Open the CIPO recordAbstract From the Canadian patent
An array of optical fibers is precisely positioned in spaced apart channels in a head when a metal, such as tin-lead solder, is used to fix the fibers in the channel. A glass fiber is first ion plated with about one micrometer of a metal such as nickel which is wetted by the solder. The fiber is then placed loosely in a channel in a metal holder and solder is infiltrated to surround and adhere to the fiber. Strain on the glass fiber where it exits its holder channel is alleviated when the polymer jacket is also ion plated with metal and is bonded to the holder by solder.
