KIT Wavelength Multiplexing (WDM)
Product description
A new generation of fibre optic transmission systems have appeared in the 90’s, using the wavelength multiplexing/demultiplexing techniques (WDM).
The idea is to inject simultaneously different wavelengths in the same fiber, increasing the data transmission capacity of a single fiber.
This WDM kit, coupled with the erbium doped fiber amplifier, allows the experimental study of the behaviour of an erbium doped fiber amplifier, working in multiwavelength mode.
Components included
| Option: it is also possible to add a circulator and a fiber Bragg grating, in order to make an Add-Drop multiplexer. |
| 1 source module composed of |
| 4 DFB laser diodes @ 1535, 1543, 1550 and 1560 nm, 1 mW, CW or analogical modulation (100 kHz) |
| 1 optical isolator |
| 6 Patchcords E2000/PC Diamond connectors |
| 1 fiber optic coupler 1×4 |
