Will new customers always ask for a pair of optical transceivers? Yes, in fact, optical transceivers are used in pairs. Optical transceivers are used in optical and electrical converters that use optical fibers as the carrier. The sender and receiver must be the same device.

Why should optical transceivers be used in pairs?

Simply put, an optical transceiver is a terminal device for optical signal transmission. In fact, an optical transceiver is an optical fiber communication device that extends data transmission. Optical transceivers are generally used in pairs, divided into optical transmitters and optical receivers.
The optical transmitter completes the electrical-optical conversion and transmits the optical signal for optical fiber transmission.

The optical receiver mainly restores the optical signal received from the optical fiber to an electrical signal to complete the photoelectric conversion. Therefore, optical transceivers are generally used in pairs.

There are many types of optical multiplexers: PDH optical multiplexers, telephone optical multiplexers, SDH optical multiplexers, SPDH optical multiplexers, video optical multiplexers, Ethernet optical multiplexers, audio optical multiplexers, data optical multiplexers, VGA/HDMI optical multiplexers, HD-SDI optical multiplexers.

The function of the optical transceiver is to transmit data remotely, and to transmit audio and video over a long distance. It has the advantages of long transmission distance, no delay, no interference, etc.
