Optical modules maoptoelectronic madivayiri anoita photoelectric uye electro-optical kutendeuka.Mhedziso yekutumira ye optical module inoshandura chiratidzo chemagetsi muchiratidzo chemaziso, uye kuguma kwekugamuchira kunoshandura chiratidzo chemaziso muchiratidzo chemagetsi.Feiyu Fiber inopa mashandisirwo eOptical modules mumaindasitiri akasiyana.Iyo mikuru yekushandisa minda ye optical modules inosanganisira: 1. Data center;2. Mobile communication base station;3. Passive wavelength division system;4. SAN/NAS kuchengetedza network;5. 5G mutakuri network.
1. Data centre.
Ikozvino data data haisisiri imwe chete kana akati wandei makamuri emakomputa, asi boka re data data masumbu.Kuti uone basa rakajairwa reakasiyana masevhisi eInternet uye misika yekushandisa, nzvimbo dzedata dzinodiwa kuti dzishande mukurongeka.Iyo chaiyo-nguva misa yekutsinhana yeruzivo pakati penzvimbo dzedata yakagadzira kudiwa kwedata center interconnection network, uye optical fiber kutaurirana yave nzira inodiwa yekuwana kubatanidza.
Yakasiyana neyechinyakare telecom yekuwana network yekufambisa michina, data centre yekubatanidza inoda kukurumidza kukurumidza, kuderera kwesimba rekushandisa, uye yakawanda miniaturization yekuchinja midziyo kuti uwane yakakura uye yakanyanya kufambisa yeruzivo.Chinhu chakakosha chinotarisisa kana kuita uku kuchigona kuitika ndeye optical module.
Data center communication optical modules inogona kukamurwa muzvikamu zvitatu zvinoenderana nerudzi rwekubatanidza:
(1) Kubva panzvimbo yedata kusvika kumushandisi, inogadzirwa nemagumo-emushandisi maitiro akadai sekuwana gore kuti uongorore webhu, kutumira uye kugamuchira maemail, uye vhidhiyo hova;
(2) Data center interconnection, inonyanya kushandiswa kudzokorora data, software uye system upgrades;
(3) Mukati me data data, inonyanya kushandiswa kuchengetedza ruzivo, chizvarwa uye migodhi.Maererano nekufanotaura kwaCisco, kutaurirana kwemukati kwe data data kunodarika 70% yekukurukurirana kwe data data.Iko kukura kukuru kwekuvakwa kwedata data kwakaberekawo kugadzirwa kwe-high-speed optical modules.
2. Nharembozha yekutaurirana base zviteshi.
Nhepfenyuro yenharembozha (mobile communication base station) inoreva nhepfenyuro yeredhiyo inofambisa ruzivo pakati penzvimbo inochinja nharembozha nechiteshi chenharembozha mune imwe nzvimbo yeredhiyo.
Iyo opareta's mobile communication base station inodawo optical modules kuona kubatana pakati pemidziyo.Iyo base station ine RRU uye BBU zvishandiso.Mukushandisa, tinoda kubatanidza zvinongedzo pakati pezviviri izvi, izvo zvinoda edu optical modules.Mune 4G network, midziyo inoshandiswa kubatanidza BBU neRRU inonyanya 1.25G optical module, 2.5G optical module, 6G optical module, 10G optical module, nezvimwewo.
3. Passive WDM system
Pakati pemhinduro dzehunyanzvi dzakagamuchirwa mu5G fronthaul, passive WDM pasina mubvunzo inoverengera chikamu chepamusoro.Passive WDM system ine color optical module, multiplexer uye optical fiber.
Musimboti wemusimboti we passive wavelength division tekinoroji ndeye kushandisa WDM tekinoroji kubatanidza masaini masaini ane akasiyana wavelengths uye kutakura nhevedzano yeruzivo mune rimwe bundle, uye kuaendesa mune imwe optical fiber kuona kutapurirana pakati pemasevhisi.WDM inogona panguva imwe chete kufambisa masaini akawanda pamwe chete neoptical fiber.Inogona kuendesa chiratidzo chega chega nehumwe urefu hwechiedza hunoenderana nechiratidzo, uye masaini emaziso emawavelengths akasiyana anogona kupatsanurwa pamagumo ekugamuchira.Iyo passive wavelength division system inonyanya kuve system inoumbwa nezvikamu zviviri: color light module uye OTM.
4. SAN/NAS kuchengetedza network.
Nekukurumidza kusimudzira kweInternet uye mashandisirwo etiweki, mhando dze data dzinofanirwa kugadziriswa neiyo data data system system iri kuwedzera zvakanyanya, izvo zvinoita kuti iyo data data system yekuchengetedza isangane nematambudziko asina kumboitika.Zvimwe zvekuchengetedza network (Network Attached Storage, yakapfupikiswa seNAS) uye nzvimbo dzekuchengetera nharaunda (Storage Area Network, yakapfupikiswa seSAN), vanogona kupatsanura ruzivo rwekuchengetedza ruzivo kubva kunetiweki uye iyo host system, zvese zviri pakati pekutonga kwedata data, uye Ne scalability yakanaka, inopa mhinduro inoshanda kwazvo yekuona centralized data management.
Basa guru reSAN/NAS yekuchengetedza network kuchengetedza data.Pakati pavo, iyo SAN network inonyanya kuumbwa nemaseva, fiber channel switches, zvigadziridzo zvekuchengetedza, uye kutakura vatakuri (optical modules, fiber jumpers);iyo NAS yekuchengetedza network inonyanya kuumbwa neNAS kuchengetedza, switch, Inoumbwa neinomira midziyo (kombuta), transmission carrier (optical module, optical fiber jumper).
Zvinofanira kuonekwa kuti SAN network inoshandisa Fiber Channel optical modules uye inoda kutsigira FC Fiber Channel protocol, nepo optical modules inoshandiswa muNAS yekuchengetedza network inongoda kuenderana neEthernet protocol.
5. 5G mutakuri network.
Iyo 5G network yakakamurwa kuita zvikamu zvitatu, zvinoti network yekuwana, mutakuri network uye core network.Kuti unzwisise hukama huri pakati pavo, unogona kutarisa kumufananidzo unotevera:
Iyo 5G inotakura network inowanzo patsanurwa kuita metropolitan yekupinda layer, metropolitan aggregation layer, uye metropolitan musimboti layer/province trunk line kuona kumberi uye midhaul mabasa e5G masevhisi.
Mamiriro ekushandisa e5G fronthaul anosanganisira yakananga fiber connection, passive WDM uye inoshanda WDM, nezvimwe.
Zvinodiwa zvinodikanwa zve optical modules mu5G fronthaul application scenarios ndeaya anotevera:
① Sangana nekupisa kwegiredhi remaindasitiri, kuvimbika kwakanyanya zvinodiwa: Tichifunga nezvenzvimbo yekunze yekushanda, iyo fronthaul optical module inofanirwa kusangana neindasitiri yekushisa ye -40 ℃ ~ + 85 ℃, uye inodawo kusangana neguruva zvinodiwa.
②Mutengo wakaderera: Kudiwa kwe5G optical modules kunodarika zvikuru iyo ye4G, kunyanya ye fronthaul optical modules.Mutengo wakaderera ndechimwe chezvinonyanya kudiwa kune optical modules muindasitiri ye5G.5G yepakati uye backhaul inovhara iyo yekupinda layer, aggregation layer uye musimboti wenzvimbo yemetropolitan.Izvo zvinodiwa optical modules hazvisi zvakasiyana zvakanyanya kubva kune optical module tekinoroji inoshandiswa mune yazvino data center.Iyo yekupinda layer ichanyanya kushandisa 25Gb/s, 50Gb/s, 100Gb/s Kune optical modules ye s uye mamwe mareti, DWDM optical modules ine mitengo ye100Gb/s, 200Gb/s, uye 400Gb/s ichanyanya kushandiswa pa aggregation layer uye pamusoro.
Chekupedzisira, zvinofanirwa kutaurwa kuti kukura kudiwa kweoptical modules kunonyanya kuenderana nemusika wekutaurirana data uye telecom musika.Muzera ranhasi redata, optical modules inosungirwa kuunza mikana mitsva yebudiriro.
Huanet inogona kupa marudzi ese emamodule optical, anogamuchirwa kubata nemitengo.
