Ortronics 205KKF9GD-50E-A Lc OM4 Fiber Connector

Product Description

The ORTRONICS 205KKF9GD-50E-A is an LC-style fiber optic connector designed for use with OM4 multimode fiber at a 900um tight-buffer cable diameter. The keyed housing prevents mis-mating with non-keyed or incompatible adapters, a critical feature in high-density structured cabling environments where port identification and polarity management matter. This connector is used by low-voltage cabling technicians, network infrastructure installers, and data center technicians performing fiber termination and patching work. It ships as a single unit and is suited for field or shop termination applications.

This connector is appropriate for OM4 multimode fiber optic cabling installations in commercial, enterprise, and data center environments. OM4 fiber supports high-bandwidth applications at extended distances, making this connector a fit for backbone runs, horizontal cabling, and equipment room patching where 40G or 100G transmission is a consideration. The 900um buffer size is standard for indoor tight-buffered distribution cable. The keyed design is particularly useful in installations where lane or polarity identification is enforced at the connector level.

Key Features

• LC connector form factor for high-density fiber patching applications
• Compatible with OM4 multimode 50/125 fiber for high-bandwidth transmission
• 900um tight-buffer cable diameter accommodates standard indoor distribution fiber
• Keyed housing prevents accidental mis-mating and supports polarity management
• Single-unit packaging for precise inventory and field use

Compatibility

Designed as an OEM-style LC fiber optic connector for use with OM4 multimode 900um tight-buffered fiber optic cable in structured cabling systems.

Installation Notes

Installation should be performed by a qualified low-voltage cabling technician familiar with fiber optic termination procedures. Cleave and polish or pre-polished splice methods should follow manufacturer guidelines and applicable ANSI/TIA-568 standards. Inspect the ferrule end-face with a fiber inspection scope before mating to confirm proper polish and cleanliness. De-energize any active fiber ports and follow laser safety protocols before handling connected fiber ends.
