With 59 Gratings-related patents, OFS is a leader in the creation and production of fiber Bragg gratings. We offer a full array of FBG types, such as Stablizer gratings, High Reflector Gratings, Wide Band gratings, Long Period gratings, and Fiber Arrays. We’ve developed capabilities for write-through coatings, where the acrylate does not need to be stripped from the fiber in order to write a grating, and we’ve recently developed the ability to write gratings in high-temperature fibers coated with our proprietary high-temperature PYROCOAT™ polyimide.

The rapid increase in the demand for greater transmission capacity, DWDM has emerged as the key transmission technique. There is continuous pressure to increase the number of DWDM channels and this in turn calls for improved performance from the passive multiplexing components.

The device covers wide wavelength ranges and provides simultaneous measurements at very fast response rates and excellent wavelength resolution. High reliability (MIL STD 810E shock and vibration) is achieved through a rugged mechanical design with no moving parts. Periodic calibration is not required. Input/Output (I/O) is provided through a dual port RAM interface accessed through ADD/DAT bus direct connection or serial (RS232 or USB) communications
The WaveCaptureTM FBGA Series employs a highly efficient Volume Phase Grating (VPG®) as the spectral dispersion element and an ultra sensitive InGaAs array detector as the detection element, thereby providing high-speed parallel processing and continuous spectrum measurements. As an input, the device uses a tapped signal from the main data transmission link through a single mode fiber, then collimating it with a micro lens. The signal is spectrally dispersed with the VPG®, and the diffracted field is focused onto an InGaAs array detector. The control electronics read out the processed digital signal to extract required information. Both the raw data and the processed data are available to the host.
