Fiber optic assemblies

At IDIL, we are able to assemble, coil or terminate optical fibers of any type—whether it’s Single Mode (SM), Multi-Mode (MM), Polarization Maintaining (PM), Polarizing (PZ) or Photonic Crystal Fiber (PCF) from UV to NIR wavelengths. The use of specific optical fibers answers diverse technological needs, spanning telecommunications, sensing, medical devices, lasers, and more.

Coatings enhance the performance and durability of optical fibers in various applications. They provide protection against environmental factors, mechanical stress, and chemical exposure.

• UV-Acrylate (standard up to 85°C)
• Dual-Acrylate (high temperature up to 150°C)
• Polyimide (High temperature up to 300°C and chemical resistance)
• TEFZEL (excellent chemical resistance)
• Teflon™ (all harsh applications: temperature, chemical, corrosion, stress)
• Custom coating options on demand

Buffers and jackets are crucial components of optical fiber cables, providing protection and mechanical support to the fiber optic core. Standard fiber pigtails and jackets are either supplied with a Ø 900 µm buffer and Ø 3 mm jacket or with Ø 900 µm buffer only. Fibers without buffer (with only the Ø 250 µm coating) can be supplied. Our jackets can range between 2 and 11mm.

The polishing process is crucial for improving the quality of fiber optic connectors, particularly in terms of minimizing signal loss and maximizing performance. IDIL offers two typical polishing options:

• UPC (Ultra Flat Physical Contact, no angle): This method involves polishing the fiber end flat, without any angle. It ensures a direct, physical connection between two fiber ends, maximizing the contact area for efficient signal transmission. [Old PC (Physical Contact) are no longer used at IDIL]
• APC (Angled Physical Contact, 8° typical): This method involves polishing the fiber end at a precise angle, typically around 8 degrees. This angled surface reduces the amount of light reflected back toward the source, minimizing signal loss due to reflections.
• Others on demand

Beside flat and angled end fiber polishing, IDIL offers a large range of end fiber tips options. They allow easy fiber alignement, better coupling performance, higher power handling, precise focus spot size and working distance.

• End fiber shaping (flat, angle, cone, wedge, sphere, taper)
• Thin end caps (coreless termination fibers)
• Focusing and collimating systems
• Optical fiber splicing (standard and PCF fibers)
• End fiber coatings (anti reflection, mirror)

Lensed fibers work by adapting the mode field diameter to improve the mode matching between the waveguide and the fiber. This technology provides highly effecient couplings and collimating in a cost-effective way. The ability of getting of mode diameter which is close to 60µm leads to high positioning tolerance and high coupling ratio.

Thanks to our lenses we can get spots whose diameter is adjustable according to customers needs. In fact, since the distance between the giving out optical fiber and the lens is tunable, both the spot diameter and the working distance can be modified. Thus, the scale of spot diameter goes from values which are less than a few micrometers to some centimeters.

IDIL calculates optics by using Zemax industry standard optical system design software. We propose a global solution since we master simulation, realization and characterization processes.
