Optical Transmitter Question & Answers November 29, 2022 By WatElectronics This article lists 40 Optical Transmitter MCQs for engineering students. All the Optical Transmitter Questions & Answers given below include a hint and a link wherever possible to the relevant topic. This is helpful for users who are preparing for their exams, interviews, or professionals who would like to brush up on the fundamentals of Optical Transmitter. A device that transmits the electrical signal at a higher speed with good quality covering short distances is an optical fiber. They are used in telecommunication fields, Ethernet; and are classified as Optical transmitters and optical receivers. An optical fiber functions as a transceiver, which operates both as a transmitter and receiver. A device used at the sender end is called an optical transmitter. A device used at the receiver's end is called the optical receiver. An optical transmitter modulates an optoelectronic device. The transmitter module of optical fiber includes PS-FO-DT. The electric signal is given as input to the fiber optic transmitter selects the source, and optical energy is obtained as output from the fiber optic. 1).
