Used book platforms like Amazon, AbeBooks, or ThriftBooks often have affordable physical copies of the second edition. The concept of using light for communication dates
Optical communication systems use light to transmit data through optical fibers or free space. The concept of using light for communication dates back to the 1960s, but it wasn't until the 1980s that the technology started to gain traction. Today, optical communication systems are a vital part of modern telecommunications infrastructure, enabling fast and reliable data transfer over long distances.
Older editions or used copies are often available through online platforms (e.g., Amazon, AbeBooks) at a lower cost, which provides the full, legal text. with several emerging trends and technologies
According to an IEEE review, the book is an excellent text for upper-level undergraduate or beginning graduate work in electrical engineering, applied physics, or related disciplines. It is considered timely and appropriate for students entering the rapidly expanding field of optical communications. One user noted it's "a good book to learn basics of optical communication," helping them solve problems regarding Maxwell's Equation and Snell's law.
The future of optical communication systems looks promising, with several emerging trends and technologies, including:
Archive platforms occasionally host out-of-print editions legally for educational lending.
The book is divided into 10 chapters, each focusing on a specific aspect of optical communication systems.
