Amamojula okukhanya angamadivayisi e-optoelectronic enza ukuguqulwa kwe-photoelectric kanye ne-electro-optical.Ukuphela kokudlulisa kwe-optical module kuguqula isignali kagesi ibe isignali ye-optical, futhi ukuphela kokwamukela kuguqula isignali ye-optical ibe isignali kagesi.I-Feiyu Fiber yethula ukusetshenziswa kwamamojula optical ezimbonini ezahlukahlukene.Izinkambu zesicelo eziyinhloko zamamojula optical zihlanganisa: 1. Isikhungo sedatha;2. Isiteshi sokuxhumana ngomakhalekhukhwini;3. Uhlelo lokuhlukanisa amaza amaza;4. Inethiwekhi ye-SAN/NAS yokugcina;5. Inethiwekhi yabathwali be-5G.
1. Isikhungo sedatha.
Isikhungo sedatha samanje asiselona igumbi lekhompiyutha elilodwa noma amaningana, kodwa iqembu lamaqoqo esikhungo sedatha.Ukuze uthole umsebenzi ojwayelekile wezinsizakalo ze-inthanethi ezahlukahlukene nezimakethe zohlelo lokusebenza, izikhungo zedatha zidingeka ukuthi zisebenze ngokubambisana.Ukushintshana kwedatha yesikhathi sangempela phakathi kwezikhungo zedatha kudale isidingo samanethiwekhi okuxhumana esikhungo sedatha, futhi ukuxhumana kwe-fiber optical sekuyindlela edingekayo yokufinyelela ukuxhumana.
Ihlukile kumishini yokudlulisa yenethiwekhi yokufinyelela kocingo evamile, ukuxhunywa kwesikhungo sedatha kudinga isivinini esiphezulu, ukusetshenziswa kwamandla okuphansi, kanye nokwenza kancane kancane kwezinto zokusebenza zokushintsha ukuze kuzuzwe ukudluliswa kolwazi okukhudlwana nokunamandla.Isici esiyinhloko esinquma ukuthi lokhu kudlalwa kungenziwa yini imojula yokubona.
Amamojula we-optical wesikhungo sedatha angahlukaniswa ngezigaba ezintathu ngokuya ngohlobo lokuxhuma:
(1) Kusukela esikhungweni sedatha kuye kumsebenzisi, ikhiqizwa ukuziphatha komsebenzisi wokugcina njengokufinyelela efwini ukuze uphequlule iwebhu, ukuthumela nokwamukela ama-imeyili, nokusakazwa kwevidiyo;
(2) Ukuxhumana kwesikhungo sedatha, okusetshenziselwa ikakhulukazi ukuphindaphinda idatha, ukuthuthukiswa kwesofthiwe kanye nesistimu;
(3) Ngaphakathi kwesikhungo sedatha, ngokuyinhloko isetshenziselwa ukugcinwa kolwazi, ukukhiqiza kanye nezimayini.Ngokwesibikezelo se-Cisco, ukuxhumana kwangaphakathi kwesikhungo sedatha kubala ngaphezu kwe-70% yokuxhumana kwesikhungo sedatha.Ukuthuthukiswa okukhulu kokwakhiwa kwesikhungo sedatha nakho kuye kwazala ukuthuthukiswa kwamamojula we-high-speed optical.
2. Iziteshi eziyisisekelo zokuxhumana ngomakhalekhukhwini.
Isiteshi sokuxhumana esingumahambanendlwana sisho isiteshi somsakazo esidlulisa ulwazi phakathi kwesikhungo sokushintshwa komakhalekhukhwini kanye netheminali yomakhalekhukhwini endaweni ethile yomsakazo.
Isiteshi sesisekelo sokuxhumana kwamaselula sika-opharetha sidinga namamojula okubona ukuze sibone ukuxhumana phakathi kwamadivayisi.Isiteshi esiyisisekelo sinamadivayisi we-RRU kanye ne-BBU.Kuhlelo lokusebenza, sidinga ukuxhuma izixhumanisi phakathi kwalawa madivayisi amabili, okudinga amamojula ethu okubona.Kunethiwekhi ye-4G, imishini esetshenziselwa ukuxhuma i-BBU ne-RRU ngokuyinhloko i-1.25G module optical, 2.5G module optical, 6G module optical, 10G module optical, njll.
3. Uhlelo lwe-Passive WDM
Phakathi kwezixazululo zobuchwepheshe ezamukelwe ku-5G fronthaul, i-WDM engenzi lutho ngokungangabazeki ilandisa ngenani eliphakeme kakhulu.Uhlelo lwe-Passive WDM luqukethe imodyuli ye-optical color, i-multiplexer ne-fiber optical.
Umgomo oyinhloko wobuchwepheshe bokuhlukaniswa kwe-wavelength engenzi lutho ukusebenzisa ubuchwepheshe be-WDM ukuhlanganisa amasignali optical anamaza ahlukene ahlukene futhi uphathe uchungechunge lolwazi lube yinqwaba eyodwa, futhi uludlulisele ku-fiber optical eyodwa ukuze ubone ukudluliswa phakathi kwezinsizakalo.I-WDM ingadlulisela kanyekanye amasiginali amaningi ngefayibha eyodwa yokubona.Ingakwazi ukudlulisa isignali ngayinye ngobude obuthile bokukhanya obufana nesignali, futhi amasignali okubona amaza ahlukene angahlukaniswa ekugcineni kokwamukela.Isistimu yokuhlukanisa i-wavelength ngokuyinhloko isistimu eyakhiwe izingxenye ezimbili: imojuli yokukhanya kombala ne-OTM.
4. Inethiwekhi yesitoreji ye-SAN/NAS.
Ngokuthuthuka okusheshayo kwe-inthanethi nezinhlelo zokusebenza zenethiwekhi, izinhlobo zedatha okufanele zicutshungulwe uhlelo lokugcinwa kolwazi lwedatha nazo zanda kakhulu, okwenza uhlelo lokugcinwa kolwazi lwedatha lubhekane nezinselele ezingakaze zibonwe ngaphambili.Imishini eyengeziwe yokugcina inethiwekhi (I-Network Attached Storage, efushanisiwe njenge-NAS) kanye namanethiwekhi okugcina esifunda (Inethiwekhi Yendawo Yesitoreji, efushaniswe ngokuthi i-SAN), angahlukanisa idivayisi yokugcina imininingwane yedatha kunethiwekhi kanye nohlelo lokusingatha, kokubili ukuphathwa okumaphakathi kwedatha yolwazi, futhi Ngokuhlakazeka okuhle, inikeza isisombululo esisebenza kahle kakhulu sokubona ukuphathwa kwedatha okumaphakathi.
Umsebenzi oyinhloko wenethiwekhi ye-SAN/NAS yokugcina idatha.Phakathi kwazo, inethiwekhi ye-SAN ngokuyinhloko yakhiwe amaseva, ukushintshwa kwesiteshi se-fiber, amadivaysi okugcina, nabathwali bokudlulisela (amamojula optical, ama-fiber jumpers);inethiwekhi yesitoreji se-NAS ikakhulukazi yakhiwe isitoreji se-NAS, amaswishi, Akhiwe imishini yokugcina (ikhompyutha), isithwali sokudlulisa (imojula ye-optical, i-optical fiber jumper).
Kufanele kuqashelwe ukuthi inethiwekhi ye-SAN isebenzisa amamojula e-Fiber Channel optical futhi idinga ukusekela iphrothokholi ye-FC Fiber Channel, kuyilapho amamojula optical asetshenziswa kunethiwekhi yesitoreji se-NAS adinga kuphela ukuhambisana nephrothokholi ye-Ethernet.
5. Inethiwekhi yabathwali be-5G.
Inethiwekhi ye-5G ihlukaniswe izingxenye ezintathu, okuyinethiwekhi yokufinyelela, inethiwekhi yabathwali kanye nenethiwekhi eyinhloko.Ukuze uqonde ubudlelwano phakathi kwabo, ungabheka isithombe esilandelayo:
Inethiwekhi yabathwali be-5G ngokuvamile ihlukaniswa ibe isendlalelo sokufinyelela kwedolobha elikhulu, isendlalelo sokuhlanganisa sedolobha elikhulu, kanye nesendlalelo esiyinhloko sedolobhakazi/umugqa wesifunda ukuze kufezeke imisebenzi ye-fronthaul kanye ne-midhaul yezinsizakalo ze-5G.
Izimo zohlelo lokusebenza ezijwayelekile ze-5G fronthaul zifaka ukuxhumana okuqondile kwefayibha, i-WDM engenzi lutho kanye ne-WDM esebenzayo, njll.
Izidingo ezijwayelekile zamamojula we-optical ku-5G fronthaul application zimo zimi kanje:
① Hlangana nezinga lokushisa lezinga lezimboni, izidingo zokuthembeka okuphezulu: Uma kucatshangelwa indawo yokusebenza yangaphandle, imojula ye-fronthaul optical kumele ihlangabezane nezinga lokushisa lezimboni elingu -40℃~+85℃, futhi idinga ukuhlangabezana nezidingo zokuvikela uthuli.
②Izindleko eziphansi: Isidingo samamojula we-5G optical sidlula kakhulu leso se-4G, ikakhulukazi kumamojula we-fronthaul optical.Izindleko eziphansi zingenye yezidingo eziyinhloko zamamojula optical embonini ye-5G.I-5G medium kanye ne-backhaul ihlanganisa isendlalelo sokufinyelela, isendlalelo sokuhlanganisa kanye nesendlalelo esiyinhloko sendawo yedolobha elikhulu.Amamojula adingekayo we-optical awafani kakhulu nobuchwepheshe bemojula ye-optical esetshenziswa esikhungweni samanje sedatha.Isendlalelo sokufinyelela sizosebenzisa ikakhulukazi i-25Gb/s, 50Gb/s, 100Gb/s Ukuze uthole amamojula optical of s namanye amanani, amamojula optical e-DWDM anamazinga we-100Gb/s, 200Gb/s, kanye no-400Gb/s azosetshenziswa kakhulu ungqimba wokuhlanganisa nangaphezulu.
Ekugcineni, kufanele kushiwo ukuthi isidingo sokukhula samamojula optical sincike kakhulu emakethe yezokuxhumana yedatha kanye nemakethe ye-telecom.Kule minyaka yedatha yanamuhla, amamojula okubona kufanele angenise amathuba amasha okuthuthukisa.
I-Huanet inganikeza zonke izinhlobo zamamojula optical, wamukelekile ukuxhumana nezintengo.
