Fiber optic transceiver

A fiber optic transceiver is a device capable of both transmitting and receiving optical signals in a fiber optic network. Fiber optic transceivers facilitate bi-directional data transmissions between electronic devices (e.g., computer, input/output system, peripheral device, or switch) and optical data links in fiber optic systems. Fiber optic transceivers interface with optical fibers for transmitting light signals thereto, typically through a light-emitting diode (LED) or like device responsive to electrical excitation to output light pulses corresponding with digital signals providing the information for such excitation. The transceiver receives and emits light beams perpendicular to its top surface. Since the fiber cable is connected normal to the computer back face as other communication cables, the planar optoelectronic semiconductor preferably has a first distinct orientation which is perpendicular oriented to the circuit board. The two most basic electronic circuits within a fiber optic transceiver are the laser driver circuit, which accepts high speed digital data and electrically drives an LED or laser diode to create equivalent optical pulses, and the receiver circuit which takes relatively small signals from an optical detector and amplifies and limits them to create a uniform amplitude digital electronic output. The optical transmitters and receivers are usually packaged as individual components, commonly known as transmit optical sub-assemblies (TOSAs) and receive optical sub-assemblies (ROSAs), respectively. he fiber optic transmitter component typically includes a laser, a lens assembly, and a circuit for driving the laser. The fiber optic receiver component typically includes a photodiode and a high gain receiver amplifier.
