Optical transceivers are key optoelectronic devices in fiber optic communication systems, responsible for converting between optical and electrical signals. They play a crucial role in modern communication networks, especially in areas such as data centers, telecommunications networks, Fiber to Home (FTTH), and high-speed data transmission.

Optical Transceiver
The main function of the optical transceiver is to convert electrical signals into optical signals at the transmitting end and transmit them through optical fibers; At the receiving end, it converts the optical signal back into an electrical signal. This conversion process allows data to be transmitted over long distances and at high rates, while reducing signal attenuation and electromagnetic interference.
Optical transceivers typically consist of the following main components:
Transmitter Optical Subassembly: including lasers (such as DFB lasers, VCSEL, etc.), responsible for generating optical signals.
Receiver Optical Subassembly: including photodetectors (such as PIN photodiodes, APDs, etc.), used to detect optical signals and convert them into electrical signals.
Functional circuit: including driving circuit, amplification circuit, modulation and demodulation circuit, etc., used to control the generation and reception of optical signals.
Optical interface: used for connecting with optical fibers, usually including fiber optic connectors (such as LC, SC, MPO, etc.).
Applications
Internal server connections within the data center
long-distance fiber optic transmission
fiber optic backhaul links for wireless base stations
fiber optic access networks for households and enterprises.
