The 980nm 1030nm 1064nm high power fiber optical isolators is a fiber-coupled component that allows all polarized light signal (not just the light polarized in a specific direction) to propagate along a fiber in one direction but not in the opposite direction. Functionally, it is quite like an optic-electrical diode. The 980nm 1030nm 1064nm high power fiber optical isolators are necessary in fiber optic systems in many roles the most common of which is the prevention of back-reflected light coming back down a fiber from re-entering and disrupting the operations of a laser. Boxoptronics provide 1W,2W,3W,...,10W or other high power Polarization maintaining fiber isolators.
The Manual Variable Fiber Optical Attenuator allow the user to manually vary the attenuation of the signal in the fiber as it is transmitted through the device. These VOAs can be used to to precisely balance the signal strengths in fiber circuits or to balance an optical signal when evaluating the dynamic range of the measurement system. The Manual Variable Optical Attenuator have single mode or PM fiber pigtails with a 900um jacket. The VOAs are offered unterminated or terminated with FC/PC or FC/APC connectors.
