Provis has a highly experienced fiber optic installation team and, with this team, provides active and passive fiber optic product supply and installation services for the most sensitive fiber optic projects, primarily domestically but also internationally.

With the expertise gained from field application experience in fiber optic work since 1994, we offer fiber optic cabling services with high workmanship quality and lossless speeds.

WHY SHOULD FIBER OPTIC CABLES BE PREFERRED?
1-Wide Band Range:
Fiber systems have greater capacity because optical frequencies, by their nature, provide wider bandwidths. In metallic cables, capacitance occurs between conductors and inductance occurs along the conductors. These properties cause metallic cables to act like low-pass filters, limiting their bandwidth.
2- Low Cost Per Channel:
The fact that cables are lightweight and inexpensive, the bandwidth is high due to the distance multiplier, repeater intervals are long, and the number of channels can be increased by switching active devices, reduces costs. Compared to copper conductors of the same capacity, the communication cost per Mbps is cheaper.
3- The Difficulty of Stealing Information:
To steal information from an optical fiber cable, it would be necessary to cut the cable and connect it to the system. Such a method would be detected immediately.
4- Unaffected by Electromagnetic Interference:
While copper conductors and other transmission systems are susceptible to magnetic interference, optical transmission does not experience this. Even if a fiber optic cable is run alongside high-voltage conductors, the energy cannot negatively affect the fiber optic cable, and communication problems will not occur.
5- Absence of Interference (Cross-phony):
In optical transmission, signals do not spill outside the fiber core. Fiber optic cables are unaffected by static interference caused by lightning, electric motors, fluorescent lights, and other sources of electrical noise. While this causes signal interference, known as crosstalk, in copper cables, even if signals spill outside the core due to bends, they do not enter and affect other cores. Therefore, there is no interference. One reason for this is that fiber optics do not conduct electricity. In addition, fiber cables do not radiate energy; therefore, they cannot cause interference with other communication systems. This feature makes fiber systems very suitable for military applications.
6- Electrical Insulation:
Since optical fibers are made of electrically insulating materials, they provide complete electrical insulation between ends. Furthermore, they do not produce sparks upon breakage or interruption. This feature makes fiber optic cables ideal for safe communication in environments containing explosive or flammable materials, and they are also very suitable for narrowband systems and closed-circuit television systems.
7- Adaptability to Different Environmental Conditions:
Fiber conductors resistant to heat and extreme cold (up to +500°C) have been manufactured. Therefore, they can be used safely in environments where copper conductor cables cannot be used.
8- Facility Amenities:
Fiber optic cables are easy to install due to their small diameter (a 12-core cable has a diameter of 17mm) and light weight. For example, the copper conductor (0.6mm2) has a fiber core weight of 3kg/km (0.05), resulting in a splice density of ±0.05km, 4 ±0.05 or 2 ±30-50gr/km. The long reel lengths (1.5) reduce the number of splices, allowing many cables to be pulled through the same mesh due to the small cable cross-section. Despite the ease of cable installation, the materials used for splicing and maintenance are quite expensive, so installation and splicing must be done carefully by experts.
9- Use in the Local (Subscriber) Distribution Network:
With the advent of ISDN* applications, fiber optic cables can now be installed all the way to the subscriber's home. Countries such as Sweden, Germany, France, and the United States, where ground-mounted wiring and cable distribution are widely used, have begun pilot applications of Local Area Networks (LANs) and are implementing fiber-to-the-home applications. Subscriber loops have also been used in Japan since 1984.

APPLICATIONS OF OPTICAL FIBERS:
Optical communication systems have quickly found widespread use due to the great opportunities they offer. Various areas where these systems are used are listed below:
1. In long-distance, high-capacity communication systems and medium-distance, low-capacity systems due to low attenuation, large bandwidth, and low cost per channel,
2. Especially in inter-exchange connections because it allows both analog and digital transmission and provides broadband service,
3. In indoor transmission systems (with plastic fibers) due to low loss and high speed,
4. In closed-circuit television systems,
5. In data transmission,
6. In connecting electronic devices to each other,
7. In the aviation field (radars), in inter-device and aircraft interior equipment requiring high speed,
8. In railway electrification and signaling applications,
9. By placing fiber optic strands inside high-voltage conductors, the conductors can carry energy while simultaneously providing communication,
10. In traffic control systems,
11. In military communication systems,
12. In billboards,
13. In medical devices,
14. In nuclear power plants and radioactive radiation... where it disrupts communication,
