## Long description

DELOCK 87121 is a flat keystone module with an SC simplex adapter designed for fiber optic panel and faceplate installations. The module's compact dimensions — 16.5 × 27.4 × 21.9 mm — conform to standard keystone openings, allowing snap-in mounting into keystone patch panels, face plates or surface-mount boxes. Supplied individually in a polybag, the module is available in a green/black housing and provides a single SC female port suitable for single-mode fiber connections with low insertion loss.
Advantages
The flat, low-profile design saves space in densely populated panels and wall plates while maintaining compatibility with standard keystone cutouts. The integrated SC female connector with dust protection supports single-mode fiber termination and ensures insertion loss below 0.2 dB, which helps preserve signal integrity. The product is supplied as a single unit for flexible, on-demand installation and replacement.
Suitable for
 Keystone patch panels for fiber optic infrastructure
 Wall plates and faceplates in offices or data closets
 Surface-mount boxes and small enclosures
 Point-to-point single-mode fiber extension and connector panels

How to use
Prepare the patch panel, faceplate or surface-mount box by ensuring a compatible keystone opening is available. Align the module with the opening and press until it snaps into place; no additional tools are required for mounting. Connect a single-mode fiber terminated with an SC male connector into the module's SC female port. If necessary, attach or replace dust covers when the connector is not in use to protect the ferrule from contamination.
Usage recommendations
For best performance, use this SC keystone module with single-mode fiber cables and maintain clean connector endfaces. Inspect and, if needed, clean connectors with appropriate fiber-optic cleaning tools before mating. Avoid excessive bending of fiber near the connector and secure cables to reduce strain on the module. Store unused modules in their packaging to keep dust covers and alignment intact.
