Product Code : SCL-EELE-13238
Indian Lab Suppliers supplies the WDM Trainer With Chromatic Dispersion (Product ID: 13238) as part of its electronics engineering lab equipment range. It is a wavelength division multiplexing trainer that combines 1310 nm and 1550 nm laser channels on one single-mode fibre, with optional chromatic dispersion measurement.
Quick Answer
Two laser diodes at 1310 nm and 1550 nm, each driven by a 15-bit data generator or an external signal, are combined onto one fibre by a 2 × 1 coupler and demultiplexed at the receiving end onto two photodiode receivers with 5 V TTL comparators. Students study multiplexing and demultiplexing, send data on both wavelengths and run PC-to-PC communication over two USB channels. With the optional 25 km single-mode fibre spool, the arrival-time difference between the two wavelengths gives the chromatic dispersion of the fibre. The lasers emit invisible infrared light: never look into a connector or fibre end. It runs on 230 V AC mains.
