Tikamatumiza kuchokera patali, nthawi zambiri timagwiritsa ntchito fiber kufalitsa. Chifukwa mtunda wotumizira wa fiber fiber ndi wotalikirana kwambiri, nthawi zambiri, mtunda wotumizira wa single-mode Optical fiber ndi wopitilira makilomita 10, ndipo mtunda wotumizira wamitundu yambiri umatha kufika 2 km. Mu fiber optic network, nthawi zambiri timagwiritsa ntchito ma transceivers a fiber optic. Ndiye, mungalumikize bwanji transceiver ya fiber-optic? Tiyeni titenge lingaliro.
1. Udindo wa optical fiber-optic transceivers
1. Fiber transceiver imatha kukulitsa mtunda wa kufalikira kwa Efaneti ndikukulitsa utali wozungulira wa Efaneti.
2. Transceiver ya fiber ikhoza kusinthidwa pakati pa 10M, 100M, kapena 1000M Ethernet mawonekedwe amagetsi ndi mawonekedwe a kuwala.
3, kugwiritsa ntchito optical fiber transceiver kupanga maukonde kumatha kupulumutsa ndalama zama network.
4. Fiber optic transceiver imapangitsa kuti kulumikizana pakati pa seva, kubwereza, hub, terminal ndi terminal kukhala kothandiza kwambiri.
5, fiber transceiver ili ndi microprocessor ndi mawonekedwe owunikira, imatha kupereka zidziwitso zosiyanasiyana zamagwiridwe a data.
2. Ndi iti yomwe imatsegula kapena ndi iti yomwe imalandira ma transceiver a fiber-optic?
Mukamagwiritsa ntchito cholumikizira cha fiber optical, abwenzi ambiri amakumana ndi funso lotere:
1. Kodi transceiver ya fiber optic iyenera kugwiritsidwa ntchito pawiri?
2, kuwala CHIKWANGWANI transceiver alibe mfundo, wina ayenera kulandira ndi kutumiza? Kapena ma transceivers awiri a fiber angagwiritsidwe ntchito ngati awiri?
3. Ngati transceiver ya fiber optical iyenera kugwiritsidwa ntchito pawiri, kodi awiri ayenera kukhala mtundu ndi mtundu womwewo? Kapena mutha kugwiritsa ntchito mitundu ina iliyonse?
Anzanu ambiri akhoza kukhala ndi funso ili pogwiritsira ntchito polojekiti, ndiye ndi chiyani? Yankho: optical fiber transceiver monga zida zosinthira zithunzi zimagwiritsidwa ntchito pawiri, komanso zimatha kuwoneka ngati ma transceiver owoneka bwino komanso mawonekedwe a fiber optical, transceiver optical fiber transceiver ndi SFP transceiver pairing ntchito ndizodziwikanso, makamaka, bola kutalika kwa mawonekedwe a kuwala kuli. chimodzimodzi, chizindikiro encapsulation mtundu ndi yemweyo ndi thandizo protocol akhoza kuzindikira kuwala CHIKWANGWANI kulankhula. General single mode double fiber (kulumikizana kwanthawi zonse kumafuna ma fiber awiri) transceiver mosatengera chotumizira ndi kulandira mapeto, bola awiriwo atha kugwiritsidwa ntchito. Ndi transceiver ya fiber imodzi yokha (kulankhulana kwabwinobwino kumafunikira CHIKWANGWANI) idzakhala ndi malekezero opatsirana komanso olandila.
Kaya ndi ma transceiver a fiber awiri kapena transceiver imodzi ya fiber iyenera kugwiritsidwa ntchito pawiri, mitundu yosiyanasiyana imatha kugwirizana ndi kugwirizana. Koma mlingo, wavelength, ndi chitsanzo ndizofanana. Izi zikutanthauza kuti, mitengo yosiyana (100 ndi gigabit), mafunde osiyanasiyana (1310nm ndi 1300nm) sangathe kuyankhulana wina ndi mzake, kuphatikizapo, ngakhale mtundu womwewo wa transceiver wamtundu umodzi ndi mawonekedwe amtundu wa fiber awiri sakulumikizana. Ndiye funso ndilakuti, kodi transceiver ya fiber imodzi ndi chiyani, ndipo transceiver ya fiber iwiri ndi chiyani? Kodi pali kusiyana kotani pakati pawo?
3. Kodi transceiver ya fiber single ndi chiyani? Kodi transceiver ya fiber-fiber ndi chiyani?
Single fiber transceiver imatanthawuza kugwiritsa ntchito chingwe cha single-mode optical, single fiber transceiver ndi pachimake, malekezero onsewa amalumikizidwa pachimake, malekezero onse a transceiver akugwiritsa ntchito mafunde osiyanasiyana a kuwala, kotero amatha kutumiza chizindikiro chowunikira pachimake. Pawiri CHIKWANGWANI transceiver ndi ntchito pachimake awiri, kutumiza kulandira, mbali imodzi ndi tsitsi, mapeto ena ayenera anaikapo pa doko, ndi mbali ziwiri kuwoloka.
1, single fiber transceiver
Transceiver ya fiber imodzi iyenera kuzindikira ntchito yotumizira ndi kulandira ntchito. Imagwiritsa ntchito ukadaulo wa ma wave division multiplexing kuti utumize ma siginecha awiri owoneka bwino amitundu yosiyanasiyana mu fiber optical kuzindikira kufalikira ndi kulandila.
Kotero transceiver ya single-fiber-fiber transceiver imafalitsidwa kudzera mu fiber, kotero kuwala kotumizira ndi kulandira kumafalitsidwa kudzera mu fiber core panthawi imodzimodziyo. Pankhaniyi, mafunde awiri a kuwala ayenera kugwiritsidwa ntchito kuti akwaniritse kulumikizana kwabwinobwino.
Chifukwa chake, gawo la optical la single-mode single-fiber transceivers lili ndi mafunde awiri owoneka bwino, nthawi zambiri 1310nm / 1550nm, kotero ma terminals awiri a transceivers adzakhala osiyana. Transceiver yamtundu umodzi imatumiza 1310nm ndikulandila 1550nm. Kumapeto ena, imatulutsa 1550nm ndipo imalandira 1310nm. Zosavuta kwa ogwiritsa ntchito kusiyanitsa, nthawi zambiri amagwiritsa ntchito zilembo m'malo mwake. Mapeto A (1310nm / 1550nm) ndi mapeto B (1550nm / 1310nm) adawonekera. Ogwiritsa ntchito ayenera kukhala ophatikizidwa ndi AB kuti agwiritse ntchito, osati kulumikizana kwa AA kapena BB. AB imagwiritsidwa ntchito ndi single fiber transceiver.
2, transceiver ya fiber iwiri
The double fiber transceiver ili ndi TX port (transmitting port) ndi RX port (port yolandila). Madoko onsewa ali ndi kutalika kofanana kwa 1310nm, ndipo kulandirira ndi 1310nm, kotero maulusi awiri ofananira amagwiritsidwa ntchito polumikizana.
3, momwe mungasiyanitsire transceiver imodzi ya fiber ndi transceiver ya fiber iwiri
Pali njira ziwiri zosiyanitsira ma transceivers amtundu umodzi kuchokera ku ma transceivers a fiber awiri.
① Pamene transceiver ya optical fiber imayikidwa mu optical module, transceiver ya fiber optical imagawidwa kukhala transceiver imodzi ya fiber ndi transceiver iwiri ya fiber molingana ndi chiwerengero cha optical fiber jumper cores. Transceiver ya fiber imodzi (kumanja) imalumikizidwa ndi fiber core, yomwe imayang'anira kutumiza deta ndi kulandira deta, pamene transceiver ya fiber iwiri (kumanzere) imagwirizanitsidwa ndi zingwe ziwiri za fiber, imodzi yomwe imayang'anira kutumiza deta komanso wina ali ndi udindo wolandira deta.
② Pamene transceiver ya fiber optical ilibe optical module, m'pofunika kusiyanitsa ngati transceiver ya fiber imodzi kapena transceiver yapawiri ya fiber molingana ndi gawo la optical module. Pamene transceiver optical fiber imayikidwa ndi single fiber bidirectional optical module, ndiko kuti, mawonekedwe ndi mtundu umodzi, fiber transceiver iyi (kumanja); pamene fiber transceiver imayikidwa ndi double fiber bidirectional optical module, kapena mawonekedwe ndi duplex mtundu, transceiver ndi double fiber transceiver (chithunzi chakumanzere).
4. Kuwala ndi kugwirizana kwa optical fiber transceiver
1. chizindikiro cha kuwala kwa optical fiber transceiver
Kwa kuwala kowonetsera kwa transceiver ya fiber optical, mutha kumvetsetsa kudzera pa chithunzi chotsatirachi.
2. Lumikizani optical fiber transceiver
mfundo
Kugwiritsa ntchito mfundo ndi mfundo
Kugwiritsa ntchito kwa centralized optical fiber transceiver pakuwunika kwakutali
