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

Product Description

The ORTRONICS 205KKF9GD-50E-J is an LC-style fiber optic connector designed for use with 900-micron buffered OM4 multimode fiber. It features a keyed housing to prevent mismatched mating and ensure correct polarity alignment during termination. This connector is used in structured cabling installations where high-density fiber patching and low insertion loss are required. Network and low-voltage cabling technicians install this type of connector in data centers, telecommunications rooms, and enterprise LAN environments. The small form-factor LC design makes it suitable for high-density patch panels and fiber distribution hardware.

This connector is appropriate for OM4 multimode fiber cabling systems operating at 850nm and 1300nm wavelengths. It is used in horizontal and backbone cabling runs where 40G and 100G Ethernet applications demand low-loss terminations. The 900-micron tight-buffer construction suits indoor plenum and riser cable assemblies. The keyed housing is particularly useful in installations where polarity management is critical, such as MPO-to-LC breakout configurations and duplex patch cord assemblies.

Key Features

• LC connector form factor for high-density fiber installations
• Compatible with OM4 50/125-micron multimode fiber
• 900-micron buffered fiber design for tight-buffer indoor cable
• Keyed housing prevents incorrect mating and maintains polarity
• Sold individually as a single connector unit

Compatibility

Designed as an OEM-style connector for use with 900-micron buffered OM4 multimode fiber in structured cabling and fiber distribution systems.

Installation Notes

Installation of fiber optic connectors should be performed by a qualified low-voltage or registered communications distribution designer technician. Proper fiber cleaving, polishing, and inspection tools are required to achieve acceptable insertion loss values. All active equipment should be powered down and fiber circuits should be verified dark before termination work begins. Follow TIA-568 and applicable local codes for fiber handling, routing, and connector installation procedures.
