Abstract: A method for terminating a multifiber connector. A multifiber ribbon is stripped to the appropriate preliminary length A protruding from the ferrule. A cleave is performed for all fibers protruding from the ferrule leaving a residual fiber length A1. Cleaving and fiber end-face forming can be achieved by either laser processing, electrical arch impact, plasma forming, or any other method of similar nature.
