Abstract :
We discuss our work on two-color one-way frequency transfer over optical fiber. We have expanded on our previous work by extending the wavelength separation by using one channel in the C band at 1553nm and the other channel in the O band at 1310nm. Both wavelengths have low loss and are well suited to use in optical fiber networks. We present measurements of the improved two-color phase delay as a function of temperature and compare that to the actual phase delay brought about by temperature induced length changes in the link. We also show improved closed loop performance of the link, including the dependence on the total length of the link.
