Problems solved by technology

At the initial application stage of WDM equipment, the monitoring information that needs to be transmitted in the system is not very rich, and the signal bandwidth of 2M can still meet the transmission requirements. The original 2M optical monitoring and transmission system gradually showed its insufficient bandwidth

Embodiment Construction

[0019] The technical principles and specific embodiments of the present invention will be explained in detail below in conjunction with the accompanying drawings.

[0020] Such as figure 1 and 2 As shown, in order to realize the purpose of expanding the monitoring information transmission bandwidth, the optical monitoring information transmission system of the present invention has a network element management overhead byte (DCCR) at the original rate of 512Kbit / s, and a rate of 512Kbit / s multiplex section network management byte (DCCM) and business disk (EOW) 64Kbit / s rate regenerator section business byte (E1), 64Kbit / s rate multiplex section business byte (E2), 64Kbit / s rate user byte (F1 ) on the basis of adding two 2M port signals, such as figure 1 and 2 Indicated by the first 2M signal and the second 2M signal, the two 2M signals can meet the external clock requirements or be used as a simple 2M service channel. The present invention has increased the 485 interface d...

Abstract

The invention relates to an optical monitoring information transmission method and optical monitoring information transmission system used thereby, wherein optical signal having 1510 nanometer of wavelength separate from main light channels is utilized to transmit monitoring information with transmission band being 25Mbit / s, as the result of the increase of transmission system effective bandwidth, some appended business channels can be transmitted to meet the demand of network building.

Description

technical field [0001] The present invention relates to an optical monitoring information transmission method and an optical monitoring information transmission system used in the method. More specifically, the present invention relates to a method of transmitting at 25Mbit / s using a 1510nm wavelength signal independent of the wavelength of the main optical channel. A method for transmitting network management, business and other networking information in a wavelength division multiplexing system at a rate and an optical monitoring information transmission system used in the method. Background technique [0002] In the existing wavelength division multiplexing transmission system, the optical monitoring channel with a transmission bandwidth of 2.048Mbit / s is usually used, and the central wavelength of 1510nm specified in the national communication industry standard optical wavelength division multiplexing system requirements is used, and the CMI line is used The code type pr...
