Telecom’s Growth Drives

The support person should also be involved to the point that he can answer most questions. You may even have more technical knowledge about the project, but you cannot have full authority to make decisions. In large projects, this person may be the one who keeps the documentation and the schedules, the one who keeps track of purchases and deliveries, permits, subcontractors, among other things, while the project manager plays a more role Practical and active Design of the checklist Planning a project is essential for it to be successful. The best way is to prepare a checklist before beginning the design process. The list below is exhaustive, but each project will have some unique requirements that will be it's own and should be added. It is not necessary that all steps be performed in a series. Some can be done in parallel to reduce the design time of the project. During the design of a project, the designer must communicate with several people and companies. Therefore contact...

With all these options of external plant installations, how do you start? With a good map. Not just a street map or a topographic map; A system of satellite images obtained along the streets is much better, like the one provided by “Google Maps”. Creating a street map is the first step, and you must identify the other public services on the map, along the entire route, and verify it with the groups that report on existing public services to prevent contractors from damaging the pipes and cables that are already installed. After having made the annotations on the maps, the real “fun” begins: find out who should ask for permission to lay the cables. The facilities in the external plant must have the approval of the local, provincial and state authorities, which will have a great influence on the way of designing the project. In some cities, for example, aerial cables are prohibited. Some already have underground conduits that can be used for specific paths. Since many municipalities...

The design of the fiber-optic network is the specialized process that culminates in the installation and successful operation of a fiber-optic network.  It implies determining the type of communication system / s that will be transported through the network, the geographical scope (internal plant, campus, external plant (OSP), etc.), the necessary transmission equipment and the fiber network through which equipment will work.  In addition, to design a fiber-optic network it is usually necessary to interconnect with other networks that may be connected by a copper wiring and a wireless network. Then, we must consider the requirements of permits, rights of servitude, authorizations, and inspections.  Once we reach that stage, we must take into account the selection of the components, the location, the installation practices, the tests, and the installation and commissioning of the network and troubleshooting equipment.  Finally, we must analyze the documentation, m...

There are two methods that are used to measure the loss by insertion with a light source and power meter, a "connection cable test", also called "single-end loss", according to the TIA FOTP-171 standard, and a "cable network test installed" or "loss of two ends", according to the TIA OFSTP-14 (multimode) and OFSTP-7 (single mode) standard. The difference between the two tests is that the single loss test end uses only a launch cable and tests only the connector attached to the launch cable plus the fiber and any other component in the cable. The single-end test is mainly used to test connection cables or short cables since you can test each connector individually. The two-end loss check uses a launch cable and a receive cable attached to the meter and measures the loss of the connectors at both ends of the cable under test. The single-end check is generally used in connection cables to be able to test the connectors at each end of an indi...

Run the splicing program First, choose the appropriate program for the fibers in which the splicing will take place.  The The fuser will show the fibers while splicing on a video screen. The ends of the fibers should be inspected to verify that the cuts are well made, those that are not will be rejected, and those fibers should be cut again; The fibers are then placed in position, pre-fused to remove any dirt at the ends of the fiber and to preheat the splicing fibers. The fibers are aligned using the core alignment method used in that fuser, When the fusion is complete, the user will inspect the splice and show the estimated optical loss of the splice, then tell the operator if the splice must be performed again. The operator removes the fibers from the guides and places a heat shrinkable protective sleeve or jaw protection. Fiber splicing contractor jobs Mechanical splices Mechanical splices are made with a device that aligns the ends of the two fibers and holds them to...

Shortly afterward, it was determined that polishing the splints in a convex way produced a better connection. The convex splint guaranteed that the core fibers were in contact. The losses were less than 0.3dB and the reflectance of -40 dB or even better.  The definitive solution for single-mode systems extremely sensitive to reflections, such as cable television (CATV) or telecommunications networks with a high bit rate, was to make angles of 8 degrees at the end of the splint to create what which we call an APC connector or angled PC connector. Then, any reflected light is at an angle that is absorbed in the cladding of the fiber, resulting in reflectance of less than -60 dB. fiber cable installer Color code of the connectors: From the beginning, the colors orange, black or gray were for multimode fiber and yellow for single- mode fiber. However, with the arrival of metallic connectors such as FC and ST, the assignment of color codes would be difficult, which is why commonl...

The development of new electro-optical components and integrated optics will further increase the the capacity of fiber systems. Local area network or LAN, a set of computers that can share data, applications, and resources (for example printers). Computers in a local area network (LAN) are separated by distances of up to a few kilometers and are often used in university offices or campuses. A LAN allows the fast and efficient transfer of information within a group of users and reduces operating costs. Other connected computer resources are wide area networks (WAN) or particular switchboards (PBX). WANs are similar to LANs, but they connect computers that are separated by greater distances, located in different places in one country or in different countries; They employ specialized and expensive physical equipment and lease communications services. PBXs provide continuous computer connections for the transfer of specialized data such as telephone transmissions but are not...

Wavelength Division Multiplexing Since the light of the different wavelengths is not mixed in the fiber, it is possible to simultaneously transmit signals at different wavelengths through a single fiber.  Fiber is economical, but installing new cables can be expensive, so using already installed fibers to transmit more signals can be very cost-effective. Wavelength division multiplexing (WDM) was first used with multimode fiber at the beginning of the optical fiber, using both 850 and 1310 nm in multimode fiber.  Currently, single-mode fiber networks can carry signals at 10Gb / s in 64 wavelengths or more, which is known as dense wavelength division multiplexing (DWDM).  Multimode fiber systems that use wavelength division multiplexing (WDM) have been less popular;  Nevertheless, Repeaters and optical amplifiers Although the optical fiber has low losses, which allows the signal to travel hundreds of kilometers, for extremely long distances and even on sub...

Along with the construction of global communications networks, optical fiber is widely used in the creation of local area networks (LANs). VIACOM OPTIC, a company engaged in automation and electronic technologies, designs and installs local and backbone Ethernet, Fast Ethernet, FDDI, ATM / SDH networks using optical communication lines.  VISCOM OPTIC does this for three reasons.  Firstly, it is beneficial.  When installing extended network segments, repeaters are not required.  Secondly, it is reliable.  Optical communication lines have a very low noise level, which allows transmitting information with an error coefficient of not more than 10 ** (- 10).  Thirdly, it is promising.  Fiber-optic communication lines allow you to increase the computing capabilities of the network without replacing cable communications.  To do this, you just need to install faster transmitters and receivers.  This is important for those users. A cable for con...
