## Summary description

Passive copper direct attach (DAC) cable from CBO, model SFP28-DAC-0.5M with a 0.5 m length. Designed for SFP28 ports to provide short-reach 25GbE or compatible high-speed connections between switches, servers and network equipment. Pre-terminated and low-power solution that simplifies rack cabling and reduces latency for data center and enterprise environments.

## Long description

Passive copper direct attach (DAC) cable BlueOptics CBO SFP28-DAC-0.5M is a pre-terminated short-reach connection cable with a 0.5 m length designed for SFP28 ports. It provides a low-power, low-latency physical link for 25GbE and compatible high-speed interfaces between switches, servers and other network devices in rack and data center environments. The cable is factory-terminated on both ends to maintain signal integrity and simplify rack cabling without additional transceivers.
Advantages
This passive SFP28 DAC cable offers predictable electrical performance and reduced power consumption compared with active optical transceivers. Its short 0.5 m length minimizes signal degradation and latency for top-of-rack or adjacent-rack connections. Pre-termination eliminates the need for field termination and reduces installation time. The cable is compatible with standard SFP28 ports for straightforward integration into existing 25GbE-capable infrastructure.
Suitable for
Short-reach connections between top-of-rack switches and servers
High-density patching in data centers and server rooms
Interconnects between switches within the same rack or adjacent racks
Low-latency links for storage, virtualization and compute clusters
Key specifications
Connector type: SFP28 on both ends
Length: 0.5 m
Media: Passive copper direct attach
Supported data rate: 25 Gb/s (25GbE compatible)
Power consumption: passive (no active electronics in-line)
Form factor: low-profile, suitable for high-density racks
How to use
Insert each SFP28 connector into the corresponding SFP28 port on network equipment until the connector latches. Ensure that both connected devices support passive DAC cables and the intended 25GbE link speed. Configure network interfaces on connected devices for the correct speed and duplex settings if not negotiated automatically. Route the cable to avoid sharp bends and heavy strain; secure with cable management to maintain airflow and rack organization.
Usage recommendations
Use this 0.5 m passive DAC for short, direct connections inside racks or between adjacent racks. Verify port compatibility and vendor interoperability in your environment. Avoid repeated unplugging under load and keep bend radius above the manufacturer’s minimum to preserve signal integrity.
