## Long description

The BlueOptics SFP-BXD43-40KM-NK-BO network transceiver module is a single-port SFP fiber optic module designed for serial data transmission at up to 1250 Mbit/s. Housed in a metal enclosure, this module meets RoHS requirements and is intended for point-to-point optical links where stable, long-distance connectivity is required. The module’s compact SFP form factor allows compatibility with a wide range of switches, routers and optical equipment that accept standard SFP transceivers.
Advantages
The metal housing provides electromagnetic shielding and mechanical protection while helping to dissipate heat. Compliance with RoHS ensures the module meets environmental and safety directives for restricted substances. The SFP form factor and 1250 Mbit/s data rate make the module suitable for standard Gigabit-compatible serial optical links, and its design supports reliable transmission over extended fiber distances.
Suitable for
Point-to-point fiber optic links in campus and metropolitan networks
Upgrade or expansion of network switch and router ports that support SFP modules
Backbone connections requiring stable 1250 Mbit/s serial links
Replacement of existing SFP transceivers with a RoHS-compliant metal-housed module
Key specifications
Interface type: SFP
Maximum data transfer rate: 1250 Mbit/s
Housing: metal enclosure for shielding and durability
Environmental compliance: RoHS compatible
Weight: approximately 0.2 kg
How to use
Install the BlueOptics SFP-BXD43-40KM-NK-BO by inserting the module into a compatible SFP slot on your switch, router or optical transceiver bay until it clicks into place. Connect the appropriate single-mode or multimode fiber cable and secure any required connectors. Confirm link status through the host device’s management interface and verify that the device negotiates or is configured for the required 1250 Mbit/s serial link. Follow the host equipment manual for hot-plug handling and ESD precautions.
Usage recommendations
For optimal performance, use clean, certified fiber connectors and follow standard fiber handling procedures. Verify compatibility with the host device SFP specifications before installation and ensure network configurations match the 1250 Mbit/s link speed. Store unused modules in anti-static packaging and avoid exposure to excessive dust or moisture.
