BIRNS, Inc., an ISO 9001:2008 certified global leader in the design and manufacturing of unique lines of high performance connectors, custom cable assemblies, penetrators and lights, has launched a new line of innovative fiber optic penetrators. The versatile design is tailored for the rigors of the subsea environment and can be adapted to a wide range of different cables.
The new BIRNS fiber optic penetrator line comes standard with pressure rating of 70 bar (1,000 PSI/2,300 FSW), but can be specified to higher rating, depending on the application, from ROV and AUV use, to defense submersibles and sonar arrays. These rugged penetrators are meticulously engineered to enable reliable fiber transmission through a bulkhead and are extremely durable—constructed of AISI 316 stainless steel that’s passivated per ASTM A967-05. They are rated for use up to 80°C (176°F) when fabricated with neoprene (polychloroprene) cable jackets, or up to 95°C (203°F) with optional CSPE cable jackets.
The line has extremely low insertion loss (<0.1 dB per channel), and conversely high return loss (>65 dB per channel.) Like all BIRNS penetrators, they meet or exceed ABS and DNV requirements when fabricated with Low Smoke Zero Halogen (LSZH) cables inboard, and are each individually serialized, certified and tested in accordance with BIRNS’ ABS-approved test procedure ETP-6510-101.
