It is a passive device used to reduce the optical signal strength without significantly changing the transmission wavelength. This device is used in dense wavelength division of high intensity optical powerIn transmission links such as multiplexer (DWDM) and erbium-doped fiber amplifier (EDFA), because the transceiver can not receive too high optical power, it needs to be attenuated.The metal ion erbium-doped fiber used by gongfeng company can effectively reduce the intensity of optical signal transmission,Compared with the fiber partial fusion method which only changes the optical transmission direction, the performance of ion erbium-doped fiber will be very different in all aspects.It is also suitable for use in 1310-1550nm, C and l bands.The optical fiber attenuator of gongfeng company can withstand high-intensity optical power transmission of more than 1W for a time, and better adapt to EDFA and other high-power applications.2. Low polarization loss (PDL) and stable independent wavelength distribution make optical fiber attenuator an ideal choice for DWDM.3. According to the absorption effect of metal ions on light, an attenuation optical fiber doped with metal ions is developed. Like ordinary optical fibers, this attenuation optical fiber also has attenuation coefficient per kilometerA fixed attenuation coefficient, except that this attenuation coefficient is not calculated in kilometers, but in millimeters. The attenuation optical fiber is threaded into the ceramic plug core and treated by special process,It can be made into a yin-yang fixed attenuator.It is suitable for 1260 ~ 1640nm bandwidth, 1310 ~ 1550nm dual wavelength and C and l bands.The attenuation range is 0 ~ 30dB, with a wide range of applications, such as optical fiber transmission system, erbium-doped fiber amplifier, dense wavelength division multiplexer, optical add drop multiplexer, cable TV system, etc
