Ibhizinisi lobuchwepheshe obuphezulu eligxile ocwaningweni nasekuthuthukisweni kwezokuxhumana kanye nokukhiqizwa kwefiber optical.
Isixhumi se-MTP®/MPO simele intuthuko enkulu ekuxhumekeni kwe-multi-fiber optic, ukuletha ukusebenza okuphakeme kokubona nokusetshenziswa kwemishini. Idizayini yayo enobunjiniyela obunembayo (bona isithombe esingezansi) iqinisekisa ukuphathwa okuthembekile kwe-fiber polarity kuwo wonke amasistimu wenethiwekhi ye-MTP®/MPO.
Ngakho-ke, iyini ngempela i-fiber polarity? Isixhumanisi esijwayelekile se-duplex fibre optic sidinga imicu emibili ukuze kusungulwe ukuxhumana okuphelele—owokudlulisela (Tx) nowokwamukela (Rx). I-polarity efanele iqinisekisa ukuthi isidluliseli ekugcineni sixhuma kumamukeli ngakolunye uhlangothi, sigcine ukugeleza kwesignali okulungile kusixhumanisi. Lokhu kufanisa kwe-Tx ne-Rx kuzo zombili iziphetho yikho okuchaza i-fiber polarity, elawula indlela eqondisayo yamasignali optical.
Nakuba izixhumi ezivamile ze-simplex ezifana ne-LC noma i-SC zingaphendulwa kalula noma zibekwe kabusha ukuze kuzuzwe i-polarity elungile, izinhlelo ze-MTP®/MPO ezinqanyulwe ngaphambili—ezinezikhundla eziningi zefiber engaguquki—zidinga ukuphathwa kwe-polarity ngamabomu nokuhlelekile kusukela ekuqaleni.
Izinhlobo Zekhebula Ezintathu Zezindlela Ezintathu Ze-Polarity
Izinga le-TIA-568 lichaza izindlela ezintathu ezaziwayo ze-polarity—Indlela A, B, kanye no-C—ngayinye isetshenziswa kusetshenziswa umklamo ohambelanayo wekhebula lesiqu se-MTP®: Uhlobo A, Uhlobo B, Nohlobo C. Ngezansi sicacisa umehluko phakathi kwalezi zinhlobo zamakhebula, siqale ngokubuka kabanzi kokwakhiwa kwazo okungokomzimba ngaphambi kokunikeza imininingwane yokusetshenziswa kwazo endleleni ngayinye yokuxhuma.
I-MTP® Trunk Cable Type A
Futhi okubizwa ngokuthi ikhebula eliqondile, Uhlobo A lufaka isixhumi sokhiye ohlangothini olulodwa kanye nesixhumi sikakhiye phansi ekugcineni okuphambene. Lokhu kumisa kuphumela ekumeni kwefayibha efanayo emikhawulweni yomibili; isibonelo, i-fiber engena ku-Position 1 (P1) ngakolunye uhlangothi iphuma ku-P1 kolunye. Ukulandelana kwefayibha kwentambo ye-12-fiber Type A MTP® kuboniswa ngezansi:
I-MTP® Trunk Cable Type B
Ikhebuli yohlobo B, evame ukubizwa ngekhebula le-polarity ehlehlisiwe, ihlanganisa izixhumi zokhiye kuzo zombili iziphetho. Lokhu kuhlotshaniswa kwesixhumi esilinganayo kukhiqiza ukuguquguquka kwesimo sefayibha phakathi kweziphetho ezimbili—ifayibha ingena kuNdawo 1 (P1) endaweni yokuphuma eyodwa ku-Position 12 (P12) ngakolunye uhlangothi. Ukulandelana kwefayibha yekhebula ye-12-fiber Type B kuboniswa kumdwebo olandelayo:
I-MTP® Trunk Cable Type C
Ikhebuli yohlobo C, ngokuvamile eyaziwa ngokuthi ikhebula eliphendulwe ngamabili, ihlanganisa isixhumi sikakhiye-up ngakolunye uhlangothi nesixhumi sikakhiye-phansi ngakolunye—olufana nokubukeka komzimba noHlobo A. Isici sayo esihlukile, nokho, sisekushintsheni kwepheya ngayinye eseduze yefayibha phakathi kwamaphethelo. Isibonelo, i-fiber e-Position 1 (P1) ekugcineni ixhuma ku-Position 2 (P2) ngakolunye uhlangothi, kuyilapho i-fiber e-P2 ixhuma ku-P1. Lokhu kuphetshwa ngakubili kuyaqhubeka kuzo zonke izindawo zefiber. Ukulandelana kwefayibha yekhebula ye-12-fiber Type C kuboniswa kumdwebo olandelayo:
Izindlela Ezintathu Zokusebenzisa I-polarity
Indlela ngayinye ye-polarity (A, B, kanye no-C) isebenzisa uhlobo oluhambisanayo lwekhebula lesiqu se-MTP®. Ukuze uqedele i-end-to-end fibre duplex circuit, zontathu izindlela zidinga izintambo zokuchibiyela eziphindwe kabili kuzo zombili iziphetho. Izinga le-TIA licacisa okubili okuhlukile kwalezi zintambo zokuchibiyela eziyiduplex—imvamisa enqanyulwa ngezixhumi ze-LC noma ze-SC: uhlobo lwe-A-to-A (inguqulo ephambanayo) kanye nohlobo luka-A-to-B (inguqulo eqondile).
Isigaba esilandelayo sibonisa ukuthi izingxenye ezihlukahlukene ngaphakathi kwesistimu ye-MTP® zihlanganiswa kanjani ukuze kuzuzwe uxhumano lwe-polarity oluthobela amazinga, njengoba kuchazwe i-TIA.
Indlela A:
Indlela A yokuxhumana ikhonjisiwe kumdwebo ongezansi. Le ndlela isebenzisa intambo yohlobo A ye-trunk ukuxhuma imojuli ye-MTP® ekugcineni kwesiteshi. Izintambo ezijwayelekile ze-A-to-B (eziqondile-ngokudlulele) zokuchibiyela eziphindwe kabili zisetshenziswa nhlangothi zombili ukuze kuqedelwe ukuxhumana.
Indlela B:
Nge-Polarity Method B, ikhebuli yesiqu sohlobo B isungula ukuxhumana phakathi kwamamojula amabili e-MTP® ekugcineni kwesixhumanisi. Njengoba kushiwo ngaphambili, izintambo zohlobo B zihlehlisa indawo yefayibha ukusuka komunye umkhawulo kuya komunye. Ukuze kunxeshezelwe lokhu kuguqulwa nokuqinisekisa ukugeleza kwesignali okulungile ekupheleni ukuya ekupheleni, izintambo ezijwayelekile zokuhlanganisa i-A-to-B (eziqondile-udlule) zisetshenziswa nhlangothi zombili.
Indlela C:
I-Polarity Method C isebenzisa intambo yesiqu yohlobo C (ephendulwe ngamabili) ukuze ixhume amamojula we-MTP® kuzo zombili iziphetho zesixhumanisi. Kusetshenziswa izintambo ezijwayelekile ze-A-to-B duplex patch ohlangothini ngalunye ukuze kuqedelwe isiteshi.
