BIRNS Develops ABS-Certified Optical Penetrators for Manned Submersibles
BIRNS was recently called upon to develop a unique set of ABS-certified fiber optic penetrators for a manned submersible. It engineered an 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 35dB.
The certification for optical penetrators was new territory for ABS, so the organization worked with BIRNS to develop rules for witnessing the testing of the new design. While the two optical penetrators called for a 1,000-meter depth rating, BIRNS can design the line with ratings to 6,000 meters, along with options for a range of fiber counts.
