Optical modules ndi zida za optoelectronic zomwe zimapanga photoelectric ndi electro-optical conversion.Mapeto otumizira optical module amasintha chizindikiro cha magetsi kukhala chizindikiro cha kuwala, ndipo mapeto olandira amasintha chizindikiro cha kuwala kukhala chizindikiro chamagetsi.Feiyu Fiber ikuwonetsa kugwiritsa ntchito ma module a kuwala m'mafakitale osiyanasiyana.Magawo akuluakulu ogwiritsira ntchito ma modules optical ndi awa: 1. Data center;2. Malo olumikizirana ndi mafoni;3. Njira yogawanitsa mafunde amphamvu;4. SAN/NAS network yosungirako;5. Netiweki ya 5G.
1. Data Center.
Deta yamakono salinso chipinda chimodzi kapena zingapo zamakompyuta, koma gulu lamagulu a data center.Kuti muzindikire ntchito yanthawi zonse ya ntchito zosiyanasiyana zapaintaneti ndi misika yogwiritsira ntchito, malo opangira ma data amafunikira kuti azigwira ntchito mogwirizana.Kusinthana kwenikweni kwa chidziwitso pakati pa malo opangira data kwapangitsa kuti pakhale kufunikira kwa ma data center interconnection network, ndipo optical fiber communication yakhala njira yofunikira kuti akwaniritse kulumikizana.
Mosiyana ndi zida zachikhalidwe zotumizira ma telecom, kulumikizana pakati pa data kumafunikira kuthamanga kwambiri, kugwiritsa ntchito mphamvu pang'ono, komanso kuwongolera pang'ono kwa zida zosinthira kuti mukwaniritse kufalitsa kwakukulu komanso kozama kwambiri.Chinthu chachikulu chomwe chimatsimikizira ngati zisudzozi zitha kuchitika ndi mawonekedwe a Optical module.
Data center communication optical modules akhoza kugawidwa m'magulu atatu malinga ndi mtundu wa kugwirizana:
(1) Kuchokera kumalo opangira deta kupita kwa wogwiritsa ntchito, amapangidwa ndi machitidwe ogwiritsira ntchito mapeto monga kupeza mtambo kuti ayang'ane pa intaneti, kutumiza ndi kulandira maimelo, ndi mitsinje yamavidiyo;
(2) Kulumikizana kwapakati pa data, komwe kumagwiritsidwa ntchito pobwereza deta, kukonzanso mapulogalamu ndi makina;
(3) Mkati mwa data center, imagwiritsidwa ntchito makamaka posungira zidziwitso, kupanga ndi migodi.Malinga ndi ulosi wa Cisco, kuyankhulana kwamkati kwa data center kumaphatikizapo 70% ya kulankhulana kwa data center.Kukula kwakukulu kwa zomangamanga za data center kwachititsanso chitukuko cha ma modules optical high-speed.
2. Masiteshoni oyambira olumikizirana ndi mafoni.
Malo olumikizirana m'manja amatanthawuza mawayilesi otumizira mauthenga omwe amatumiza uthenga pakati pa malo osinthira mauthenga a m'manja ndi malo olumikizira mafoni am'manja m'dera linalake lawayilesi.
Malo olumikizirana ndi mafoni amafunikiranso ma module owunikira kuti azindikire kulumikizana pakati pa zida.Malo oyambira ali ndi zida za RRU ndi BBU.Pakugwiritsa ntchito, tifunika kulumikiza maulalo pakati pa zida ziwirizi, zomwe zimafunikira ma module athu owoneka.Mu intaneti ya 4G, zipangizo zomwe zimagwiritsidwa ntchito pogwirizanitsa BBU ndi RRU makamaka 1.25G optical module, 2.5G optical module, 6G optical module, 10G optical module, etc.
3. Dongosolo la Passive WDM
Pakati pa mayankho aukadaulo omwe amatengedwa mu 5G fronthaul, WDM yokhazikika mosakayikira imakhala ndi gawo lalikulu kwambiri.Dongosolo la Passive WDM lili ndi gawo la kuwala, ma multiplexer ndi kuwala kwa fiber.
Mfundo yaikulu ya teknoloji ya passive wavelength division ndi kugwiritsa ntchito teknoloji ya WDM kugwirizanitsa ma siginecha owoneka ndi mafunde osiyanasiyana ndi kunyamula zidziwitso zambiri mumtolo umodzi, ndikuzitumiza mumtundu umodzi wa kuwala kuti muzindikire kufalikira pakati pa mautumiki.WDM imatha kutumiza ma siginecha angapo panthawi imodzi.Ikhoza kutumiza chizindikiro chilichonse ndi kuwala kwapadera komwe kumafanana ndi chizindikirocho, ndipo zizindikiro za kuwala kwa mafunde osiyanasiyana zimatha kupatulidwa pamapeto olandira.The passive wavelength division system makamaka ndi dongosolo lopangidwa ndi magawo awiri: color light module ndi OTM.
4. SAN/NAS network yosungirako.
Ndi chitukuko chofulumira cha intaneti ndi kugwiritsa ntchito maukonde, mitundu ya data yomwe imayenera kukonzedwa ndi njira yosungira zidziwitso ikuchulukirachulukira, zomwe zimapangitsa kuti makina osungira zidziwitso azikumana ndi zovuta zomwe sizinachitikepo.Zida zowonjezera zosungirako maukonde (Network Attached Storage, yofupikitsidwa monga NAS) ndi maukonde osungira madera (Storage Area Network, yofupikitsidwa monga SAN), amatha kulekanitsa chipangizo chosungira chidziwitso cha deta kuchokera pa intaneti ndi makina osungira, onse apakati pa kayendetsedwe ka deta, ndi Ndi scalability wabwino, amapereka njira yothandiza kwambiri kuzindikira kasamalidwe deta pakati.
Ntchito yayikulu ya netiweki yosungira ya SAN/NAS ndikusunga deta.Pakati pawo, maukonde a SAN amapangidwa makamaka ndi ma seva, ma fiber channel switch, zipangizo zosungirako, ndi zonyamulira zotumizira (optical modules, fiber jumpers);makina osungira a NAS amapangidwa makamaka ndi NAS yosungirako, masiwichi, Opangidwa ndi zida zomaliza (kompyuta), chonyamulira chotumizira (optical module, optical fiber jumper).
Tiyenera kuzindikira kuti intaneti ya SAN imagwiritsa ntchito ma Fiber Channel optical modules ndipo imayenera kuthandizira protocol ya FC Fiber Channel, pamene ma modules optical omwe amagwiritsidwa ntchito mu NAS yosungirako network amangofunika kugwirizana ndi Ethernet protocol.
5. Netiweki ya 5G.
Netiweki ya 5G imagawidwa m'magawo atatu, omwe ndi netiweki yofikira, netiweki yonyamula ndi ma core network.Kuti mumvetsetse ubale womwe ulipo pakati pawo, mutha kuloza chithunzi chotsatirachi:
Netiweki ya 5G yonyamula nthawi zambiri imagawidwa kukhala gawo lofikira kumizinda yayikulu, malo ophatikizika a metropolitan, ndi mzere woyambira wamtawuni / chigawo kuti akwaniritse ntchito zapatsogolo ndi zapakati pa ntchito za 5G.
Zochitika zodziwika bwino za 5G fronthaul zimaphatikizapo kugwirizana kwa fiber, WDM yokhazikika ndi WDM yogwira, ndi zina zotero.
Zofunikira zofananira zama module owoneka muzochitika za 5G fronthaul application ndi izi:
①Kukumana ndi kutentha kwa kalasi yamafakitale, zofunikira zodalirika kwambiri: Poganizira malo ogwirira ntchito panja, gawo la fronthaul Optical liyenera kukwaniritsa kutentha kwa mafakitale -40 ℃ ~ + 85 ℃, komanso kuyenera kukwaniritsa zofunikira za fumbi.
②Kutsika mtengo: Kufunika kwa 5G optical modules kumaposa kwambiri 4G, makamaka kwa fronthaul optical modules.Mtengo wotsika ndi chimodzi mwazinthu zofunika kwambiri zama module optical mumakampani a 5G.5G sing'anga ndi backhaul imakwirira gawo lofikira, kusanja kophatikizana ndi gawo lalikulu la mzindawu.Ma module a optical ofunikira sali osiyana kwambiri ndi teknoloji ya optical module yomwe imagwiritsidwa ntchito mu data center yamakono.Gawo lofikira lidzagwiritsa ntchito 25Gb / s, 50Gb / s, 100Gb / s Kwa ma module optical a s ndi mitengo ina, DWDM optical modules ndi mitengo ya 100Gb / s, 200Gb / s, ndi 400Gb / s idzagwiritsidwa ntchito kwambiri pa aggregation wosanjikiza ndi pamwamba.
Pomaliza, ziyenera kunenedwa kuti kufunikira kwa kukula kwa ma module optical makamaka kumadalira msika wolumikizana ndi data komanso msika wa telecom.M'zaka zamakono zamakono, ma module optical akuyenera kubweretsa mwayi watsopano wachitukuko.
Huanet atha kupereka mitundu yonse ya ma module opangira, olandiridwa kuti mulumikizane ndi mitengo.
