AT&T Awarded $157 Million Contract

To Build Undersea Fiber-Optic Cable —Color Brochure Available

AT&T has been awarded a $157 million contract to build a new un- dersea fiber-optic cable that will link the U.S. mainland to Hawaii in 1993.

Known as Haw-5, the cable is the fifth to link Hawaii to the mainland and the second fiber-optic cable to do so.

The cable, which will carry voice and data traffic, includes three pairs of fiber, two active and operating at 560 megabits per second and one fiber pair for reserve. If the entire cable were used for voice, it could handle 80,000 simultaneous tele- phone conversations.

The world's first transoceanic lightwave system, TAT-8, went into service in 1988 and has a capacity of 40,000 simultaneous telephone calls.

TAT-9, to be deployed in 1991, will handle 80,000 simultaneous calls.

A new fiber-optic cable would have a capacity of 600,000 simulta- neous conversations using optical amplifiers and operating at 2.4 giga- bits (billion bits per second) over two pairs of fibers and using con- ventional compression techniques.

AT&T Bell Laboratories scien- tists are experimenting with optical amplifiers in ultra-long-distance systems and in systems for island- to-island or coast-to-coast transmis- sion. Related research involves high-repetition lasers, pump lasers, all-optical logic elements, integrated optical waveguide devices, and new types of optical fiber.

AT&T also announced that it is adding a $6 million robotic Seabed

Tractor to its stable of undersea cable laying equipment. The 10-ton vehicle can begin burying cable at the top of a beach, drive through the surf and continue laying cable until the water is almost a mile deep.

Undersea cable is buried in a trench about 3 feet deep. When trenching, the hydraulic-powered

Seabed Tractor travels at speeds ranging from 3 to 15 feet per min- ute, and can reach speeds up to 150 feet per minute when not trench- ing.

The Seabed Tractor, which is

NEI Syncrolift Wins Over $3 Million In Orders For

Shiplifts, Transfer Systems

NEI Syncrolift of Miami, Fla., a world leader in shiplift technology, has received two more orders for shiplifts and transfer systems val- ued in excess of $3 million.

One order for an eight-hoist unit with a lifting capacity of 1,150 tons was placed by the TOA Corporation of Japan. The Syncrolift, for instal- lation at Port D'Agadir in the King- dom of Morocco, is to be used for the docking of fishing vessels.

The second order, for an 1,860- manufactured by Soil Machine Dy- namics in Newcastle, U.K., will be stationed in Baltimore.

Circle 39 on Reader Service Card ton unit, was placed by Etermar of

Lisbon, Portugal, for a Syncrolift

Shiplift and Transfer System for installation on the Island of Madei- ra, off the coast of Portugal.

These new orders bring to 190 the number of Syncrolifts installed or under construction in 63 countries around the world. Currently, there are nine new Syncrolifts under con- struction in Europe, Japan, the

Middle East, Africa and in the Pa- cific. The largest of these is capable of handling vessels of up to 100,000 dwt, while the smallest lifts less than 300 tons.

Maritime Reporter/Engineering News "Engineered for extremes.

That's the meaning of'Skookum'."

Skookum originated in logging. There's no tougher test than work in the woods.

And in logging lingo, "skookum" means the best.

When we started serving the fishing industry, we introduced trawl blocks, shackles, and hooks that are engineered tor extremes.

Our best testimonials come from fisher- men. When conditions are as bad as they can get, Skookum equipment keeps working. And Skookum lasts longer, making it an even better investment.

We're proud to wave the flag, too. All

Skookum equipment and parts are made in the U.S.A. This means the finest quality, faster delivery and better availability.

Hey, when you're 500 miles out at sea and fishing is at its peak and there is a storm whipping up, rigging should never be a worry. Right? Reliability is crucial.

That is why Skookum is catching on fast in the fishing industry.
