Single Mode Fiber Optic Cable Types

Single mode fiber optic cable.

Single mode fiber optic cable types.

Fiber optic connectors and cables are present in nearly every communications project that we might sell into be it a das installation or a base station with wireless backhaul you can be certain that fiber jumpers and cabling are being used somewhere in that network. With the increasing demand for greater capacity over long distance transmission single mode fiber optic cable is designed with various versions. Itu standards the itu has defined a series of recommendations that describe the geometrical properties and transmissive properties of multimode and single mode fiber optic cables. The different types of fiber optic cable vary in consistency and size but most are thinner than a human hair.

Fiber optic cables used in telecommunication are broadly categorized in two types multimode fiber and single mode fiber cables. In fiber optic communication a single mode optical fiber smf is an optical fiber designed to carry only a single mode of light the transverse mode modes are the possible solutions of the helmholtz equation for waves which is obtained by combining maxwell s equations and the boundary conditions. The exact distance does depend on what type of fiber optic cable is being used single mode or one of the various types of multimode. Single mode fiber is designed for long range transmissions.

There are 6 different categories of smfs. To read about the different types of fiber optic connectors click here. In iso iec 11801 and eia tia standards four types of multimode om1 om2 om3 om4 and two types of single. Single mode optical fiber is an optical fiber in which only the lowest order bound mode can propagate at the wavelength of interest typically 1300 to 1320nm.

Jump to single mode fiber page multi mode cable has a little bit bigger diameter with a common diameters in the 50 to 100 micron range for the light carry component in the us the most. Single mode fiber optic cables. The itu administers the commonly referenced single mode fiber standards documents g 652 through g 655 as required by telecom systems manufcturers and their customers. Because of this the number of light reflections created as the light passes through the core decreases lowering attenuation and creating the ability for the signal to travel further.

In the case of multi mode and single mode cables the glass used to make them is very pure as the refractive properties have to be high standard in order to conduct a data signal in this case made of light through a network. Fiber optic cable types multimode and single mode. Multimode fiber cable is prefixed with om and single mode fiber cable is prefixed with os. G652 g653 g654 g655 g656 and g657 among which g652 and g655 are two options frequently used in wdm.
