An optical circulator is a small yet powerful device used in optical communication systems. The device is typically used to separate optical signals that (in an optical fiber) travel in opposite directions.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\" wp-image-857 aligncenter\" src=\"http:\/\/www.dkphotonics.com\/blog\/wp-content\/uploads\/optical-circulator.jpg\" alt=\"\" width=\"547\" height=\"292\" srcset=\"https:\/\/www.dkphotonics.com\/blog\/wp-content\/uploads\/optical-circulator.jpg 500w, https:\/\/www.dkphotonics.com\/blog\/wp-content\/uploads\/optical-circulator-300x160.jpg 300w\" sizes=\"auto, (max-width: 547px) 100vw, 547px\" \/><\/p>\n<p style=\"text-align: justify;\"><u>Functioning Principle and Components<\/u><\/p>\n<p style=\"text-align: justify;\">Optical circulators usually consist of a polarizing beam splitter, Faraday rotator, reflector prism, birefringent blocks, and a retardation plate. The functioning of an <strong><a href=\"http:\/\/www.dkphotonics.com\/product\/Fiber-Optical-Circulator.html\">optical circulator<\/a><\/strong> is a little similar to optical isolator. A light which travels in one direction right through the Faraday rotator will have its polarization rotated in one specific direction. A light that enters the rotator from the opposite direction will have its phases rotated in the opposite direction (sometimes may depend upon the propagation direction of the light).<\/p>\n<p style=\"text-align: justify;\">In other words, light always rotates in one direction in accordance with the rotator regardless of its traveling direction.<\/p>\n<p style=\"text-align: justify;\">Three-port optical circulator is widely used so let\u2019s discuss that first. A signal in a three-port optical circulator is transmitted from 1st port to 2nd port where another signal is transmitted from 2nd to 3rd and additionally, a third signal can also be transmitted from 3rd to 1st.<\/p>\n<p style=\"text-align: justify;\"><strong>Types<\/strong><\/p>\n<p style=\"text-align: justify;\"><u>As per the Polarization Characteristics<\/u><\/p>\n<p style=\"text-align: justify;\">If we talk about the characteristics based on the optical circulator\u2019s polarization capabilities, they can be divided into two major types:<\/p>\n<p style=\"text-align: justify;\">PM &#8211; Polarization Maintaining<\/p>\n<p style=\"text-align: justify;\">PI &#8211; Polarization Insensitive<\/p>\n<p style=\"text-align: justify;\">Each PM optical circulator typically comes in the market with a polarization maintaining fiber which makes it an ideal component for applications where it is necessary to maintain polarization, for example, Raman pump applications, 40Gbps systems, etc.<\/p>\n<p style=\"text-align: justify;\">Polarization insensitive optical circulator is a small lightwave component which delivers high-performance functioning. The component comes in the market having features like low insertion loss, high isolation, high stability and reliability, and low polarization-dependent loss (PDL).<\/p>\n<p style=\"text-align: justify;\">It is high in demand in combination with fiber gratings and other reflective components in close-packed wavelength-division multiplexing (DWDM) systems, high-speed systems and bi-direction communication systems.<\/p>\n<p style=\"text-align: justify;\"><u>As per the number of ports availability<\/u><\/p>\n<p style=\"text-align: justify;\">Optical circulators fall into three main types when it comes to the number of ports:<\/p>\n<p style=\"text-align: justify;\">3-port<\/p>\n<p style=\"text-align: justify;\">4-port<\/p>\n<p style=\"text-align: justify;\">6-port<\/p>\n<p style=\"text-align: justify;\">3-port and 4-port optical circulators are commonly used way more than the 6-port optical circulations. In such circulators, optical light that is transmitted from any port can easily be redirected to any other port, regardless of the port-type.<\/p>\n<p style=\"text-align: justify;\">An optical circulator is very commonly applied in a long list of applications within a fiber communication system. In modern optical communication systems, the optical circulator is usually used for wavelength division multiplexing networks, optical time domain reflectometers, fiber amplifier systems, bi-directional transmissions, etc.<\/p>\n<p style=\"text-align: justify;\">With primary characteristics such as high isolation, low crosstalk, low insertion loss, and large bandwidth, the optical circulator can also become an in-built component of the same device as transmitters, amplifiers, and receivers.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>To fulfill the requirement of communication efficiency, network technicians generally use optical circulator in a fiber optic system as it reduces the loss of light.
