NEMI Focuses on Splicing

HERNDON, Va. -- The National Electronics Manufacturing Initiative (NEMI), an industry-led consortium focused on strengthening the North American supply chain, is launching a new project to improve optical fiber splicing. An informational meeting is scheduled for Wednesday, September 18, at the National Fiber Optic Engineers Conference (NFOEC) in Dallas. The goal of the new NEMI Fiber Optic Splice Improvement Project is to develop industry-wide splice quality criteria and test methods that will allow for systematic investigation of variability, comparison of equipment and procedures, improved yield and lower costs. "There are no widely agreed-upon acceptance criteria for fiber splices, and specifications often differ significantly between OEM, EMS, supplier and customer," said Peter Arrowsmith, advisory scientist for Celestica Inc. and chair of the NEMI Fiber Optic Splice Improvement Project. "One critical area is the splicer insertion loss estimate. Different splicer vendors use different techniques for estimating insertion loss, and the accuracy of these estimates is often insufficient to know whether the splice is acceptable, particularly when really low losses - less than 0.05 dB - are required. Industry would benefit from standardized criteria for estimating insertion loss, and this is one of the areas the project will address. We will also develop standardized procedures and requirements for strength criteria and test methods; splice protection, such as coating and sleeve; strip, clean and cleave effectiveness; fiber handling for prep and splicing; and fiber reliability assessment methods." The initial informational meeting will be held Wednesday, September 18, 2:00 to 4:00 p.m. in Room C150 of the Dallas Convention Center.. Presentations will also be made on other NEMI optoelectronics projects and will include information about the recently developed draft standard for fiber carriers for automated component assembly, and an update from the the Fiber Optic Signal Performance Project.
