Embodiment 1

[0039] The invention discloses a device for simultaneous communication with multiple optical modules applied to an optical network, which adopts circuit design and CPLD logic design to complete the writing of the register of one optical module, and only 30 I2C bus clocks are needed; When writing the same information to the same register address of 8 optical modules, only 30 I2C buses are needed.

[0040] Such as image 3 As shown, the device for simultaneous communication with multiple optical modules in this embodiment includes:

[0041] The CPU unit 110 is respectively connected to a plurality of the optical modules 120 through the serial data line 140 of the I2C bus;

[0042] The clock gating unit 130 is connected to the CPU unit through a high-speed parallel bus LocalBUS 160, and is respectively connected to a plurality of the optical modules 120 through the serial clock line 150 of the I2C bus; it is used to determine the number of the optical modules. Separate the clock signal...

Embodiment 2

[0067] Such as Figure 5 As shown, this embodiment discloses a method for simultaneous communication with multiple optical modules applied to an optical network, including:

[0068] Write operation to the optical module:

[0069] There are two types of write operations for optical modules by the CPU unit: one is to write different values ​​to the registers of the optical module, that is, to write to a single optical module; the other is to write the same register for different optical modules Write the same value to the address, that is, write multiple optical modules at the same time.

[0070] Gating the clock signal corresponding to the optical module:

[0071] According to the type of write operation of the CPU unit to the optical module, select the corresponding clock signal:

[0072] When the CPU unit needs to write to a single optical module, you can write “1” to the corresponding 1 bit clock gating register bit in the clock gating unit, and write “0” to the other 7 bit clock ga...

Abstract

The invention provides a device and a method for simultaneous communication with multiple optical modules, which are applied to an optical network. The device comprises a CPU (Central Processing Unit) unit and a clock gating unit, wherein the CPU unit is respectively connected to the optical modules through serial data lines of an I2C bus; the clock gating unit is connected to the CPU unit through a high-speed parallel bus, is respectively connected to the optical modules through serial clock lines of the I2C bus, and is used for separating a clock signal according to the number of the optical modules and completing gating of the clock signals of the optical modules, wherein each serial clock line of the I2C bus is pulled up to a power level through a pull-up resistor. Multiple bit clock gating register bits are arranged in the clock gating unit, and each bit clock gating register bit is corresponding to one optical module. The device and the method both support mass writing operation to the optical modules and independent read-write operation to the optical modules, the flexibility is strong and the system efficiency is greatly improved.

Description

Technical field [0001] The present invention relates to the field of optical network technology, and in particular to a device and method for simultaneous communication with multiple optical modules applied to an optical network. Background technique [0002] There are 8 optical modules on the 8-port GE (GigabitEthernet) uplink card in the optical network, and each optical module communicates with the CPU through the I2C (Inter-Integrated Circuit) bus interface. The optical module is a standard device, and the optical module is fixed and cannot be set; therefore, the address of each GE optical module installed on an 8-port GE uplink card is the same, that is, 8 optical modules have the same The CPU cannot directly communicate with 8 optical modules at the same time, and writing information of multiple optical modules at the same time will cause excessive CPU resource usage and low system efficiency. [0003] Such as figure 1 As shown, the optical module has two storage areas: the ...
