Signamax CMK-LCA-BK — LC Singlemode APC Keystone Insert, Black

The Signamax CMK-LCA-BK is a keystone-format LC singlemode APC fiber insert engineered to provide a compact, panel- and wallplate-compatible fiber coupling solution. Its LC APC interface supports singlemode connections where reduced back-reflection is required, improving signal integrity in sensitive links. The keystone form factor installs into standard keystone openings for fast mounting in wallplates, patch panels, and surface-mount boxes. Designed for consistent ferrule alignment, the insert simplifies field termination and pre-terminated cable mating while keeping port density high. Finished in black for discreet installation and visual identification, it integrates cleanly into commercial and residential wiring assemblies. This insert is a practical choice for installers, integrators, and maintenance teams needing reliable LC APC couplings in a keystone format.
