Maritime cables

For permanent installation on vessels and offshore facilities

Even in the event of a fire, optical fiber cables need to remain fully functional for a specified period of time (total system integrity). DNV GL type approval ensures that shipyards are able to install an optical fiber cable that has been tested and certified according to valid standards.

In shipbuilding, in particular, the reliable interplay of many components is of decisive importance to ensure trouble-free operation.

The first transatlantic telephone cable to use optical fiber

The first transatlantic telephone cable to use optical fiber was TAT-8, based on Desurvire optimised laser amplification technology. It went into operation in 1988. Third-generation fiber-optic systems operated at 1.55 μm and had losses of about 0.2 dB/km. This development was spurred by the discovery of Indium gallium arsenide and the development of the Indium Gallium Arsenide photodiode by Pearsall. Engineers overcame earlier difficulties with pulse-spreading at that wavelength using conventional InGaAsP semiconductor lasers. Scientists overcame this difficulty by using dispersion-shifted fibers designed to have minimal dispersion at 1.55 μm or by limiting the laser spectrum to a single longitudinal mode. These developments eventually allowed third-generation systems to operate commercially at 2.5 Gbit/s with repeater spacing in excess of 100 km (62 mi). fiber optic technician certification The fourth generation of fiber-optic communication systems used optical amplification to

What Are Backlinks?

Backlinks (also known as “inbound links”, “incoming links” or “one way links”) are links from one website to a page on another website. Google and other major search engines consider backlinks “votes” for a specific page. Pages with a high number of backlinks tend to have high organic search engine rankings. https://plus.google.com/url?q=https%3A%2F%2Fhoneywebsolutions.com%2F https://plus.google.com/url?q=https%3A%2F%2Fwww.honeywebsolutions.com%2F https://plus.google.com/url?q=http%3A%2F%2Fhoneywebsolutions.com%2F https://www.google.com/url?q=https%3A%2F%2Fhoneywebsolutions.com%2F https://www.google.com/url?sa=t&url=http%3A%2F%2Fhoneywebsolutions.com https://www.google.com/url?sa=t&url=https%3A%2F%2Fhoneywebsolutions.com%2F https://maps.google.com/url?q=https%3A%2F%2Fhoneywebsolutions.com%2F https://maps.google.com/url?sa=t&url=http%3A%2F%2Fhoneywebsolutions.com https://images.google.de/url?q=https%3A%2F%2Fhoneywebsolutions.com%2F https://maps.google.de/url?q=https%3A%

Radius of curvature

The radius of curvature of the cables must not be exceeded. The fiber optic cable may break when it twists or bends too much, especially during pulling. If there are no specific recommendations of the cable manufacturer, it should not be pulled at a radius of curvature less than 20 (twenty) times the diameter of the cable. When finished pulling, the cable should not have any radius of curvature less than 10 (ten) times the diameter of the cable. Vertical cable installations Whenever possible, it is better to lay the cables vertically down than to pull them up. Cables should be fastened at frequent intervals to avoid excessive tension in the jacket. They can be fastened with cable ties (well adjusted, but not enough to deform the cable jacket) or with Kellem type fasteners. Use the storage loops to help fix the cable and to provide cable for future repairs or re-installation.
