Optical fiber transceiver ndi Ethernet transmission media conversion unit yomwe imasinthanitsa ma siginecha amagetsi opotoka mtunda waufupi ndi ma sign atali atali. Malingana ndi zosowa zake, zimagawidwa makamaka kukhala ma transceivers optical optical transceivers ndi awiri-fiber optical transceivers.Kenako, tidzafotokozera 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 optical transceivers? Ngati mukufuna, tiyeni tiwone!

Kodi asingle-mode single-fiber Optical transceiver?

Single-mode single-fiber optical fiber transceiver, zida zamtundu umodzi zimatha kupulumutsa theka la optical fiber, ndiko kuti, kukwaniritsa kulandira ndi kutumiza deta pamtundu umodzi wa kuwala.

Single-fiber optical fiber transceiver: Zomwe zalandilidwa ndikutumizidwa zimatumizidwa pa fiber optical. Monga momwe dzinalo likusonyezera, zida zamtundu umodzi zimatha kupulumutsa theka la fiber optical, ndiko kuti, kulandira ndi kutumiza deta pa fiber imodzi ya optical, yomwe ili yoyenera kwambiri kumalo omwe zipangizo za optical fiber zimakhala zolimba. Zogulitsa zamtunduwu zimagwiritsa ntchito ukadaulo wogawa wavelength division multiplexing, ndipo mafunde ambiri omwe amagwiritsidwa ntchito ndi 1310nm ndi 1550nm. Komabe, chifukwa palibe mulingo wogwirizana wapadziko lonse wa zinthu za transceiver za fiber imodzi, zopangidwa ndi opanga osiyanasiyana zitha kukhala zosagwirizana zikalumikizidwa. Kuphatikiza apo, chifukwa chogwiritsa ntchito ma wavevelength division multiplexing, zinthu za transceiver za single-fiber nthawi zambiri zimakhala ndi mawonekedwe azizindikiro zazikulu. Pakalipano, ma transceivers ambiri a fiber optic pamsika ndi zinthu ziwiri za fiber, zomwe zimakhala zokhwima komanso zokhazikika, koma zimafuna ulusi wambiri.

Kodi asingle-mode dual-fiber Optical transceiver?

The single-mode dual-fiber optical fiber transceiver, ndi single-fiber bidirectional optical fiber transceiver mtundu ndi zida zosinthira zithunzi, zomwe zimakhala ndi mwayi wopulumutsa theka la fiber.

Single-fiber bidirectional optical fiber transceiver ndi photoelectric conversion device yomwe imagwiritsa ntchito teknoloji ya wavelength division multiplexing kutumiza ndi kulandira deta pa fiber optical, ndikusintha zizindikiro zamagetsi zamagetsi ndi zizindikiro za kuwala. Ma transceivers a fiber single-fiber bidirectional optical fiber atchuka kwambiri m'zaka zaposachedwa. Ubwino wake ndikuti ukhoza kupulumutsa theka la fiber optical. Palibe mulingo wogwirizana wapadziko lonse lapansi wakusowa kwa theka la fiber optical. Zogulitsa zopangidwa ndi opanga osiyanasiyana nthawi zambiri zimakhala zogwirizana ndipo zimakhala zokhazikika pang'ono kuposa zopangidwa ndi ma fiber awiri. Pakadali pano, ma transceivers a fiber optic pamsika akadali olamulidwa ndi zida zapawiri.

Kodi pali kusiyana kotanisingle-mode single-fiber ndi single-mode dual-fiber optical transceivers?

Single-mode Mipikisano mode zimadalira chingwe kuwala, ulusi umodzi wapawiri CHIKWANGWANI amatanthauza umodzi wapakati CHIKWANGWANI kufala kapena awiri-pakati CHIKWANGWANI kufala; single-mode imatanthawuza kugwiritsa ntchito zingwe zowonera zamtundu umodzi, ma transceivers amtundu umodzi amagwiritsa ntchito pachimake chimodzi, malekezero onse awiri amalumikizidwa pachimake ichi, ndipo ma transceivers pamagawo onse awiri amagwiritsa ntchito mawonekedwe osiyanasiyana optical wavelengths, kotero kuti mawotchi owoneka amatha kufalikira mkati. core imodzi. Transceiver yapawiri-fiber imagwiritsa ntchito ma cores awiri, imodzi yotumizira ndi ina kulandira, mbali imodzi imatumiza ndipo ina iyenera kulowetsedwa mu doko lolandira, ndiko kuti, mbali ziwirizo ziyenera kuwoloka.

Pogwiritsa ntchito njira imodzi yokha komanso yapawiri, kuchuluka kwa mitundu yambiri ndipamwamba kuposa ya single-mode, makamaka muzitsulo zosachepera 500m, multi-mode imatha kukumana, ngakhale kuti ntchitoyo si yabwino. ngati single-mode. Njira imodzi imagwiritsidwa ntchito m'malo opitilira 500m kapena m'malo omwe ali ndi zofunikira zazikulu za bandwidth, makamaka m'magawo akulu akulu monga mabizinesi. Chifukwa kukhazikika kwa ntchito ndi magwiridwe antchito aOptical fiber modulesndi abwino kwambiri kuposa ma transceivers, muzogwiritsira ntchito zamtundu umodzi wokhala ndi zofunikira zogwirira ntchito, makampani ochepa amagwiritsa ntchito ma transceivers, koma amagwiritsa ntchito ma modules mwachindunji m'malo mwake.

Ulusi umodzi ndi ulusi wapawiri nthawi zambiri zimakhala ndi madoko awiri, ndipo madoko awiri a ulusi wapawiri amakhala oyandikana. Amalembedwa ndi TX ndi RX, imodzi yotumiza ndi ina yolandira, yomwe imasankhidwa; madoko awiri a ulusi umodzi nthawi zambiri ndi P1, P2 ikuwonetsa kuti madoko onsewa amatha kutumiza ndi kulandira padera, ndiye kuti, doko limodzi limagwiritsidwa ntchito kumaliza kutumiza ndi kulandira, motero 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 ina ndi yapawiri. Mofanana ndi msewu wokhala ndi mizere imodzi yokha, magalimoto angakhale odzaza. Ngati ndi mizere iwiri, idzakhala yosalala kwambiri, choncho n'zoonekeratu kuti ma transceivers amtundu wapawiri amakhala okhazikika bwino.

Chingwe chimodzi chimatanthawuza kuti ulusi umodzi wokha umagwiritsidwa ntchito kulumikiza ma transceivers awiri. Ulusi wapawiri umakhala wofala kwambiri ndipo umafunika ulusi uwiri, ndipo 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 ma multimode akuchotsedwa, palinso ntchito zambiri pakuwunika ndi kufalitsa mtunda waufupi chifukwa cha mtengo wotsika. Ma transceivers amitundu yambiri amafanana ndi ma multi-mode optical fibers, ndipo single-mode ndi single-mode imagwirizana. Iwo sangakhoze kusakaniza.
