Specialized laser source - continuously tunable laser for transmission in the telecommunication band C (1 pc), allows to transmit superstable optical frequency from optical atomic clock over optical photonic network at wavelength selectable in wide range and it will be possible to fully test the behavior of photonic network for very wide wavelength range in telecommunication band C.
The role of the optical phase modulators is to derive a control signal to stabilise the optical frequency of the laser, enabling the interferometer to make extremely precise measurements.
