SFP transceiver BlueOptics AXSK-CSFP-COP-BO 1250 Mbit/s RJ-45

The BlueOptics AXSK-CSFP-COP-BO is an SFP transceiver designed for 1250 Mbit/s links with an RJ-45 interface in a durable metal housing. This compact module weighs approximately 20 g and is built to MSA-compliant form factors for broad interoperability. With an MTBF around 1,000,000 hours, the transceiver is intended for stable network connectivity in environments that require reliable copper-based SFP solutions for up to 100 m connections.

Advantages

The module provides a standardized RJ-45 SFP interface for easy insertion into compatible ports and supports data rates up to 1250 Mbit/s, enabling gigabit-class Ethernet and related protocols. Its metal housing offers mechanical protection and thermal dissipation while the lightweight construction simplifies handling and installation. The product is manufactured to MSA specifications to ensure compatibility with a wide range of network devices and to support Digital Diagnostics Monitoring (where supported by host hardware) for remote signal and health information.

How to use

Install the BlueOptics AXSK-CSFP-COP-BO by inserting the transceiver into an SFP slot on a compatible switch, router or other network device until it latches. Connect a standard RJ-45 copper patch cable between the transceiver and the remote device or patch panel. Ensure the host device firmware or driver supports third-party SFP modules and that any required DDM/DOM monitoring features are enabled in the host if diagnostics are needed. Verify link negotiation and speed settings on both ends of the connection and perform connectivity tests after installation.

Recommendations

Use category-rated copper cabling (e.g., Cat5e or higher) for optimal 1 Gbit/s performance and keep cable length within recommended limits (up to 100 m). Install the transceiver in powered-off or live systems according to the host vendor guidelines and avoid excessive bending or stress on the RJ-45 cable. If remote diagnostics are required, confirm DDM/DOM support in the host device and monitor supply voltage, optical power and temperature through the management interface.
