An optical fiber multiplexer is a device that processes two or more optical signals through a single optical fiber in order to increase the amount of information that can be transmitted through the network. The light wavelength is a narrow beam bounced by a reflective light pipe (sometimes a long-distance reflective light pipe) to provide instantaneous electronic signals for signal processing at the speed of light. The multiplexer works by using different technologies and light source technologies to increase the transmission capacity of the optical fiber. When the signal reaches its destination, the multiplexer separates the data stream. The use of multiplexers can also make data transmission farther, safer, and less electromagnetic and radio frequency interference.
Wavelength division multiplexing allocates different wavelengths or parts of the electromagnetic spectrum for different information streams. Also known as a multiplexer, the fiber multiplexer compresses more information through the optical network path, thereby saving time and cost. By changing the schedule or cycle of each transmission. Time division multiplexing (TDM) combines multiple signals by quickly alternating between multiple signals so that only one signal is transmitted at any given time. Statistical Time Division Multiplexing (STDM) allocates a specific time slot for each signal to optimize bandwidth usage. Further techniques include the division of wavelength and frequency.
Fiber optic multiplexer. Wavelength division multiplexing (WDM) utilizes the total available passband of optical fiber. It allocates individual information streams of different wavelengths, or parts of the electromagnetic spectrum. Similarly, frequency division multiplexing (FDM) assigns different frequencies to each signal. The carrier frequency contains the signal, and the unused guard frequency provides buffering to reduce interference. This helps to minimize sound and visual noise, and maintain the integrity of the original signal throughout the network. Fiber multiplexing technology provides services for single-mode and multi-mode fiber with multi-channel rack-mounted or independent units. This allows mixed channels of different configurations to be used in a series of interface combinations. These devices provide stronger reliable transmission in areas with a lot of electromagnetic, radio frequency or lightning interference. As technology advances and the demand for information grows to meet the capacity of existing networks, devices like fiber multiplexers reduce the need to upgrade the fiber infrastructure itself. The multiplexer allows the configuration of new transmission protocols by increasing the wavelength or frequency of the optical signal. By upgrading repeaters and terminal equipment, the existing network transmission capacity can be expanded with demand. Optical fiber multiplexing technology is widely used in cellular operators, Internet service providers, public utilities and enterprises, expanding the scope of telecommunications technology And power. The network management system allows system service and maintenance, and provides security, fault management, and system configuration. Due to the advantages of low cost and long service life, the current optical fiber network has been improved in multiplexing technology, and may well provide light-speed data transmission in the future.
