Optical fiber transceiver ndi Ethernet transmission media conversion unit yomwe imasinthanitsa ma siginecha amagetsi opotoka mtunda waufupi ndi ma sign atali atali. Amagawidwa makamaka kukhala ma transceivers opanga ma single-fiber optical transceivers opangira ma fiber awiri malinga ndi zosowa zawo Kenako, tifotokoza mwatsatanetsatane kuti single-mode single-fiber / dual-fiber optical transceiver ndi chiyani? Kodi pali kusiyana kotani pakati pa single-mode single-fiber ndi single-mode dual-fiber transceivers? Achidwi, tiyeni tiwone!
Kodi single-fiber optical transceiver ndi chiyani?
Single-mode single-fiber optical fiber transceiver, zida zamtundu umodzi zimatha kusunga theka la optical fiber, ndiko kuti, kulandira deta ndi kutumiza pa fiber imodzi.
Single-fiber optical fiber transceiver: Zomwe zimalandiridwa ndikufalitsidwa zimatumizidwa pamtundu umodzi wa kuwala. Monga momwe dzinalo likusonyezera, zida zamtundu umodzi zimatha kupulumutsa theka la fiber optical, ndiko kuti, kulandira ndi kutumiza deta pa fiber imodzi, yomwe ili yoyenera kwambiri m'malo omwe zida za fiber zimakhala zolimba. Zogulitsa zamtunduwu zimagwiritsa ntchito ukadaulo wa wavelength division multiplexing, ndipo mafunde omwe amagwiritsidwa ntchito nthawi zambiri amakhala 1310nm ndi 1550nm. Komabe, chifukwa palibe mulingo wogwirizana wapadziko lonse lapansi wazogulitsa zamtundu umodzi wa fiber transceiver, zopangidwa ndi opanga osiyanasiyana zitha kukhala zosagwirizana zikalumikizidwa. Kuphatikiza apo, chifukwa chogwiritsa ntchito ma wavelength division multiplexing, zinthu za transceiver za single-fiber nthawi zambiri zimakhala ndi mawonekedwe azizindikiro zazikulu. Pakadali pano, ma transceivers ambiri opangira ma fiber pamsika ndi zinthu zamitundu iwiri. Zogulitsa zoterezi zimakhala zokhwima komanso zokhazikika, koma zimafuna ulusi wambiri wa kuwala.
Kodi single-mode dual-fiber optical transceiver ndi chiyani?
Single-mode dual-fiber optical transceiver, single-fiber bidirectional optical transceiver type ndi photoelectric conversion equipment, ubwino wake ndi kupulumutsa theka la fiber optical.
Single-fiber bidirectional optical fiber transceiver ndi chipangizo chosinthira chithunzithunzi chomwe chimagwiritsa ntchito ukadaulo wa wavelength division multiplexing kutumiza ndi kulandira deta pamtundu umodzi wa optical fiber ndikusintha ma siginecha amagetsi a netiweki ndi ma sign a kuwala. Ma transceivers a fiber optic a single-fiber bidirectional atchuka m'zaka zaposachedwa. Ubwino wake ndikuti ukhoza kupulumutsa theka la fiber optical, ndipo kusowa kwa theka la optical fiber ndikuti pakali pano palibe mgwirizano wapadziko lonse lapansi. Zogulitsa zomwe zimapangidwa ndi opanga osiyanasiyana nthawi zambiri zimakhala zogwirizana komanso zosakhazikika pang'ono poyerekeza ndi zopangidwa zamitundu iwiri. Pakadali pano, ma transceivers a fiber optic pamsika akadali olamulidwa ndi zinthu zamitundu iwiri.
Kodi pali kusiyana kotani pakati pa single-mode single-fiber ndi single-mode dual-fiber transceivers?
Single-mode multimode zimadalira chingwe kuwala. Ulusi umodzi wapawiri-ulusi umatanthawuza kupatsirana kwamtundu umodzi wamtundu umodzi kapena kutumiza kwamitundu iwiri yamagetsi; single-mode imatanthauza kugwiritsa ntchito chingwe chamtundu umodzi. Zonsezi zimagwirizanitsidwa ndi pachimake ichi, ndipo ma transceivers kumbali zonse ziwiri amagwiritsa ntchito mawonekedwe osiyanasiyana optical wavelengths, kotero amatha kutumiza zizindikiro za kuwala pachimake chimodzi. Transceiver yapawiri-fiber imagwiritsa ntchito ma cores awiri, imodzi kutumiza ndi ina kulandira, ndipo mapeto amodzi ndi mapeto otumizira ndipo mapeto ena ayenera kulowetsedwa mu doko lolandira, ndiko kuti, mbali ziwirizo ziyenera kudutsa.
Muzogwiritsira ntchito, single-mode-mode-mode-mode, kuchuluka kwa multi-mode ndipamwamba kuposa single-mode, makamaka mu wiring range zosakwana 500m, multi-mode akhoza kukumana kale, ngakhale ntchito si yabwino ngati single. - mode. Njira imodzi imagwiritsidwa ntchito m'malo opitilira 500m kapena zofunikira zazikulu za bandwidth, makamaka m'malo akuluakulu monga ntchito zamabizinesi. Chifukwa chakuti kukhazikika kwa ntchito ndi machitidwe a optical fiber modules ndi abwino kwambiri kuposa ma transceivers, m'malo ogwiritsira ntchito amodzi omwe ali ndi zofunikira zogwirira ntchito, makampani ochepa adzagwiritsa ntchito ma transceivers, koma mwachindunji amagwiritsa ntchito ma modules m'malo mwake. Pali opanga ochepa a ma transceivers a analogi ndi mitengo yapamwamba.
Ulusi umodzi ndi ulusi wapawiri nthawi zambiri zimakhala ndi madoko awiri, ndipo madoko awiri a ulusi wapawiri amakhala pafupi wina ndi mnzake. Amalembedwa TX, RX, kutumiza kumodzi ndi kulandira kumodzi, motsatana. Madoko awiri a ulusi umodzi nthawi zambiri amakhala P1. P2 ikuwonetsa kuti madoko onsewa amatha kutumizidwa ndikulandila padera, ndiye kuti, doko limodzi limagwiritsidwa ntchito kutumiza ndi kulandira, chifukwa chake limatchedwa ulusi umodzi. Ma transceivers opanga TX ndi RX amayimira kulandira ndi kutumiza. Pali mitundu iwiri ya ma transceivers opanga mawonekedwe: imodzi ndi imodzi yokha ndipo imodzi ndi yapawiri, monganso misewu yayikulu ingakhale yodzaza ngati pali mzere umodzi wokha, koma imakhala yosalala ngati ili ndi mizere iwiri, kotero. n'zoonekeratu kuti kukhazikika kwa wapawiri-mode wolandila mfundo yabwino.
Ulusi umodzi ndi kugwirizana kwa ulusi umodzi pakati pa ma transceivers awiri, ulusi wapawiri umakhala wofala, muyenera kugwiritsa ntchito ulusi umodzi, mtengo wa ulusi umodzi ndiwokwera pang'ono. Transceiver yamitundu yambiri imalandira njira zambiri zotumizira, mtunda wotumizira ndi waufupi, ndipo transceiver yamtundu umodzi imalandira njira imodzi yokha; mtunda wotumizira ndi wautali. Ngakhale kuti mitundu yambiri ikuchotsedwa, koma chifukwa cha mtengo wotsika, pali zambiri zomwe zimagwiritsidwa ntchito poyang'anira ndi kufalitsa mtunda waufupi. Ma transceivers amitundu yambiri amafanana ndi ma multi-mode optical fibers, single-mode ndi single-mode amafanana, ndipo sangathe kusakanikirana.
