1.1 Basic basa module
Theoptical fibertransceiver inosanganisira matatu basic functional modules: photoelectric media conversion chip, optical signal interface (optical transceiver integrated module) uye magetsi emagetsi (RJ45).Kana yakashongedzerwa netiweki manejimendi mabasa, inosanganisirawo network manejimendi ruzivo rwekugadzirisa unit.
fiber optic transceiver is an Ethernet transmission media conversion unit iyo inotsinhana kure-kupfupi-yakamonyoroka-peya masaini emagetsi uye kureba-kure optical zviratidzo.Inonziwo photoelectric converter (Fiber Converter) munzvimbo dzakawanda.Chigadzirwa chacho chinowanzo shandiswa munzvimbo chaiyo yetiweki iyo iyo Ethernet tambo haigone kuvhara uye iyooptical fiberinofanira kushandiswa kuwedzera chinhambwe chekufambisa, uye inowanzoiswa muchikamu chekushandisa chebroadband metropolitan area network;panguva imwecheteyo, inobatsira kubatanidza maira yekupedzisira yeoptical fibermutsara wenzvimbo yemetropolitan Indaneti uye network yekunze yakaitawo basa rakakura.
Mune mamwe mabhizinesi akakura, optical fiber inoshandiswa senzira yekufambisa kumisa network yemusana panguva yekuvaka network, nepo nzira yekufambisa yemukati yeLAN inowanzova waya yemhangura.Nzira yekuziva sei kubatana pakati peLAN neoptical fiberbackbone network?Izvi zvinoda kutendeuka pakati pezviteshi zvakasiyana, mitsetse yakasiyana, uye akasiyana optical fiber uye inovimbisa kunaka kwekubatanidza.Kubuda kweiyo optical fiber transceivers inoshandura magetsi uye optical masaini eakamonyoroka maviri kune mumwe kune mumwe, kuve nechokwadi chekufambiswa kwakanaka kwemapaketi edata pakati pemambure maviri, uye panguva imwe chete, inowedzera muganhu wekutenderera wetiweki kubva ku100 metres. waya dzemhangura kusvika anopfuura makiromita zana (Single-mode fiber).
1.2 Hunhu hwakakosha hwefiber optic transceivers
1. Kunyatsojeka kune network protocol.
2. Ipa ultra-low latency data transmission.
3. Tsigira ultra-wide kushanda tembiricha renji.
4. Shandisa yakatsaurirwa ASIC chip kuti uone data line-kumhanyisa kutumira.Programmable ASIC inotarisisa mabasa akawanda pane imwe chip, uye ine zvakanakira dhizaini yakapusa, kuvimbika kwepamusoro, uye kuderera kwesimba rekushandisa, izvo zvinogona kuita kuti michina iwane kushanda kwepamusoro uye mutengo wakaderera.
5. Iyo network manejimendi manejimendi inogona kupa network kuongororwa, kusimudzira, mamiriro mamiriro, abnormal mamiriro mushumo uye kutonga mabasa, uye inogona kupa yakakwana yekushanda log uye alarm log.
6. Rack-mhando midziyo inogona kupa inopisa-swappable basa kuitira nyore kugadzirisa uye kusavhiringidza kukwidziridzwa.
7. Tsigira rwendo rwakakwana rwekutapurirana (0～120km).
8. Michina yakawanda inotora 1 + 1 dhizaini yemagetsi, inotsigira ultra-wide power supply voltage, uye inoziva kudzivirira kwekupa magetsi uye automatic switching.
1.3Kurongeka kwefiber optic transceivers
Kune akawanda marudzi efiber optic transceivers, uye marudzi awo anoshanduka zvinoenderana nenzira dzakasiyana dzekuisa.
Zvinoenderana nehunhu hwefiber, inogona kukamurwa kuita multi-mode fiber transceiver uye single-mode fiber transceiver.Nekuda kweakasiyana optical fibers anoshandiswa, kureba kwekufambisa kweiyo transceiver kwakasiyana.Iyo yakawanda yekufambisa kureba kwema-multi-mode transceivers iri pakati pe2 makiromita ne5 makiromita, nepo kufukidzwa kwe-single-mode transceivers kunogona kubva pamakiromita makumi maviri kusvika ku120 makiromita;
Maererano nezvinodiwa optical fiber, inogona kugoverwa kuva single-fiber optical fiber transceiver: data yakatumirwa uye inogamuchirwa inotumirwa pane imwe optical fiber;iyo mbiri-fiber optical fiber transceiver: iyo data yakagamuchirwa uye yakatumirwa inotumirwa pane maviri optical fibers.
Maererano nehuwandu hwekushanda / chiyero, inogona kugoverwa kuva 10M imwe chete, 100M fiber optic transceivers, 10 / 100M adaptive fiber optic transceivers uye 1000M fiber optic transceivers.Zvinoenderana nechimiro, inogona kukamurwa kuita desktop (yakamira-yega) fiber optic transceivers uye rack-yakaiswa fiber optic transceivers.Iyo desktop optical fiber transceiver inokodzera mushandisi mumwechete, sekusangana nekukwira kweimwe switch mukoridho.Rack-yakaiswa (modular) fiber optic transceivers inokodzera kuunganidzwa kwevashandisi vakawanda.Semuyenzaniso, iyo yepakati komputa kamuri yenharaunda inofanirwa kusangana neuplink yezvese switch munharaunda.
z maererano netiweki manejimendi, inogona kukamurwa kuita network manejimendi mhando optical fiber transceiver uye isiri-network manejimendi mhando optical fiber transceiver.
Zvinoenderana nemhando yekutarisira, inogona kukamurwa kuita isiri-network manejimendi Ethernet fiber optic transceivers: plug uye tamba, isa maitiro ekushanda echiteshi chemagetsi kuburikidza nehardware dial switch.Network manejimendi mhando Ethernet fiber optic transceiver: tsigiro mutakuri-giredhi network manejimendi
Zvinoenderana nerudzi rwemagetsi emagetsi, anogona kukamurwa kuva akavakirwa-mumagetsi fiber optic transceivers: yakavakirwa-mukati switching magetsi emagetsi anotakura-giredhi magetsi;ekunze simba fiber optic transceivers: ekunze transformer magetsi ekushandisa anonyanya kushandiswa mumidziyo yevagari vemo.Chakanakira chekare ndechekuti inogona kutsigira iyo yekupedzisira-yakafara magetsi ekupa magetsi, zvirinani kuona kudzikamisa kwemagetsi, kusefa uye kuchengetedza simba remidziyo, uye kuderedza kutadza kwekunze kunokonzerwa nekusangana kwemakanika;chakanakira chekupedzisira ndechekuti midziyo idiki muhukuru uye yakachipa.
Yakakamurwa nemaitiro ekushanda, iyo yakazara duplex mode (yakazara duplex) inoreva kuti kana kutumira nekugamuchira data kunopatsanurwa nemitsara miviri yakasiyana yekutumira, mapato ese ari mukutaurirana anogona kutumira nekugamuchira panguva imwe chete.Rudzi urwu rwekutumira Iyo modhi yakazara-duplex, uye iyo yakazara-duplex mode haidi kushandura kutungamira, saka hapana nguva inononoka inokonzerwa nekuchinja kwekushanda;
Half duplex inoreva kushandiswa kwetambo imwe chete yekufambisa kune zvese kugamuchira nekutumira.Kunyangwe data inogona kufambiswa munzira mbiri, mapato ese ari mukukurukurirana haakwanise kutumira uye kugamuchira data panguva imwe chete.Iyi nzira yekufambisa ihafu-duplex.
Kana iyo hafu-duplex modhi yagamuchirwa, iyo inofambisa uye inogamuchira pamagumo ega ega ehurongwa hwekutaurirana inotamirwa kumutsara wekutaurirana kuburikidza nekugamuchira / kutumira switch kuti uchinje nzira.Naizvozvo, kunonoka kwenguva kuchaitika.
