PDH is the best solution for synchronization(timing) network
PDH is replaced by SDH, which is not good enough for timing signal
transport.
DWDM should take the responsibility for timing transport

Benefits: Transport 3 timing signals simultaneously with 1+1 protection
Transport timing by PDH in OSC, droppable at any nodes
Timing signal and traffic are separated for easier maintenance

DWDM Solution for G.653 Fiber (DSF)DWDM Solution for G.653 Fiber (DSF)
G.653 fiber is dispersion-shifted fiber (DSF)
With zero dispersion at the point of 1550nm, normally perfectly
supports the transmission of single channel up to 10G signals
When used for DWDM system, it easily leads to FWM (Four-wave
Mixing) and other nonlinearity effects which greatly degrade the
system performance.
Confidential, Huawei Copyrighted 20
SuperWDM technology is better than NRZ technology in the
tolerance of FWM.
Using SuperWDM together with FEC, the input power can be much
higher, and the optical signal can reach up to 500km without electrical
regenerator.
Wavelength spacing is not even as for NDSF fiber. 8-wavelength
or 12-wavelength transmission supported
