The Optical Fiber Connector Types: A Quick Guide

[dangquangminh]

🔷 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.
