1PCS New Fixed Fiber Attenuator Connector Adapter 0~30dB FC/ APC Female To FC/APC Male Coupler Optic Equipment Factory Wholesale
Note to customers:
This optical fiber attenuator has attenuation values of 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 ~ 20dB (please note when placing order!)
Attenuation value: 0.5dB
Optical fiber interface: FC
FC / APC male to FC / UPC male fiber attenuator
It can withstand high-power optical signal transmission for a long time and better adapt to EDFA and other high-power applications.
Male and female fiber attenuators
1. It is a kind of passive device used to reduce the intensity of optical signal without changing the transmission wavelength significantly. This device is used in dense wavelength division of high intensity light power
In the transmission links of DWDM and EDFA, the receiver and transmitter can not receive too much optical power, so they need 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 biased fusion method which only depends on changing the direction of light transmission, the performance of ion doped erbium-doped fiber will be greatly different in all aspects.
It is suitable for 1310-1550nm, C and L band.
Gongfeng's fiber attenuator can withstand high-intensity optical power transmission of more than 1W for a long time, which is better adapted to EDFA and other high-power applications.
2. Low polarization loss (PDL) and stable independent wavelength distribution make fiber attenuator an ideal choice for DWDM.
3. According to the absorption of metal ions to light, the attenuation fiber doped with metal ions is developed, which has the same attenuation coefficient per kilometer as ordinary fiber
Fixed attenuation coefficient, but this attenuation coefficient is not calculated in kilometers, but in millimeters. The attenuating optical fiber is inserted into the ceramic insert and treated by special process,
It can be made into a fixed attenuator of Yin Yang type.
It is suitable for 1260 ~ 1640nm bandwidth, 1310 & 1550nm dual wavelength, C and L band.
Attenuation range 0 ~ 30dB, wide range of applications, optical fiber transmission system, erbium-doped fiber amplifier, DWDM, OADM, CATV system, etc.
