios. The fixed copper assembly reduces power and complexity, simplifies inventory and installation, and supports standard QSFP28 port pinouts for straightforward interoperability with compatible equipment.
Suitable for
100 Gigabit Ethernet links between QSFP28 ports in data centres
Top-of-rack and adjacent-rack switch-to-switch or switch-to-server connections
High-density rack environments where passive copper connectivity is preferred
Short- to mid-range links where cost, power and latency optimisation is required
Key specifications
Interface: QSFP28 direct-attach copper
Length: 30 metres
Supported data rate: up to 100 Gb/s (QSFP28-compatible)
Cable type: passive copper assembly
Typical application: short- to mid-range data centre interconnects
How to use
Install the DAC by inserting each QSFP28 connector into the corresponding QSFP28 port on your network devices, ensuring port orientation and latching are correct. No separate transceivers or fibre patching are required. Verify that connected equipment supports passive QSFP28 direct-attach copper cables and is configured for the intended 100GbE or compatible link speed. Monitor link status indicators on the devices to confirm successful negotiation and operation.
Usage recommendations
Route the cable with gentle bends and avoid tight radii to preserve signal integrity. Use appropriate cable management to prevent mechanical strain on connectors and to maintain airflow in racks. Confirm compatibility with your hardware vendor documentation for passive QSFP28 DAC usage and any transceiver or port firmware requirements.
