Microwave ST Fiber Variable Optical Attenuators , Single Mode Fiber Attenuator
FOCC ST fixed fiber optic attenuator is used with ST connections. ST fiber optic 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. The ST fiber optic attenuators are metallic body and ceramic sleeves, it is female to male type attenuator used to connect the ST optical connectors while providing the optical power reducing at a certain level, the ST fiber optic attenuator are 1dB to 30dB range, capable of performing in the 1310, C and L Bands. We supply single mode ST / APC, ST / UPC fiber optic attenuators including the bulkhead ( Flange type ) ST attenuator and female to male ST fiber attenuator.
