Abstract: Signal processing sections selectively switch modulation/demodulation in low-efficiency modulation system and modulation/demodulation in high-efficiency modulation system, and perform digital signal processing. Parallel-side interfaces of input/output interface sections are electrically connected to the signal processing section. A serial-side interface of the input/output interface section is electrically connected to a serial-side interface of the input/output interface section. A selection section electrically connects a parallel-side interface of the input/output interface section to the signal processing section when the low-efficiency modulation system is selected, and electrically connects the parallel-side interface of the input/output interface section to a parallel-side interface of the input/output interface section when the high-efficiency modulation system is selected.

Abstract: A processing equipment includes a processing unit having a plurality of functions. A retaining unit retains a device identifier capable of identifying the processing equipment. An interface unit receives a function authentication key which is a code for setting a specific function among the plurality of functions to be enabled or disabled. A control unit sets the specific function to be enabled or disabled according to the function authentication key when a device identifier included in the received function authentication key coincides with the device identifier retained in the retaining unit.

Abstract: A parallel transfer rate converter inputs first parallel data with number of samples being S1 pieces in synchronism with a first clock, and outputs second parallel data with number of samples being S2=S1×(m/p) pieces (p is an integer equal to or larger than 1) in synchronism with a second clock having a frequency which is p/m times of a frequency of the first clock. A convolution operation device inputs the second parallel data in synchronism with the second clock, generates third parallel data with number of samples being S3=S2×(n/m) pieces (S3 is an integer equal to or larger than 1) by executing a convolution operation with a coefficient indicating a transmission characteristic to the second parallel data, and outputs the third parallel data in synchronism with the second clock.

Abstract: It is an object to provide a technique capable of using a single framer as a necessary framer and causing the framer to be shared among a plurality of transmission destinations and priorities when coping with a plurality of transmission destinations or priorities and a change in a bandwidth of a physical lane that is caused by a change in a modulation scheme or a change in the number of wavelengths.A multilane transmission device that allocates client signals based on a transmission destination or a priority, decides the number of virtual lanes necessary for transmission of the client signals allocated based on each transmission destination or each priority, allocates the client signals allocated based on each transmission destination or each priority to the virtual lanes whose number has been decided, and frames the client signals allocated to the virtual lanes as transport frames, multiplexes the virtual lanes into a physical lane, and transmits the framed transport frames by using the physical lane.
