## Summary description

The BlueOptics SFP-BXU35-20KM-NK-BO is a fiber optic SFP transceiver module with a maximum data transfer rate of 1250 Mbit/s. It features a metal housing and weighs 20 g, ensuring durability and reliability with an MTBF of 1,000,000 hours. Ideal for high-speed data transmission in networking applications.

## Long description

The BlueOptics SFP-BXU35-20KM-NK-BO is an SFP fiber optic transceiver module designed for single-mode 1000BASE-BX-U data links. It supports a maximum data transfer rate of 1250 Mbit/s and implements LC simplex connectivity for single-fiber send/receive operation. The module comes in a metal housing with a silver finish, weighs approximately 0.02 kg, and is specified with a high MTBF for reliable operation in networking environments.
Advantages
This SFP transceiver offers single-mode fiber transmission over distances up to 20 kilometers using a wavelength pair for bidirectional communication. The compact SFP form factor ensures compatibility with MSA-compliant ports and common network hardware. The metal housing provides mechanical durability and thermal stability for continuous operation. The module supports digital diagnostic monitoring when the host system implements the required interface, enabling real-time parameter access for maintenance and troubleshooting.
Suitable for
Gigabit Ethernet links over single-mode fiber
Interconnection of switches, routers and storage equipment supporting SFP modules
Long-reach fiber links up to 20 km in campus and metro networks
Environments requiring compact, hot-pluggable transceivers
Key specifications
Interface type: SFP (MSA compliant)
Data rate: up to 1250 Mbit/s (1.25 Gbit/s)
Fiber type: single-mode fiber
Connector: LC simplex
Wavelengths: bidirectional pair (separate transmit and receive wavelengths)
Maximum reach: up to 20 km
Housing: metal, silver color
Weight: approx. 0.02 kg
Mean time between failures (MTBF): high (product specified for long operational lifetime)
How to use
Install the SFP transceiver into an MSA-compliant SFP port on supported network equipment while the device is powered according to the manufacturer's hot-plug guidelines. Connect an LC simplex single-mode fiber patch cable between transceivers at each end of the link, ensuring correct orientation for the transmit and receive wavelengths. Confirm link status and speed via the host device management interface. If digital diagnostic monitoring is required, enable and read the DDM/DOM parameters through the host system that supports this feature.
Usage recommendations
Ensure the host hardware and software officially support third-party SFP modules and that fiber connectors and patch cords are clean and appropriate for single-mode operation. Observe ESD precautions during handling and avoid exposing the module to excessive mechanical stress or contamination. For best long-term performance, verify compatibility and, if possible, test the module in your actual hardware setup before wide deployment.
