摘要： The present invention provides a signal block sequence processing method enabling a standardized existing system to be utilized even with a difference in interface speed between LAN and WAN. According to the method, signal block headers (Bch, Bdh) are deleted from each sequence of signal blocks (B) each composed of the signal block header (Bch, Bdh) indicating whether a signal block payload is a control block payload (Bc') in which a control code is contained or a data block payload (Bd') in which data is contained. The resultant signal blocks are formed into one group (G). Each control block payload in the group is provided with position determination information indicating the position of the control block payload in the group. The signal block payloads are rearranged in accordance with a signal block payload rearrangement rule predetermined to a receiving side. The rearranged signal block payloads are contained in a super-block payload. A super-block header (Shc) indicative of containment of control block payloads is added to the super-block payload (Sc). The resultant super-block (S) is output.

摘要： A dual structure for a multiplexing section extended to an OSU is obtained without adding a dynamic function, such as an optical switch, to a W-MULDEM. The W-MULDEM of an optical wavelength division multiplexing access system divides, among ports corresponding to the individual ONUs, downstream optical signals having wavelengths λd1 to λdn, which are received along a current-use optical fiber, or downstream optical signals having wavelengths λd1+Δλ to λdn+Δλ, which are received along a redundant optical fiber. The W-MULDEM also multiplexes, for the port that corresponds to the current-use optical fiber or the redundant optical fiber, upstream optical signals having wavelengths λu1 to λun or wavelengths λu1+Δλ to λun+Δλ, which are received along optical fibers corresponding to the ONUs. A wavelength difference between the downstream optical signal and the upstream optical signal that are consonant with each ONU is defined as an integer times the FSR of an AWG.
