Birns Develops New ABS Certified Optical Penetrators

Nicole Ventimiglia

BIRNS, Inc. recently developed a set of ABS certified fiber optic penetrators for a manned submersible.  BIRNS, an ISO 9001:2008 certified developer of high performance connectors, custom cable assemblies, penetrators and lighting systems for the subsea market, engineered the exclusive penetrator design that included six single mode optical fibers. The robust penetrators were custom overmolded in BIRNS’ NAVSEA PRO-020 certified molding facility, and feature low insertion loss of < .2dB and high return loss of >35dB. ABS worked with BIRNS to develop rules for witnessing the testing of the new design.
