Custom Electrical Filter Designs

From Thin Film Technology Corporation
 

 
Thin Film Technology (TFT) is a high-speed passive component manufacturer who can provide you with custom electrical filter designs for your optical system designs. In addition to the custom filter design work, we also carry a standard set of enhanced duo-binary electrical filters for your immediate needs. Thin Film Technology will work with you to provide a fast electrical filter network design for your front or back end optical application. One of our specialties is the concept and design of an "Enhanced Bessel" Filter for Duo-binary modulation type schemes for the front end of the optical system. Optical Duobinary systems with conventional electric components (NRZ Driver) require a low drive voltage modulator and an electrical filter that exhibits good return loss and group delay performance. At the back end of the electro-optical system there is an issue of tuning the receiver sensitivity to optimize for the spectral content of the data. TFT also provides the electrical filtering solutions to help minimize the high frequency noise content after the trans-impedance amplifier to improve the eye opening.
