Problems solved by technology

However, because the optical components with wavelength selection function are quite expensive, they are not suitable for use in ONU optical modules at the user end, so they cannot be widely promoted and applied.
Second, to assign a fixed wavelength to each ONU optical module, it is necessary to select an optical module with a specific receiving wavelength for each ONU at the user end. How many ONUs there are,

Example Embodiment

[0032] The technical solution of the present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0033] Please refer to figure 1 , The figure shows a functional block diagram of an embodiment of the optical module of the present invention.

[0034] This embodiment takes the ONU optical module at the optical network unit side as an example, such as figure 1 As shown, the optical module includes a light emitting component 11 and a light receiving component 12, wherein the light emitting component 11 is integrated with a temperature controller. Among them, the temperature controller can and is preferably implemented by a semiconductor refrigerator.

[0035] The light emitting component 11 is connected to the transmitter control circuit 14. The transmitter control circuit 14 provides burst mode driving current and modulation current for the light emitting component 11, and is controlled by the burst enable signal input by the m...

Abstract

The invention discloses an optical module and a passive optical network with the same. The optical module comprises a master control unit, an optical emitting component integrate with a temperature controller, a temperature controller driving unit and a wavelength tuning unit. By the wavelength tuning unit and the temperature controller driving unit in the optical module, the emitting wavelength of the optical module can be conveniently adjusted by the master control unit of the optical module, wavelength adjustment manner is simple, and difficulty and cost for building the network by optical modules are reduced.

Description

technical field [0001] The invention relates to the technical field of optical communication, in particular to a wavelength tunable optical module and a passive optical network with the optical module. Background technique [0002] Passive Optical Network (PON) is a point-to-multipoint optical fiber transmission and access technology, which originated in the mid-1990s. With the evolution of PON technology, broadband passive optical network (BPON), Ethernet passive Optical Network (EPON) and Gigabit Passive Optical Network (GPON) and other technologies. Passive optical network has developed rapidly because of its broadband, service integration, flexible networking capabilities, and low cost. At present, the commonly used passive optical networks are EPON and GPON. [0003] For EPON and GPON technologies, most of them adopt time-division multiple access (TDM) technology at present, which cannot well meet the rapidly increasing demands of users' bandwidth. Moreover, since the...
