## Long description

The BlueOptics SFP-BXD43-20KM-SW-BO is a fiber optic SFP transceiver module designed for single-port network links with a data transfer rate up to 1250 Mbit/s. Housed in metal, the compact module weighs approximately 20 g and supports reliable optical transmission over extended distances. It is compatible with standard SFP slots and intended for integration into switches, routers and media converters where a small form-factor pluggable solution is required.
Advantages
The metal housing provides mechanical durability and helps with heat dissipation during continuous operation. With a standard SFP interface and a 1250 Mbit/s line rate, the module offers straightforward installation and interoperability with equipment that supports SFP optics. The lightweight, compact design minimizes space usage in network racks and allows easy hot-swapping without interrupting adjacent ports.
Suitable for
Point-to-point fiber connections between switches or routers
Long-distance uplinks in enterprise and campus networks
Fiber links in telecom and data center edge applications
Key specifications
Interface type: SFP (small form-factor pluggable)
Maximum data transfer rate: 1250 Mbit/s
Housing material: metal
Weight: 0.02 kg
How to use
Install the BlueOptics SFP-BXD43-20KM-SW-BO into a compatible SFP slot on the target device until it seats firmly. Connect the appropriate single-mode fiber patch cable to the module’s optical port following correct polarity. After insertion, verify link status on the host device and configure interface settings as required for your network (speed, duplex, and optical diagnostics). Remove the module by releasing the latch or pull-tab per the device manual to avoid damage.
Usage recommendations
For reliable long-distance performance, use single-mode fiber of appropriate attenuation rating and keep connectors clean to minimize insertion loss. Confirm that the host device supports 1250 Mbit/s SFP optics and check firmware compatibility if link negotiation issues occur.
