They are differentiated by being categorized into standardized types, including SC, FC, LC and others. The SMA designation is utilized for higher power applications were fiber-optic cables have to be joined. These connectors are very precise and they provide an exceptionally strong connection. Even when connectors are utilized that make it easy to terminate and install a connectors, there is a very involved process that must be undertaken involving cleaning off the fibers, joining them correctly and so forth. These are generally devices that require much more precision and skill to use than a standard telecom connector.

How do Fiber Optic Connectors work?

Fiber-optic connectors consist of a metal cylinder and a sleeve. These connectors are often designed to lock together very securely, often with the use of a latch or a threaded connector. The fiber-optic cable is threaded through the body of the connector and adhesive is used to secure the fiber in place. Another device utilized to eliminate stress on the fiber-optic cable is installed in the rear of the connector. In order to properly join the lines, the ends of the fiber have to be polished in a very specific way that ensures a good connection.

Some fiber-optic cables are designed to be spliced together more easily than was possible in the past. These fiber-optic cables typically have pre-polished surfaces and some of them include a gel in the line that makes connecting lines together much easier.

What are Fiber Optic Kits?

Because working with fiber-optic cable is such a complicated endeavor, there are kits available that come with everything that is required to perform various tasks on fiber-optic lines. Fiber optic kits generally include all of the tools needed to perform a specific repair or to test a line. For example, termination kits come with everything required to successfully terminate a fiber-optic line, from the polishing tool to the stripper used to clean off the lines.

Evaluation kits make it easy for technicians to get an idea of whether or not a fiber-optic line is in good condition. They contain all the necessary tools and help technicians to avoid situations where they figure out that they need one more vital tool and they don've it on hand.

What are Fiber Optic Patch Panels?

Fiber-optic patch panels allow many different lines to be joined together into a single system. These devices can be mounted in various locations, depending upon their design.
