Green SM LC/APC Duplex Fiber Optic Adapter with Inner Shutter 0.2 dB Insertion Loss and 500 Cycle Durability

Green SM LC/APC Duplex Fiber Optic Adapter with Inner Shutter

A fiber optic LC APC adapter is a passive mechanical device designed to precisely align and join two LC-type fiber optic connectors that have an APC (Angled Physical Contact) polish, creating a continuous optical path for light signals with minimal loss and, critically, exceptionally low back reflection.

Specification:

Features:

1.1 LC: Stands for Lucent Connector (sometimes called "Little Connector"). It's a small-form-factor connector type that is extremely popular in high-density applications like data centers, telecommunications, and FTTH due to its compact size.

1.2 APC: Stands for Angled Physical Contact. This refers to the specific 8° angle polish applied to the end face of the fiber ferrule.

1.3 Adapter: The housing or sleeve that holds the two connectors in perfect alignment.

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.
