Protecting national borders requires reliable monitoring across large, remote and often difficult-to-access areas. Traditional surveillance cameras and physical patrols can have limitations in these environments. Distributed fiber optic sensing provides an additional layer of security by detecting activity along extensive sections of protected infrastructure.

On October 15, FOSS participated in an event hosted by MICOS TELCOM s.r.o., where we presented VIAVI's Distributed Acoustic Sensing (DAS) technology.

Modern military operations are undergoing a fundamental transformation. The widespread use of electronic warfare (EW) and continuous surveillance by unmanned systems place increasing demands on reliable and secure communication. Traditional radio communication can be vulnerable to detection, interference and jamming, making tactical fiber optic solutions an increasingly important part of modern defence infrastructure.

A data centre is a physical space that houses the hardware and computing systems that support a business' digital activity. Data centres store critical data and applications, such as email, databases, and customer relationship management (CRM) systems.

Roads and railways place great demands on the network's reliability. The fiber optic equipment must withstand both mechanical stress an large temperature variations. This can make standard materials unsuitable.

Rough maritime environments require products with uncompromising quality. Wet and salty environments with mechanical stress and large temperature variations can make standard materials unsuitable. The products must also be easy to install and maintain.

Industrial environments place great demands on equipment. Both mechanical stress and large temperature variations can make standard materials unsuitable.

Reliable communication is critical in defense, offshore, industrial and field applications. In these environments, fiber optic systems must withstand repeated handling, moisture, dust, temperature variations and mechanical stress.

Two terms that are often confused in fiber optics are dB and dBm. Both describe power, but there is a significant difference between them.

Digitalization is relevant in industrial environments. Equipment and processes can be remotely controlled and monitored. This places great demands on the communication equipment. Fiber optic cables are immune to electromagnetic noise and have high transmission capacity. This makes fiber optics the natural solution for modern and robust communication.

The ever increasing demand for data bandwidth has led to a massive roll-out of optical fibres in both central and rural areas of Norway. The passive infrastructure has been deployed, awaiting future technology upgrades. Point to point or point to multipoint networks, Single Family Units or Multi Dwelling Units, we have created a set of product solutions that will secure traffic stability and subscriber satisfaction. The solutions comprise ODF solutions in the ONT, outside splice closures with or without integrated optical splitters, a selection of wall boxes and products for inside optical wiring down to the OLT at the subscriber´s residence.

Since the beginning of 2017, Mesta, Norway's largest contractor in the field of maintenance and road engineering, have worked on a major upgrade with the security system in a tunnel in Bergen, Norway. To avoid closing the tunnel during the day, all work has been done by night. Because of this, it has been important to have a robust and flexible temporary safety system inside the tunnel.

ProBeam is a fiber connector designed for use in temporary connections. Originally, the system was developed for military applications, but now the industry has also discovered this very robust contact.

Wavelength multiplexing is a good and affordable method of transmitting multiple signals across the same fiber. Each wavelength (color) transports a signal. In this way, you can significantly increase the capacity of existing fiber lines. Combined with Optical Add / Drop Multiplexer (OADM), one can pick and / or add single wavelengths on the way between endpoints. A major advantage of using passive wavelength multiplexing is also that the method is protocol and speed independent.

In relatively few years, high speed internet access has become a necessity for most people in daily routines. No matter if you are working from home, watching Netflix from the couch, listening to music from Spotify or gaming online, a stabile and fast connection is needed. For years, WDM technology has been applied in order to achieve this infrastructure, at a reasonable cost and within the physical limitations that we face.

Are you in need of specialized fiber optic solutions? At Foss Fiberoptics, we have our own production facilities in Norway and Slovakia to cater to your unique requirements. With over three decades of experience, we have made locally manufactured products our cornerstone since 1984. This approach allows us to ensure quick deliveries and flexible product solutions tailored to your specifications.

Wavelength Division Multiplexing (WDM) is a technology used in fiber-optic communication to transmit multiple signals over a single fiber. WDM divides the fiber into channels with different wavelengths, allowing multiple signals to be transmitted simultaneously. There are three main types of WDM: WDM, CWDM, and DWDM, all of which increase the capacity of the fiber.

Wavelength Division Multiplexing (WDM) is a cost-effective and efficient method for increasing the capacity of existing fiber lines. This is achieved by dividing the fiber into channels with different wavelengths, allowing multiple signals to be transmitted over the same fiber. Each wavelength carries its own signal with full bandwidth. When needed, the systems can be expanded to gradually increase the transmission capacity of the line.

There are two main types of fiber for telecommunications: multimode and single mode. What are the differences between these, and when should you use single mode or multimode?

From the security point of view the structured optical cabling is evaluated only by the so called CPR classification – more details can be found in following article: https://www.fossfibreoptics.com/sk/sk/news-foss-standard-eu-cpr-cables The currently most strict class is B2ca, s1, a0, d1. CPR classification describes the performance of the cables during the fire from the fire propagation point of view, as well as the aggressivity of the generated smoke (smoke acidity) and volume of the falling burning droplets from the cable. More information about the CPR classification can be found on following link: https://eur-lex.europa.eu/legal-content/EN/TXT/PDF/?uri=CELEX:32006D0751&qid=1654675523923&from=EN
