- Light Sources: light-emitting diodes (LEDs) and laser diodes are commonly used as light sources in optical communication systems
- Optical Fibers: step-index and graded-index fibers are used to transmit light signals
- Optical Amplifiers: optical amplifiers, such as erbium-doped fiber amplifiers (EDFAs), are used to amplify weak light signals
- Optical Receivers: photodiodes and avalanche photodiodes are used to detect light signals and convert them back into electrical signals

power budget
Gowar flips the script. He introduces the and rise-time budget within the first 100 pages. He forces the reader to ask the engineering question: “Given a transmitter and receiver, how far can I send data?” This top-down approach is pedagogically superior. You learn the physics because you need it to solve the budget, not the other way around. Gerd Keiser | Textbook | Strength | Weakness

fundamental operation
Though decades old, the book remains a valuable reference for those needing to understand the of optical sources, detectors, and receivers. It is often cited as a self-contained guide that complements more introductory modern texts.
