Single fiber modules (BiDi) use one fiber for both transmitting and receiving data. Its primary function is to achieve optoelectronic conversion by converting electrical signals into optical signals and vice versa. Optical modules typically have an electrical interface on the side that connects to the inside of the system and an optical interface on the side that connects to the outside. Transmit power is the power at which the transmitter of an optical transceiver module transmits optical signals in dBm. Operating at the physical layer of the OSI model, optical modules are core devices in optical. Optical modules are a core component of optical fiber communication systems. Figure 2-64 shows the structure of an optical module.
