Network adapter CBO SU57AG-BO Copper 1250 Mbit/s RJ-45

CBO SU57AG-BO Copper 1250 Mbit/s RJ-45 is a wired network adapter designed to provide multi-gigabit Ethernet connectivity over standard copper cabling. The adapter supports up to 1250 Mbit/s throughput via an RJ-45 port and is intended for use in desktops, servers or network appliances that require reliable high-speed wired connections. Its compact interface and compatibility with common Ethernet infrastructures make it suitable for upgrading existing systems to faster wired performance while maintaining plug-and-play simplicity.

Advantages

The adapter delivers increased data transfer rates up to 1250 Mbit/s on copper cabling while using a standard RJ-45 connector, enabling faster wired networking without replacing physical cabling in many environments. It is compatible with typical desktop and server platforms, providing stable throughput and low-latency performance for applications that demand consistent network behavior. The device is designed for easy installation and immediate operation, minimizing setup time for system upgrades.

Suitable for

• Upgrading desktop workstations to multi-gigabit wired Ethernet
• Adding high-speed network connectivity to servers or small NAS devices
• Connecting network equipment where fiber is not available but higher-than-gigabit speeds are needed
• Environments requiring stable, low-latency wired connections for data transfer and streaming

Key specifications

• Interface: RJ-45 copper Ethernet port
• Maximum data rate: 1250 Mbit/s
• Connection type: Wired Ethernet (copper)
• Form factor: external network adapter (compact interface for host connection)
• Compatibility: standard Ethernet cabling and network equipment supporting multi-gigabit over copper

How to use

Install the adapter into an available slot or interface on the target device following the manufacturer’s physical installation instructions for your platform. Connect a compatible Ethernet cable (CAT5e or higher, as required for multi-gigabit operation) to the RJ-45 port and to the network switch or router. The adapter supports plug-and-play operation on many systems; if necessary, install or update drivers provided by the device manufacturer to enable full functionality and optimal performance. Verify link speed and network settings in the operating system or network management tools after installation.

Usage recommendations

For reliable multi-gigabit performance, use quality twisted-pair cables rated for the target speed (CAT5e for lower multi-gig settings, CAT6/CAT6a or better for consistent 1250 Mbit/s over longer runs) and ensure connected switches or routers support the required link speed. Keep device firmware and drivers up to date and verify auto-negotiation settings if link speeds do not reach expected rates.
