LC APC Duplex Keystone Adapter with Inner Shutter, 0.2dB Insertion Loss, and >1000 Matings Durability Fiber Optic Coupler

LC APC Duplex Keystone Adapter with Inner Shutter and Fl

This is a modular, snap-in fiber optic coupler designed to be mounted in a standard keystone wall plate, patch panel, or enclosure, providing a fixed interface for connecting two LC APC fiber optic cables.

Specification:

Features:

1.1 Standard Keystone Design: It has a rectangular plastic housing that snaps into any standard keystone wall plate, patch panel, or surface-mount box (like those from Leviton, Legrand, Panduit, etc.).

This allows for easy, tool-less installation and modular network setups.

1.2 Duplex Configuration: Contains two individual LC adapter sleeves side-by-side within one housing. Ensures the transmit and receive channels (often labeled "A" and "B" or color-coded with a black shutter for one port and a beige/white shutter for the other) are kept in proper polarity.

The duplex housing often has a small clip or latch on the side to allow duplex LC connectors (two connectors clipped together) to be easily inserted and removed as a single unit.

1.3 APC Specifics: Color is Green (the internal split sleeves and often the exterior shroud are green). The adapter is

keyed to ensure the APC connectors are rotationally aligned correctly for the 8° angle.

1.4 Shutters: Usually equipped with spring-loaded dust shutters that automatically close when a cable is unplugged. This protects the internal split sleeves from dust and contaminants, a critical feature in office or residential environments.

Application:

2.1 Fiber-to-the-Home (FTTH / PON Networks): Crucial for preventing interference between upstream and downstream signals in single-fiber bidirectional systems (like GPON).

2.2 Cable Television (CATV) & RF Video Systems: Analog signals are highly sensitive to back reflections, which cause ghosting and signal degradation.

2.3 High-Speed Digital Systems/WDM (Wavelength Division Multiplexing): Lasers used in these systems are sensitive to reflected light, which can cause instability, noise, and reduced performance.

2.4 Test/Measurement Equipment: Used for accurate measurements where reflections must be minimized.
