Abstract :
Equipment called the Pulse Echo Fault Locator, incorporating a new method of direct presentation of results on a cathode-ray tube, is said to locate faults in undersea cables quickly, easily and accurately. The British firm which manufactures the locator reports that the equipment can pinpoint the area of a fault to within 80 yards in normal underwater conditions. It is being installed to maintain the Commonwealth round-the-world cable, and can also be used for land cables and for tests in cable manufacture.
