The combination of this format with pulse modulation (CSRZ), developed by NTT, enhances the sensitivity, and enables dense WDM long-distance transmission.
Modulation format in which CSRZ pulse modulation is added to differential quadrature phase modulation; it is appropriate for high-density WDM long-distance transmission.
59/66) belongs to CSRZ IIB (= [CSRP.sup.e]), see Duensing 1906, 7; for its complete reading and correct placing within the manuscripts see Muller-Kessler and Sokoloff 1998a, 66-67, 202.
