Embodiment Construction

[0018] combine figure 1 , figure 2 The device of the technical solution of the present invention is further described: the central processing unit circuit comprises a central processing unit (CPU), a slice of EEPROM, a slice of flash memory (FLASH), and two slices of static random access memory (SRAM); wherein the CPU For command processing, EEPROM stores board and module information, such as service rate type, etc., FLASH stores board program, and SRAM provides data space for program operation;

[0019] The FPGA circuit includes a piece of FPGA, and the logic inside the FPGA is as figure 2 As shown, it includes a bus input and output latch (LPM-DEF), two NOR gates (NOR2), a bus input and output tri-state gate (TRI) and an AND gate (WIRE). When the rate is set, the latch is first cleared by the clear signal ( / clr). When the rate is set, the CPU opens the latch by setting the rate address ( / setrate) and the write command ( / wr), and the data line (d[ 1..0]) is output to the...

Abstract

The present invention relates to a method of flexible configuration of rate of optical wavelength converter and its equipment, and relates to service rate conviguration of optical wavelength converter in clense wave division multiplexing system. It includes single board portion and optical transceiving module, in which the single board portion includes CPU circuit, AD and DA circuits, EPGA circuit and SDH overhead processing circuit, and the function of single board portion includes: collecting the performance index of input and outupt light of optical transceiving module, up-reporting the monitored performance index to network management system, at the same time receiving and processing command given out by network management system.

Description

technical field [0001] The invention relates to the technical field of all-optical communication network, in particular to the problem of service rate configuration of an optical wavelength converter in a dense wavelength division multiplexing system. Background technique [0002] In the DWDM system, the main function of the optical wavelength converter is to use the optical / electrical / optical conversion method to convert the SDH signal of any manufacturer that meets the requirements of G.957 recommendations into optical signals that meet the requirements of G.692, that is The optical signal from the SDH optical terminal is converted into an electrical signal through the optical wavelength converter transceiver module, and then the electrical signal is converted into an optical signal that meets the requirements of G.692 through the optical wavelength converter transceiver module, and the relevant monitoring information of the transceiver module is reported to the network man...
