Product Description

SC to SC OM4 Multimode Simplex Fiber Optic Keystone Coupler
A Fiber Optic Keystone Coupler is a critical passive component in optical fiber networks, designed to connect two fiber optic patch cords or pigtails within a structured cabling system. Engineered for easy integration into wall plates, patch panels, or surface-mount boxes, this coupler serves as a modular interface that enables flexible, reliable, and high-speed optical signal transmission. Ideal for both commercial and residential applications, it ensures minimal signal loss while facilitating quick installation and maintenance, making it an essential component for building scalable fiber networks.

Features

1. Fits standard keystone modules for snap-in installation, enabling easy integration into wall plates/patch panels and simplifying cable management.
2. Precision-aligned ferrules ensure minimal insertion loss , with wide temperature tolerance (-40°C to +85°C).
3. Supports connectors (LC/SC/ST, etc.) and both single-mode/multi-mode fibers, ensuring interoperability with multi-vendor equipment.

Applications

1. Enables high-density fiber patch panel setups for flexible, high-speed (10G+) network configurations.
2. Modular wall plate termination for residential fiber networks, ideal for retrofitting existing homes with minimal rewiring.
3. Weather-resistant design for harsh settings (factories, surveillance systems), ensuring reliable operation in dusty/moist conditions.
4. Supports high-speed backhaul in 5G base stations/telecom centers, delivering low-latency, stable signal transmission for critical networks.

Quality Testing Program

IL and RL Testing

 

Conduct testing on the insertion loss and return loss of cables to verify their reach and ensure stable signal transmission.

3D Interferometer Testing

 

Evaluate the connectors or ferrules of cables to verify that the apex offset, radius of curvature, and fiber height are within the specified parameters, ensuring a successful connection of fiber optic lines.

End-Face Inspection

 

Examine the connector end face for any scratches, defects, or contamination to ensure the tips remain clean. This practice enhances communication quality and reliability, thereby contributing to network uptime.
