Proximion's Dispersion Compensation Modules use a long, chirped Fiber Bragg Grating to reverse the chromatic dispersion that affects long-haul fiber network links. The dispersion correction is continuous across the full spectrum and so is channel independent.
With a Proximion DCM added to a network, error-free higher data rates are enabled.
The same chirped Fiber Bragg Grating technology used in a Proximion Dispersion Compensation Module can be used to create a custom Dispersion Emulation Module (DEM).
Such a custom DEM creates the chromatic dispersion effects of a specific long fiber network and enables a network designer to develop and test the complex DSP algorithms needed for chromatic dispersion management on that network.
Proximion has combined the features of an optical spectrum analyzer and a fast optical channel monitor within WISTOM, the market's most advanced optical layer monitoring product series.
WISTOM allows operators to monitor their networks for performance and security compromises in real time.

Since 2015, Proximion has been involved in a strategic contract with a Tier1 airframer to supply advanced fiber optical sensors to the aerospace industry based on Proximion's proprietary FBG design and manufacturing technology.
Proximion's cryogenic monitoring capabilities are also being used in the development of future green aircraft fuelled by liquid hydrogen.
Proximion are supporting SKF AB with the development and manufacture of fiber optic load sensing integrated into bearings to support the SKF promise to offer reliable rotation to its customers.
Proximion has developed a unique capability to measure distributed temperatures as low as 20 Kelvin, a capability which is being used in the process and storage of liquid fuels.
The electromagnet immunity and non dielectric benefits of Proximion’s technology unlocks use cases it the condition monitoring of the electrical windings or motors, generators and transformers.
In certain applications, it is often required to amplify the narrow, high amplitude output of a laser. Such amplification is far easier to achieve if the laser power is first spread into a broader, lower amplitude spectrum.
This can be conveniently done with two chirped FBGs before and after the amplifier, as shown to the right.
Microwave photonics is a rapidly developing field that combines photonic devices with high-speed electronics in microwave system applications.
Photonic devices enable the implementation of new functions in microwave systems by utilizing the broad bandwidth, high frequency, and low loss offered by modern photonics. CFBGs can be utilized in developing high-performance microwave photonic filters, ultrafast optical pulses, and time delay beamforming.
Quasi-distributed strain and temperature sensing is performed with arrays of different wavelength FBGs at discrete positions. However, in some circumstances a truly distributed measurement is required. Proximion has demonstrated how its long, continuously chirped FBG can provide high resolution distributed strain and/or temperature measurement along its length.
Infra-red spectroscopy identifies the chemical composition of sample matter by analysing the absorption of different light wavelengths. Traditional IR spectrometers can be expensive and sensitive to environmental factors.
An alternative method of time stretched spectroscopy, where the spectral information is encoded into a time series by a long CFBG and then decoded by a single fast photodetector, offer a low cost and highly robust spectrum analyser.
Optical Coherence Tomography (OCT) is a key technique for medical research. OCT benefits from fast imaging and speed increases have been gained using rapidly tuned mechanical optical filters, but to achieve the target speeds of 10 MHz non-mechanical tuning is required.
A Proximion chirped FBG has been proven to be a suitable part of a 9.4 MHz pulsed 1300 nm source of a stretched-pulse active mode-locking (SPML) OCT.
