Abstract

The present invention discloses a method, an apparatus, an optical component and an optical network system for controlling an operating temperature of an optical component. The method includes: acquiring an external ambient temperature of the optical component; setting a target control temperature of a temperature controller according to the external ambient temperature, where the target control temperature is a function value of the external ambient temperature, and the target control temperature is within a range from an operating temperature lower limit of a laser to an operating temperature upper limit of the laser; and controlling, according to the target control temperature, an operating temperature of the optical component by means of heating or cooling by using the temperature controller.

Description

technical field [0001] The invention relates to the field of optical networks, in particular to a method, a device, an optical component and an optical network system for controlling the working temperature of optical components in the field of optical networks. Background technique [0002] 10G passive optical network (referred to as "PON") includes 10G Ethernet passive optical network (10G bit / S Ethernet Passive Optical Network, referred to as "10G EPON") and 10G bit passive optical network (10G -Gigabit-capable Passive Optical Network, referred to as "XG PON"). The standard organization defines that an optical line terminal (Optical Line Terminal, “OLT” for short) of the 10G passive optical network adopts an optical signal with a wavelength of 1577nm and a wavelength range of 1575nm˜1580nm. In order to meet the above requirements, the laser of the 10G passive optical network needs to use an electric absorption modulated laser (Electricity Absorb Modulate Laser, “EML” for...
