Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to an optical communication module and an optical add / drop device applied to an optical communication device.
[0002]
[Prior art]
In recent years, with an increase in traffic, an increase in network capacity has been required. In order to satisfy the demand, research and development of optical communication devices and optical communication modules for optical communication devices have been actively conducted.
[0003]
FIG. 44 is a block diagram of a general optical communication module called an optical transceiver (see Non-Patent Document 1). In FIG. 44, 01 is a photoelectric converter, 02 is a signal reproducing circuit, and 03 is an electro-optical converter. Such a module has high versatility, but when configuring a communication device that processes a large number of optical signals, it is necessary to mount a large number of optical communication modules, and it is difficult to reduce the size of the communication device. Further, when the data rate of the optical signal is increased, there is a problem that wiring of the electric signal becomes difficult.
[0004]
FIG. 45 shows an optical communication module in which signal format conversion circuits 04 and 05 such as serial-parallel conversion are added to the optical communication module of FIG. 44 (see Non-Patent Document 2). After converting the input optical signal into an electric signal, the signal format conversion circuit 04 performs serial-to-parallel conversion and outputs it as a parallel electric signal. Also, after inputting the parallel electric signal and performing parallel-serial conversion with the signal format conversion circuit 05, By converting the signal into an optical signal, it is possible to solve the problem of the electric signal wiring, which is one of the problems of the optical communication module in FIG. However, it is difficult to reduce the size of a communication device that processes a large number of optical signals.
[0005]
As an optical communication module for realizing miniaturization of a communication device that processes a large number of optical signals, research and development of an optical communication module in which a plurality of functional blocks mounted on the optical communication module in FIG. Is underway. Examples of specifications of such an optical communication module include a parallel electric signal interface corresponding to four sets of optical signal inputs / outputs called SFI-5s by Optical Internetworking Forum (OIF), which is a consulting body of industry standard specifications for optical communication. (See Non-Patent Document 3). FIG. 46 is a block diagram of an optical communication module to which the standard is applied. In FIG. 46, reference numeral 011 denotes four photoelectric converters, 012 denotes four signal reproducing circuits, 013 denotes four electro-optical converters, 014 denotes four signal format converters, and 015 denotes four signals. It is a format conversion circuit.
[0006]
On the other hand, when the data rate of the optical signal is high, not only the problem of wiring of the electrical signal but also the performance required for the electro-optical converter and the opto-electric There is a problem that it is difficult to reduce the cost of a device or the like, and research and development of an optical communication module for processing an optical signal input / output as a parallel optical signal as an optical communication module for solving the problem are being advanced. As a specification example of such an optical communication module, an optical communication module standard called VSR4-01 has been created in OIF. FIG. 47 is a block diagram thereof (see Non-Patent Document 4). In FIG. 47, reference numeral 021 denotes a plurality of photoelectric converters, 022 denotes a plurality of signal reproducing circuits, 023 denotes a plurality of electro-optical converters, 024 denotes a plurality of signal format converters, and 025 denotes a plurality of signal format converters. .
[0007]
In such an optical communication module, a plurality of opto-electric converters and the like are mounted. However, since signals input from the plurality of opto-electric converters are collectively processed, as shown in FIG. Cannot be processed independently. Therefore, it is difficult to reduce the size of a communication device that processes a large number of optical signals.
[0008]
FIG. 48 is a block diagram of an optical communication module called a 4-channel CWDM type among standards of an optical communication module called VSR-5 in the OIF (see Non-Patent Document 5). In FIG. 48, 031 denotes four photoelectric converters, 032 denotes four signal reproducing circuits, 033 denotes four electro-optical converters, 034 denotes a signal format converter, 035 denotes a signal format converter, and 036 denotes a signal format converter. A WDM splitter 037 is a WDM multiplexer.
[0009]
Since this optical communication module also processes signals input from a plurality of photoelectric converters collectively as in the optical communication module of FIG. 47, it is not possible to independently process a plurality of optical signals as shown in FIG. Absent. Therefore, it is difficult to reduce the size of a communication device that processes a large number of optical signals.
[0010]
As described above, an optical communication module similar to the optical communication module shown in FIG. 46 is considered to be optimal for realizing miniaturization of a communication device that processes a large number of optical signals. Block diagrams of the device when the communication module is applied to an optical add / drop device are as shown in FIGS.
[0011]
FIG. 49 is a block diagram of a device in a case where an optical communication module similar to the optical communication module of FIG. 46 is applied to a general optical add / drop device using an optical switch (see Patent Document 1). 49, reference numeral 041 denotes an optical communication module, reference numerals 042 to 046 denote optical switches, reference numeral 047 denotes a WDM multiplexer, reference numeral 048 denotes a WDM demultiplexer, L is the number of wavelengths, and M is L or less.
[0012]
FIG. 50 is a block diagram of an optical add / drop device when the optical switch of FIG. 49 is changed to a switch for inputting and outputting an electric signal. In FIG. 50, 051 is an optical communication module, 052 to 056 are electric switches, 057 is a WDM multiplexer, 058 is a WDM demultiplexer, L is the number of wavelengths, and M is L or less.
[0013]
FIG. 51 is a block diagram of an optical add / drop device when the electric switches 052 to 056 of FIG. 50 are integrated into one electric switch 059. Note that L is the number of wavelengths, M is less than L, the input is L + M, and the output is L + M.
[0014]
In either case, an optical switch or an electric signal input / output switch is required, and it is desired to reduce the number of components in order to reduce the size and cost of the device.
