Abstract

The application provides an optical assembly and an optical line terminal. The optical assembly is composed of a transmitting unit, a wavelength division multiplexing device, a first receiver, a second receiver, a lens element and an optical fiber interface. The transmitting unit is configured to transmit light including a first wavelength and a second wavelength. The lens element is configured to couple the light including the first wavelength and the second wavelength to the optical fiber interface and carry out beam transformation on uplink signals of a third wavelength and a fourth wavelength. Compatibility of a GPON and an NG-PON as well as compatibility of two kinds of corresponding ONUs in a network is realized; and thus smooth upgrading of the GPON system to the NG-PON system is realized.

Description

technical field [0001] The present application relates to the field of optical fiber communication, in particular to an optical component and an optical line terminal. Background technique [0002] The improvement of the transmission rate of the access network needs to upgrade the Gigabit-Capable Passive Optical Network (GPON) network to the next-generation passive optical network (Next Generation PON, NG-PON), because they use different transmission Wavelength, during the transition period of system upgrade, both GPON and NG-PON exist in the access network structure. The current solution is to add optical wavelength multiplexing and demultiplexing equipment to the optical link, which increases the complexity of the system and is not conducive to the smooth upgrade of the overall system. [0003] At present, the upgrade from GPON to NG-PON can adopt the external multiplexer solution. This solution needs to add supporting equipment such as NG-PON line cards, external multip...
