Starting in his garage in 1983, Scripps Institution of Oceanography Ph.D. student Mark Olsson created DSP&L’s first product, the SeaBattery™ power module. Capable of supplying stable and reliable power at full ocean depth, this product remains widely utilized worldwide over 30 years later. DSP&L’s collaborative and creative approach to product design put them in the position to engineer custom lighting for the Titanic expeditions. Product designs that push the technological boundaries of their time continue to be among DeepSea Power & Light’s core strengths.
DSP&L emphasizes a beyond-minimum approach, commonly designing products to withstand depths beyond existing industry limitations. The team is guided by several basic principles when creating any new product design: performance, immersion longevity, durability, and compact form factor are just a few of the underlying concepts considered a necessity for any product that bears the DSP&L name. Examples of this include sapphire crystal ports used in place of glass or acrylic; titanium housing options, and industry-leading miniaturization of lights and cameras. The DSP&L design approach ensures that products will perform where and when needed while minimizing costly down-time. This has resulted in the design of the industry leading LED SeaLite Sphere family of lights. Flicker free and fully dimmable, these units are capable of outperforming a 400 watt Metal Halide (HMI) at a fraction of the price and size.
Among its contributions to subsea imaging technology, DSP&L strives to enable new applications for HD video. This includes the HD Multi SeaCam® family of cameras: the industry’s first full-HD tooling camera with integrated coax and fiber optic outputs. The compact size of the HD Multi SeaCam tooling camera enables integration of HD video on smaller platforms and in a wider variety of placements than previously possible; including manipulator arms, pan and tilt units, and smaller ROVs. As well as for tooling purposes, the wide angle view on these cameras creates a new class of HD context cameras providing pilots with full operational awareness. In 2015 DSP&L is continuing this innovative drive with the announcement of the industry’s most compact full HD optical zoom camera and their innovative FleXlink™ HD-SDI transmission technology.
Existing coax and fiber optic interconnects are bulky, expensive, and delicate compared to the compact and robust HD Multi SeaCam tooling camera. In order to decrease the footprint, improve reliability, and reduce operation costs for HD video systems, DSP&L engineered their FleXlink technology: a HD-SDI transmission solution utilizing existing Ethernet interconnects.
By taking advantage of the controlled impedance of twisted pair Ethernet cable, FleXlink sends full bit-rate, uncompressed HD-SDI formatted video over distances of 10 meters through existing subsea connectors and cables. A FleXlink media converter, placed in an existing multiplexer (MUX) or dedicated housing, converts the signal to either a coax or fiber optic HD-SDI output by means of a Small Form-factor Pluggable (SFP) module. With a compact size of just 63mm x 40mm (about the size of a typical business card), the FleXlink media converter can fit into even the most crowded multiplexer configurations. As the FleXlink board outputs either coax or optical HD-SDI data, no additional hardware is necessary to connect with commonly utilized multiplexing hardware.
DeepSea Power & Light is committed to pioneering technologies that increase product utility, performance, durability, and value. Solutions driven by technological capabilities are developed alongside demands from industry leaders. The FleXlink solution is the latest example of a DSP&L offering to provide greater earning potential to system operators while reducing long-term costs. This trend continues with the upcoming release in 2015 of its 4x Optical Zoom HD Camera, available with the FleXlink solution.
DeepSea Power & Light’s philosophy of innovation and quality will bring new products with unique capabilities to the subsea marketplace for years to come.
