An annealing mold and fiber retaining device includes a fiber holding plate having fiber channels and an annealing insert. Retainers are provided for attachment to the plate to retain fibers in the channels. After annealing, the annealing insert is replaced by a packaging insert. The fiber holding plate is mounted between a support plate and a cover plate. The mounted plates include a coextensive current conductor port and the plates are mounted in a housing which includes vibration mounts for isolating the plates from vibration within the housing.
