Abstract

The embodiment of the invention provides an optical module, relates to the technical field of communication, and aims at expanding network bandwidth, solving the problem of dynamic bandwidth distribution in the field of access network, reducing the production and use cost as well as increasing the quantity of users of an optical network terminal. The optical module comprises a light receiving and transmitting assembly and a control circuit, wherein the light receiving and transmitting assembly comprises a first laser and a second laser; the control circuit controls the first laser to generate a light sight at the first wave band, and the first laser is used for emitting the light signal at the first wave band to a transmission fiber; or the control circuit controls the second laser to generate the light signal at a second wave band, and the second laser is used for emitting the light signal at the second wave band to the transmission fiber. The optical module is applied to wave division multiplexing passive optical network.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to an optical module. Background technique [0002] In the current optical fiber communication system, especially in the field of access network, due to the continuous increase in the demand for services such as high-definition video and ultra-clear video, the Ethernet Passive Optical Network (EPON for short) currently used in the field of access network, The bandwidth provided by technologies such as Gigabit Passive Optical Network (GPON for short) can no longer meet the needs of customers. At the same time, due to many problems in EPON, GPON and other technologies, such as dynamic bandwidth allocation, it seriously affects the actual use effect of the existing Time Division Multiplexing-Passive Optical Network (TDM-PON) technology. The optical module on the network side provided in the prior art usually uses a single-emitting laser. Due to the limitation of the emission ba...
