Fibre Optic splicing

The optical fiber splicing technique used to permanently join two optical fibers in a low loss connection. We made this connection  using one of two methods – fusion junction or junction mechanics.

Fusion splicing connection offers the lowest losses. This technique uses a device called a splicing machine fiber optic fusion junction to make fibers. Splicing machine fiber optic fusion accurately aligns the two fibers and then generates a small arc to bond the two fibers together. A good fusion splicing machine will deliver consistently low loss junctions, typically less than 0.1 dB for single-mode or multimode fibers. However, such splicing machines are quite expensive and bulky and can be difficult to use. To obtain a competence in an operation we offered to our employees a proper training.

A note of caution: electric spark generated by a fusion splicing machine can cause an explosion when flammable gasses are present. You have to use the fusion splicing machines in safe rooms without flammable gasses.

Stripping process

We are stripping the cable handling tools, designed to not damage the individual fibers. Dissolution of a fiber provides a uniform surface, perpendicular, which will allow maximum light transmission to other fiber. Shrinking sea at a junction is usually due to either a bad junction or a faulty fiber dissolution. You have to use a good quality sales tool. We place immediately a fusion splicing, a protective element, for covering the junction fiber. Protection element junction to junction endurance add fiber and protects it from contaminants.

We kept the splicing fiber in a junction box after the completed weld. We secure the protection element for optical fiber fusion splicing or mechanical junctions in a holder junction box that sits in the center of the junction. The team  glued the junction to the box with a layer of contact cement if the support junction is not there, or if it is not the size or type correctly

Do not use tape to attach the junction box junctions. Then, you have to mount the splicing box in the housing junction. This protects splicing and exposed fibers and provides a means of accessing a junction, if necessary. You should install the connectors directly on the optical fiber cable without the need for junction boxes and carcasses or use junction.

We are making the outdoor splicing usually in a van or tent junction to protect exposed fiber and equipment environment. As a result, it also protects tools, equipment, and fibers from blowing down by the wind.

Installation cable

Installation cable, it is important to let a piece long enough cable entry and inside the casing junction to junction van or tent. You have to make all the junctions on a large table, clean, with enough space for all the equipment and cables junction. A team of splicing optical fiber consists usually of two technicians: a junction and an OTDR, optical power meter or operator.

We use the most relevant principles to achieve many fibre optic cable systems:

  1. Identify the exact route of the cable and make sure it meets all specifications for fiber optic cable installation. We have all the authorizations and permits required to install cable along the route.
  2. Complete the design of the cable and include the following:
  • We identify equipment beam of light and ensure that the equipment will function properly in cable design.
  • Determine the type of fiber and calculate or measure (for existing cable) total optical loss, dispersion and other limitations on bandwidth.
  • Installation of the exterior, interior installation, wide tube, tight buffer, reinforced, fireproof, the number of fibers, etc.
  • Location of junction lengths of cable drum, crews junction, locations allocators fiber.
  • Determine what type of connector and connector installation procedure (fibre optic connectors, breakout cable, fib direct connection).
  • See chapter 5 for more details

Installation of fiber optic cable

  1. Identify all risks of installation and safety issues.
  2. Make sure you are available and appropriate testing equipment installation. Determine the correct installation procedure and schedule.
  3. Order cables and all necessary equipment, as designed, to allow for proper delivery.
  4. Once we installed the cable, we perform testing before installing cable rope drum.
  5. Prepare route cable and install all pipelines, canals, channels interior load-bearing cables, and so on, as needed.
  6. Installation of fibre optic cable project as provided in the engineering project.
  7. Junctional separate lengths of cable together, as needed.
  8. Finish the cable housings or junction splitters and finalized proper cable installation.
  9. Testing OTDR and power meter installation completes. Ensure that test results installations fall into design criteria.
  10. You must always install all equipment sheaves of light modems and multiplexers, and so far final.
  11. Connect the equipment at the facility sheaves of light control and fibre optic test (BERT or equivalent).
  12. Sign all the necessary infrastructure, including drawings route properly assigning fiber loss amounts, OTDR traces.
  13. Prepare emergency repair plans.

We use two types of different cable, indoor and outdoor. Outdoor cable is very tough to withstand extreme conditions, while the interior is a more flexible cable. Each type of any cable that we installed in any indoor or outdoor installation uses different techniques.

The exterior installations are 2 types of air and underground installation.

We buried the cable directly in the ground or installed in a microtube buried. We use direct burial cable over long distances. Once we installed the equipment according to digging, the installation process will unfold very quickly.

As an alternative, installing cables microtubules may provide additional protection for the environment, thus allowing future installation of other cables or removing them without having to dig. We use this method in urban installation.

Installing underground fibre optic cable

You should study soil conditions before starting of excavation. You must determine several things: selecting equipment installation, type of cable and microtube (if used) and installation depth. The team identified all existing underground utilities such as buried cables, pipes and other structures along the route of cable installation and positioned. Access roads are established before proper excavation.

For underground installation we use drilling. We use this technique in the places with a hard surface, such as major thoroughfares, highways or rails. Drilling machine can perform 1-3 cm diameter holes at distances up to 500m. During the drilling process, we pulled the micro tube. We pull the cable through microtube, once we have completed the drilling.

Fibre optic cable

We place the cable in a hole 30-40 inches, depending on soil conditions, wear and surface freezing conditions. For instance, we made an installation at a depth of 40 inches or more on agricultural land or a crossroad. In the cold lands, we buried the cable below the frost line to avoid damaging it.

We keep the grooves as straight. The team should flat the surface trench for fibre optic installation underground and level with small stones. They use a lightweight filler to provide a charging cable distribution better, reducing risks and lowering risks damage to the cable bending losses.

Labels warning light should directly above buried cable to warn future excavation operations. To find the location of buried cables, the workers use boxes or special detection markers.  The cable buried in a galvanized steel pipe diameter 2-3 inches in locations such as intersections underground roads or railroad tracks junction.

We use the pipe as protection and keeps the load cable during digging operations. Also, to protect the cable, we use small flagstones recessed top of the cable.

For providing tensile strength or protection against rodents we use a cable with a coating of steel. We must ground the cable very well in all terminations, junctions, and entrances of buildings whenever we use a conductive coating as steel. Welds fiber optic cable must be enclosed in a sealed box specially made for installing underground fibre optic cable directly.

We use blasting technique to install the cable in a tube or microtube. A fibre optic cable installation specialized equipment is at one end of the tube, or microtube. The tube is feeding the cable blowing equipment and pulled in about 200 feet. Airflow from the tube at this pressure pushes the cable into the tube.

The team installs the cable fairly quickly using this technique without damaging the cable. The speed of installation of the cable is 200 feet. The tube walls must be installed in HDPE, suitable for the proper filling ratio (50 to 80%). The high filling ratio may prevent movement of the cable through the tube kinks and you use a continuous length of the tube. The high-pressure air mustn’t affect the tubes. The specialized teams used for this process must follow the instructions of blowing equipment.

Installation lengths can vary, considering the number of twists in the tube, filling ratio and type of equipment.
