Uburyo bwo Guhitamo Ibikoresho bya PON by'Imishinga Ihuriweho ya FTTH CATV

Imishinga yo kuvugurura umuyoboro w'itumanaho ihora izana ibibazo bikomeye ku bakoresha porogaramu zihuza n'abaguzi ba interineti. Amatsinda menshi y'abahanga ahura n'ibibazo bikomeye mu buzima iyo ateganya gushyiraho cyangwa kuvugurura imiyoboro ya optique idakora, cyane cyane ku mbuga zisaba imiyoboro ya interineti yo mu rugo na televiziyo ya CATV. Nk'uko byavuzwe cyane mu nyandiko za tekiniki z'inganda, ikibazo cy'uburebure bw'umuyoboro w'amashanyarazi, imikorere ya DBA n'uburyo bwo kongera gukoresha ODN ni byo bintu bibabaza cyane mu gushyiraho PON ivanze.

Iyi nkuru ntabwo izibanda ku bisobanuro birambuye bya protocole igoye. Ahubwo, itanga inama zifatika zo kugereranya no guhitamo ibikoresho by'ikoranabuhanga ku mishinga ya FTTH CATV ikora. Waba uri kubaka umuyoboro mushya cyangwa urimo kuvugurura ibikorwa remezo bya kera, gusobanukirwa ibyiza n'ibibi bya buri gisubizo bishobora kugufasha kwirinda guhomba gukabije aho ukorera.

Imbogamizi z'ingenzi zo kohereza FTTH CATV PON

Mbere yo kwihutira kugereranya ibicuruzwa, ni ngombwa gukemura inzitizi zisanzwe inzobere mu bya siyansi zikomeza guhura nazo. Ibi bibazo bifatika akenshi bigena amahame ya PON ajyanye neza n'umushinga wawe.

Ubwa mbere,kongera gukoresha ibikorwa remezo bya kera. Umubare munini w'ahantu hasanzwe ha FTTH hubatswe hafi ya GPON. Ba nyir'umushinga bizeye kugumana insinga za fibre, ibice by'amashanyarazi n'udusanduku two gusana kugira ngo bagabanye ingengo y'imari yo kubaka. Ariko, si ibikoresho byose bishobora gushyigikira kubaho neza kw'ibimenyetso bya optique bishaje n'ibishya. Guhuza nabi bizatera ONT idakora kuri interineti kandi videwo ya CATV idakora neza.

Icya kabiri,umuvuduko wa interineti ya serivisi nyinshiImbuga zigezweho zifite byinshi byo gukoresha interineti gusa. Imiyoboro ya IPTV, analog CATV overlay, VoIP voice na internet yihuta cyane ikoresha fibre imwe. Gahunda mbi ya bandwidth izazana ubunararibonye butunguranye bwa videwo, buhinduka isoko rikomeye ry'ibibazo bivuye ku bafatabuguzi.

Icya gatatu,igihe cy'ishoramari kidahinduka mu gihe kizazaAbakoresha n'abahuza ibikorwa bagomba kuringaniza ikiguzi cy'umushinga n'igihe cy'imyaka 5-8. Guhitamo ibikoresho bike cyane bishobora gutuma bisimburana mu myaka myinshi, mu gihe kugura ibikoresho birenze urugero bitera gutakaza imari bitari ngombwa.

Igereranya ry'uruhande ku rundi: GPON vs XGS PON kuri FTTH CATV Scenarios

Ikintu cy'isuzuma	OLT‑G16V (GPON OLT Yera)	XGSPON‑08P (XG(S)‑PON Combo OLT)
Igipimo cya PON Port	Hasi 2.488Gbps / Hejuru 1.244Gbps (ITU - T G.984)	10Gbps ingana (uburyo bwa XGS PON); ihuza inyuma na 2.488G/1.244G (uburyo bwa GPON)
Umubare w'ibikoresho bya PON Port	Imbuga za GPON 16 ×	Imbuga 8 × Combo XG(S)‑PON/GPON
Ihuza rya Uplink	4×10GE(SFP+) + ​​8×GE imiyoboro y'umuringa	2×100G QSFP28 + 8×10GE/GE SFP ishyirwa ku murongo
Uburyo bwo kongera gukoresha GPON ODN buriho	Ikorana na GPON splitters zisanzwe; nta filter y'inyongera ikenewe kuri network ya GPON yonyine	Ishyigikira GPON ODN isanzweho; irakenewe mu gushungura GPON/XGS PON ivanze mu gukwirakwiza co-fiber
Guhuza uburebure bwa CATV bwa 1550nm	Ishyigikira uburebure bwa CATV bwa 1550nm; ikoreshwa cyane mu mishinga ya FTTH CATV triple play	Ishyigikira uburebure bwa CATV bwa 1550nm; gutandukanya uburebure bw'umuraba bigomba gusuzumwa mu buryo buvanze
Igipimo cy'itandukaniro ry'ibyiciro	Ibikoresho ntarengwa 1:128; 1:64 ni byiza kuri interineti ihamye + serivisi zivanze za CATV zikora	Ibikoresho ntarengwa 1:256; 1:64–1:128 birasabwa; isuzuma ryuzuye ry'uburinzi rirakenewe mu bijyanye no gupima CATV overlay scenarios
Ibintu bisanzwe byo gushyira abantu mu bikorwa by'ingenzi	FTTH nini yo mu cyaro, ihuriro ry'abaturage, imishinga ihenze yo gukora ibikorwa bitatu hamwe n'abafatabuguzi ba GPON benshi	Amazu y’ubucucike buhanitse, amahoteli, imiyoboro y’ibigo, imiyoboro mishya y’umuvuduko mwinshi isaba umuyoboro wa 10G uhoraho mu gihe kizaza.

Mu gihe usuzuma amahitamo ya hardware, ntukibande gusa ku bipimo by'ibiciro bya nominemu. Ku mishinga ya FTTH CATV ihuriweho, shyira imbaraga mu gusesengura urumuri rwubatswemo hamwe n'imikorere ya DBA mu gihe cyo guteguraIbikoresho bya 10G PON OLTIbikoresho byinshi bihendutse ku isoko bigabanya amahirwe kuri izi modules ebyiri, bigatuma videwo ihagarara kenshi bitewe n'umutwaro munini wa serivisi mu gihe nyacyo.

Inzira yo Gufata Ibyemezo: Ni iyihe ngamba ukwiye guhitamo?

Hitamo GPON niba:

Umushinga wawe ugamije gushyira interineti mu cyaro cyangwa kuvugurura mu buryo buciriritse. Umuyoboro wa ODN usanzwe uhari urahamye, icyifuzo cy'umuyoboro wa interineti w'abafatabuguzi kiri munsi ya 300Mbps kuri buri rugo, kandi CATV ni cyo kintu cy'ingenzi ukeneye. GPON imaze kwegeranya uburambe bwinshi bwo gushyiramo ibikoresho byemejwe n'urubuga. Ibikoresho bisimbura ibindi n'ibikoresho byo kubungabunga biroroshye kubibona ku masoko mpuzamahanga.

Hitamo XGS‑PON niba:

Ukorera mu mazu y’ubucucike bunini, mu bigo binini by’amahoteli cyangwa mu duce tw’ubucuruzi dutandukanye. Abakoresha ba nyuma bakeneye umuyoboro wa gigabit uhuza imiterere ya interineti, kandi witeze ko ubushobozi bwa network bushobora gukora mu myaka 6-8 iri imbere. Muri iki gihe,XGS‑PON ikorana na ONT hamwe na CATV portIzana agaciro gasanzwe mu gihe kirekire. Wibuke: GPON na XGS PON bivanze bikoresha fibre imwe bisaba modules za filter zikwiye muri OLT, ntusimbuke iyi configuration kugira ngo uzigame ikiguzi cy'igihe gito.

Irinde kohereza ibintu mu buryo butari bwo

Ntugahatire gukoresha XGS-PON mixed mode niba itsinda ryawe riri aho ridafite uburambe bujyanye no gukemura ibibazo bya PON. Kwivanga kw'uburebure bw'umuraba utari ukwawo bizatuma bigorana kongera gukora amakosa ahoraho agatwara abakozi benshi nyuma yo kugurisha.

Amasomo yo mu bikorwa by'imishinga yo ku isi nyayo

Umwe mu bahuza sisitemu bo mu majyepfo y'uburasirazuba yigeze gutegura kuvugurura umuyoboro w'itumanaho ku nkombe z'inyanja. Mbere na mbere, itsinda ryatekereje gushyira XGS-PON mixed-mode ku muyoboro wa fibre wa GPON wa mbere. Nyuma yo gusuzuma ingaruka z'ubuhanga zakozwe mu nganda, bakoze ibizamini bito ku rwego rwo hejuru. Ibizamini bya mbere byagaragaje ihindagurika ry'ibimenyetso nta modules zikwiye zo kuyungurura. Amaherezo, bahisemo ibikoresho bya OLT bifite filters za optique zihuriweho, bagumana ibice byinshi by'umwimerere bya ODN bongeraho serivisi ya XGS-PON ku nyubako z'abashyitsi bakomeye, mu gihe bagumana GPON mu turere dukoreshwa muri rusange. Ibi byagabanyije ingengo y'imari, ituze n'ubushobozi bwo kwagura mu gihe kizaza.
