VOA Variable optical attenuator (VOA) is a device that allows for the adjustment of the attenuation level of an optical signal as needed. Its main function is to precisely control the intensity of the light signal being transmitted by varying the mechanisms of absorption, reflection, or other attenuation methods. VOAs are widely used in fiber optic communication systems, fiber optic sensing, equipment testing, and calibration.

Mechanical optical switch: technological pioneer for precise control of optical paths Mechanical optical switch is a device that uses the principle of mechanical part movement and optical part reflection and transmission of light to achieve switch control. It cleverly combines mechanical structure with optical characteristics, and achieves precise switching of optical signal paths by controlling the position changes of reflectors or transmissive elements. Mechanical optical switches are mainly composed of light sources, optical fibers, reflectors, detectors, and precise mechanical structures. These components work together to ensure efficient transmission and precise control of optical signals in complex networks. #xhphotoelectric #opticalswitch #Data #fiber #optics #photonics #NetworkSwitch Read more https://lnkd.in/g_FEgeCq

MEMS VOA MEMSVOA includes reflective VOA and diffractive VOA. Reflective VOA is a micro-mirror made on a silicon base. Light enters through one end of the dual-core collimator and is incident on the micro-reflector at a certain angle. When a voltage is applied, the micro-reflector is twisted under the action of static electricity, the inclination angle changes, and the incident angle of the incident light changes. After the light is reflected, The energy cannot be completely coupled into the other end of the dual-core collimator to achieve the purpose of adjusting the light intensity; when no voltage is applied, the micro-reflector is in a horizontal state, and the energy after light reflection is fully coupled into the other end of the dual-core collimator. Diffractive VOA is based on dynamic diffraction grating technology. When a voltage is applied, the positions of the movable grating bars at the same intervals move downward under the action of electrostatic force to produce a diffraction grating effect. The voltage adjustment is used to control the first-order diffracted light to achieve the purpose of adjusting the attenuation of the optical signal.

How to connect the three ports of the fiber optic circulator? The fiber optic circulator is a multi-port device that sequentially transmits the incident wave entering any one of its ports to the next port in a direction determined by the static bias magnetic field. For example, if a signal is input from port 1, the signal can only be output from port 2. Similarly, a signal input from port 2 can only be output from port 3, and so on. The signal transmission direction of the fiber optic circulator is irreversible and can only guide the optical signal from one port to another in one direction at a time. For example, a three-port circulator optical signal must travel from port 1 to port 2 and then to port 3. In practical applications, fiber optic circulators are often used in laser communication systems, such as duplex laser communication at fixed points on the ground. This system is based on the one-way transmission characteristics of the optical fiber circulator, and performs two-way transmission of light emission and reception on the same optical fiber to realize the two-way communication function of laser transceiver. #xhphotoelectric #opticalswitch #optics #communications #photonics #fiber #data #NetworkSwitch Read more https://lnkd.in/gKHeubzA

 OLP module XH-OLP-S1-1-M dual-fiber optical fiber disconnection automatic switching protection module is mainly used for real-time failover protection of optical networks. In the optical network signal link installed with the XH-OLP-S1-1-M module, when one of the technical indicators of the main fiber dual-fiber channel optical signal exceeds the threshold (such as the threshold set by the power drop, including ), the XH-OLP-S1-1-M module automatically switches the signal from the faulty channel to the standby channel to realize the real-time link protection of the optical signal channel. Users can set manual switching optical path or automatic switching optical path according to their needs. The optical protection module realizes dual-fiber switching by the cooperation of two modules, so when one module switches the backup fiber, the other module will also automatically switch to the backup fiber; In case of failure, the main fiber will be switched automatically. The module supports two kinds of communication interfaces: the large network (RJ45) and the serial port (RS-232). Users can realize remote control and local control through the Ethernet interface or the serial port. #xhphotoeletric #fiber #OLP #photonics #optics #communications #OLT #fibra #fotónica #óptica #comunicaciones #섬유 #포토닉스 #광학 #통신 Read more https://lnkd.in/gm9rWHb4

C+L band three-port SM fiber optic circulator XIONGHUA Photonics’ three-port fiber optic circulator is a multi-port non-reciprocal optical device in which light can only travel in one direction. If the signal is input from port 1, it will be output from port 2; if the signal is input from port 2, it will be output from port 3, and its output loss is very small; when the light is input from port 2, the loss when output from port 1 is very large. Similarly, when light is input from port 3, the loss when output from ports 1 and 2 is also very large. #xhphotoelectric #fiber #Instrumentation #sensing #optics Read more https://lnkd.in/gDdA4w4m
