FDF (Fiber Distribution Frame)
An FDF is a device that allows an optical cable to be carried into the indoor space of a building with the appropriate adaptor to suit the user environment. The connector type and allowable number of core wires can be changed according to the user’s requirements.
Fiber Optic Patch Cord & Pigtail
The fiber optic patch cord and pigtail provide an interface for connecting optical fibers between equipment and/or FDFs. The type of optical fiber, connectors, grounding, diameter and length can all be specified according to the customer’s requirements.
This passive element functioning as an optical distribution unit applied to an FTTx network distributes a single optical input to several outputs of consistent optical power. Input and output connector types can be specified according to the customer’s requirements.
Field Assembly Connector
A field assembly connector is used to open a subscriber account on an FTTH network. It is used to connect the drop optical cable to the subscriber’s ONT. Field installation is facilitated by the use of mechanical connection rather than splicing.
Fiber Optic Closure
This is an instrument for distribution and connection of optical cables. Fiber optic closures are divided into closures for processing, closures for conduits, and closures for direct purchase. The allowable connection capacities are 48, 72 and 144 core wires.
