TeraTone™ Low Noise Frequency Comb

TeraTone Low Noise Frequency Comb


Narrow-linewidth, high-OSNR, coherent tone bank with 100-GHz tone spacing


The TeraTone™ low-noise frequency comb is the first multi-wavelength source providing more than 100 carriers over the continuous C+L band with inherent low phase noise on all of the carriers. Driven by patented technology, the TeraTone low-noise frequency comb is a high-performance, energy efficieny source for telecomm and datacom systems, particularly for coherent modulation schemes.

High OSNR across entire C+L


Carriers can be projected over any ITU channel grid, with kHz-­level linewidth and 1000‐fold better frequency stability than standard telecom-grade laser sources. The integrated control hardware and computer application embedded in each TeraTone module guarantee turn-key and 24/7 unsupervised operation.

Outperforms typical coherent sources
