## Summary description

The BlueOptics SFP-BXD43-40KM-QL-BO is a fiber optic SFP transceiver module with a maximum data transfer rate of 1250 Mbit/s. It features a metal housing and complies with RoHS standards. Weighing 200 g, it is designed for reliable network connections over long distances.

## Long description

The BlueOptics SFP-BXD43-40KM-QL-BO network transceiver module Fiber optic 1250 Mbit/s is a small form-factor pluggable (SFP) fiber optic module designed for single-channel optical links. With a maximum data rate of 1250 Mbit/s and a metal housing, this transceiver is intended for reliable point-to-point connections over extended distances while meeting environmental directives such as RoHS. The compact module supports straightforward integration into SFP-compatible switches, routers and media converters and is suitable for installations where a compact, standardized optical interface is required.
Advantages
The module’s metal housing provides mechanical stability and helps dissipate heat during continuous operation. Compliance with RoHS ensures restricted use of certain hazardous substances. Its SFP form factor allows hot-plug capability and broad compatibility with networking equipment that accepts SFP modules. The specified 1250 Mbit/s transfer rate supports standard optical Ethernet and other serial optical links within the SFP performance class.
Suitable for
 Point-to-point fiber links between switches or routers
 Connections to media converters and optical line cards
 Network segments requiring a compact SFP transceiver for long-reach links
 Environments where RoHS-compliant components are required
Key specifications
 Form factor: SFP (small form-factor pluggable)
 Maximum data transfer rate: 1250 Mbit/s
 Physical housing: metal
 Weight: 0.2 kg
 Application: single-channel fiber optic transceiver for long-distance links
 Standards compliance: RoHS
How to use
Insert the module into an empty SFP slot on compatible switches, routers or media converters while the host device is powered on or off according to the equipment’s instructions. Connect the appropriate fiber optic cable to the module’s optical interface, ensuring correct connector type and polarity. Configure the host device’s port settings if necessary to match the required link speed and duplex or optical parameters. Verify link status through the host device’s management interface and test end-to-end connectivity after installation.
Usage recommendations
Store and handle the transceiver in a clean, dust-free environment and use protective caps on the optical connector when the module is not connected. Match fiber type and connector to the module’s intended application, and consult the host equipment compatibility list if available to ensure proper operation. For permanent installations, periodically check optical power levels and link status to maintain reliable performance.
