Every BIDI module consists of one transmitter and one receiver, with each working on a different wavelength spectrum, allowing two-way communication, which is important for simplex setups also. In the era of 5G, AI, and high-speed data centers, optical modules serve as the core bridge for converting electrical signals to optical signals (and vice versa), enabling fast, reliable data transmission across networks. In a fiber link, the data is transmitted from one end to another, and fiber transceivers are.
