Moog Focal has launched its new 4 Gbps, pressure tolerant (PT) small form-factor pluggable (SFP) optical transceiver as part of its increased portfolio of qualified pressure tolerant technology, including pressure tolerant electronics and optical products for use in subsea applications.
Focal’s PT products feature a standard rating of 4,000 m (6,000 psi / 430 bar), and options for even higher pressures. To ensure reliability, all designs undergo rigorous qualification testing, and each product is test screened above the design rated pressure during factory acceptance, the manufacturer said.
With this newly qualified 4 Gbps offering, several existing 1 Gbps PT systems currently deployed in the field can now be upgraded to support higher bandwidth applications. Pressure tolerant products need to be enclosed in a subsea junction box typically filled with oil. Focal said it has tested compatibility with many typical oils used in the marine industry and continues to validate additional fluids as new applications emerge.
In addition to pressure tolerant slip rings and fiber joints for use subsea, Moog Focal supplies pressure tolerant solutions for composite video, HD video, Ethernet and serial channels, with thousands of products deployed subsea primarily in ROV systems.
Given the higher capacity of next generation multiplexer designs and the potential for integration cost savings associated with pressure tolerant technology, overall system costs for multiplexers could potentially be reduced by up to 50 percent while actually increasing data capacity.
The first order for the SFP optical transceiver will be supplied to MacArtney UK Ltd. for a project that requires high bandwidth data in tough pressure tolerant conditions.
