FFA-01 is a fiber array sensor with configurable number of FBG elements and their spacing over the fiber length. FFA-01 is typically used for direct gluing to the measured surface to capture strain changes of the monitored structure.

SYLEX proudly introduces our latest innovation: high-precision fiber array assemblies, expertly crafted for the photonics industry and perfect for connecting with photonic integrated circuits (PICs). Our fiber arrays come with options for both standard fibers and polarization-maintaining (PM) fibers, ensuring exceptional performance for specialized applications.

Fiber end caps, spliced onto optical fibers terminated in FO connector, ensuring reliable data transmission by minimizing reflections and maintaining a consistent refractive index. Their coreless design allows light to expand evenly within the material. They provide high-power protection by reducing intensity at the fiber face, preventing damage from high-power sources. In photonic crystal fibers, end caps prevent water ingress. End caps are essential for fiber-optic sensors, high-gain fiber amplifiers, and protecting laser delivery fibers.

SYLEX specializes in high-quality optical interconnect solutions and fiber optic sensing/monitoring solutions. Our Fiber Optic Interconnection Division serves telecom, datacom & LAN, on-board optics, general industry, defense, aerospace, and harsh environments.

SYLEX offers automated monitoring solutions based on advanced FBG technology, essential for monitoring structural health and operational conditions in industries like civil engineering, geotechnical fields, energy, transportation, chemicals, oil & gas, and process control. We also produce OEM and custom FBG sensors, partnering with research and development entities as a small and medium enterprise (SME).

We have enhanced our production with equipment for angle polishing of optical fibers, supporting both individual fibers and ribbon structures. This enables us to meet custom requirements across various fiber optic assemblies.

The equipment allows polishing angles from 0° to 45°, reducing back reflections and improving signal integrity where angled end-faces are needed.

We process ribbon fibers with 8, 12, or 16 fibers, used in high-density interconnects, optical transceivers, and PIC packaging. Polished ribbon ends ensure low insertion loss and high consistency for fiber arrays and multi-channel interfaces.

Polished individual fibers are used in optical sensing, aerospace, R&D, and test setups, where angled polishing optimizes return loss and interface performance.

This in-house capability gives us full control over the polishing process, offering custom-tailored solutions for standard and non-standard configurations, even in low to medium volumes.

Flexible optical fiber circuits optimize complex optical fiber routing with high fiber counts, addressing fiber management issues. Features include high fiber count in racks or on PCBs, flexibility, and lightweight design for SM or MM applications. The Optical Fiber Flex circuit, an Optical Circuit Board (OCB), accommodates numerous fibers and FO connectors, varying in shape, size, and thickness. Components are fixed on Kapton polyamide layers, using primary coated fibers of ≤250 µm. These devices are suitable for telecom satellites and other harsh environment applications.

Fiber Bragg grating sensors are commonly used in structural deformation and temperature monitoring. Short-period fiber grating sensors are commonly used, and their reflection wavelengths are called Bragg wavelengths. Such sensors are called FBG sensors.

FBG based displacement sensors are used to measure the amount of movement that occurs between an object and a reference position. The displacement sensor can be used to measure amplitude to determine the height, thickness, and width of an object in addition to the range of motion.

FBG based pressure sensor is a device or instrument which is able to measure the pressure in gases or liquids. A pressure sensor consists of a pressure-sensitive element which can determine the pressure being applied and components to convert the information into an output signal.

Sylex offers FBG-based optical humidity sensors for the relative humidity (RH) of air or the amount of water vapor present in gas mixture.

An optical interrogator, also known as measurement unit or data acquisition system, is an optoelectronic instrument, which allows the reading of optical fiber Bragg grating (FBG) sensors in static and dynamic monitoring applications.

FBG based strain sensors are devices that are commonly used by engineers to measure the effect of external forces on an object. They measure strain directly, which can be used to indirectly determine stress, torque, pressure, deflection, and many other measurements.

FBG based temperature sensor is essentially a device used to take accurate temperature measurement readings.

Plastic optical fiber (POF), made from polymer, transmits light through its core, similar to glass optical fiber. POF typically has diameters between 0.25 mm and 1.5 mm and is often terminated with a probe or threaded tip on the sensing end. Plastic fiber optics are more flexible, less expensive. They are suitable for tight spaces and can be cut to length in the field. They can also be easily assembled to fit specific applications, making them versatile for various uses.

Polarization optics ensure stable signal transmission by preserving light polarization. SYLEX offers PM jumpers, fiber arrays, and PANDA-based interconnects with FC, LC, SC, and MU connectors. Ideal for interferometers, modulators, and PICs, these solutions deliver low insertion loss and high PER for demanding photonic applications.

Polarisation-maintaining fibers (PM fibers) are used in specific applications where the polarisation effect (maintaining signal polarisation state) plays a major role and directly influences the functionality of the whole system. PM fibres are typically used in interferometers, sensing solutions (gyroscopes and accelerometers) and modulators in combination with laser sources considered for transmitters designed for on-board optics solutions.
