Freelance LAN Technician

And surely there will be inconveniences. All personnel involved in the project should receive instructions about safety regulations and, preferably, receive a written copy. Both supervisors and workers should have the contact numbers of the project manager, the support person and other employees they may have to contact. Because some projects require that work be done outside regular business hours, for example in the case of busy airports or government offices, where wiring is usually done overnight, During the installation itself, there must be an expert in place to monitor the progress of the installation, inspect the work, review the test data, prepare daily progress reports and immediately notify the appropriate person in charge if something does not look good. If the project manager is not technically qualified, it is important that you have someone who does have such technical knowledge. This person must have sufficient authority to stop the work or request repairs in case of...

The ways to build the OSP cables are specifically oriented to the strength of the cable, depending on whether they are buried directly or inside conductors, located underwater, or installed in the air on poles. The proper way for cable routing must be chosen. In some installations, several types of cable are even used. Having good construction plans can be useful when working with cable manufacturers to find the right types of cables and request sufficient quantities. You should always request more cable than is needed for the length of the path, in order to be able to store the service cable in the form of a loop, prepare the termination of the cable and save what you need in case it is necessary to Make a repair in the future. As well as the cable types, the cable network hardware types are very diverse and should be chosen in a way that is compatible with the cable types used. With so many hardware options, working with cable manufacturers is the most expeditious way to choose ha...

While for decades the debate about which one is better (copper, fiber or wireless network), increased interest in discussing wiring, it is now becoming irrelevant.  In communications technology and the end-user market, it seems, it has already been decided that, in general terms, the transmission media and many networks must combine all three.  Currently, for the designer of wiring networks, especially fiber optic networks, and for their clients, the task of deciding which means to use once the communication systems were chosen is very simple. Long-distance and external plant Almost all telephony system cables are fiber optic, except telecommunications systems that still use copper for the final connection to the home.  CATV companies use a high-performance coaxial cable inside homes, but it connects to a  fiber optic  backbone  network .  Backbone (  backbone  ) Internet consists of fiber in its entirety.  Most commercial buildi...

Choice of the reference method Some reference books and manuals show that to establish the reference power for loss, only a reference launch cable, launch and reception cable connected with a coupling adapter or even three reference cables is used.  In fact, industry standards include all three methods to establish a "0dB loss" reference.  The two or three-wire reference methods are acceptable for some tests and are the only way you can test some connectors, but it will reduce the loss you measure in the amount of loss between your reference wires when you set your "  You could start the test with faulty launch wires, which would cause all loss measurements to be incorrect.  This means that the inspection and testing of the reference cables are very important, in order to ensure that they are in good condition.  You could start the test with faulty launch wires, which would cause all loss measurements to be incorrect.  This means that the inspection and...

The choice between fusion or mechanical splices can be made according to different parameters, including performance, reliability, and cost. In addition, installers can choose the type of splice with which they are most familiar or who already have the equipment to do it. From the point of view of performance, fusion splices provide low losses and low reflectance, so they are preferred for single-mode networks. Fusion splices may not work well on some multimode fibers, so mechanical splices are preferred for multimode connectors unless it is an underwater or aerial installation, where the security provided by fusion splices is preferred. From the point of view of reliability, fusion splicing is the best choice. When done well and secured with a protective sleeve, the splice can last the same as the cable. Some studies have shown that mechanical splices are also durable, but they do not have the mechanical strength of fusion splices. Fiber optic certified If the cost is a prob...

Most connectors have epoxy resins or other adhesives to keep the fiber inside the splint of the connector and a fine polishing of the fiber end for a smooth finish. Follow the termination procedures carefully, as they have been developed to generate the lowest losses and the most reliable terminations. Use only the specified adhesives, since fiber bonding to the splint is vital to achieving lower losses and long-term performance. We have seen people using epoxy adhesives from hardware stores, cyanoacrylate, among others, but then they repented.    Only those adhesives approved by the manufacturers or distributors of the connectors can be used. If the adhesive does not work, something that is not so unusual when the splints of the connectors are made of metal, the fiber "pistons" (protruding from the splint or retracting), which causes high losses and possible damage to the coupled connector. The polishing process takes three steps but only takes a minute: "polish ...

Fiber optic joints or terminations are made in two ways:  1) with connectors, which join two fibers to create a temporary joint and/or connect the fiber to network equipment;  or 2) with splices, which create a permanent bond between two fibers.  Both termination methods must have two main characteristics:  good optical performance, determined by low attenuation and minimal reflectance, and high mechanical strength.  The terminations must also be of the appropriate style so that they are compatible with the equipment used and are protected from the harmful effects of the installation site. It is likely that no fiber optic component has been given as much attention as the connector.  Manufacturers have developed more than 80 types of connectors and about a dozen different ways to install them.  There are only two types of basic splices but several ways to implement them.  However, manufacturers and installers are fortunate since, in most instal...

The fiber optic cable provides the fiber / s inside the appropriate protection for the installation site.  When we say "cable" we mean the complete assembly of the fibers, the reinforcement elements, and the jacket.  Fiber optic cables are of different types, depending on the number of fibers, the model and the place of installation.  It is important to choose the cable carefully as that will determine the ease with which the installation will be done, the splicing or termination of the cable, the cost of the cable and the duration in the field. The function of the cable is to protect the fibers from the effects of the environment in the place where they are installed.  Outdoors, it depends on whether the cable is directly buried, inserted into underground conduits, suspended in the air or even installed underwater.  Will the cable get wet or wet?  Should it withstand high tensile stress when installing in underground ducts, or continuous tension when i...

The history of fiber optic communication is relatively short.  In  1977  , a test system was installed in England;  Two years later, significant quantities of orders for this material were already produced. Earlier, in  1959  , as a derivation of studies in physics focused on optics, a new use of light was discovered, which was called a laser beam, which was applied to telecommunications in order for messages to be transmitted to unusual speeds and wide coverage. However, this use of the laser was very limited because there were no suitable conduits and channels to travel the electromagnetic waves caused by the rain of photons originating from the source called laser. It was then that scientists and technicians specialized in optics directed their efforts to the production of a duct or channel, known today as the optical fiber.  In  1966  , the proposal to use an optical guide for communication emerged. This way of using light as an...
