Problems solved by technology

Existing EPON (Ethernet Passive Optical Network, Ethernet Passive Optical Network), GPON (Gigabit-Capable Passive Optical Network, Gigabit-Capable Passive Optical Network, Gigabit-Capable Optical Network, Gigabit Passive Optical Network) systems can only carry fixed network signals and cannot transmit mobile services
In the existing WDM-PON, each ONU (Optical Network Unit, optical network unit) uses a pair of uplink and downlink wavelengths, and the business carried is relatively simple. Either it can only carry fixed network signals, or it can only carry digital wireless signals. mobile signal
At present, the digital mobile repeater is generally added with an optical fiber relay antenna to transmit mobile services, but it can only carry digital wireless mobile signals similar to CPRI (Common Public Radio Interface, Common Public Radio Interface) frames
Due to limited optical fiber resources, it is often difficult to find available optical fiber cables in practical applications
[0003] With the continuous development of communication services, people's demand for integrated transmission of mobile services and fixed network services is becoming more and more obvious. However, traditional indoor mobile services generally have defects such as insufficient deep coverage, and the existing optical access system cannot meet the simultaneous requirements. Delivering market demand for mobile and fixed-line services

Abstract

The invention discloses a system and method for mobile and fixed comprehensive connection based on a WDM-PON and relates to the field of PON connection. The system for mobile and fixed comprehensive connection comprises a mobile and fixed comprehensive connection OLT, an ODN and a plurality of mobile and fixed comprehensive connection ONUs. The mobile and fixed comprehensive connection OLT is connected with the mobile and fixed comprehensive connection ONUs through the ODN. The mobile and fixed comprehensive connection OLT comprises a local side power distribution frame combining module, N side-by-side local side WDM-PON optical modules and a coupler, wherein N is a positive integer, and an inequation 8<=N<=64 is satisfied. The local side power distribution frame combining module is connected with the coupler through the N side-by-side local side WDM-PON optical modules. Each mobile and fixed comprehensive connection ONU comprises a far side frame combining module and a far side WDM-PON optical module. The coupler is connected with each far side WDM-PON optical module through the ODN. The system for mobile and fixed comprehensive connection based on the WDM-PON can transmit mobile services and fixed network services simultaneously, the deep covering of mobile wireless signals of an operator can be achieved, and main optical fiber resources for network connection can be saved.

Description

technical field [0001] The present invention relates to the field of PON (Passive Optical Network, Passive Optical Network) access, in particular to a mobile and fixed integrated access based on WDM-PON (Wavelength Division Multiplexing Passive Optical Network, Wavelength Division Multiplexing Passive Optical Network) systems and methods. Background technique [0002] As an important part of the optical fiber communication network, the PON access network has broad application prospects. Existing EPON (Ethernet Passive Optical Network, Ethernet Passive Optical Network) and GPON (Gigabit-Capable Passive Optical Network, Gigabit-Capable Passive Optical Network) systems can only carry fixed network signals and cannot transmit mobile services. In the existing WDM-PON, each ONU (Optical Network Unit, optical network unit) uses a pair of uplink and downlink wavelengths, and the business carried is relatively simple. Either it can only carry fixed network signals, or it can only ca...
