LGC-SH4A313 - HONDA CONNECTORS INC

An optical fiber cords is constructed by covering the optical fiber core with the buffer around the optical fiber being covered with

the primary coat as illustrated below. Also, this optical fiber core is provided with Kevler fiber reinforced plastic (a tensile

strength material) being covered with the jacket around.

Optical Fiber Cords

An Example of the Constructions of Optical Fiber Cords

An optical fiber consists of a core and a cladding. Light passes through the core while it is being reflected by the cladding as

illustrated below.

Sort of Optical Fibers

The optical fiber modes are shown in the following figures.

Core and cladding of optical fiber

Wavelengths commonly used as light source for silica optical fiber are 0.85, 1.31, or 1.55 μm.

Categorized by mode and wavelength, the optical fiber can be shown as follows.

The secondary sheath diameters are sorted into ø2mm and ø2.8mm.

Certain cores are not covered with the secondary sheath.

Optical fibers can be connected to each other by the permanent connection method or removable connector connection

method. The optical fiber connection is subjected to various connection loss factors, such as the axial misalignment of fibers,

angular deviations, space deviations, incomplete end faces, etc. Optical fiber connectors are required to have highly precise

sizes to coincide the optical fiber cores with each other accurately. Optical fiber connectors are indispensable for connecting

between optical fibers and various devices as the components of optical communication systems.

●Major polishing of optical fiber connectors

The standard values of the insertion loss and return loss depend upon the polishing and mode.
