Izindaba

Ngo-April 23-26, 2024, Kexint iqhaza embukisweni eMoscow Comelink. I-Comelink iqhamuke njengenkampani entsha emakethe yaseRussia, ikakhulukazi ikhombisa imikhiqizo ye-OLT ONT kumakhasimende. I-Kexint isagxile ezintamboni ze-fiber optic kanye nemikhiqizo yesikhungo sedatha.

I-fiber optic splitter, esebenza njengedivayisi engasebenzi, ivumela ukuthi umsebe wokukhanya okufakwayo uhlukaniswe ube yimisebe emibili noma ngaphezulu. Ubuchwepheshe obubili obuyinhloko obusetshenziswa kuma-optical splitter yindlela ye-Fused Biconical Taper (FBT) kanye nendlela ye-Planar Lightwave Circuit (PLC). Ukwehluka okukhulu phakathi kwama-FBT nama-PLC splitter kungaba umthombo wokudideka. Lesi sihloko sizokwethula ukuhlaziywa okucacile, okuhlangene kwezici zawo eziyinhloko.

Ukuxhuma ngezintambo zethusi kuyindlela yokuxhumana esetshenziswa kakhulu ezindaweni zenethiwekhi zanamuhla. Lezi zintambo zisebenzisa ithusi elihambisa kakhulu njengomgogodla wazo, zisebenzisa isakhiwo sethusi esinezintambo eziningi noma esiqinile, futhi zigoqwe ngezinto zokuvikela ukuqinisekisa ukudluliselwa kahle kwezimpawu zikagesi. Ukuqhuba kahle kwethusi nokuqina kwayo sekuyisikhathi eside kuyenza ibe yinto ekhethwayo yokudlulisa izimpawu ezahlukene ze-analog nezedijithali. Emkhakheni wokuxhumana kwedatha, izintambo zethusi zidlala indima ebalulekile ekudluliseni izimpawu ze-Ethernet phakathi kwama-router, amaswishi, amaseva, amaphaneli e-patch, kanye nemishini ye-terminal. Ngokuvamile ingadlulisela izimpawu ngokuthembekile emabangeni angadluli amamitha ayi-100 futhi inikeza amazinga ahlukahlukene okusebenza, njenge-Cat5e, i-Cat6, kanye ne-Cat6a, ngayinye inikeza i-bandwidth ephezulu kanye nokuvikeleka okunamandla kokuphazamiseka. Nakuba izintambo ze-fiber optic ngokuvamile zihlotshaniswa nezinhlelo zokusebenza zebanga elide, i-bandwidth ephezulu, izintambo zethusi zihlala ziyingxenye ebalulekile yezintambo ezivundlile zenethiwekhi yendawo (i-LAN) ngenxa yokusebenza kahle kwezindleko, ukunqanyulwa kalula, kanye nokusekelwa kwe-Power over Ethernet (PoE).

Lesi sixhumi esibonakalayo esikwazi ukumelana namanzi sinesilinganiso sokuvikela se-IP67, esivumela izixhumi ezijwayelekile ze-fiber optic ukuthi zifakwe ngendlela enokwethenjelwa ezimeni zangaphandle, ezimanzi, noma ezinothuli. Isixhumi esibonakalayo saso sinikeza ukusebenza okuphakeme okungenamanzi, okuvumela ukukhwelana kalula nokunqanyulwa ngaphandle kwendawo ebiyelwe. Idizayini iphinde yenze ukuhlola kube lula, iqinisekise ukuthi amasheke awaphazamisi ukuhlanganiswa noma ukushintshwa kwezingxenye zangaphakathi, ngaleyo ndlela kuthuthukisa ukusingathwa kanye nokusebenza kahle kokunakekelwa.

Izintambo ze-fiber loopback zingase zibe zincane, kodwa indima yazo ekuxilongweni kwenethiwekhi nokusebenza kwesistimu inkulu. Ochwepheshe be-IT, abaphathi benethiwekhi, nonjiniyela bathembele kulawa mathuluzi alula kodwa asebenzayo ukuze ahlole, axazulule, futhi agcine amanethiwekhi e-fiber optic asebenza kahle kakhulu. Kodwa ziyini ngempela izintambo ze-fiber loopback, zisebenza kanjani, futhi kungani zibalulekile kungqalasizinda yenethiwekhi yanamuhla? Lo mhlahlandlela uzokuhlahlela konke.

1. Kuyini i-polarity? Kunoma yikuphi ukufakwa, kuyadingeka ukuqinisekisa ukuthi i-transmitter optical ekugcineni ixhunywe kumamukeli optical ngakolunye uhlangothi. Lokhu kuhambisana kwesignali edlulisiwe (Tx) kanye nedivayisi eyamukelayo (Rx) kuzo zombili iziphetho zesixhumanisi sefayibha kubizwa ngokuthi i-polarity. 2. Uhlolojikelele lwe-polarity Izinhlobo ezimbili zezixhumanisi zefayibha zivezwe kuzinga le-TIA: uxhumano lwesignali ye-serial duplex kanye noxhumano lwesignali efanayo. Lesi sihloko sidingida umthelela we-polarity kusignali ye-serial duplex kanye nesignali ehambisanayo.

Icala lokutholwa kwe-FTTH lihlala liqinile. Abathengi bayaqaphela ukuthi i-FTTH inikeza isevisi esheshayo, ethembekile ukuhlangabezana nezidingo ezikhulayo zomkhawulokudonsa. Amathuba e-FTTH angase alele ezindaweni ezingaminyana kancane, kodwa abahlinzeki kufanele baqaphele lapho bekhetha izimakethe zokunwetshwa. Amanani entengo asobala, ikhwalithi yesevisi kanye nokunqwabelana kwesevisi okungeziwe kungasebenza njengezahlukanisi eziyinhloko.

Ngokukhula okusheshayo kwe-cloud computing, Artificial Intelligence (AI), 5G, kanye Ne-Intanethi Yezinto (IoT), ithrafikhi yedatha yomhlaba wonke ikhula ngamandla. Njengengqalasizinda eyinhloko yenkathi yedijithali, izikhungo zedatha manje zidinga ubuchwepheshe bokuxhumana obubonakalayo obunikeza isivinini esiphezulu, ukuminyana okukhulu, nokubambezeleka okuphansi. Ngokumelene nalokhu kwangemuva, i-1.6T OSFP-XD optical module iye yavela njengomkhiqizo omele wokuxhumana optical wesizukulwane esilandelayo.

I-26th China International Optoelectronic Exposition (CIOE) yenzeka ngo-September 10–12, 2025, e-Shenzhen World Exhibition and Convention Centre, eduze noMbukiso Wamazwe Ngamazwe We-Semiconductor & IC Industry Innovation Expo 2025 (SEMI-e). I-CIOE, ethathwa njengophawu lomhlaba jikelele embonini ye-optoelectronics, iletha izinkampani ezingaphezu kuka-3,800 emhlabeni wonke. Ibonisa imikhakha eyinhloko ye-span efaka ukuxhumana okubonakalayo, ukunemba optics, amalaser, nokukhiqiza okuhlakaniphile, i-AR/VR, izinzwa ezihlakaniphile, izibonisi ezithuthukisiwe, nokusungulwa kwezithombe ezintsha. Umcimbi uhlanganisa uchungechunge oluphelele lokuhlinzeka, kusukela ezintweni eziyisisekelo kanye nemishini ebalulekile kuya ezixazululweni zezinga lesistimu.

Isixhumi se-fiber esingathintana naye (NC) isixhumi esilandelayo se-fiber optical , lapho kungekho ukuxhumana phakathi kwezindawo zefayibha. Kunezici ezimbili ezibalulekile kusixhumi se-NC, 1) indawo yefayibha ihlehlisiwe, 2) i-fiber surface ine-anti-reflection coating. Inikeza ukusebenza kwe-optical okuthuthukisiwe kakhulu nokuphila isikhathi eside. Ngoba i-fiber surface ihlehlisiwe futhi ungaxhumani nendawo yokukhwelana.

Intambo yesichibi se-MPO elandelekayo ikhebula le-fiber optic elinabantu abaningi elifaka ukukhanya kwe-LED eyakhelwe ngaphakathi ekugcineni ngakunye, okuvumela ochwepheshe ukuthi bakhombe kalula futhi balandele umkhondo wezintambo ezingazodwana ezindaweni eziminyene njengezikhungo zedatha. Lokhu kuqeda isidingo sokunqamula izintambo eziningi ukuze kutholwe elungile, kuvimbele ukunqanyulwa kwephutha kanye nokonga isikhathi nomsebenzi.

Izixhumi ze-fiber ze-LC, ezimi njengetshe legumbi lokuxhumeka kwe-fiber optic ephezulu-density, sezibaluleke kakhulu kumanethiwekhi esimanje ezokuxhumana kanye nekhebula yesikhungo sedatha. Uzothola ukuthi i-LC ecosystem ihlanganisa izinhlobonhlobo zezingxenye, ezihlanganisa kodwa ezingakhawulelwe kuzixhumi ze-LC duplex nezixhumi zemodi eyodwa, i-LC uniboot fibre jumpers, i-LC unibody patch cords, i-LC uniboot push pull jump jumpers, ama-adaptha e-LC polarized, amakhasethi e-LC fibre, namahhanisi ahlukahlukene enziwe ngokwezifiso e-LC fibre. Ngakho-ke, ububanzi bezixazululo ezisekelwe ku-LC kuzinhlelo zokusebenza zomhlaba wonke ze-fiber optic? Lesi sihloko sidingida esizindeni esinwetshiwe semikhiqizo ehlanganiswe i-LC kanye nokusetshenziswa kwayo okuthuthukayo.
