## Summary description

Single-mode SC/APC duplex optical coupler for OEM applications. Designed for connecting two single-mode fibers with SC/APC connectors in a duplex configuration, it provides low insertion loss and reliable alignment for telecommunication, FTTH, and data network installations. Suitable for equipment manufacturers and installers seeking compact, standardized fiber coupling.

## Long description

Optical coupler SC/APC single-mode duplex OEM is a compact fiber coupling component designed to join two single-mode fibers with SC/APC connectors in a duplex configuration. Engineered for OEM use, the coupler provides precise mechanical alignment between mating SC/APC ferrules to ensure stable signal transmission with low insertion loss. It is suitable for integration into telecommunication equipment, FTTH terminals, patch panels, and custom networking devices where standardized duplex fiber connection is required.
Advantages
The coupler offers low insertion loss and stable optical performance due to accurate ferrule alignment and consistent connector geometry. Its duplex SC/APC form factor supports two independent single-mode channels in a small footprint, enabling compact device layouts. The design is compatible with industry-standard SC/APC connectors, which facilitates easy integration into existing fiber systems and reduces assembly time for manufacturers and installers.
Suitable for
 Telecommunication equipment assembly
 FTTH termination panels and customer premises equipment
 Data center and enterprise fiber patching
 OEM devices requiring standardized duplex single-mode connections
 Field installations and fiber optic repair work
Key specifications
 Connector type: SC/APC duplex
 Fiber type: Single-mode
 Configuration: Duplex coupling (two channels)
 Typical insertion loss: Low (optimized for single-mode links)
 Return loss: High (APC angled polish for improved back reflection)
 Mounting: Panel or adapter-style integration suitable for OEM assemblies
 Operating environment: Designed for indoor telecommunication and networking equipment
How to use
Install the duplex coupler in the designated panel cutout or adapter slot of the OEM device, ensuring secure mechanical retention. Align and insert SC/APC connectors from the incoming and outgoing single-mode fibers into each coupling port until the connectors seat fully. Verify optical continuity and measure insertion loss using appropriate test equipment. For multi-port assemblies, maintain consistent connector orientation to preserve duplex channel mapping.
Usage recommendations
Handle connectors and ferrules with care to avoid contamination; use lint-free wipes and fiber-grade cleaning solution before insertion. Use strain relief and proper cable routing to prevent bending beyond recommended fiber bend radii. For installations requiring minimal back reflection and high return loss, use only SC/APC connectors mated to the APC coupler ports.
