The function of the fiber patch panel is to terminate the fiber optic cable and provide access to the individual optical fiber cable for cross-connection. The fiber patch panels can be cross-connected using fiber jumpers, connected to fiber optic communications equipment, or tested for individual fibers in the fiber optic cable.
A fiber patch panel is usually composed of two parts, a compartment containing a fiber optic adapter (bulkhead receptacle), and a compartment comprising an optical fiber splice tray and an excess fiber cable. If you want more uniform cable management, you can also use fiber jumpers to manage trays and neatly store and manage excess fiber jumper cable lengths.
The fiber patch panel consists of a duplex SC adapter, a hybrid adapter, or a small (SFF) jack array. If the entire installation (including a fiber hub, repeater, or network adapter) uses the same type of fiber optic connector, the array can consist of a compatible adapter or jack. To switch between fiber connector types, you need a hybrid adapter or a conversion cable. The hybrid adapter is a passive coupler that connects two different connector types, and the conversion cable simply has a connector type at one end and the other end at the other end.
The fiber patch panel provides a convenient way to rearrange fiber connections and circuits. A simple wiring board is a metal frame that contains a sleeve, where the fiber optic cable connector is inserted on both sides. The side of the panel is usually fixed, which means that the fiber optic cable is not intended to be disconnected. On the other side of the panel, you can connect and disconnect the fiber optic cable to arrange the circuit as needed.
The fiber patch panels are mainly housed in 19-inch relay racks, but can also be mounted on separate rails, cabinets and walls. For fiber-optic cabling installation, you should carefully plan the location of the fiber-attached hardware, including the fiber-optic patch panel.
