experiment; CMI、5B1C、5B6B scrambling and descrambling other circuit coding functions; the
multiplexing and demultiplexing functions, signaling functions and systemic experimental
functions are enhanced, and the phone call connection system experiments between
platforms can be achieved under the support of signaling. Added color touch LCD keyboard
control, DDS signal and frequency selection, experiment content selection, BER tester
settings and bit error statistics and other functions can be realized with the keyboard; Optical
input and output interfaces are all designed outwards. It is suitable for college students, undergraduates, postgraduates, teachers and related scientific and technical users in all
major colleges and universities.
Technical parameter
1. Three pairs of optical transceivers: 1310, 1550, 850 one pair for each (850 for multi-mode, optional accessory); no light alarm, automatic power control APC, extinction ratio test, PI curve test, average lighting power test, Optical transceiver receiver sensitivity test and other experiments can be done by optical transceiver module. 2. 1310 is of transceiver type; 1550 is made of LD laser and LD light detector and discrete components; 850 is made of LED light emitter, detector and discrete components;
experimental box optical transceiver is fully configured. Both integrated optical transceivers and optical transceiver modules composed of discrete devices are included; Both digital optical transceiver module and analog optical transceiver module end are included; Both single-mode optical fiber transmission module and multi-mode optical fiber transmission module are included.
3. The experiment box source to electrical interface, electrical interface to optical interface, and optical interface to optical path are separated, which is helpful for students to understand the communication system;
4. Two telephone interfaces, a computer USB serial port, a network interface, a switch setting port, a signaling interface, can perform time division multiplexing of different data sources. PDH data time slots can be set by the PC;
5. With a standard E1 interface, line clock is programmable (from 1 to 32 time slots, namely 64KHZ --- 2048KHZ programmable), multiplex data time slot can be configured by PC.
6. Built-in color touch LCD and keyboard, you can make experiment content selection, data setting and data display through human-machine dialogue;
7. The built-in telephone time division switching function of the experimental platform can realize the functions of dialing numbers and calling with 4 parties via the optical fiber between the telephone users (experimental platform);
8. The secondary development such as optical communication channel encoding, USB data communication, network data transmission, optical receiver digital phase-locked loop, fault code detection, and optical network construction can be carried out.
9. Built-in DDS signal source is convenient for students to complete the LED and LD optical transceiver analog signal and video signal transmission experiments;
10. Built-in full-function BER tester module, clock, pattern, inserted bit error, etc. can be selected and time, bit error ratio and so on can be couted by touch LCD, with high cost performance (photometric receiver sensitivity and optical device insertion loss, etc.)
11. SDH teaching analysis software is provided, which can perform experiments such as SDH overhead byte observation experiment, SDH high order channel overhead byte observation experiment, SDH low order channel overhead byte observation experiment, SDH frame
multiplexing and positioning, etc.;
