Fiber-Optical communication package as one part of electronic packages,is used by many telecommunications companies to transmit telephone signals,Internet communication and cable television signals.Due to much lower attenuation and interference,optical fiber has large advantages over existing copper wire in long-distance and high-demand applications.Modern fiber-optic communication systems generally include an optical transmitter to convert an electrical signals into an optical signals to send into the optical fiber, a cable containing bundles of multiple optical fibers that is routed through underground conduits and buildings,multiple kinds of amplifiers, and an optical receiver to recover the signal as an electrical signal.The information transmitted is typically digital information generated by computers,telephone systems, and cable television companies.


The most commonly used optical transmitters are semiconductor devices such as light-emitting diodes(LEDs)and laser diodes.The difference between LEDs and laser diodes is that LEDs produce incoherent light,while laser diodes produce coherent light.For use in optical communications,semiconductor optical transmitters must be designed to be compact,efficient,and reliable,while operating in an optimal wavelength range, and directly modulated at high frequencies.Baienwei adopts rapid solidification and subsequent machining technology, offering a series of electronic packaging services,including R&D,production,subsequent machining and plating.We serve exclusive and customized services according to customers’ industry attributes.
