SKU: OPSP

The optical power surge protector is a two-fiber port module that has a low insertion loss during normal operation but suppresses an optical power surge quickly (about 100ns) and maintains a preset maximum allowed output power as long as the surge presents. This is achieved by using a detector to tap a small amount of light from the output and feed into a closed-loop circuit to control an NS variable fiber optical attenuator connected between light input and output. The maximum output power is manually set by a resistor pot through a screw hole with a range from 200mW to 2W.  High maximum output power up to 10W is available through special order.  The optical power surge provides an ultimate solution for sensor protection.  The non-mechanical device has passed the most stringent mil-spec and space flight qualifications and is designed for over 20 years of continuous operation.  The module comes with a wall-plug 12V power supply.
