Abstract

The invention relates to a wavelength-adjustable receiver optical subassembly (ROSA) based on time and wavelength division multiplexing. The ROSA comprises a housing 1, a tunable filter plate 6, a film heating resistor 5 and a photodiode 3. The film heating resistor 5 is bonded above the tunable filter plate 6; an internal pin or lead wire 10 is welded on the film heating resistor 5; the lower part of the housing 1 and the photodiode 3 are fixed and assembled by glue; a side surface of the housing 1 has a hole or a circuit cover plate 2; internal pin or lead wire 10 welded on the film heating resistor 5 is connected with the hole on the side surface of the housing 1 or the circuit cover plate 2; the housing 1 and the circuit cover plate 2 are used to package the tunable filter plate 6, the film heating resistor 5, and the photodiode 3. The film heating resistor 5 is used to adjust a refractive index of the filter plate 6; the size can be minimized; the filter plate can be plastered easily; the device can be integrated, modularized, and minimized; the side surface of the whole housing has an electrical lead wire that is lead out; a welding wire won't fall off easily; and the packaging effect is good.

Description

technical field [0001] The invention belongs to the technical field of optical communication, and in particular relates to a wavelength-tunable optical receiving sub-module based on time division and wavelength division multiplexing. Background technique [0002] Based on time division and wavelength division multiplexing (TWDM-PON) is the technology choice of the communication industry in the next generation of optical fiber access (NG-PON2), TWDM-PON is determined by FANS as the main standard. TWDM-PON is a 10Gb / s TDM PON that stacks multiple wavelength channels, and requires at least 4 wavelengths to be supported. [0003] The tunable optical receiving device (Tunable ROSA) for TWDM-PON is an optical communication device that adapts to the NG-PON2 market and technology trends. This device is mainly used in the transceiver component optical network unit ONU in the passive optical network PON system Or the receiving part in the optical network terminal ONT. [0004] Tunab...
