Problems solved by technology

[0004] In view of this, the embodiments of the present invention provide a data processing method, device, and system in an optical network system, which are used to solve the problem that the encoding method of the existing optical network system causes a large system overhead and cannot detect lines. Under the condition that the line rate remains unchanged, a new encoding method is adopted to reduce the system overhead and realize line detection at the same time, which is simple to implement and greatly improves the performance of the system

Abstract

The present invention provides a data processing method in an optical network system, apparatus and system, by the 8-bit / 10-bit decoded data stream 32 bits to 34 bits of encoding and the 32 bits to 34 bits of encoded data stream forward error correction encoding, and the data stream after the encoding is sent out; Or the received data stream for forward error correction decoding, as well as the forward error correction decoding after the data stream 32 bits to 34 bits of decoding, to achieve a new coding method, saving the bandwidth resources of the line, while without interrupting the service can be realized on the line monitoring, to achieve simplicity, greatly improving the performance of the system.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a data processing method, device and system in an optical network system. Background technique [0002] Passive Optical Network (PON) technology is currently one of the most widely used Fiber To The Home (FTTH) technologies. Existing PONs can be classified into power-division passive optical networks and wavelength division multiplexing passive optical networks (wavelength division multiplexing Passive Optical Network, WDMPON) according to signal distribution methods. The current Broadband Passive Optical Network (BPON), Gigabit-capable Passive Optical Network (GPON) and Ethernet Passive Optical Network (EPON) belong to power division type passive optical network. WDMPON based on wavelength division multiplexing technology uses wavelength division multiplexing technology to realize uplink access, which can provide higher working bandwidth and realize symmetrical broadban...
