Product Code : SCL-EELE-13280
Indian Lab Suppliers supplies the Fibre Optics Modulation/Demodulation Trainer (Product ID: 13280) as part of its electronics engineering lab equipment range. It is a single-board fibre optic trainer for studying fibre characteristics and analog and digital modulation and demodulation.
Quick Answer
Two fibre optic LEDs (660 nm and 950 nm) feed two photodetector receivers through on-board analog and digital drivers and AC amplifiers. An on-board generator gives 1 Hz–10 kHz sine waves with adjustable amplitude and an 8-bit NRZ TTL square wave, and a 4th-order Butterworth low-pass filter with 3.4 kHz cut-off recovers the signal. A voice link with microphone and speaker, an RS-232C PC-to-PC serial link on a 9-pin D connector and four switched faults are included. The 1 m PMMA fibre has polished ends for numerical aperture measurement. Analog bandwidth is 350 kHz; please confirm the digital bandwidth, the modulation schemes covered and the mains rating at quotation.
