Description

A kind of remote power feeding system and far end supply

Technical field

The invention belongs to Remote Power Supply technical field, relate in particular to a kind of remote power feeding system and far end supply.

Background technology

Along with the development of light access (Fiber To The x, FTTx), with optical fiber, replace the light entering and copper back strategy of copper cable to become in the world a kind of trend, it provides high bandwidth to access by shortening the distance of copper cable between local side apparatus and user.Under light entering and copper back strategy, such as the more and more close user of the trend that lays of the broadband access equipments such as digital subscriber line access multiplex (Digital Subscriber Line Access Multiplexer, DSLAM).This kind lays mode when promoting line bandwidth, also make broadband access equipment produce some new features, comprise broadband access equipment miniaturization, quantity is many, distribution is wide, it is complicated that scene is installed, these features become increasingly complex the power taking scene of broadband access equipment, even become the critical bottleneck that broadband access equipment is disposed.

Usually, adopt remote power feeding system to solve the problem of broadband access equipment power taking difficulty under light entering and copper back strategy.This remote power feeding system is utilized the idle copper cable twisted-pair feeder occurring in light entering and copper back process, realizes the remote transmission-receiving function of electric energy, as Fig. 1 shows the framework of the remote power feeding system that prior art provides.Local supply is modulated to export-48V direct current of machine room after the high voltage direct current of the isolation that suspends over the ground, through copper cable twisted-pair feeder, high voltage direct current remote conveying is delivered to far end supply; Far end supply carries out after protective separation and step-down this high voltage direct current, for corresponding load equipment.

The remote power feeding system that IEC60950-21 standard provides prior art has defined two kinds of standard systems: RFT-C standard and RFT-V standard.Wherein, RFT-V standard is mainly used in north America region, and its voltage is limited, and electric current can be larger; RFT-C standard is mainly used in European Region, its current limited, voltage can be higher, before power supply, can start local supply communicates by letter with the self check between far end supply, the self check communication protocol of different manufacturers is incompatible, for example, the local supply of BPS producer can not be realized and communicating by letter with the far end supply of Mitra producer.

Therefore, the remote power feeding system that prior art provides, when specific implementation, need to customize far end supply, and the far end supply of customization is integrated in an outdoor integrated equipment that is independent of load equipment, this integration apparatus is directly possessed far away from ability.Under this kind of customization mode, the far end supply of RFT-V standard has good versatility, is easy to customization, and the far end supply of RFT-C standard is because self check communication protocol is that producer is privately owned, for different manufacturers, need customize respectively the far end supply with different self check communication protocols, customization cost is high; And because far end supply need customize respectively according to the difference of manufacturer, make the complete machine configuration quantity of outdoor integrated equipment larger, be unfavorable for normalization and client's spare part of product.

Summary of the invention

The object of the present invention is to provide a kind of far end supply of remote power feeding system, the remote power feeding system that being intended to solve prior art provides is that the far end supply of customization is integrated in an outdoor integrated equipment, customization cost is high and make outdoor integrated equipment complete machine configuration quantity large, is unfavorable for the problem of product normalization and client's spare part.

The present invention is achieved in that a kind of far end supply of remote power feeding system, and described far end supply comprises:

Replaceable module, for realizing the function there are differences between each manufacturer's far end supply; And

One connects the public module of described replaceable module, for realizing other function the function that far end supply there are differences between described each manufacturer.

Another object of the present invention is to, a kind of remote power feeding system is also provided, comprise a local supply and the far end supply being electrically connected to described local supply, described far end supply is the far end supply of remote power feeding system as above.

The part that may there are differences between the far end supply Shi Jiangge manufacturer due to remote power feeding system provided by the invention is abstract is detachable and interchangeable replaceable module, it can or customize according to the difference of manufacturer according to the different of power supply system, and in conjunction withpublic module 12, jointly complete the function of far end supply, the relative prior art of customization cost is low, and public module can be integrated in load equipment or be independent of in the outdoor integrated equipment of load equipment, and the complete machine that can not increase equipment configures quantity, be convenient to management and client's spare part of product, be beneficial to popularization and the use of product.
