Product description:
This device closely combines the reality of modern optical fiber communication, fully reflects the current condition and development trend of optical fiber communication, and is the best choice for students to combine theory with practice. This experimental system can be used for experimental teaching in communication, optoelectronics, optics, electronics, physics and other related majors, so that students can understand the principle of optical communication and lay the foundation for further study and work in the future.
System composition:
1. Using high-performance single-chip 89C52 as the system controller, 4×4 keyboard matrix realizes the working state setting, and realizes the working state and parameter display with LCD192×64.
2. Each of the 1310nm and 1550nm optical transmission units has two analog and digital switching switches that can transmit analog and digital signals.
3. Two optical receiving units, each with one analog and digital switch, and functional switch and jumper for receiving analog and digital signals.
4. Two telephone interfaces, with analog and digital switchers for voice telephony transmission.
5. There are two-way RS232 level conversion circuit and RS232 standard interface to realize data transmission between computer and MODEM.
6. A 1 × 2 single-mode optical splitter that can achieve 1 input and 2 output of optical signals.
7. Using CPLD device EPM7128 and serial digital-to-analog converter TLC5620, and analog
