Novel V-groove-based interconnect technology

Abstract

A novel fiber optic interconnect technology based on injection molded V-grooves that uses the fiber’s inherent precision to provide a reliable, robust and consistent optical connection is described. This technology has been expanded and applied to optical transceivers that can now achieve the same port density as that of current copper-based systems. Both the interconnect and the optical transceivers are shown to have performance levels similar to current ferrule-based multimode technology. Testing was performed in an effort to accurately measure performance and qualify the connector design for field use. Test results for the interconnect met the performance requirements of Electronics Industry Association/Telecommunications Industry Association (EIA/TIA) 568, which represent test standards for local area networks. Results of insertion loss and return loss performance of the duplex ferrule-less connector design were measured when 400 unique links were tested using 62.5 mm multimode fiber. Mating durability performance tests were performed in which plugs were reconnected to the socket 500 times. A new generation of small form factor transceivers is discussed that were developed using the same V-groove technology. Optomechanical tests are reported that show the performance level of these new transceivers is comparable to existing ST transceiver technology.
