Important IEC 60794 Test Methods for Mechanical Tests on Optical Fiber Cables

This article deals with the recommended tests and their relevant IEC number. Often, people working in the fiber optic industry find it difficult to remember…

Electromagnetic Waves and their Application in Optical Communication

One of the biggest revolutions in human history was the start of the use of electromagnetic waves for modern communication. Modern communication means the exchange…

Tape Armoring of Fiber Optic Cables

Tape armoring is provided to ensure extra mechanical protection to the fiber optic cables. There are several types of tape materials that can be used for armor. Also, these tapes can be processed and applied in a variety of ways. We will see here a summary of tape armoring options, before that, let us see why tape armoring is preferable for some environments.

Environment Operating Requirements of Fiber Optic Closures

Fiber optic closures are used to protect optical fibers in a network. Fiber optic closures are integral part of the network that can be installed anywhere in the outside plant or inside plant. Fiber optic closures deployed in customer premises, Central office/telephone exchange, or other protected environments, shall meet minimal environmental protection criteria and fire-spread ratings.

Typical Requirements for a Fiber Optic Closure

Fiber optic closures that are called as joint closures are used to connect and store optical fibers of two cables safely either in the outside plant or indoor buildings. Fiber optic network operators specify the requirements for the joint closures according to the environment and application area. however, there are certain common requirements that every joint closure/splice closure shall meet. Those common requirements are discussed here.

Metallic and Non-Metallic Fiber Optic Closures

Fiber optic closure can be made of a metallic body and non-metallic body. Also, it could be a combination of metallic and non-metallic elements. In…

Fiber Optic Connector Types

ST is the most common fiber optic connector for multimode networks such as those used in buildings and campuses. ST connector has a long cylindrical…

Semiconductor Light Emitting Diodes and Laser Diodes

Both Semiconductor Light Emitting Diodes (LEDs) and Laser Diodes (LDs) are used in optical transmission as light sources. Semiconductor LEDs emit incoherent light, meaning the…

Coherent and Incoherent Light Sources

In Optical transmission, coherent light sources have clear advantages over incoherent light sources. The word Coherent means logical or consistent or clear. Incoherent is opposite…
