Fiber optic connector R

Page Content

The Fiber Optic Connector R refers to the FC/PC Type R (narrow key) connector, commonly used for single-mode and multi-mode fiber applications.

Overview

The FC/PC Type R connector is a screw-in fiber optic connector designed for high stability and precise alignment of optical fibers. It is widely used in single-mode fiber networks but can also be applied to multi-mode fibers. The Type R designation indicates a narrow key with a width of approximately 2 mm, which prevents fiber rotation when the connector is screwed into the receptacle, ensuring consistent optical performance .

Key Specifications

  • Ferrule Diameter: 2.5 mm
  • Bore Tolerance: 0/+1 µm
  • Key Width: Narrow key 2 mm (Type R), with a standard range of 1.97 mm to 2.02 mm
  • Crimp Options: Available for 1.6, 2.0, 2.5, and 3.0 mm fiber optic cables
  • Connector Types: FC/PC and FC/APC, with PC (Physical Contact) or APC (Angled Physical Contact) polishing for low insertion loss and return loss
  • Boot Options: 3 mm 90° boot available; other colors and configurations can be customized

Features and Advantages

  • High Mechanical Stability: The screw-in design and spring-loaded ferrule provide strong contact and mechanical isolation, making it suitable for environments with vibration or movement.
  • Precision Alignment: The ferrule and keying system ensure accurate fiber alignment, minimizing insertion loss and back reflection.
  • Flexibility: Crimp and pre-assembled options allow for easy integration into patch cords, pigtails, and custom cable assemblies.
  • Durability: Designed for repeated connections and disconnections without significant performance degradation .

Applications

The FC/PC Type R connector is used in:

  • Telecommunications and Data Centers: For single-mode fiber links requiring high precision and low return loss.
  • Industrial Automation: Where robust and vibration-resistant connections are needed.
  • Medical and Sensor Technology: For reliable optical signal transmission in sensitive equipment.
  • High-Density Fiber Networks: Compatible with modular systems and patch panels for flexible network configurations .

Summary

The Fiber Optic Connector R (FC/PC Type R) is a reliable, high-precision connector suitable for single-mode and multi-mode fiber applications. Its narrow key design, robust ferrule, and flexible crimping options make it ideal for environments requiring mechanical stability, low insertion loss, and repeatable connections. It is widely used in telecommunications, industrial, and medical applications, providing a durable and precise solution for optical fiber networks .
