Underwater Fibre Optic Cable FAQs – The Ultimate Buying Guide
What is Underwater Fibre Optic Cable?
Underwater fibre optic cable is one kind of communication fibre optic cable that is laid under water through rivers, lakes and beaches and other places. This cable laying environment conditions are much worse than the pipeline laying and direct burial laying .
How Does Underwater Fibre Optic Cable Work?
Underwater fibre optic cable has layers of steel wire or steel tape armoured structure. The structure of the inner sheath and outer sheath are also needed to take into consideration according to the hydrogeological situation of the river.
For example, in the stony soil, scouring seasonal riverbed, fibre optic cable suffers from wear and tear and high tension, not only thick steel wire is needed for armouring, but even double layer of armouring is required. The method of construction should also be selected according to the river width, water depth, flow rate, river bed, flow speed, river bed soil and so on.
How Can Underwater Fibre Optic Cable Has Great Performance?
The performance of underwater fibre cable comes from its cable design, materials quality, production quality, and the laying techniques.
A perfect fibre cable design for a underwater fibre cable should consider all the conditions in its actual site, such as river bed soil quality, river width, water depth, flow rate, and other site conditions.
The raw materials and production all affect the final quality and performance of a underwater fibre optic cable. So a trustworthy brand or manufacturer is very important.
They will solve you all the problem of materials comparison with reliable quality inspection and experienced and advanced production technology.
First of all, the laying speed and specified position of the optical cable shall be controlled.
During the laying process, the optical cable shall not be vacated in the riverbed, and shall not make a small circle. It is also necessary to monitor whether the underwater fibre cable is in good condition, and solve the problem in time to ensure the laying quality of the underwater optical cable.
The laying length should be based on the length of the optical cable determined during the re-measurement route. Generally, the underwater optical cable should extend out of the embankment or the shore for 50 meters. When the design stipulates that the optical cable is laid in an arc at the bottom of the river, it should be based on the baseline at the time of measurement, and the arc should be laid upstream.
What are the Applications of Underwater Fibre Optic Cable?
Underwater fibre optic cable takes following measures to ensure the waterproof performance of the fibre optic cable to laid in lakes, rivers and beaches.
- Single wire centre reinforcement
- Loose tube filled with special waterproofing compound
- Complete core filling
- Plastic coated aluminum tape (APL) moisture barrier
- Double-sided plastic-coated steel tape (PSP) improves the moisture resistance of the optical cable
- Good water blocking material to prevent longitudinal water seepage of the optical cable
When laying fibre optic cables in mountainous or hilly areas, these areas generally have steep terrain, many trees, more rocks and less soil. It is unavoidable to use a protective and good mechanical fibre optic cables.
Because underwater fibre cable has excellent tensile and flattening properties, and has a certain ability to withstand rock crushing and excessive tensile force, it is also suitable for these aeras as climbing fibre cables.
Although underwater fibre cables are laid in the lakes or rivers, it is also cab be considered as a directly buried fibre optic cable. Moreover, it has more strict requirements than normal directly buried fibre cable on the ground. So a underwater fibre optic cable is also suitable for direct burial applications.
What are the Benefits of Underwater Fibre Optic Cable?
Most fibre optic cables are installed by aerial, duct and direct buried. But when it comes to places with rivers, lakes and beaches, traditional fibre cable laying method would require lot of fibre optic cables and installation costs.
And underwater fibre optic cable perfectlly solve this problem by connecting the both ends with underwater laying. It saves lots of fibre cables, and the laying is also simplified.
Other than that, with the fibre optic cable under the rivers and lakes, it won’t be affected by wind and most animals above ground. Actually, it provide more reliable optical communication networks.
What is the Difference Between Underwater Fibre Optic Cable and Submarine Fibre Optic Cable?
As its name suggests, submarine fibre optic cable (or subsea/undersea fibre optic cable) is fibre optic cable that is laid in the ocean.
To meet the application requirements, the structure of submarine fibre optic cable requires strong and light materials, but not light metal aluminum, because aluminum and seawater will produce hydrogen by electrochemical reaction, and hydrogen molecules will diffuse into the glass material of the fibre, making the loss of the fibre larger.
Therefore, the submarine fibre optic cable must prevent both the internal generation of hydrogen and the infiltration of hydrogen into the fibre optic cable from the outside.
Most of the submarine fibre optic cables are under the sea at a certain depth and are not subject to damage from natural environment such as wind and waves and interference from human production activities. So the submarine fibre cables are safe and stable, with strong anti-interference ability and good confidentiality performance.
What is the Difference Between Underwater Fibre Optic Cable and Direct Buried Fibre Optic Cable?
Direct buried fibre optic cable refer to a fibre optic cable which has good performance of resisting external mechanical damage and preventing soil erosion.
Fibre optic units is normally armoured with steel tape and other materials such as double sheath and steel wire outside, and make it is available for directly buried in the ground. Direct burial is the most convenient laying method for fibre optic cable and also save the duct and aerial installation costs.
And the major difference is that the laying environment of underwater fibre optic cable is much worse than the conditions of direct burial laying. So the underwater fibre cable must use steel wire or steel tape heavy armoured structure. Which make most underwater fibre optic cable are available for direct buried laying.
In addition, the repair underwater fibre optic cable failure techniques and measures are also much more difficult, so the reliability requirements for underwater fibre optic cable is also higher than direct burial fibre optic cable.
What are the Types of Fibre Optic Cable?
According different aspect of fibre optic cable, there are many types of fibre optic cables.
Due to different transmission mode of an optical fibre, there are single mode fibre optic cable and multimode fibre optic cable.
How the fibre optic cable is structured is also an important specification of a fibre cable. There are tight buffer fibre cable, loose tube fibre cable, uni-tube fibre cable (or central loose tube), MLT (multi loose tube) fibre cable.
Different application of a fibre optic cable has different requirements on the cable installation and laying. For instance, there are overhead/aerial fibre optic cable, duct fibre optic cable, direct burial fibre optic cable and underwater fibre optic cable.
Where a fibre optic cable is used affect its specifications too. At a larger scale, we can divide them into the outdoor fibre optic cable type and indoor fibre optic cable type.
For different application and specs to meet, the fibre optic cable armouring also varies. From light armoured aluminum tape fibre optic cable, corrugated steel tape armoured fibre optic cable, steel wire armoured fibre optic cable, and heavy armoured fibre optic cable with both steel tape and steel wires.
Besides all mentioned above, some industries and network system has specific type of fibre optic cable, such as mining fibre optic cable, FTTH fibre cable, power line fibre optic cable and so on.
What are the Materials for Underwater Fibre Optic Cable?
Like all the fibre optic cables, underwater fibre optic cable are made of optical fibres in loose tubes. All loose tubes are stranded along an dielectric FRP central strength member in the inner sheath with water-blocking materials.
Sometimes, there is also a layer of corruggated steel tape wrapping the fibre core, to provide extra mechanical performance for the underwater fibre cable.
Outside the inner fibre core, there are a layer of steel wire armuor (SWA) and another layer of water-blocking tape to make the underwater fibre optic cable more compact and protected from its application environment. Finally, there is an outer sheath made of PE sheath.
