## Long description

The BlueOptics SFP-BXD43-40KM-SO-BO is an SFP fiber optic transceiver module designed for single-channel data links with a maximum transfer rate of 1250 Mbit/s. Housed in metal and compliant with RoHS standards, this module supports reliable optical connections over long distances and is suitable for integration into networking equipment that accepts standard SFP form factor transceivers.
Advantages
The metal housing provides mechanical robustness and improved thermal dissipation for stable operation. Compliance with RoHS ensures the module meets environmental and safety directives. The SFP form factor offers hot-pluggable convenience and compatibility with a wide range of switches, routers and optical equipment that accept SFP modules. The 1250 Mbit/s line rate supports standard synchronous and asynchronous serial optical interfaces.
Suitable for
Single-mode fiber links requiring compact SFP transceivers
Long-distance optical connections in metropolitan or campus networks
Replacement or upgrade of existing SFP ports in switches and routers
Industrial or telecom installations where RoHS compliance is required
Key specifications
Interface type: SFP (Small Form-factor Pluggable)
Maximum data transfer rate: 1250 Mbit/s
Housing material: metal for improved durability and heat dissipation
Environmental standard: RoHS compliant
Weight: approximately 0.2 kg
How to use
Install the transceiver into a compatible SFP slot on your switch, router or optical transceiver bay while the host device is powered down or follow the host’s hot-swap guidance. Connect single-mode fiber with appropriate connectors to the module’s optical interface, ensuring correct transmit/receive alignment. Verify link status and configure the network device as required for the 1250 Mbit/s optical link. Follow standard fiber handling procedures to avoid contaminating connector end-faces.
Usage recommendations
Handle the module by its housing and protect the optical port with dust caps when not in use. Confirm compatibility with the host device and use clean, tested single-mode fiber cables for reliable long-distance performance. For critical deployments, perform link testing and monitor signal quality after installation.
