Abstract: PROBLEM TO BE SOLVED: To provide an optical transmission system in which crosstalk is reduced. SOLUTION: A semiconductor amplifier is used to impose modulation on an optical carrier signal having the same wavelength or a differently polarized optical carrier signal with data and a complement to the data. Modulated signals are combined. The modulated signals have nearly constant amplitudes, polarized signals are reproduced, and one or both of the signals are demodulated, so that the original signal is reproduced at a reception end.

Abstract: PROBLEM TO BE SOLVED: To provide an optical communication network architecture that improves a system loss characteristic by effectively utilizing a primary network having a multi-band module and a sub network having the multi-band module or a single wavelength A/D module. SOLUTION: A practical embodiment includes an improved architecture of the optical communication system employing a wavelength division multiplex(WDM) technology or other multiplex technology. The system architecture includes a network consisting of primary nodes (12) interconnected by a proper optical transmission medium (14) and of sub networks comprising secondary nodes (S) connected to the various primary nodes interconnected by proper optical transmission media. At least one of the primary nodes has the multi-band module (M), and the sub networks are connected to at least one of the primary nodes having the multi-band module where at least one of the secondary nodes in the sub networks includes the multi-band module or the single wavelength A/D module.

Abstract: PROBLEM TO BE SOLVED: To provide an optical transmission system that adopts a signal mode fiber system to avoid interference between a wavelength division multiplex WDM signal and an analog television TV signal. SOLUTION: This wavelength division multiplex system has a 1st multiplexer 112 that connects a plurality of digital information channels to a transmission path and the transmission path including an optical fiber 130 whose zero dispersion wavelength λ0 is 1310 nm and whose length exceeds a span to 10 km. The loss of the optical fiber at 1385 nm is smaller than the loss at 1310 nm, and color element dispersion at a 1.4 μm wavelength band is within a range of 1.5-8.0 ps/nm.km, and the 1st multiplexer 112 gives three or more channels of wavelength division multiplex signals within the 1.4 μm wavelength band to the transmission path.

Abstract: A high-capacity optical fiber network Ä100, 200Ü includes wavelength-division multiplexing (WDM) within the 1.4 micron ( mu m) wavelength region (i.e., 1335-1435 nm). Such a system includes optical fiber Ä130Ü whose peak loss in the 1.4 mu m region is less than its loss at 1310 nm. The optical fiber has a zero dispersion wavelength ( lambda 0) at about 1310 nm, and linear dispersion between about 1.5 and 8.0 ps/nm-km within the 1.4 mu m region. At least three WDM channels operate at 10 Gb/s in the 1.4 mu m wavelength region and have a channel separation of 100 GHz. In one illustrative embodiment of the invention, a broadcast television channel, having amplitude modulated vestigial sideband modulation, simultaneously operates in the 1.3 mu m region (i.e., 1285-1335 nm) and/or the 1.55 mu m region (i.e., 1500-1600 nm). In another embodiment of the invention, 16 digital data channels are multiplexed together in the 1.55 mu m region, each channel operating at about 2.5 Gb/s. Raman amplifiers Ä103, 113Ü are used for amplification in the 1.3 mu m and the 1.4 mu m wavelength regions, whereas an Erbium amplifier Ä123Ü is used for amplification in the 1.55 mu m wavelength region.

Abstract: Semi-conductor amplifiers may be used in an optical transmission system without infecting transmitted data with cross-talk from adjacent channels by modulating the data and an alternative expression thereof onto respective optical carriers having the same wavelength, but polarized differently, and then combining the modulated signals. The modulated result is a signal having a relatively constant amplitude, but nevertheless carryin g the underlying data, which may be recovered at a receiving end by regenerating the polarized signals and demodulating one or both of those signals.
