Fiber Optic Cable Pairing Process

How fiber cable pairs are made

Internet fiber cable pair connections, also known as fiber optic connections, are typically made using connectors specifically designed for optical fiber.

These connectors ensure precise alignment and minimize signal loss in the transmission of light through fiber cables.  The process of making a fiber cable pair connection involves the following steps:

Fiber preparation first: Before connecting, both ends of the fiber cable must be prepared.  This involves stripping the protective coating from the ends of the fibers to expose the bare glass fibers.

Cleaving: The next step is to cleave or cut the fibers with a special tool called a cleaver.  Cleaving ensures a clean, flat end face for optimal light transmission.

Connector Assembly: The connectors are then attached to the cleaved fiber ends.  Some connectors come in different types, such as SC (Subscriber Connector), LC (Lucent Connector), ST (Straight Tip), or FC (Fiber Connector).  Each connector has its own specific design and mechanism for securing the fiber.

Polishing: After connecting the connectors, the fiber ends must be polished to achieve a smooth, flat surface.  Polishing removes any irregularities or imperfections created during the cleaving process and ensures better light transmission.

Inspection and Cleaning: Once the connectors are polished, the fiber end faces are inspected using a special microscope to check for any defects or contamination.  If necessary, they are cleaned using lint-free wipes and approved cleaning solutions to remove dust, oil or other contaminants.

Fusion Splicing: In some cases, instead of using connectors, fiber cables are joined by fusion splicing.  Fusion splicing involves aligning and fusing the bare fiber ends together using an electric arc or laser.  This creates a permanent and low-loss connection between the fibers.

Testing: After making the connection, fiber pairs are tested to ensure proper signal transmission and minimum loss.  Various test methods, such as optical time-domain reflectometry (OTDR) or power meter testing, can be used to measure signal quality, loss, and reflection.

It is important to note that the specific methods and equipment used to make fiber cable pairs may vary depending on the equipment, standards, and industry practices followed by the technicians or organizations involved.
