With the advanced communication interface design, it is also suitable for applications in consumer and industrial control systems, where high-performance and reliable operation over long distances is required.

Working Principle

The working principle of ZL50019QCG1 fiber optical transceiver module is based on VCSEL and PIN technology. VCSEL is a Vertical-Cavity-Surface-Emitting-Laser. It is a reliable and cost-effective laser that emits light through an optical slit on the cavity each time the laser is triggered. In ZL50019QCG1, the VCSEL is coupled with a photodiode (PD) working in unidirectional or bidirectional mode by switching voltage from the control pins of the transceiver, which is used to convert optical signal into electrical signal.

The PIN is an optoelectronic component which converts the electrical signal into an optical signal. The PIN consists of a PIN diode, an emitter and a photoelectric transducer. The PIN diode is responsible for emitting the light when the electrical signal is transmitted. The emitter is responsible for converting the electrical signal into an optical signal and the photoelectric transducer which converts the optical signal into an electrical signal. The electrical signal will be sent to the host system once it is converted and the optical signal will be sent through the single-mode fiber.

In summary, the working principle of ZL50019QCG1 optical transceiver module is based on VCSEL and PIN technology. It features a VCSEL laser for transmitting an optical signal and a PIN for receiving a corresponding optical signal. The VCSEL converts optical signal into electrical signal and the PIN converts electrical signal into an optical signal to be transmitted over single-mode fiber. ZL50019QCG1 optical transceiver complies with IEEE802.3z 1000Base-SX and MSA standards, making it an ideal solution for fiber optic gigabit ethernet networks.
