There are many different types of components used for communication. All these components fall under two categories, fiber optic active components and fiber optic passive components. The fiber passive components, which require no input power to function, include but are not limited to such devices as fiber optic connectors and fiber splicer, two simple components that join two pieces of fiber. While active device is any type of circuit component with the ability to electricity controlling electricity. The development of optical communication requires higher rate, larger capacity devices, while the cost is lower, which rely on photonic integrated circuit (PIC).
Main optical devices:
1). Optical passive devices, including optical fiber jumper, connector, plug, fixed attenuator, adapter, divider, isolator, coupler, dielectric film filter and optical fiber grating filter, optical switch, wavelength division multiplexing(WDM CWDM DWDM) and so on. These devices are generally used to split and combine signals, or alter them in various other manners.
2). Optical active devices, including optical sending and receiving module, amplifier, electrical adjustable attenuator.
Optical passive and active optical devices is also indispensable. Optical access network and the development of all-optical network, resulting in the development of optical passive devices unprecedented popular. Routine commonly used devices have reached a certain scale of the industry, the variety and the performance has been greatly expand and improve. The so-called optical passive means light energy consumption of the device, its wide range of different functions in optical communication systems and optical networks, the main role is: to connect the optical waveguide or optical path; control the direction of light propagation; to control the optical power distribution; between the control waveguide, between the device and the optical waveguide and devices, optical coupling; co-wave partial wave; the top and bottom of the optical channel and cross-connect.
Optics has been behind various enabling technologies to cope with the ever-increasing bandwidth demands at internet backbone level. Dense-wavelength-division-multiplexing (DWDM) allows concurrent transmissions of many channels of wide bandwidth data through a single fiber. The success of erbium-doped fiber amplifiers (EDFA) pushes the data regeneration distance longer and longer. The emerging massively parallel optical switches are revolutionizing all-optical communication networks. We are witnessing an era of renaissance of optics due to the communication infrastructure upgrade frenzy. High speed optics, once so prohibitively expensive that only long-haul communications was feasible, is being applied to ever-shorter distances, penetrating from metro-area to access and intra-computer interconnect networks. Bulk free-space optics is being miniaturized and integrated to serve critical missions to keep the pace of bandwidth booms. At the same time, the pace of developing wider bandwidth and more cost-effective solutions to sustain the explosive growth of bandwidth presents huge challenges and opportunities for optical scientists and engineers.
The rapid growth of WDM systems has attracted a great deal of attention. FiberStore supplies a full suite of passive optical devices based on its proven technology in optical fiber and PLC(Planar Lightwave Circuit) design and manufacture. We offer optical splitters (fused fiber & planar lightwave circuit splitter), as well as a variety of additional products.
