3.1. LC vs SC connector

Size and density : SC connector is bigger, which limits its use in high density installations. On the other hand, the LC connector is smaller, ideal for modern environments requiring more connections in less space.

Ease of use : The SC uses a simple push-pull system, but its larger format may be less practical in tight spaces. The L.C., with its small design, is more suitable for compact installations.

Applications : SC is often used in installations with lower density requirements, while LC is preferred in high speed and high density networks, like in data centers.

3.2. LC vs ST connector

Conception : The ST connector uses a bayonet mechanism, more robust, but less practical than the LC clip for frequent installations. It is common in industrial networks, while LC is more suitable for high-speed networks.

Optical performance : The LC offers better transmission performance thanks to its optimized design, ideal for high-speed networks, unlike the ST.

Applications : The ST is used in industrial environments, while LC is the preferred choice for modern high-density, high-bandwidth networks.

3.3. Why LC has become a modern standard

The LC connector has become a standard due to several advantages :

Compact size : It allows you to connect more ports in a smaller space, what is essential in modern installations.

Haute performance : The LC guarantees stable transmission and clear signals thanks to its precision ferrule.

Adapted to modern networks : It meets the needs of high-speed networks, such as those used in data centers and FTTH applications.

Compatibility : LC is widely used by manufacturers, which ensures high compatibility with various equipment.

4. Installation et maintenance

4.1. Installation procedure

Installing the LC connector is simple, but it requires a certain precision. Here are the key steps :

Preparing the optical fiber : Start by cutting the optical fiber to the appropriate length. Ensuite, carefully strip the fiber cladding to expose the core.

Insertion into LC connector : Insert the fiber into the LC connector, ensuring the fiber is correctly aligned in the ferrule to ensure optimal transmission.

Fiber fixation : Use an adhesive or resin to fix the fiber into the connector and make sure it is stable.

Verification : Check the correct insertion of the fiber into the LC connector and ensure it is properly locked and secure.

It is essential to follow good installation practices to avoid poor connections and signal loss. LC connectors can be installed in specific patch panels or modules.

4.2. Maintenance and cleaning

To ensure optimal performance of the LC connector, regular maintenance is necessary. Here are the key steps for maintenance and cleaning :
