Paper Abstract

The focus of this paper will be Oplink’s high-reliable fused coupler program. It is based on an Oplink proprietary fusion system design and offers a unique technology. The fusion temperature is extremely high so that the whole cladding glasses of the fibers are strongly fused together. The optical performance benefits provide superior stability over time and withstand extreme environmental condition changes. Additionally, the insertion losses and polarization dependent losses (PDL) can be achieved at extremely low values with almost no changes over time. The high reliability test shows results (beyond Telcordia requirements GR-1221-CORE) of up to 8000 hours in the damping heat test and the high temperature storage (at 100 °C). In addition, we will present the data results from other stringent tests. The FIT number is also estimated based on the test data. This unique fusion system design technology can be applied to a wide range of fused fiber products such as tap couplers and fused wavelength division multiplexers. In applications, it can be potentially implemented for fused products used in undersea submarine systems.
