The role of Common Optical Attenuator Types
Fiber attenuators are not as popular as fiber pigtails or patch cords. However, It is quite necessary in fiber optic connections. There are still some Common Optical Attenuator Types on the market.
Before we learn of the Common Optical Attenuator Types, We need learn below details about what is Fiber optic attenuator.
Fiber optic attenuator is a passive device used to debug light power performance in optical communication system, debug the calibration calibration of optical fiber instrument, and attenuation of optical fiber signal. The product is made from the attenuation fiber doped with metal ions, which can adjust the optical power to the required level. Generally, the optical attenuators are used in single-mode long-haul applications to prevent optical overload at the receiver.
Principle of optical fiber attenuator
Attenuators are like sunglasses, which protect your eyes from strong light by absorbing extra light energy. Optical fiber attenuators can protect the optical fiber by working at specific wavelengths, like sunglasses. The standard of a good fiber attenuator is to replace the reflective fiber by absorbing additional fibers. Because in optical fiber communication, it is necessary to use lower optical power without damaging the attenuator of optical fiber.
Listings of Common Optical Attenuator Types
Optical attenuators can take a number of different forms and are typically classified as fixed or variable attenuators. What’s more, they can be classified as LC, SC, ST, FC, MU, E2000 etc. according to the different types of connectors. By the way, attenuator is divided into female to female and female to male. The attenuator not only has different optional type, such as apc, upc or pc, but also have singlemode and multimode.
SC fiber optic attenuator
SC fiber optic attenuator Common Optical Attenuator Types
SC fiber attenuator: applied to the SC fiber interface, it looks very similar to the RJ-45 interface, but the SC interface is flatter, and its distinct difference is the touch of the inside. If it is 8 thin copper touch slices, it is the RJ-45 interface, and if a copper column is a SC fiber interface.
Various type of SC optical fiber attenuator we offer is both SC UPC ,SC APC and SC PC fiber attenuators. Attenuation values range from 1dB to 30dB.Operating wavelength typical is 1310nm and 1550nm,which fit for single mode fiber applications. But also have wavelength is 850 nm, which fit for multimode fiber applications.
LC fiber optic attenuator
lc fiber optic attenuator Common Optical Attenuator Types
The LC fiber attenuator is applied to the LC optical fiber interface to connect the connector of the SFP module. It is made of a convenient modular latch (RJ) latch mechanism.
The most commonly used type is female to male plug type fiber optic attenuator, it has the optical fiber connector at one side and the other side is a female type fiber optic adapter, fiber optic attenuator name is based on the connector type and the attenuation level. LC 5dB fiber optic attenuator means this attenuator uses LC fiber optic connector and it can reduce the optical fiber power level by 5dB. Commonly used attenuation range is from 1dB to 30dB.
ST fiber optic attenuator
st fiber optic attenuator Common Optical Attenuator Types
Applied to ST optical fiber interface, commonly used in optical fiber distribution rack, the shell is round, fastening way is screw buckle. Have singlemode and multimode, which wavelengths are respectively 1330nm and 850nm.
FC fiber optic attenuator
fc fiber optic attenuator Common Optical Attenuator Types
Applied to FC optical fiber interface, external reinforcement is made of metal sleeve and fastening way is screw buckle. The attenuation value of our attenuator is more accurate and the price is more favorable.
