Black Box FOT123 Fiber Optic Coupling
Overview
The Black Box FOT123 is a duplex fiber optic coupling designed to bridge multimode and singlemode fiber optic connections. It features a ceramic sleeve for precise alignment and a durable plastic flange for secure mounting. This coupling is essential for extending or repairing fiber optic runs in surveillance systems where signal integrity between different fiber types is critical. Its black color ensures it blends discreetly into most installation environments.
Compatibility
This coupling is designed for general fiber optic connectivity and is compatible with standard duplex fiber optic cables utilizing LC, SC, or ST connectors, provided they are terminated for either multimode or singlemode transmission. It facilitates the interconnection of fiber optic transceivers, patch panels, and active network equipment across mixed fiber environments.
Installation Notes
Ensure that both fiber optic cables being connected are clean and free of debris before insertion into the coupling. The ceramic sleeve requires careful handling to maintain alignment accuracy. The plastic flange provides a mounting point, typically for integration into patch panels or equipment chassis.
