Radiation effects on bend insensitive fibers at 1300 and 1550 nm

The induced loss in optical fibers during 'in situ' radiation, as well as fiber recovery after the irradiator has been shut down, is influenced by several factors. The present research has addressed radiation test results, both in situ and after radiation, on single mode fibers operating at 1300 and 1550 nanometers. This research investigates the damage mechanisms associated with optical preforms with and without phosphorus in the cladding and with enriched oxygen in the core. Fiber drawing conditions also varied. 8 refs
