Niki Fibre Optic Splitter?

Muri uyu munsi wa optiqueImiterere, ukuza kwafibre optiqueigira uruhare mu gufasha abakoresha gukora cyane imikorere yumurongo wa optique.Fibre optique itandukanya, nayo yitwa optique itandukanya, cyangwa ibiti bitandukanya, ni byoseumurongoibikoresho bya optique yo gukwirakwiza ibikoresho bishobora kugabanya urumuri rumuri mumirongo ibiri cyangwa myinshi yumucyo, naho ubundi, ikubiyemo ibintu byinshi byinjira nibisohoka.Gutandukanya optique byagize uruhare runini mumiyoboro ya optique (nka EPON, GPON, BPON, FTTX, FTTH, nibindi) mukwemerera interineti imwe ya PON gusangira mubiyandikishije benshi.

Nigute Fibre Optic Splitter ikora?

Muri rusange, iyo ikimenyetso cyumucyo kinyuze muburyo bumwe bwa fibre, ingufu zumucyo ntizishobora kuba rwose muri fibre yibanze.Ingufu nkeya zizakwirakwizwa hifashishijwe fibre.Nukuvuga ko, niba fibre ebyiri zegeranye bihagije, urumuri rwohereza muri fibre optique rushobora kwinjira mubindi fibre optique.Kubwibyo, tekinike yo kugabura ibimenyetso bya optique irashobora kugerwaho muri fibre nyinshi, nuburyo fibre optique itandukana.

Mu buryo bwihariye, ibice bya optique bitandukanya bishobora gutandukana, cyangwa gutandukanya, urumuri rwabaye rumuri mumatara menshi kumurongo runaka.Ibice 1 × 4 byacitsemo ibice byerekanwe hepfo nuburyo bwibanze: gutandukanya urumuri rumuri rwabaye numurongo umwe winjiza fibre mumirongo ine yumucyo no kubwohereza mumashanyarazi ane asohoka.Kurugero, niba insinga ya fibre optique itwara umurongo wa 1000 Mbps, buri mukoresha kurangiza insinga za fibre zishobora gukoresha umuyoboro hamwe na 250 Mbps.

Amacakubiri ya optique hamwe na 2 × 64 igabanyijemo ibice ni bike cyane bigoye kuruta ibice 1 × 4 bigabanijwe.Hano haribintu bibiri byinjira hamwe na mirongo itandatu na bine bisohoka muri optique ya optique muri 2 × 64 ibice.Igikorwa cyayo ni ugucamo ibice bibiri byamatara yibyuma biva mumigozi ibiri yinjiza fibre mumirongo mirongo itandatu na bine yumucyo hanyuma ikohereza mumashanyarazi ya fibre mirongo itandatu na bane.Hamwe niterambere ryihuse rya FTTx kwisi yose, ibisabwa kugirango ibice binini bigabanuke mumiyoboro byiyongereye kugirango bikorere abafatabuguzi benshi.

Ubwoko bwa Fibre optique

Bishyizwe muburyo bwa Package

AmashanyarazigutandukanaIrashobora guhagarikwa nuburyo butandukanye bwihuza, kandi pake yibanze irashobora kuba agasanduku k'ubwoko cyangwa ubwoko bwa tube butagira umwanda.Isanduku ya fibre optique isanzwe ikoreshwa hamwe na kabili ya diameter ya 2mm cyangwa 3mm, mugihe iyindi isanzwe ikoreshwa ifatanije ninsinga za diameter 0.9mm.Uretse ibyo, ifite ibice bitandukanye bitandukanye, nka 1 × 2, 1 × 8, 2 × 32, 2 × 64, nibindi.

Bishyizwe hamwe na Transmission Medium

Ukurikije uburyo butandukanye bwo kohereza, hariho uburyo bumwe optique itandukanya na multimode optique.Multimode optique itandukanya yerekana ko fibre itezimbere kubikorwa 850nm na 1310nm, mugihe uburyo bumwe umuntu asobanura ko fibre itezimbere kubikorwa 1310nm na 1550nm.Uretse ibyo, ukurikije itandukaniro ryumurongo utandukanye, hariho idirishya rimwe hamwe nidirishya rya optique itandukanya-iyambere ni ugukoresha uburebure bwumurongo umwe, mugihe fibre optique itandukanya hamwe nuburebure bubiri bukora.

Byashyizwe mubikorwa na tekinike yo gukora

Gutandukanya FBT bishingiye ku buhanga gakondo bwo gusudira fibre nyinshi hamwe kuruhande rwa fibre, hagaragaramo ibiciro biri hasi.Gutandukanya PLCishingiye kuri tekinoroji yumuzunguruko wa planar, iboneka muburyo butandukanye bwo gutandukana, harimo 1: 4, 1: 8, 1:16, 1:32, 1:64, nibindi, kandi birashobora kugabanywa muburyo butandukanye nka yambaye ubusaGutandukanya PLC, ibice bitagira umupaka bya PLC, gutandukanya ABS, gutandukanya agasanduku ka LGX, gutandukanya abafana ba PLC, mini plug-in ubwoko bwa PLC itandukanya, nibindi.

Reba imbonerahamwe ikurikira ya PLC Splitter vs FBT Igereranya:

Fibre Optic Splitter Porogaramu muri PON Network

Amacakubiri ya optique, ashoboza ibimenyetso kuri fibre optique gukwirakwizwa hagati ya fibre ebyiri cyangwa nyinshi za optique zifite ibice bitandukanye byo gutandukana (1 × N cyangwa M × N), byakoreshejwe cyane mumiyoboro ya PON.FTTH nimwe mubisanzwe bisanzwe bikoreshwa.Ubwubatsi busanzwe bwa FTTH ni: Optical Line Terminal (OLT) iherereye mubiro bikuru;Igice cya Optical Network Unit (ONU) giherereye kumukoresha wa nyuma;Umuyoboro mwiza wo gukwirakwiza (ODN) wakemuye hagati yabiri ibanza.Gutandukanya optique ikoreshwa kenshi muri ODN kugirango ifashe abakoresha benshi ba nyuma gusangira interineti ya PON.

Ingingo-kuri-kugwiza imiyoboro ya FTTH yoherejwe irashobora kugabanywa mubice bikomatanyirijwe hamwe (icyiciro kimwe) cyangwa ibishushanyo mbonera (ibice byinshi) ibice byo kugabana mugice cyo gukwirakwiza umuyoboro wa FTTH.Ibice bigizwe nibice bisanzwe bikoresha ikigereranyo cyo gutandukanya 1:64, hamwe na 1: 2 mu biro bikuru, na 1:32 mukigo cyo hanze (OSP) gikikijwe nkinama y'abaminisitiri.Ibikoresho bisobekeranye cyangwa byagabanijwe mubisanzwe nta bitandukanya mubiro bikuru.Icyambu cya OLT cyahujwe / giteye neza kuri fibre yo hanze.Urwego rwa mbere rwo gutandukana (1: 4 cyangwa 1: 8) rwashyizwe mugufunga, utari kure yibiro bikuru;urwego rwa kabiri rwo gutandukana (1: 8 cyangwa 1:16) ruherereye kumasanduku yanyuma, hafi yabakiriya.Gutandukanya Hagati na Gukwirakwiza Gutandukanya muri PON ishingiye kuri FTTH Networks bizarushaho kwerekana ubu buryo bubiri bwo gutandukanya bukoresha fibre optique.

Nigute ushobora guhitamo neza fibre optique?

Muri rusange, fibre optique itandukanya ikeneye gutsinda urukurikirane rwibizamini bikomeye.Ibipimo byerekana imikorere bizagira ingaruka kuri fibre optique nibi bikurikira:

Igihombo cyo gushiramo: Yerekeza kuri dB ya buri gisohoka ugereranije ninjiza yatakaye.Mubisanzwe, ntoya kwinjiza igihombo agaciro, nibikorwa byiza byo gutandukana.

Gutakaza igihombo: Bizwi kandi nkigihombo cyo gutekereza, bivuga gutakaza ingufu za signal optique isubizwa cyangwa igaragazwa kubera guhagarara muri fibre cyangwa umurongo wohereza.Mubisanzwe, uko igihombo kinini cyagaruka, nibyiza.

Ikigereranyo cyo kugabana: Byasobanuwe nkibisohoka imbaraga zo gutandukanya icyambu gisohoka muri sisitemu ya porogaramu, ifitanye isano nuburebure bwumucyo woherejwe.

Kwigunga: Yerekana inzira yoroheje optique igabanya izindi nzira za optique zo guhitamo ibimenyetso bya optique.

Uretse ibyo, uburinganire, icyerekezo, hamwe na PDL igihombo nacyo ni ibipimo byingenzi bigira ingaruka kumikorere yo gutandukanya ibiti.

Kubihitamo byihariye, FBT na PLC nuburyo bubiri bwingenzi kubakoresha benshi.Itandukaniro riri hagati ya FBT itandukanya vs PLC itandukanijwe mubisanzwe iri muburebure bwumurongo wumurongo, igabanywa ryikigereranyo, kwiyongera kwa asimmetrike kuri buri shami, igipimo cyo gutsindwa, nibindi. Nkubwije ukuri, gutandukanya FBT bifatwa nkigisubizo cyigiciro.Gutandukanya PLC yerekana ibintu byoroshye guhinduka, gutuza kwinshi, igipimo gito cyo kunanirwa, hamwe nubushyuhe bwagutse burashobora gukoreshwa mubikorwa byinshi.

Kubikoresha, ibiciro bya PLC bigabanije muri rusange birenze ibyo gutandukanya FBT bitewe nubuhanga bugoye bwo gukora.Muburyo bwihariye bwo kuboneza ibice, ibice bitandukanijwe munsi ya 1 × 4 birasabwa gukoresha ibice bya FBT, mugihe ibice bitandukanijwe hejuru ya 1 × 8 birasabwa kubice bya PLC.Kumurongo umwe cyangwa ibiri yoherejwe, FBT itandukanya irashobora rwose kuzigama amafaranga.Kumurongo mugari wa PON, gutandukanya PLC nihitamo ryiza urebye kwaguka no kugenzura ibikenewe.

Umwanzuro

Fibre optique itandukanya itanga ibimenyetso kuri fibre optique kugirango igabanwe hagati ya fibre ebyiri cyangwa nyinshi.Kubera ko ibice bitarimo ibikoresho bya elegitoroniki cyangwa bisaba imbaraga, ni ibintu bigize kandi bikoreshwa cyane mu miyoboro myinshi ya fibre optique.Rero, guhitamo fibre optique itandukanya kugirango ifashe kongera imikoreshereze myiza yibikorwa remezo ni urufunguzo rwo guteza imbere imiyoboro yububiko izaramba ejo hazaza.
