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.
