Optical transceivers (optical modules) are core photoelectric conversion components in fiber-optic communication, data centers, enterprise networks, and telecom transmission systems. Today we will learn and explore the working principle of the optical transceiver.

What Is an Optical Transceiver (Optical Module)?

Due to the development of microelectronic technology, active and passive optical devices technology, optical transceiver has become the mainstream of the common optical module in recent years. Although the optical module package, rate, transmission distance is different, but its internal composition is basically the same. 

Optical module is a carrier for the transmission between the switch and the device, is the core device in the optical fiber communication system.The main function is that the transmitting terminal converts the electrical signal of device into an optical signal.

So we can conclude that the role of optical modules can be understood as a transfer device of the transmitting and receiving signals, is a bridge for the transmission of electrical signals. ETU-Link provides all of the optical module types mentioned in the text, complete models, low loss, cost-effective. In addition, we also provide OEM customized services to meet your different needs.
