OZ Optics metalized fibers are specifically designed for optoelectronic packaging. The fiber is first coated with a layer of nickel to provide superior adhesion and a stable soldering base. The fiber is then plated with an overcoat layer of gold to provide resistance to oxidization. The result is a strong, uniform coating capable of handling the rigors of soldering and hermetic sealing. OZ Optics metalized fibers are well suited for use in assemblies that must conform to Telcordia requirements. If required, OZ Optics metalized fibers can be manufactured with masked ends. This process provides a clean, non-metalized fiber end suitable for termination with ceramic ferrules, fusion splicing or direct connection to a device. This allows for an easy transformation of devices into hermetically sealed packages. Also available are custom mid-span metalization of optical fibers and metalized ribbon fibers. The mid-span configuration provides a solution for hermetically sealing in-fiber devices such as Fiber Bragg Gratings, optical isolators or optical filters, as well as allowing larger package devices that exceed the length restrictions of standard metalized fibers. Metalization of ribbon fibers allows for easy hermetic sealing of multiple fibers into hermetic packages that require many fibers or are being used with V-Groove assemblies.
