## Summary description

The BlueOptics 943 974-002-BO is an SFP transceiver module designed for fiber optic connections, offering a maximum data transfer rate of 1250 Mbit/s. It features a silver color, operates at an input voltage of 3.3 V, and has a compact form factor. This module is compatible with Hirschmann devices, making it ideal for networking applications.

## Long description

The BlueOptics 943 974-002-BO SFP transceiver is a compact fiber optic module designed for single-mode links with an LC (UPC) simplex connector. It supports a maximum data transfer rate of 1250 Mbit/s and transmission distances up to 20 km while operating from a 3.3 V supply. The silver-coloured, MSA-compliant SFP form factor provides electrical, mechanical and functional compatibility with Hirschmann platforms and other systems that accept standard SFP modules.
Advantages
This SFP transceiver supports 1000BASE-BX-U operation with separate transmit and receive wavelengths for up to 20 km single-mode links. It is manufactured to MSA specifications and undergoes compatibility testing for use in Hirschmann hardware, providing plug-and-play interoperability. The module includes support for digital diagnostics (DDM/DOM) for real-time monitoring of supply voltage, laser bias current, optical output and input power, and temperature. Components are selected from established suppliers to deliver long service life and high mean time between failures.
Suitable for
Gigabit Ethernet uplinks and long-distance fiber connections
Switches, routers and storage systems that accept SFP transceivers
Industrial and enterprise networks requiring single-mode LC simplex links
Key specifications
Data rate: up to 1250 Mbit/s
Maximum link distance: up to 20 000 m (single-mode)
Connector type: LC (UPC) simplex
Wavelength: 1310 nm (receive) and 1550 nm (transmit) for BX-U operation
Supply voltage: 3.3 V
Product colour: silver
Weight: approximately 0.02 kg
MSA-compliant SFP form factor with DDM/DOM support
How to use
Insert the SFP transceiver into an empty SFP slot on a compatible switch, router or other network device while the host device is powered according to the vendor's instructions. Connect an appropriate single-mode LC patch cable to the LC simplex port, ensuring the correct orientation for the BX-U pair (transmit on one wavelength and receive on the other). Verify link status and, if available, monitor diagnostic parameters via the host device to confirm optical power and temperature are within expected ranges. Follow the host device manual for enabling or configuring any port-specific settings.
Usage recommendations
Use single-mode LC patch cords rated for the specified distance and maintain clean connectors to avoid signal loss. Ensure the host hardware supports BX-U wavelengths and DDM/DOM if remote diagnostics are required. Store and handle the module according to ESD precautions and avoid exposure to contaminants on the optical interfaces.
