XPON ni iki

Nka gisekuru gishya cya optique ya fibre optique, XPON ifite ibyiza byinshi mukurwanya kwivanga, ibiranga umurongo, intera igera, kubungabunga no gucunga, nibindi.XPON optique yo gukoresha tekinoroji irakuze cyane EPON na GPON byombi bigizwe nibiro bikuru OLT, ibikoresho byabakoresha kuruhande rwa ONU hamwe numuyoboro wa optique wo gukwirakwiza ODN.Muri byo, umuyoboro wa ODN nibikoresho ni igice cyingenzi cya XPON ihuriweho, ikubiyemo gushiraho no gushyira mu bikorwa imiyoboro mishya ya optique.Ibikoresho bifitanye isano na ODN hamwe nigiciro cyurusobe byabaye ibintu byingenzi bibuza porogaramu XPON.

Igitekerezo

Kugeza ubu, inganda muri rusange zifite ikoranabuhanga rya xPON zirimo EPON na GPON.

Ikoranabuhanga rya GPON (Gigabit-CapablePON) nigisekuru cyanyuma cyumuyoboro mugari wa pasiporo optique ihuriweho hamwe hashingiwe kuri ITU-TG.984.x.Ifite ibyiza byinshi nkumuyoboro mwinshi, gukora neza, gukwirakwiza cyane, hamwe nabakoresha interineti.Abakoresha babifata nk'ikoranabuhanga ryiza ryo kumenya umurongo mugari no guhindura byimazeyo serivisi za serivise.Igipimo ntarengwa cyo hasi ya GPON ni 2.5Gbps, umurongo wo hejuru ni 1.25Gbps, naho igipimo kinini cyo gutandukana ni 1:64.

EPON ni ubwoko bwikoranabuhanga rigaragara ryogukoresha umurongo mugari, rimenyesha serivisi ihuriweho namakuru, amajwi na videwo binyuze muri sisitemu imwe ya optique ya fibre optique, kandi ifite ubukungu bwiza.EPON izahinduka uburyo rusange bwo gukoresha umurongo mugari.Bitewe n'ibiranga imiterere y'urusobe rwa EPON, inyungu zidasanzwe zo kugera ku muyoboro mugari kugera ku rugo, hamwe no guhuza ibinyabuzima bisanzwe hamwe n'imiyoboro ya mudasobwa, impuguke ku isi yose zemeranya ko imiyoboro ya optique ari ugusohora “imiyoboro itatu muri imwe” kandi igisubizo cyamakuru makuru.Uburyo bwiza bwo kohereza kuri "kilometero yanyuma".

Igisekuru kizaza PON sisitemu ya sisitemu xPON:

Nubwo EPON na GPON bafite tekinoroji zabo zitandukanye, bafite imiyoboro imwe ya topologiya hamwe nuburyo bwo kuyobora imiyoboro.Byombi byerekanwe kumurongo umwe wa optique yo kubona imiyoboro kandi ntabwo ari uguhuza.Igisekuru kizaza cya PON sisitemu ya xPON irashobora gushyigikira icyarimwe.Ibipimo byombi, ni ukuvuga, ibikoresho bya xPON birashobora gutanga uburyo butandukanye bwo kubona PON ukurikije ibyo abakoresha bakeneye bitandukanye, kandi bigakemura ikibazo cyo kudahuza tekinoloji zombi.Muri icyo gihe, sisitemu ya xPON itanga urubuga ruhuriweho rwo gucunga imiyoboro ishobora gucunga ibikenerwa mu bucuruzi butandukanye, kumenya serivisi zuzuye (harimo ATM, Ethernet, TDM) ubushobozi bwo gushyigikira garanti ya QoS, kandi igashyigikira itumanaho rya tereviziyo ya televiziyo ikoresheje WDM;icyarimwe, irashobora guhita imenya EPON, ikarita ya GPON yongeweho kandi ikuweho;birahuye rwose numuyoboro wa EPON na GPON icyarimwe.Ku bayobozi b'urusobe, imiyoborere n'iboneza byose ni iby'ubucuruzi, utitaye ku itandukaniro rya tekiniki riri hagati ya EPON na GPON.Nukuvuga ko gushyira mubikorwa tekinike ya EPON na GPON bisobanutse mubuyobozi bwurusobe, kandi itandukaniro riri hagati yibi byombi rirakingiwe kandi rihabwa urwego rwo hejuru rwihuriweho.Ihuriro rihuriweho nogucunga imiyoboro nimwe mubyiza byingenzi byiyi sisitemu, mubyukuri bigahuriza hamwe guhuza tekinoloji ebyiri zitandukanye za PON kurwego rwo gucunga imiyoboro.

Ibipimo nyamukuru byurusobe rwa xPON nibi bikurikira:

Ubushobozi bwo gufasha-serivisi nyinshi: kugera kuri serivisi yuzuye (harimo ATM, Ethernet, TDM) ubushobozi bwingoboka hamwe na QoS garanti ikomeye, kugirango ubucuruzi butangwe neza, ushyigikire imiyoboro ya tereviziyo ya televiziyo binyuze muri WDM;

Imiterere

Sisitemu ya optique ya fibre optique ni sisitemu yo gukwirakwiza fibre optique igizwe na optique yumurongo wa optique (OLT), umuyoboro wo gukwirakwiza optique (ODN), hamwe numuyoboro wa optique (ONU), bita sisitemu ya PON.Moderi ya sisitemu ya PON yerekanwe mubishusho 1.

Sisitemu ya PON ifata ingingo-kuri-kugwiza imiyoboro y'urusobekerane, ikoresha imiyoboro ya optique yo gukwirakwiza imiyoboro nk'itumanaho rikoresha imiyoboro, ikoresha uburyo bwo gutangaza amakuru kuri downlink, hamwe na TDM ikora muri uplink, ikamenya itumanaho rya fibre imwe.Ugereranije numuyoboro gakondo winjira, sisitemu ya PON irashobora kugabanya ikoreshwa ryokugera mucyumba cya mudasobwa no kugera ku nsinga za optique, kongera imiyoboro y’urusobekerane, kongera igipimo cyo kugera, kugabanya igipimo cyo kunanirwa kw'imirongo n'ibikoresho byo hanze, kandi kunoza ubwizerwe bwa sisitemu.Mugihe kimwe, irazigama kandi amafaranga yo kubungabunga, sisitemu ya PON rero niyo tekinoroji nyamukuru yo gukoresha ya NGB inzira ebyiri.

Ukurikije uburyo butandukanye bwo kohereza ibimenyetso bya sisitemu, birashobora kwitwa xPON, nka APON, BPON, EPON, GPON na WDM-PON.GPON na EPON byoherejwe henshi kwisi, kandi hariho na progaramu nini muguhindura amaradiyo na tereviziyo inzira ebyiri.WDM-PON ni sisitemu ikoresha imiyoboro yigenga yigenga hagati ya OLT na ONU kugirango ikore ingingo-ku-ngingo.Ugereranije na TDM- nka EPON na GPON, PON na WDM-PON bafite ibyiza byumuvuduko mwinshi, protocole ikorera mu mucyo, umutekano no kwizerwa, hamwe nubunini bukomeye.Nicyerekezo cyiterambere kizaza.Mugihe gito, kubera amahame akomeye ya WDM-PON, ibiciro byibikoresho biri hejuru, hamwe nigiciro kinini cya sisitemu, ntabwo iracyafite ibisabwa kugirango binini binini.

Ibipimo byingenzi bya tekinike ya xPON

CapacityUbushobozi bwa sisitemu: Sisitemu ifite ubushobozi bunini bwo guhinduranya IP (30G), itanga imiyoboro ya 10G ya Ethernet, kandi buri OLT irashobora gushyigikira PON 36;

InterfaceIbikorwa bya serivisi byinshi: shyigikira TDM, ATM, Ethernet, CATV, kandi utange ingwate ikomeye ya QoS, irashobora kwinjiza neza ubucuruzi buriho, kandi igashyigikira rwose kuzamura ubucuruzi neza;

③ Sisitemu yo kwizerwa cyane nibisabwa kuboneka: Sisitemu itanga uburyo bwo guhitamo 1 + 1 bwo kurinda uburyo bwo kuzuza ibisabwa kugirango umuyoboro w'itumanaho wizere neza, kandi igihe cyo guhinduranya kiri munsi ya 50m;

RangeIbikorwa bikora: 10-20km ya diameter y'urusobekerane irashobora gushyirwaho kugirango ihuze byuzuye ibisabwa numuyoboro winjira;

PlatformUrubuga rukomatanyirijwe hamwe rwo gucunga porogaramu: Kuburyo butandukanye bwo kugera, ifite urubuga rumwe rwo gucunga imiyoboro.
