Self-coupling

Communications installers are often faced with the urgency of doing some kind of work in the field, at the same time finding themselves unarmed for the task at hand due to the lack of necessary materials on hand. A true professional should be ready for anything, you say. But often the problem of lack of tools or material comes from management, who prefer banal savings to quality of work, without considering the risks. The installer, in any case, has to solve the problem on the spot, because the payment for his labor depends on it.

How, for example, to make a less tolerable cable sleeve out of what is on hand?

Ukrainian telecom operators, who have become hostages of a lengthy military conflict for lack of funds and materials, began to make couplings out of plastic pipes. As a result - good clutches with moisture protection.



Some operators in Russia, even in peacetime, do not hesitate to use such crafts when building their networks. According to eyewitnesses, such optical couplings from plastic pipes can be seen in Serpukhov. In plastic pipes they even manage to push the switch .

The user of our forum even shared a simple recipe for creating such a clutch.

The sewer coupling from plastic undertakes:


As the fastener on the support, ordinary clamps will fit:


Cable entries:


The cassette can be purchased at a specialized store:


By the way, it turns out that it is about two times cheaper than a conventional optical coupling.

Quickly put the cable into the clutch can be even easier and cheaper. A standard cable gland for CCI 100x2 cable, 50x2 possible.


According to the user of our forum, Alex 8031, in order to quickly equip the cable into the clutch, you can use almost any available tools than to spend conditional fifteen hundred rubles with each break of the cable.

A standard coupling for cable chambers of the Chamber of Commerce and Industry 100x2 is taken, it is possible 50x2 (such ones are not in demand now and cost from 30 to 50 rubles).

As a cassette fit "piece of wood" from a nearby fence. The ends of the cable with sanitary clamps are mounted on the edges of the plank. The sleeves are fastened with small nails around the perimeter of the “piece of wood”. After welding the fibers, the sleeve is sealed by heat shrinkage or welding.

Such crafts can hang in the span of the cable for years. It will be sealed and will not attract too much attention.

In the distant and crisis-year 2007, the management of one of the operators offered its employees to resort to self-made production of optical couplings. In order to save, naturally. Here is how it looked.

Installers took a plastic pipe with a diameter of 25-30 mm and divided into segments of 20 centimeters. Along the edges made holes for fasteners. On the one hand for fixing the cable, and on the other for optical patch cords.


Next, the fiber was trimmed so that the module tube protruded several centimeters from the common cable sheath. After welding and shrinking of the sleeves, the sleeves are attached to the module tube, the fiber is laid in a figure eight and secured with a mounting tape.



Then the clutch, patch cords and cable secured with ties. From the ends, the tube was sealed with raw rubber, and the whole structure was wrapped with insulating tape.



Fastened the clutch on the back of the box.


At the beginning of the zero, pioneers in the provider often faced financial problems, solving them with their wit and skillful hands. Here is the story of one small operator, who, when laying the cable, faced its shortage. It was considered economically inexpedient to buy a cable of greater metricity and lay it anew, so they decided to simply increase it. At the place of the cable splicing, they installed an airtight coupling made of scrap materials. For this, we bought a sealed box and cable entries.


Volkona spliced ​​mechanical slices, and after fixing the walls of the box with velcro.




Here is another similar example.

Horror

Some Krasnoyarsk operators use ordinary cable channels as a clutch. Such miracles can be seen on supports. Most often, the clutch is made from an ordinary plastic bottle.





There is such.



In absolutely hopeless cases, the cable may be put in a cardboard box.





Such ingenuity and frank carelessness can be met in the open spaces of our country, where a vast network of optical fibers stretch, allowing us to download our favorite films, “like” photos of friends on social networks and chat.
