Fiber optic attenuators are mainly used in fiber optic to debug optical power performance & optical instrument calibration correction & fiber signal attenuation to ensure the optical power in a stable and desired level in the link without any changes on its original transmission wave.
There are several types of fiber optic attenuator for your choice,
fixed male-female fiber optic attenuators(1-25dB),
mechanical variable fiber optic attenuators(1-30dB),
variable fiber optic VOA inline attenuators SC/LC/FC/ST SM/MM (0-60dB).
Fiber optic attenuators are passive devices used to reduce the amplitude of a light signal without significantly changing the wave form itself. This is often a requirement in Dense Wave Division Multiplexing (DWDM) and Erbium Doped Fiber Amplifier (EDFA) applications where the receiver cannot accept the signal generated from a high-power light source.
FC/SC/LC/ST male to female fiber optic attenuator feature a proprietary type of metal-ion doped fiber which reduces the light signal as it passes through. This method of attenuation allows for higher performance than fiber splices or fiber offsets or fiber clearance, which function by misdirecting rather than absorbing the light signal. These attenuators are capable of performing in the 1310 nm and 1550 nm for Single-Mode and 850nm for multimode.
These attenuators are capable of withstanding over 1W of high-power light exposure for extended periods of time, making them well-suited to EDFA and other high-power applications.
Low Polarization Dependent Loss (PDL) and a stable and independent wavelength distribution make them ideal for DWDM.
