Ortronics 205KNF9EA-50T St Fiber Connector OM3

Product Description

The ORTRONICS 205KNF9EA-50T is an ST-style fiber optic connector designed for terminating 900-micron buffered OM3 multimode fiber. The aqua color coding identifies it as an OM3-rated component, following standard industry color conventions for multimode fiber infrastructure. This connector is intended for use in structured cabling installations where reliable multimode fiber termination is required. Network installers and low-voltage technicians use this connector when building or maintaining fiber optic runs in commercial and data center environments. The ST bayonet-style coupling provides a secure, twist-lock mating interface suitable for patch panels, wall plates, and fiber distribution hardware.

This connector is suited for 900-micron tight-buffered OM3 multimode fiber installations in commercial buildings, campus networks, and data centers. It fits into structured cabling systems where ST-style fiber ports are specified. Typical applications include horizontal and backbone fiber runs terminated at patch panels, outlets, or active equipment with ST ports. The aqua jacket color helps technicians quickly identify OM3 fiber segments during installation and troubleshooting.

Compatibility

Designed for termination on 900-micron tight-buffered OM3 multimode fiber; compatible with ST-style fiber optic ports, patch panels, and adapter plates that accept ST connectors.

Installation Notes

Installation should be performed by a qualified low-voltage technician or structured cabling installer familiar with fiber optic termination procedures. Proper cleaving and polishing tools are required to achieve acceptable insertion loss at the fiber end face. Follow TIA-568 and manufacturer termination guidelines when preparing and seating the fiber. Inspect the ferrule end face with an appropriate fiber inspection scope before mating to avoid damage to connected equipment.
