The Optical Fiber Connector Types: A Quick Guide

Understanding the different types of optical fiber connectors is crucial for ensuring efficient and reliable fiber optic communication. Here’s an easy guide to the key connector types, polishings, and colors:

Connector Types:

1️⃣ SC (Subscriber Connector): Widely used in data communication networks, offering easy push-pull operation.

2️⃣ LC (Lucent Connector): Small form factor connector that’s ideal for high-density connections.

3️⃣ FC (Ferrule Connector): Popular in industrial settings, known for its screw-type connection ensuring a secure fit.

4️⃣ ST (Straight Tip): Features a bayonet-style mount, commonly used in networking applications.

Polishing Types:

• PC (Physical Contact):
• Standard Polish: Minimizes back reflection, providing a stable connection.
• UPC (Ultra Physical Contact):
• Ultra Polish: Reduces reflection even further, ideal for high-speed networks.
• APC (Angled Physical Contact):
• Angled Polish: Offers the lowest reflection, perfect for high-performance applications.

Colors & Nomenclature:

• Connector Colors:
• Orange for 62.5/125 μm fiber
• Blue for 50/125 μm fiber
• Green for Single Mode APC fiber
• Yellow for Single Mode fiber
• Lime Green for OM5 fiber

Don’t forget the nomenclature when working with these connectors. For example, SC/PC refers to a Subscriber Connector with Physical Contact polish.

Understanding these basics can greatly improve your ability to work with and maintain fiber optic networks.
