Introduction: This pieces of paper takes up the present by using Copper-optical EPON within this assumption of the initial using PHSOE know-how exchange with all the birdwatcher line PHS Business circle transformation connected with light to stop to help keep office assistant PHS system transmission caused by "light in the copper, very little withdrawal" awkward situations. Today's pattern is also essential reform about the PHS transmission circle it? Look at the Internet less than a very usual post: "Using that olt + onu about , an original PHS base stations, the way do? If you employ the built-in style IAD connected with ONU in order to resolve this problem, in that case It possessed access over the truck driver (ISDN) on the PHS trust stations, how do? If onu merely solve part of broadband, tone of voice also utilize primary copper, next that's the trend of lighting suitable copper refundable. Ha ha! hard, small Linktone multi-level just isn't 12 years returning is ofte n completed. professionally think, within a PHS light into your community can easily merely get back the actual copper. " 3G Telecommunications restructuring Mobile One-way fees, many of the essential complex and policy factors to the mountains with PHS company appears to the point wherever inadequate water complex, along with recent gossips of your considerable cut in your PHS people might seem that will verify the judge, however, PHS enterprise as well as end user In this come back to a sensible level nonetheless really should be kept immediately after a particular size compared to situated point out of little although nonetheless substantial, picture virtually 80 million PHS clients are capable of cutover once it? PHS starting channels to 1.6 million nationwide, reported scrapping the particular retirement? A large numbers of special user number will be we desire to turn they response it? Pregnancy since supplemental households every year, and after this studies is a very first 50 percent connected with pregnancy, just about 80% of adult females will change the particular original PHS mobile or portable phone, if the PHS cell telephone almost all straight into exactly what Communicate To satisfy what's needed of these Low-E? Therefore, that PHS business inside the subsequent 3-5 ages probably should not end up being instantly stopped, PHS could still run, nevertheless the confront associated with EPON FTTH technological innovation with the significant reconstruction, mostly constructed from PHS put faitth on stations with the twisted pair on the Board end with the tranny circle appears to be a new stumbling obstruct intended for FTTH, providers evaluations mild should the steam head back again on the office assistant insert are just about all digging will certainly found yourself in know an copper line in two dug, the cost is also high, consequently FTTH can become passing plenty of time to hand may also possibly be lighting PHS tranny circl e regarding Copper is needless to say necessary. What is definitely PHSOE? Why is PHSOE? PHSOE (PHS overEthernet), created for that Chengdu Si Dawei technique throughout the routine is admittedly against the subsequent floor which has a reliable Ethernet information vent connected with a U PHS technology, the use of this engineering might EPON, Fiber Transceiver , MSTP / MSAP optical community these kinds of because Ethernet in addition to reliable data transmission PHS U port. If so, the reason did most of us select PHSOE technology has become that easy in the PHS community connected with Copper's primary practical means? First: the expense of the particular PHS community alteration and also as much as doable without paying a smallish cost; Second: to use the prevailing sheets optical system devoid of occupying resources; again: to make because of its reconstruction is often a popular program to be able to a number of associated with coverage. We now review the standard PHS network tranny network and also platform inside the EPON circle right after change by using PHSOE the community diagram: Figure 1: Traditional PHS twisted pair transmission Figure 2: In this EPON technologies exchange stand through PHSOE PHS system transmission strategies Through the particular multi-level diagram for you to assess no matter whether we all satisfy this preceding conditions, 1, while the implementation of the FTTH EPON community without the need to make use of to develop the actual network, as well as dig out the particular substantial twisted set of two means can easily possibly be recycled for the similar time if your EPON community assembly should not duplicate the design or installation, thus greatly cutting down the cost; 2, and each of the mild on the pensionable course seriously isn't the same as copper, your technological know-how has become built simply Ethernet optical community platform without additional a fiber-optic; 3 , PHSOE have to have netw ork user interface will be Ethernet interface, plus the interface for many in the mild Network tools Provide wide-ranging protection plus easy construction. Based for the previously mentioned factors PHS network transformation preferred PHSOE technology. How? Circuit from the time really to be sure excellent transmission hesitate jitter allowing it to simply monitor timely PHS thoughts service, looking at that Ethernet technology is predicated on save in addition to forwards mechanism, a pair of mechanisms for acquiring this will determine its tricky to protect the tranny delay and clock extraction, and for that reason particularly tricky to realize the time. Our concrete floor implementation is definitely obtained employing SW1304F chip, the computer chip to accomplish an excellent U-port Ethernet-based signal emulation in addition to integration into your U inhabitants command program, inside the detection with PHSOE linked equipment exclusively in their peripheral gadgets U Ethernet interface as well as a very simple signal can.
