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.
