“…The aforementioned research has shown that polarization fiber-optic sensors are increasingly utilized, especially for security technology in dangerous environments, while in some cases, they are supplemented or combined with fiber Bragg gratings [9]. Additional sources of information for the scientific results presented in this paper can be found in the literature [19][20][21][22][23], and an excellent overview of known and used sensors is described in [24]. Current measurement methods do not allow the use of polarization sensors over long distances as it is not possible to ensure the symmetrical excitation of both polarization planes.…”

The ever-increasing demands for the use of fiber-optic sensors powered by long optical fibers is forcing developers to solve problems associated with powering these remote sensors. Due to their non-electric character, these sensors are suitable for many uses, including military applications. The Army of the Czech Republic is very interested in this type of optical fiber sensor as it fulfils the significant prerequisites for use in military areas. However, the army’s requirements are challenging because they require long supply cables in which there is significant attenuation of optical power. At the same time, there is a need for high sensitivity. The subject of our research team’s work was to use amplifiers to power these sensors. The army already uses this type of sensor for short distances as it cannot ignite a gas mixture with an explosive concentration and thus meet the strict requirements of the explosion-poof standard. The novelty of our research lies in the discovered measurement technique that allows the sensors to be powered remotely and in the saving of optical fibers by utilizing duplex communication with a circulator. Furthermore, the research presents an innovative approach to the optimization of the entire sensor by using a bidirectional, sensory, polarization-maintaining optical fiber. The proposed sensor was first verified in laboratory conditions at the Optoelectronics Laboratory of the University of Defense in Brno, and further tests were carried out in the military training areas of Boletice and Březina in the Czech Republic, which is a member of North Atlantic Treaty Organization.

“…However, the security factor is still an existing challenge in such networks. The passive nature of widely deployed Gigabit Passive Optical Networks (GPONs) gives eavesdroppers the opportunity to extract sensitive information, since data in the downstream direction is transmitted to every user [7]. This highlights the need to claim quantum-level security in an end-to-end network implementation and until now, QKD has been the most efficient solution.…”

We have successfully demonstrated the integration of a commercial O-band Quantum Key Distribution (QKD) system over a testbed that replicates a carrier-grade Fiber-to-the-Home (FTTH) optical access network consisting of components and systems installed in real-life FTTH operational deployments. The experiment demonstrated a QKD transmission over a 1:16 user Gigabit Optical Passive Network (GPON) configuration at the premises of the Telecom Operator COSMOTE that followed the operator’s standard FTTH divided in two splitting stages. The architecture we implemented was a downstream access network with the quantum transmitter located at the operator’s Central Office (CO) and the quantum receiver located on the end user’s side.
