## Long description

DELOCK 86851 keystone module is a flat-format fiber optic connector module with an FC interface in a black housing. Its compact dimensions (16.5×24×21.8 mm) follow keystone standards, allowing quick snap-in mounting into keystone-compatible patch panels, wall plates and surface-mount boxes. The module provides a stable FC connection for single-fiber terminations and straightforward integration into structured cabling and fiber extension setups where space is limited.
Advantages
The module offers a standardized keystone form factor that simplifies installation into a variety of faceplates and enclosures without additional adapters. The FC connector provides a secure, threaded optical connection that maintains alignment and low optical loss in point-to-point fiber links. Its flat design and black finish enable discreet placement in visible installations while preserving access for maintenance and fiber handling.
Suitable for
 Extending single-mode or multimode fiber runs that use FC terminations
 Keystone patch panels and modular wall plates with keystone cutouts
 Surface-mount boxes and custom enclosures requiring a compact fiber feed-through
 Telecommunication racks, server rooms and AV installations with limited space
Key specifications
 Connector type: FC optical connector
 Form factor: flat keystone module
 Housing colour: black
 Dimensions (W×D×H): 16.5 × 24 × 21.8 mm
 Mounting: snap-in keystone installation into compatible panels and plates
How to use
Insert the module into a compatible keystone opening by aligning the module with the cutout and pressing until it snaps into place. Connect the fiber by engaging the FC connector: ensure proper cleaning of endfaces before mating, then screw the FC coupling to secure the connection. For removal, unscrew the FC coupling and gently press the module release tabs (if present) to extract it from the panel or plate. Handle fiber ends and the connector with appropriate fiber-optic care to avoid contamination and damage.
Usage recommendations
Use appropriate fiber cleaning tools before mating FC connectors and avoid excessive bending of the fiber at the module interface. Install the keystone module into panels and plates that conform to keystone dimensions to ensure a secure fit. For permanent links, verify optical loss with suitable test equipment after installation.
