Fiber-optic technology in CCTV systems - practical issues
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.
FTTH - distribution methods in buildings
FTTH networks make an important part of modern telecommunication installations in residential buildings and other multi-dwelling units. The growing popularity of fiber optic systems "in the last mile" is the consequence both of legislation adopted in many countries and a growing awareness of investors. Fast and reliable access to the Internet and multimedia services has become a priority. The popularization of optical fibers is also possible due to cheap and effective technological solutions. Internet service providers have noticed the advantages of passive optical networks (xPON).
FTTH - installation of a distribution frame/box
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.
SignalNET - telecommunications and RF distribution systems in multi-dwelling units
The article introduces concepts of implementing integrated telecommunications and RF distribution systems in multifamily buildings, which are compliant with new regulations in Poland. Similar regulations apply or will apply in other EU countries.
Easy access cable - installation of distribution frame/box (example)
The article presents an example of terminating FTTH network based on the so-called easy access cable. Currently, the use of easy access cables is the optimal solution for installing fiber-optic cabling in buildings.
Fiber-optic TV systems
Under EU rules, by 2020 each citizen of the European Union is to have the technical ability to access the Internet with download speed at least 20 Mbps. In this respect, some EU countries introduced regulations aimed at accelerating this process. In some of them, each newly built residential building should be equipped with fiber-optic infrastructure. This type of cabling can be used not only in the implementation of access to high-speed Internet, but also proves to be an excellent medium for other services, including distribution of TV/SAT programming. Multiswitch systems providing access ...
Optical fibers go into homes - how to join them
Systems based on optical fibers are becoming increasingly popular. General availability of comparatively cheap devices converting electrical signals to optical form and vice versa, combined with the advantages of optical transmission, especially very wide band, galvanic isolation between devices and no problems with implementation of long links, are the main reasons for the wider and wider use of this technology in LANs, analog and IP video surveillance systems, S/MATV installations and even in alarm systems. The latest regulations of the construction law in many countries, e. g. in Poland, ...
Mechanical splicing of optical fibers - ULTIMODE FAST-MS1
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.
Multimode and single mode fiber-optic cables
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 ...
Fiber optics in homes in a few simple steps
After many years of the presence of optical fibers in the telecommunications market, it's about time they got settled in houses and apartments. It is forced by the rate of technological progress of consumer electronics that increasingly offers its services on the basis of network connections and online applications.

Optical power budget in a fiber-optic communication link
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.
How to terminate fiber with ULTIMODE FAST connectors
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.
Fiber-optic SMATV systems
Optical RF signal transmission allows for long-range distribution of digital terrestrial and satellite television, DAB radio, security video etc. Fiber-optic SMATV systems provide much more flexibility compared to those based only on coaxial cable.
Optical fiber standards
With the great popularity of optical links in the last few years, the main part of them is currently based on modern single-mode fibers. However, both single-mode and multimode fibers are divided into many types/categories that comply with established standards and factory specifications.
ABC of working with fiber optics for beginners
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.
CCTV over fiber - simple, cheap and reliable technology
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 ...
