Description
Technical field
The present invention relates to EPON field, more particularly to a kind of optical network unit powered device based on POE mode.
Background technology
For present EPON, power supply is a very important link, at present, two kinds is typically used in optical network unit power supply mode, first, being equipped with a power supply adaptor to each optical network unit to complete the power supply to optical network unit；Second, being powered from civil power in user family or other battery powers to optical network unit.Shortcoming using this kind of power supply mode is that the cost of optical network unit includes the cost of power module, so that cost is of a relatively high；Requirement to power supply facilities is high, must have preferable power supply facilities in the place using optical network unit；The stability of optical network unit is limited by power supply module, if power module is damaged, optical network unit can be caused can not to use or destroy optical network unit；And power supply distance is extremely limited.
The content of the invention
It is an object of the invention to overcome disadvantages mentioned above to be powered there is provided one kind by Ethernet to optical network unit, the stability of device of optical network unit is improved, the optical network unit powered device based on POE mode of optical network unit cost is reduced.
Optical network unit powered device of the invention based on POE mode, its circuit is constituted by separation voltage and data-signal circuit and by electro-detection and voltage conversion circuit, its input/output relation is, separation voltage and the input of data-signal circuit connect Ethernet socket, it, which is exported, receives electro-detection and voltage conversion circuit input, and optical network unit is connect by electro-detection and voltage conversion circuit output.Wherein, separation voltage and data-signal circuit are by Ethernet-port U5And U6, magnetic separator U4, bridge rectifier D15And D16, resistance R1、R2、R6And R7, electric capacity C1、C2、C10、C112And C16Constitute；By electro-detection and voltage conversion circuit by power control and voltage changer U1, optical coupling isolator U2, reference voltage comparator U3, high-power switchgear pipe Q1, transformer T1, inductance L1, voltage-regulator diode D8And D14, diode D3And D6, electric capacity C3~C7、C9、C12~C15、C17、C20、C22、C23、C25And C28, resistance R8、R10、R14~R17、R22~R28And R127Constitute.
The optical network unit powered device based on POE mode of the invention is arranged on device of optical network unit when using, and its course of work is, and one) connection cable：By on present apparatus access network based on ethernet socket；Two) detect：The device is detected to the voltage that Ethernet is transmitted, whether 2.8V~10V is reached, such as detect after this voltage, the device is just determined resistance value by one and is placed on current supply circuit, electric current on loop will change with voltage, by detecting the electric current, power supply unit is known that Ethernet cable terminal has an effective optical network unit to need power supply；If the resistance value of placement is in the range of 12K~23.7K or 26.25K~45K, and power supply unit then thinks the optical network unit effectively, but is not required to power supply, such as resistance in other scopes, it is meant that invalid optical network unit detection, it is impossible to power；Three) classify：Complete after detection, the voltage on network link is increased to 15.5V~20.5V by power supply unit, optical network unit produces fixed voltage using internal regulator, thus obtains a fixed current, so as to realize that optical network unit is classified；Four) power supply is started：When optical network unit is connected and obtains power supply from Ethernet, power over Ethernet device is powered since low-voltage to device of optical network unit, until providing 48VDC dc source；Five) by electricity：When the voltage that device of optical network unit is received by Ethernet is higher than 48VDC, power supply unit starts to be powered optical network unit.
The advantage of the optical network unit powered device based on POE mode of the invention is, the construction cost of EPON can be greatly lowered, the safety and stability that optical network unit is powered is improved, has very important effect for the construction for promoting EPON.
