## Summary description

Optical Coupler ST Single Mode Simplex 3000 OEM is a single-mode, simplex optical coupler with ST connector interface designed for fiber-optic signal splitting or coupling in single-mode networks. Intended for OEM integration, it provides a compact solution for connecting or routing single-mode fibers in telecom, data and instrumentation applications where a single fiber path and ST termination are required.

## Long description

Optical coupler ST single-mode simplex 3000 OEM is a single-mode simplex optical coupler with an ST connector interface designed for straightforward coupling or routing of single-mode fibers. Intended for OEM integration, the coupler offers a compact footprint and standard ST termination for use in telecom, data transmission and instrumentation systems where a single fiber path is required.
Advantages
The ST single-mode simplex coupler provides low insertion loss and stable optical performance across the operating wavelength range typical for single-mode networks. Its compact mechanical design and standardized ST connection simplify integration into existing assemblies and panels. The product is optimized for OEM use, offering repeatable connector alignment and reliable mating cycles while maintaining consistent signal integrity.
Suitable for
 Single-mode fiber signal splitting and routing in telecom equipment
 OEM assemblies and internal fiber patching in network devices
 Laboratory and instrumentation setups requiring ST terminations
 Point-to-point single-fiber connections where simplex termination is needed
Key specifications
 Connector type: ST (bayonet-style) single-mode simplex
 Fiber mode: Single-mode
 Configuration: Simplex (single fiber path)
 Typical insertion loss: low (manufacturer typical values vary by assembly)
 Mechanical form: Compact OEM-ready module for panel or device integration
 Compatibility: Standard single-mode fiber systems and ST-compatible equipment
How to use
Install the optical coupler into the OEM assembly or panel location designed for ST-style terminations, ensuring proper mechanical fixation and strain relief for connected fibers. Align and insert the mating ST connector until the bayonet locks; verify optical continuity and signal levels with appropriate test equipment. Follow standard single-mode fiber handling procedures: keep connectors and fiber ends clean, avoid sharp bends, and secure fibers to prevent stress at the coupling point.
Usage recommendations
Use fiber cleaning tools before each connection to minimize insertion loss and back reflection. Verify performance after installation with an optical power meter and, if applicable, an OTDR to confirm expected loss and continuity. For long-term reliability, provide strain relief, avoid exposure to excessive vibration or moisture, and follow OEM integration guidelines for mounting and environmental protection.
