Fiber Optic Attenuators

A fiber attenuator is an optical device that reduces the energy of a light signal.Used for the attenuation of input optical power, avoiding distortion caused by the input optical power. As a passive device, the fiber attenuator is used for debugging optical power performance in optical communication system, calibration correction of optical fiber instrument, and attenuation of optical fiber signal. The product is made of decaying fiber mixed with metal ions, which adjusts the optical power to the desired level. The fiber attenuator test system has the characteristics of high attenuation accuracy, low additional loss and good stability. The fiber attenuator is mainly used in: optical communication system, fiber optic CATV, high-power optical device measurement, for the attenuation of input optical power, avoiding the distortion caused by the optical receiver due to the strong input optical power.

SC/ST/FC/LC Attenuators

By port type, you can categorize fiber optic attenuators in several categories as follows:
SC fiber attenuator: applied to the SC fiber interface, it looks very similar to the RJ-45 interface, but the SC interface looks more flat, the obvious difference is the inside of the touch, if it is 8 thin copper taps, is the RJ-45 interface, if it is a copper column is the SC fiber interface. LC Fiber Attenuator: A connector for the LC fiber interface that connects the SFP module and is made of a convenient modular jack (RJ) latch mechanism. FC fiber attenuator: applied to FC fiber interface, the external reinforcement method is to use metal sleeve, fastening mode for screw buckle. Generally used on the ODF side. ST fiber attenuator: used in The ST fiber interface, often used in fiber optic wiring rack, the shell is round, fastening mode is screw buckle. There are female to male attenuators and inline cable attenuators.

Attenuator Applications

Fiber attenuator is a very important fiber optic passive device, with the development of optical communication industry was born. The fiber attenuator can reduce the optical signal and is used to attenuate the input optical power, avoiding the distortion of the optical receiver due to the high input power. With the development of optical communication industry and the improvement of the level of process manufacturing, the loss of optical fiber optic cable, connector and other optical fiber devices is decreasing, less than the amount of attenuation of the design, which may lead to the optical receiver received a larger optical power, more than its tolerance range, the situation of saturation distortion. Therefore, in order to reduce the signal received by the optical receiver, a light attenuator is required to control the optical power within a certain range.

Fiber Optic Attenuators from Professional China Manufacturer

In-line fiber attenuators provide optical communication devices that provide specific attenuation slots based on the different needs of different projects. The in-line fiber attenuator can be applied to a variety of fiber transmission lines for pre-set light intensity attenuation. This fiber attenuator is mainly used in fiber optic communication network, fiber-optic CATV network, fiber-optic data network and fiber-optic test system. The attenuator value of the in-line fiber attenuator is high with high precision, low additional loss, and better stability than other types, while its attenuation value can be adjusted according to its needs.

Fixed fiber attenuators are more like adapters, which are mainly used in fiber optic communication systems, fiber optic CATV and high-power optical device measurement. Mainly through the way of flange to use, FC, SC, ST and LC all kinds of connector jumpers can be used, it is very convenient to install, easy to use, by many users love.

Female to male fiber attenuator is a male-female device, the same as fixed fiber attenuator, but also supports a variety of LC, SC, FC and ST and other joint methods. Female to male fiber attenuators are ground with PC, UPC or APC with an attenuation value of 1-30dB. It uses metal ion attenuation fiber technology to achieve attenuation effect, with light weight, high precision, various forms, easy to use, small size and light-resistant power light source and other advantages. Mainly used in optical wiring rack, fiber optic network system, high-speed fiber transmission system, CATV, OADM and DWDM systems.
