Publication number: 20060177191Abstract: A Terminator by Tapering Fiber Optic (herein after named TermTaper) made directly using a single mode optical fiber to reduce the back reflection in an installed optical fiber link, which occurs when a guided incident optical signal encounters an index of refraction change at a glass-air transition. The single mode fiber has at one end, a first length of exposed fiber which is obtained by way of stripping the jacket from that portion of fiber. The bare fiber is positioned in a suitable heating set in order to enable a biconical taper to be formed on that portion of bare fiber. The biconical taper contributes to obtain a return loss of better than 55 dB for any guided optical signal that propagates through the TermTaper. The TermTaper is assembled in any type of suitable mounting device.Type: ApplicationFiled: February 28, 2006Publication date: August 10, 2006Inventor: ROLAND COTE
