The fiber attenuator is a very important fiber optic passive device that appears with the development of the optical communication industry.The optical fiber attenuator is an optical device that can reduce the energy of the optical signal.It is used to attenuate the input optical power, avoiding the distortion of the optical receiver due to the super strong input power.Optical fiber attenuators are mainly used in: fiber optic communication network, fiber optic data network, fiber optic CATV network. Optical fiber attenuator test system features: high attenuation accuracy, low additional loss, and good stability.
The intensity of optical signals received by various optical receiving devices is limited and needs to be within a certain range.If the optical power is too weak or too strong, the device cannot work normally.When the optical power is too strong, the optical attenuation will be used to adjust the optical power to reduce it to the allowable range.Otherwise, even if the device can be used, it will be detrimental to its life.Therefore, the role of optical fiber attenuators is still very large.
Optical fiber attenuator is an optical device that can reduce the energy of optical signals.It is used to attenuate the input optical power, avoiding the distortion of the optical receiver due to the super strong input optical power.Optical fiber attenuator, as a kind of optical passive device, is used for debugging optical power performance in optical communication system, debugging calibration and correction of optical fiber instrument, optical fiber signal attenuation products are made of attenuating optical fiber doped with metal ions, which can Adjust the optical power to the desired level.
Optical fiber attenuators are used to attenuate performance loss caused by long-term use of optical fibers.Usually, optical fiber attenuators need to be tested on the real machine.While fiber attenuators can simulate the long-term loss of light in a fiber, they cannot simulate the dispersion due to the length of the fiber.Simply put, in an optical module, the bit error rate (BER) can be reduced by using a optical fiber attenuator.In order to achieve the best bit error rate, it is necessary to reduce the optical power, which requires the use of fiber attenuators.When the transmitter is too close to the optical module, excessive power will be generated.
The shape of the fixed optical attenuator is more like an adapter.The fixed optical attenuator is mainly used in optical communication systems, adjusting optical power performance, calibrating and correcting optical fiber instruments, and attenuating optical fiber signals.The product is made of attenuating optical fibers doped with metal ions to adjust the optical power to the desired level.Jumpers of FC, SC, ST and LC connectors can be used.The fixed optical attenuator is very convenient to install and easy to use, and is loved by many users.
