Introduction to Fiber Optic Connectors and Cables

Overview of Presenters

• The presenters, Vinicio Muela and Calvo Piña, are students from the Escuela Politécnica Nacional studying telecommunications in their eighth semester. They introduce a video on fiber optic connectors and cables.

Importance of Fiber Optic Connectors

• Fiber optic connectors facilitate easy coupling between transmission and reception elements, making them crucial for optical networks.

• There is a variety of fiber optic connectors; understanding connector acronyms helps identify types and polishing methods.

Types of Connector Polishing

Connector Types Explained

• The SC APC connector is highlighted as commonly used in home internet services, indicating its type and polish.

• Two main polishing types are discussed: APC (green color with an 8-degree angle polish) and UPC (blue color with flat polish), affecting light reflection and return loss.

Applications Based on Connector Type

• SC APC connectors are preferred for sensitive applications requiring high precision due to lower return loss.

• For less sensitive applications, the SSVC connector can be effective.

Main Types of Connectors Used in Optical Networks

Key Connector Types

• Four primary types of connectors are identified:

• LC: Features a 1.25mm ferrule with low insertion loss.

• SC: Popular design allowing versatile connections with a 2.5mm ferrule.

• ST: Bayonet-style design for easy alignment using push-and-twist mechanism.

• FS: Screw-type design ensuring firm connection.

Components of Fiber Optic Connectors

Parts Breakdown

• FC connectors consist of several parts including sleeve, crimp tube, spacer, body, ferrule, and cap.

• ST connectors include protective tube components along with their round body structure.

Understanding Fiber Optic Cables

Modes of Fiber Optics

• Two modes exist for fiber optics:

• Multimode: Allows multiple light paths through a larger core diameter; suitable for short-distance applications like LAN networks.

• Single-mode: Only one light path through a smaller core; ideal for long-distance applications needing high precision.

Types of Fiber Optic Cables

• Three cable types are mentioned:

• Pascor Cable: Designed solely for indoor use due to its fragility.

• Drop Cable: Used to connect from poles to final locations (last mile), typically black with up to four fibers inside.

Understanding ADSS Fiber Optic Cables

Overview of ADSS Fiber Optic Cables

• ADSS Cable Structure: The ADSS (All-Dielectric Self-Supporting) fiber optic cable features a steel wire that protects the fiber and provides support for aerial installations. This design allows it to bear its own weight without additional support.

• Composition and Advantages: The SS fiber optic consists of one or more optical fibers coated with a weather-resistant plastic layer. This type is lighter and easier to install compared to internally reinforced cables, offering greater tensile strength.

• Fiber Count Options: Common configurations for ADSS cables include 12, 24, or 48 optical fibers, making them suitable for high-capacity communication systems.

Conclusion and Educational Value

• Summary of Key Topics: The discussion covered various types of connectors, polishing methods, and different modes of optical fibers. The aim was to provide an interactive and educational experience.
