Fiber Coupler

Your network’s performance could hinge on fiber coupler performance. These critical components are often overlooked when upgrading existing networks (or installing new networks) but shouldn’t be. Primus Cable carries an extensive selection of advanced, affordable fiber optic coupler products to address your network’s communication needs.

A fiber optic adapter is a device used in optical fiber systems with one or more input fibers and one or several output fibers.

Light entering an input fiber can appear at one or more outputs and its power distribution potentially depending on the wavelength and polarization. Such couplers can be fabricated in different ways, for example by thermally fusing fibers so that their cores get into intimate contact. If all involved fibers are single-mode (supporting only a single mode per polarization direction for a given wavelength), there are certain physical restrictions on the performance of the coupler. In particular, it is not possible to combine two or more inputs of the same optical frequency into one single-polarization output without significant excess losses. However, such a restriction does not occur for different input wavelengths: there are couplers which can combine two inputs at different wavelengths into one output without exhibiting significant losses. In this case, a fiber optic adapter is utilized.

A wavelength-sensitive fiber optic adapter is used as a multiplexer in wavelength-division multiplexing (WDM) telecom systems to combine several input channels with different wavelengths, or to separate channels.

A fiber coupler can also help increase the distance (range) of your fiber optic patch cables. This is a crucial consideration for network expansion and general upgrades.
