Abstract:
An optical power monitor for connection between an input optical fiber and an output optical fiber for sampling a portion of the optical power transmitted therebetween and determining the optical power magnitude; the monitor comprising:an optical fiber and ferrule assembly connected to said input and output optical fibers, respectively; a first glass tube enclosure radially enclosing said assembly; a collimating lens substantially adjacent said assembly for collimating light from said input optical fiber; an optical filter configured as a partial mirror coating on an end of said collimating lens for passing said portion of said optical power and for reflecting the remainder of said optical power back through said collimating lens and into said output optical fiber; a second glass tube enclosure radially enclosing said collimating lens including said optical filter and axially bonded to said first glass tube enclosure; and a photon detector substantially adjacent said filter and bonded to said second glass tube enclosure.
