Ortronics 205KNF9RA-09 Sc Upc OS2 Fiber Connector

Product Description

The ORTRONICS 205KNF9RA-09 is an SC UPC single-mode fiber optic connector designed for OS2 900-micrometer tight-buffered fiber. It uses the standard SC push-pull coupling mechanism and features a UPC (Ultra Physical Contact) polish for low back-reflection and low insertion loss. This connector is installed by low-voltage technicians and data cabling professionals working on structured cabling systems, telecom closets, and fiber distribution points. The blue color coding follows the TIA-568 convention for single-mode fiber identification, making polarity and fiber-type management straightforward during installation and maintenance.

This connector is suited for single-mode OS2 fiber runs in commercial and enterprise structured cabling environments. Typical applications include horizontal and backbone fiber cabling, fiber patch panel terminations, and equipment room interconnects where SC-style connectivity is specified. The 900-micrometer buffer retention makes it appropriate for tight-buffered fiber found in indoor plenum and riser cable assemblies. It is sold and installed as an individual connector unit.

Key Features

• SC UPC push-pull connector body for low back-reflection single-mode performance
• Designed for OS2 single-mode fiber with 900-micrometer tight buffer
• Blue color coding per TIA-568 single-mode fiber identification standard
• UPC polish provides reduced insertion loss versus PC polish
• Individual unit (each) packaging for field termination use

Compatibility

Designed as an OEM-style field-termination connector for OS2 single-mode 900-micrometer tight-buffered fiber optic cable applications using the standard SC connector form factor.

Installation Notes

Installation is performed by qualified low-voltage or fiber optic technicians following TIA-568 and manufacturer termination procedures. Proper fiber cleaving, epoxy or mechanical termination technique, and end-face polishing or inspection are required for acceptable insertion loss results. Always inspect the ferrule end-face with a fiber inspection microscope before mating to avoid contamination damage. Disconnect and cap all fiber ports before handling to protect end-faces.
