Abstract (in Japanese) (See Japanese page) 
(in English) In long-haul FDM optical fiber transmission systems, transmission characteristics are degraded by four-wave mixing (FWM) in optical fibers. To overcome this problem in equally-spaced (ES) allocations, modified repeated unequally-spaced (RUS) allocations such as equally-spaced RUS (ERUS) and unequally-spaced RUS (URUS) allocations have been already proposed as frequency allocations and examined.
FWM noises are also closely related to modulation formats such as non-return-to-zero (NRZ), random return-to-zero (RZ), differential phase-shift keying (DPSK), and bit-phase arranged RZ (BARZ), and it has been already found that FWM noises are lowest in URUS with BARZ.

In this paper, to reduce FWM noises further, quaternary BARZ (Q-BARZ) is proposed as a modulation format, and FWM noises are analyzed. It is found that FWM noises with channel frequencies vanish in RUS, ERUS, and URUS with Q-BARZ.
