ULTIMODE FAST quick assembly connectors allow fiber termination with SC connectors without time-consuming gluing and polishing. The procedure does no require "sterile" conditions, because the end face of the built-in fiber fragment has been glued and polished by the manufacturer. The low loss at the level of 0.25 dB is obtained thanks to advanced positioning of the inserted fiber end by V-shaped grooves. The optical gel that is also used in the connectors reduces the effects of an imprecise cut and a possible gap between the end faces of the fibers.

A short presentation of the new series of ULTIMODE devices for testing and measuring fiber optic installations.

Mechanical splices ULTIMODE FAST-MS1 are used for permanent connections of optical fibers without the need of employing fusion splicers. Low loss at the level of 0.1 dB is obtained thanks to advanced positioning of the fiber end faces by V-shaped grooves.

The transition from copper to fiber-optic technology means the need for new tools and skills. Aside from acquiring some theoretical knowledge, installers must improve their manual skills as the work with optical fibers requires a different, more careful approach.

One of the basic criteria of optical equipment classification is the type of the fiber optics with which it works. It is connected with the type of transmission of light in the fiber core - single-mode or multimode. Transmission of light in optical fibers is based on the phenomenon of total internal reflection. The core, usually made of doped glass, is the center through which light travels along, while the fiber cladding is made of pure glass. Such combination of materials is dictated by their refraction indexes. To achieve total internal reflection, the refraction index of the cladding (pure glass) must be lower than the refractive index of the core (doped glass). The buffer coating surrounding the cladding is a cover layer usually made from a thermoplastic material and special gels, which protects the fiber from mechanical damage.

The most important task in the design of fiber optic link is to determine the maximum range of the optical transmission path, being in fact the balance of optical power in the link. Balance of power is a comparison of the power at the input of the optical link with the losses in fiber optic cables and other path components. This will help to find the optimal parameters of transmitting and receiving devices to ensure proper signal transmission.

Implementations of FTTH installations based on fiber optic subscriber lines arranged in a star topology are currently the most popular way of deploying fiber optics in multi-family buildings. The main advantages of the solution include a relatively low cost and a simple installation.

Many installers believe that fiber optics is an expensive and difficult to implement solution and don't think about it as an alternative to copper cables. They avoid to use fiber optics even in situations where application of this transmission medium seems obvious. Sometimes the investor leaves no choice - as in the case of the installer who appeared in one of our branches, obligated to install a 350-meter-long fiber optic link. After selecting the appropriate converters, we prepared the suitable optical cable with connectors. The final installation (except laying the cable) took about 5 minutes - just inserting the appropriate connectors and connecting power supply.

The main problem faced by the installer implementing video monitoring system is the choice of the appropriate type of fiber optic cable and wiring topology for the particular installation. Because the most common questions relate to installations where cameras are deployed on poles or lampposts, all the examples refer to this type of implementations, however the information is relevant to other types of installations, as well.

The article presents proposals for the comprehensive implementation of telecommunications systems in multi-family buildings, in accordance with the Regulation of the Ministry of Transport, Construction and Maritime Economy on the technical conditions to be met by buildings and their location of 06.11.2012.
