Optical fiber technology is finding wide ranging applications in many areas including communications and sensors. In applications, such as "Fiber to the Home" (FTTH), large quantities of fiber optic components will be used and subjected to environments not usually encountered in "Central Office" applications. In Figure 1 a typical "POTS/Video" subscriber loop topology is shown. Telephone service (POTS) will operate in a bidirectional mode over a single fiber at one wavelength and video will be broadcast over a second wavelength to the subscriber. From the figure it can be seen that the link for a single subscriber requires two 3 dB couplers at wavelength 1 and two Wavelength division multiplexers operating at wavelengths 1 and 2. If interactive video, such as Video-Phone, is required an additional two 3 dB couplers, operating at wavelength 2, will be needed.
