Optical channel generator
LIGENTEC is offering an optical channel generator with customisable channel spacing ranging from 20-200 GHz. The device generates more than hundred optical channels covering the entire C and L communication band.
LIGENTEC channel generator is an optical frequency comb with microwave repetition rate integrated in a rack mountable device and is a compact solution for telecommunication test & measurement laboratories.
Advantages and properties:
- Customizable mode spacing (20-200 GHz)
- More than 300 channels
- Femtosecond pulsed output (< 100 fs) with high repetition rate (20-200 GHz)
- Power per line is at -15dBm with optional amplification
Our optical channel generator can be used for coherent terabit telecommunication. It was demonstrated and published that a frequency comb generated from a silicon nitride resonator can be modulated to encode hundrets of Gbit/s. Especially the linespacing of the comb lines of tens of gigahertz is promising for telecommunication.
