Problems solved by technology

[0008] 1. Traditional PDH / SDH transmission equipment only provides PDH and SDH standard series rate interfaces, while IP services and image services must be converted by PDH and SDH interfaces before entering the SDH transmission channel, so there are many layers of conversion circuits and low efficiency. Signal distortion is prone to occur, and the equipment is expensive,
[0009] 2. Traditional SDH equipment is designed for circuit switching services. If asymmetric real-time services such as IP data and images are transmitted, bandwidth will inevitably be wasted
[0010] 3. Limited support for other major network technologies such as IPX
[0011] 4. There are many cross-ring circuits, the circuit configuration is difficult, and the network maintenance is inconvenient
Therefore, it is not an ideal solution to transmit IP in the PDH / SDH optical network system by adding the technical method of IP interface board

Abstract

The apparatus thereof comprises: PDH / SDH / ATM accessing optical path, device accessing and outputting optical path, light wavelength multiplexer and Ethernet data processing circuit. The invention uses the software to monitor the optical IP access interface and the Ethernet interface and to send the alarm. The invention uses light wavelength division multiplexing technology, and adopts the two-cores optical fiber originally used by PDH / SDH / ATM optical network as transmission carrier; based on the no-change of original PDH / SDH / ATM system, the 10 / 100 / 1000M or higher IP data transmission channel is embedded into the PDH / SDH / ATM system.

Description

1. Technical field: [0001] At present, there are huge PDH / SDH / ATM optical network systems that have invested a lot of money in our country and even in the world. How to solve the problem of IP data transmission on the existing PDH / SDH / ATM optical network is the current PDH / SDH / ATM optical network system. As an important problem faced by ATM optical network, the present invention provides a method for efficiently establishing an IP data transmission channel on an existing PDH / SDH / ATM optical network and a technology for implementing equipment. [0002] Use the 2-core optical fiber originally used in the PDH / SDH / ATM optical network system as the transmission carrier, and the IP data channel uses another optical wavelength different from PDH / SDH / ATM to work, without making any changes on the basis of the original network, completely retaining PDH / All the functions of SDH / ATM system, use the original two optical fibers of PDH / SDH / ATM network to embed 100 / 1000M or even higher rate...
