Problems solved by technology

[0004] However, in the 10G EPON of the prior art, the uplink adopts the TDMA method for data transmission, that is, only one ONU performs uplink transmission at the same time, so that the bandwidth of the uplink channel is severely restricted by the EPON ONU and the asymmetric 10G EPON ONU, and the high bandwidth of 10G cannot be realized. transmission

Abstract

The embodiment of the invention provides a 10G Ethernet passive optical network (EPON) uplink transmission method, 10G EPON uplink transmission equipment and a 10G EPON uplink transmission system. The method comprises the following steps of: receiving a first uplink optical signal and a second uplink optical signal transmitted by a wavelength division multiplexer (WDM), wherein the first uplink optical signal and the second uplink optical signal are provided by a first optical network unit for supporting a first uplink rate and a second optical network unit for supporting a second uplink rate respectively, and the first optical network unit and the second optical network unit correspond to different wavelengths respectively; performing wavelength detection on the second optical signal to judge whether the second optical network unit and the first optical network unit have wavelength conflict; and if the wavelength conflict is detected, inhibiting the second optical network unit to send uplink optical signals. According to the embodiment, uplink transmission is performed in the 10G EPON through the WDM so as to realize 10G high bandwidth transmission.

Description

technical field [0001] Embodiments of the present invention relate to the communication field, and in particular, to a 10G EPON uplink transmission method, device and system. Background technique [0002] In the Gigabit Ethernet Passive Optical Network (hereinafter referred to as: EPON), the optical line terminal (Optical Line Termination; hereinafter referred to as: OLT) located at the central office and the optical network unit (Optical Network Unit) located at the user end; Hereinafter referred to as: ONU) adopts a point-to-multipoint data transmission mode, and the uplink and downlink rate is 1.25G. Among them, the downlink transmission wavelength is 1490nm, adopting the broadcast mode, and the uplink transmission wavelength is 1310nm, adopting the Time Division Multiple Access (TDMA) mode, and multiple ONUs share the uplink channel. The OLT realizes registration and online of the ONU and allocates uplink bandwidth for the ONU through a multi-point control protocol (Mul...
