Iimodyuli ze-Optical zixhobo ze-optoelectronic ezenza i-photoelectric kunye ne-electro-optical conversion.Isiphelo sokudlulisa imodyuli ye-optical iguqula isignali yombane ibe yisignali ye-optical, kwaye isiphelo sokufumana siguqula isignali ye-optical ibe ngumqondiso wombane.I-Feiyu Fiber ibonisa ukusetyenziswa kweemodyuli ze-optical kumashishini ahlukeneyo.Iinkalo zesicelo eziphambili zeemodyuli ze-optical ziquka: 1. Iziko ledatha;2. Isikhululo sonxibelelwano oluphathwayo;3. Inkqubo yokwahlulwa kobude obungasiyo;4. SAN/NAS inethiwekhi yokugcina;5. Inethiwekhi yomthwali we-5G.
1. Iziko ledatha.
Iziko ledatha langoku alisekho elinye okanye amagumbi amaninzi ekhompyutheni, kodwa iqela lamaqela amaziko edatha.Ukuze uqonde umsebenzi oqhelekileyo weenkonzo ezahlukeneyo ze-Intanethi kunye neemarike zesicelo, amaziko edatha afunekayo ukuba asebenze ngokubambisana.Utshintshiselwano lwangempela lwexesha lobuninzi bolwazi phakathi kwamaziko edatha luye lwadala imfuno yonxibelelwano lweziko ledatha, kwaye unxibelelwano lwe-fiber optical luye lwaba yindlela efunekayo yokufikelela kwi-interconnection.
Ukwahluke kwisixhobo sothumelo lwe-telecom yemveli yokufikelela kwinethiwekhi, ukudityaniswa kweziko ledatha kufuna isantya esiphezulu, ukusetyenziswa kwamandla aphantsi, kunye ne-miniaturization engaphezulu yezixhobo zokutshintsha ukuphumeza ukuhanjiswa kolwazi olukhulu kunye nolunzulu.Into ephambili emisela ukuba le midlalo inokufezekiswa yimodyuli ye-optical.
Iimodyuli zonxibelelwano lweziko ledatha zinokwahlulwa ngokweendidi ezintathu ngokohlobo lonxibelelwano:
(1) Ukusuka kwiziko ledatha ukuya kumsebenzisi, iveliswa kukuziphatha komsebenzisi wokugqibela njengokufikelela kwilifu ukukhangela iwebhu, ukuthumela nokufumana ii-imeyile, kunye nemijelo yevidiyo;
(2) Uqhagamshelwano lweziko ledatha, ikakhulu esetyenziselwa ukuphindaphinda idatha, isoftware kunye nokuphuculwa kwenkqubo;
(3) Ngaphakathi kwiziko ledatha, isetyenziselwa ikakhulu ukugcina ulwazi, ukuveliswa kunye nokumbiwa kwemigodi.Ngokutsho kweCisco yokubikezela, unxibelelwano lwangaphakathi lweziko ledatha libalelwa ngaphezu kwe-70% yonxibelelwano lweziko ledatha.Uphuhliso olukhulu lokwakhiwa kwamaziko edatha luye lwazala ukuphuhliswa kweemodyuli ze-high-speed optical.
2. Izikhululo ezisisiseko zonxibelelwano oluphathwayo.
Isikhululo sonxibelelwano esiphathwayo sibhekisa kwisikhululo sikanomathotholo esihambisa ulwazi phakathi kweziko lonxibelelwano oluphathwayo kunye netheminali yefowuni ephathwayo kwindawo ethile yosasazo lukanomathotholo.
Isikhululo sesiseko sonxibelelwano esiphathwayo sikwafuna iimodyuli ze-optical ukuqonda uqhagamshelwano phakathi kwezixhobo.Isikhululo esisisiseko sinezixhobo ze-RRU kunye ne-BBU.Kwisicelo, kufuneka sidibanise amakhonkco phakathi kwezi zixhobo zimbini, ezifuna iimodyuli zethu ze-optical.Kwinethiwekhi ye-4G, izixhobo ezisetyenziselwa ukudibanisa i-BBU kunye ne-RRU ikakhulu imodyuli ye-1.25G ye-optical, i-2.5G imodyuli ye-optical, i-module ye-6G ye-optical, i-module ye-10G ye-optical, njl.
3. Inkqubo ye-WDM ye-Passive
Phakathi kwezisombululo zobuchwepheshe ezamkelwe kwi-5G fronthaul, i-WDM engabonakaliyo ngokungathandabuzekiyo ibala umlinganiselo ophezulu.Inkqubo ye-Passive WDM iqukethe imodyuli ye-optical color, i-multiplexer kunye ne-fiber optical.
Umgaqo ongundoqo wetekhnoloji yolwahlulo lwe-wavelength kukusebenzisa itekhnoloji ye-WDM ukudibanisa imiqondiso ye-optical kunye ne-wavelengths eyahlukeneyo kunye nokuthwala uluhlu lolwazi kwi-bundle enye, kwaye idluliselwe kwi-fiber optical enye ukuqonda ukuhanjiswa phakathi kweenkonzo.I-WDM inokuhambisa ngaxeshanye imiqondiso emininzi ecaleni kwefiber enye ye-optical.Iyakwazi ukuhambisa umqondiso ngamnye kunye nobude obuthile bokukhanya obuhambelana nomqondiso, kwaye izibonakaliso ze-optical zamanqanaba ahlukeneyo anokwahlulwa ekupheleni kokufumana.Inkqubo yolwahlulo lwamaza okwenziwa ikakhulu yinkqubo eyenziwe ngamacandelo amabini: imodyuli yokukhanya kombala kunye ne-OTM.
4. SAN/NAS inethiwekhi yokugcina.
Ngophuhliso olukhawulezayo lwe-Intanethi kunye nezicelo zenethiwekhi, iintlobo zedatha eziza kucutshungulwa yinkqubo yogcino lwedatha nazo ziyanda kakhulu, nto leyo eyenza inkqubo yokugcina ulwazi lwedatha ijongane nemingeni engazange ibonwe ngaphambili.Izixhobo zokugcinwa kwenethiwekhi ezongezelelweyo (I-Network Attached Storage, efinyeziweyo njenge-NAS) kunye nothungelwano lokugcinwa kwengingqi (Inethiwekhi yendawo yokuGcina, ifinyeziwe njenge-SAN), inokwahlula isixhobo sokugcina ulwazi lwedatha kwinethiwekhi kunye nenkqubo yokusingatha, zombini ulawulo oluphakathi lwedatha yolwazi, kunye Nokulinganisa okulungileyo, inika esona sisombululo sisebenzayo sokuqonda ulawulo lwedatha olusembindini.
Umsebenzi ophambili we-SAN/NAS yokugcina inethiwekhi kukugcina idatha.Phakathi kwabo, inethiwekhi ye-SAN iqulethwe ngokukodwa ngamaseva, i-fiber channel switches, izixhobo zokugcina, kunye nabathwali bokuhambisa (iimodyuli ze-optical, i-fiber jumpers);inethiwekhi yokugcina ye-NAS iqulunqwe ikakhulu kukugcinwa kwe-NAS, ukutshintsha, Ukuqulunqwa kwezixhobo zokugcina (ikhompyutheni), i-carrier carrier (imodyuli ye-optical, i-optical fiber jumper).
Kufuneka kuqatshelwe ukuba inethiwekhi ye-SAN isebenzisa iimodyuli ze-Fiber Channel optical kwaye idinga ukuxhasa i-protocol ye-FC Fiber Channel, ngelixa iimodyuli ze-optical ezisetyenziswe kwinethiwekhi yokugcina i-NAS zifuna kuphela ukuhambelana ne-Ethernet protocol.
5. Inethiwekhi yomthwali we-5G.
Inethiwekhi ye-5G ihlulwe ibe ngamacandelo amathathu, oko kukuthi inethiwekhi yokufikelela, inethiwekhi yomthwali kunye nenethiwekhi engundoqo.Ukuqonda ubudlelwane phakathi kwabo, ungabhekisa kulo mfanekiso ulandelayo:
Inethiwekhi ye-5G ye-bearer ihlukaniswe ngokubanzi kwi-metropolitan access layer, i-metropolitan aggregation layer, kunye ne-metropolitan core layer / provincial trunk line ukuqonda imisebenzi ye-fronthaul kunye ne-midhaul yeenkonzo ze-5G.
Iimeko zesicelo eziqhelekileyo ze-5G fronthaul ziquka uxhulumaniso lwefiber ngqo, i-WDM engabonakaliyo kunye ne-WDM esebenzayo, njl.
Iimfuno eziqhelekileyo kwiimodyuli ze-optical kwi-5G ye-fronthaul ye-fronthaul ye-cecenarios zilandelayo:
①Dibana nobushushu bebakala loshishino, iimfuno ezithembekileyo eziphezulu: Ukuqwalasela indawo yokusebenza yangaphandle, imodyuli yangaphambili ye-optical module kufuneka ihlangabezane noluhlu lwamaqondo obushushu amashishini -40℃~+85℃, kwaye kufuneka ihlangabezane neemfuno zothuli.
②Ixabiso eliphantsi: Imfuno yeemodyuli ze-5G ze-optical zidlula kakhulu kwi-4G, ngokukodwa kwiimodyuli ze-fronthaul optical.Iindleko eziphantsi ngenye yeemfuno eziphambili zeemodyuli ze-optical kwishishini le-5G.I-5G ephakathi kunye ne-backhaul ihlanganisa i-access layer, i-aggregation layer kunye ne-core layer ye-metropolitan area.Iimodyuli ze-optical ezifunekayo azifani kakhulu nobuchwepheshe bemodyuli ye-optical esetyenziswe kwiziko ledatha yangoku.Uluhlu lokufikelela luya kusebenzisa kakhulu i-25Gb / s, 50Gb / s, 100Gb / s Kwiimodyuli ze-optical ze-s kunye nezinye iireyithi, iimodyuli ze-DWDM optical kunye namazinga e-100Gb / s, i-200Gb / s, kunye ne-400Gb / s iya kusetyenziswa kakhulu umaleko wokudityaniswa nangaphezulu.
Okokugqibela, kufuneka kuthiwe imfuno yokukhula yeemodyuli zamehlo ikakhulu ixhomekeke kwimarike yonxibelelwano lwedatha kunye nentengiso ye-telecom.Kwixesha lanamhlanje ledatha, iimodyuli zamehlo zibophelelekile ukuba zingenise amathuba amatsha ophuhliso.
I-Huanet inokubonelela zonke iintlobo zeemodyuli ze-optical, wamkelekile ukuba uqhagamshelane namaxabiso.
