Kunethiwekhi yanamuhla yokubonaizinhlobo, ukufika kwei-fiber optic splitterinikela ekusizeni abasebenzisi ukukhulisa ukusebenza kwamasekhethi enethiwekhi yokubona.I-Fiber optic splitter, ebizwa nangokuthi i-optical splitter, noma i-beam splitter, iyinhlanganisela ehlanganisiweigagasi-umhlahlandlelaidivayisi yokusabalalisa amandla okukhanya engahlukanisa i-beam yokukhanya yesigameko ibe amalambu okukhanya amabili noma ngaphezulu, futhi okuphambene nalokho, aqukethe okokufaka okuningi neziphetho zokuphumayo.I-Optical splitter idlale indima ebalulekile kumanethiwekhi okusebenza okusebenza (njenge-EPON, GPON, BPON, FTTX, FTTH, njll.) ngokuvumela isixhumi esibonakalayo se-PON ukuthi kwabelwane ngaso phakathi kwababhalisile abaningi.
Isebenza Kanjani I-Fiber Optic Splitter?
Ngokuvamile, lapho isignali yokukhanya idlulisa ngefayibha yemodi eyodwa, amandla okukhanya awakwazi ukugxila ngokuphelele kumongo wefayibha.Inani elincane lamandla lizosakazwa ngokuhlanganiswa kwe-fiber.Okusho ukuthi, uma imicu emibili isondelene ngokwanele, ukukhanya okudlulisela ku-fiber optical kungangena kwenye i-optical fiber.Ngakho-ke, indlela yokwabiwa kabusha kwesignali ye-optical ingafinyelelwa kumafayibha amaningi, okuyindlela i-fiber optic splitter eba khona ngayo.
Uma sikhuluma ngokuqondile, i-passive optical splitter ingahlukanisa, noma ihlukanise, i-beam yokukhanya yesigameko ibe yimishayo eminingana yokukhanya ngesilinganiso esithile.Ukumiswa kokuhlukaniswa okungu-1×4 okwethulwe ngezansi kuyisakhiwo esiyisisekelo: ukuhlukanisa i-beam yokukhanya kwesigameko kusukela kukhebula yefayibha yokufaka eyodwa ibe yimishayo yokukhanya emine futhi iwadlulise ngezintambo ezine zefayibha eziphuma ngazinye.Isibonelo, uma ikhebuli ye-fiber optic yokufaka iphethe umkhawulokudonsa ongu-1000 Mbps, umsebenzisi ngamunye ekugcineni kwezintambo zefayibha eziphumayo angasebenzisa inethiwekhi enomkhawulokudonsa ongu-250 Mbps.
Isihlukanisi esibonakalayo esinokuhlelwa kokuhlukaniswa okungu-2 × 64 siyinkimbinkimbi kakhulu kunokuhlelwa kokuhlukaniswa okungu-1×4.Kunamatheminali amabili okokufaka kanye namatheminali angamashumi ayisithupha nane okukhiphayo ku-splitter ye-optical in 2×64 yokuhlukanisa.Umsebenzi wayo ukuhlukanisa imishayo yokukhanya yesigameko emibili isuka ezintamboni zokufaka zefayibha zokufaka ezimbili zibe yimishayo yokukhanya engamashumi ayisithupha nane futhi iwadlulise ngezintambo ezilula ezingamashumi ayisithupha nane zokukhishwa komuntu ngamunye.Ngokukhula okusheshayo kwe-FTTx emhlabeni wonke, imfuneko yokuhlelwa kokuhlukaniswa okukhudlwana kumanethiwekhi iye yanda ukuze inikeze ababhalisile abaningi.
Izinhlobo ze-Fiber Optic Splitter
Kuhlukaniswa ngesitayela sephakheji
I-opticalizihlukanisiingaqedwa ngezinhlobo ezahlukene zezixhumi, futhi iphakheji eyinhloko ingaba uhlobo lwebhokisi noma uhlobo lweshubhu engagqwali.Ibhokisi lokuhlukanisa i-fiber optic livamise ukusetshenziswa ngekhebula lobubanzi obungu-2mm noma obu-3mm, kanti elinye livamise ukusetshenziswa lihlanganiswe nezintambo ezinobubanzi obungu-0.9mm bangaphandle.Ngaphandle kwalokho, inokucushwa okuhlukene okuhlukene okuhlukene, okufana ne-1×2, 1×8, 2×32, 2×64, njll.
Kuhlukaniswa nge-Transmission Medium
Ngokwezisetshenziswa ezihlukene zokudlulisela, kukhona i-single mode optical splitter kanye ne-multimode optical splitter.I-multimode optical splitter isho ukuthi i-fiber yenzelwe ukusebenza okungu-850nm kanye ne-1310nm, kanti imodi eyodwa isho ukuthi i-fiber ilungiselelwe ukusebenza kwe-1310nm kanye ne-1550nm.Ngaphandle kwalokho, ngokusekelwe ekwehlukeni kwe-wavelength esebenzayo, kukhona iwindi elilodwa kanye nezihlukanisi zewindi elikabili—okokuqala ukusebenzisa ubude begagasi obusebenzayo obubodwa, kuyilapho i-fiber optic splitter yokugcina inobude obubili obusebenzayo.
Kuhlukaniswa nge-Manufacturing Technique
Isihlukanisi se-FBT sisekelwe kubuchwepheshe bendabuko ukushisela imicu eminingana ndawonye ukusuka ohlangothini lwefayibha, okufaka izindleko eziphansi.Izihlukanisi ze-PLCisekelwe kubuchwepheshe besekethe ye-planar lightwave, etholakala ngezilinganiso ezihlukahlukene zokuhlukaniswa, okuhlanganisa 1:4, 1:8, 1:16, 1:32, 1:64, njll, futhi ingahlukaniswa ngezinhlobo eziningana ezifana nqunuIsihlukanisi se-PLC, isihlukanisi se-PLC esingavimbeli, isihlukanisi se-ABS, isihlukanisi sebhokisi le-LGX, isihlukanisi se- fanout PLC, isihlukanisi se-mini plug-in uhlobo lwe-PLC, njll.

Isicelo se-Fiber Optic Splitter ku-PON Networks
Izihlukanisi ze-Optical, ezivumela isignali ku-fiber optical ukuthi zisatshalaliswe phakathi kwemicu emibili noma ngaphezulu yokubona ngokuhlelwa okuhlukene kokuhlukanisa (1×N noma i-M×N), isetshenziswe kabanzi kumanethiwekhi e-PON.I-FTTH ingesinye sezimo ezijwayelekile zohlelo lokusebenza.Isakhiwo esijwayelekile se-FTTH yilesi: Itheminali ye-Optical Line (OLT) etholakala ehhovisi elimaphakathi;I-Optical Network Unit (ONU) etholakala ekugcineni komsebenzisi;I-Optical Distribution Network (ODN) ixazululwe phakathi kokubili kwangaphambilini.Isihlukanisi esibonakalayo sivamise ukusetshenziswa ku-ODN ukusiza abasebenzisi bokugcina abaningi babelane ngesixhumi esibonakalayo se-PON.
Ukuthunyelwa kwenethiwekhi ye-Point-to-multipoint FTTH kungabuye kuhlukaniswe kube ukulungiselelwa kwesihlukanisi esimaphakathi (isiteji esisodwa) noma (izigaba eziningi) engxenyeni yokusabalalisa yenethiwekhi ye-FTTH.Ukucushwa kwesihlukanisi esimaphakathi ngokuvamile kusebenzisa isilinganiso esihlanganisiwe sokuhlukanisa esingu-1:64, nesihlukanisi esingu-1:2 ehhovisi elimaphakathi, kanye no-1:32 endaweni ebiyelwe endaweni yangaphandle (OSP) njengekhabhinethi.Ukucushwa kwe-cascaded noma okusabalalisiwe kwesihlukanisi ngokuvamile akunazihlukanisi ehhovisi elimaphakathi.Imbobo ye-OLT ixhunywe/ihlanganiswe ngqo nefayibha yesitshalo yangaphandle.Izinga lokuqala lokuhlukanisa (1:4 noma 1:8) lifakwe ekuvaleni, hhayi kude nehhovisi eliphakathi;izinga lesibili lezihlukanisi (1:8 noma 1:16) lisemabhokisini etheminali, eduze nezakhiwo zekhasimende.Ukuhlukaniswa Okumaphakathi Ngokuhlukana Nokusatshalaliswa Kumanethiwekhi e-PON Asekelwe ku-FTTH kuzophinde kubonise lezi zindlela ezimbili zokuhlukanisa ezamukela izihlukanisi ze-fiber optic.
Ungasikhetha kanjani i-Fiber Optic Splitter efanele?
Ngokuvamile, i-high fiber optic splitter idinga ukuphumelela uchungechunge lokuhlolwa okuqinile.Izinkomba zokusebenza ezizothinta i-fiber optic splitter zimi kanje:
Ukulahlekelwa kokufakwayo: Ibhekisela ku-dB yokukhipha ngakunye ngokuhlobene nokulahlekelwa kokubona okokufaka.Ngokuvamile, inani lokulahlekelwa lokufaka lincane, kuba ngcono ukusebenza kwesihlukanisi.
Ukulahlekelwa kokubuyisela: Okwaziwa nangokuthi ukulahlekelwa kokubonisa, kubhekisela ekulahlekelweni kwamandla esignali yokubona ebuyiselwayo noma eboniswa ngenxa yokungaqhubeki kwefayibha noma ulayini wokudlulisela.Ngokuvamile, ukulahlekelwa okukhulu kokubuyisela, kungcono.
Isilinganiso sokuhlukanisa: Kuchazwa njengamandla okukhiphayo wembobo yokukhipha yesihlukanisi ohlelweni lokusebenza lwesistimu, ehlobene nobude bewaveli bokukhanya okudlulisiwe.
Ukuhlukaniswa: Kubonisa indlela elula yokuhlukanisa i-optical kwezinye izindlela zokubonwa kwe-optical signal isolation.
Ngaphandle kwalokho, ukufana, ukuqondisa, kanye nokulahleka kwe-PDL kwe-polarization nakho kuyimingcele ebalulekile ethinta ukusebenza kwesihlukanisi sensimbi.
Ngokukhethwa okuthile, i-FBT ne-PLC yizinketho ezimbili eziyinhloko zeningi labasebenzisi.Umehluko phakathi kwe-FBT splitter vs PLC splitter ngokuvamile usekubude begagasi obusebenzayo, isilinganiso sokuhlukanisa, ukuncishiswa kwe-asymmetric igatsha ngalinye, izinga lokuhluleka, njll. Uma sikhuluma nje, isihlukanisi se-FBT sithathwa njengesixazululo esingabizi kakhulu.Isihlukanisi se-PLC esinokuguquguquka okuhle, ukuzinza okuphezulu, izinga lokuhluleka eliphansi, nezinga lokushisa elibanzi lingasetshenziswa ezinhlelweni zokusebenza eziminyana kakhulu.
Ezindlekweni, izindleko zezihlukanisi ze-PLC ngokuvamile ziphakeme kunezihlukanisi ze-FBT ngenxa yobuchwepheshe bokukhiqiza obuyinkimbinkimbi.Ezimweni ezithile zokucushwa, ukuhlelwa kokuhlukaniswa okungezansi kwe-1×4 kuyelulekwa ukuthi kusetshenziswe isihlukanisi se-FBT, kuyilapho ukuhlelwa kokuhlukaniswa okungaphezulu kwe-1×8 kunconyelwe izihlukanisi ze-PLC.Ngokudlulisa okukodwa noma okubili kwe-wavelength, isihlukanisi se-FBT singonga imali.Ngokudluliswa kwe-Broadband ye-PON, isihlukanisi se-PLC siyisinqumo esingcono uma kucatshangelwa izidingo zokwandiswa nokuqapha okuzayo.
Amazwi okuphetha
Izihlukanisi ze-Fiber optic zinika amandla isignali ku-fiber optical ukuthi isatshalaliswe phakathi kwemicu emibili noma ngaphezulu.Njengoba izihlukanisi zingenazo izinto zikagesi futhi azidingi amandla, ziyingxenye ebalulekile futhi zisetshenziswa kabanzi kumanethiwekhi amaningi we-fiber-optic.Ngakho-ke, ukukhetha izihlukanisi ze-fiber optic ukusiza ukwandisa ukusetshenziswa kahle kwengqalasizinda ye-optical kuyisihluthulelo sokuthuthukisa i-architecture yenethiwekhi ezohlala kahle esikhathini esizayo.
