Pakali pano, pali ambiri akunja ndi zoweta opangafiber optic transceiversmumsika, ndipo mizere yazogulitsa ndi yolemera kwambiri. Mitundu ya ma transceivers a fiber optic imakhalanso yosiyana, makamaka imagawidwa kukhala ma transceivers opangidwa ndi rack-mounted optical transceivers, ma transceivers optical optical and card-type optical transceivers.

Optical fiber transceiver ndi Ethernet transmission media conversion unit yomwe imasinthanitsa ma siginecha amagetsi opindika mtunda waufupi ndi ma sign atali atali. Amatchedwanso photoelectric converter m'malo ambiri ndipo amagwiritsidwa ntchito muzida zoyankhulirana zowoneka bwino.

Zowonjezereka kuposa zowonjezereka. Zida zotumizira ma fiber monga telefoni optical transceivers ndi optical fiber access zida zingathe kufalikira pakati pa zipangizo kudzera mu transceivers optical. Nthawi zambiri, ma transceivers owoneka amagawidwa kukhala amodzi-mode ndi ma multi-mode, single-fiber ndi dual-fiber. Mtundu wokhazikika wa mawonekedwe ndi SC. FC, LC, etc. angathenso kukhazikitsidwa malinga ndi zosowa za makasitomala. Mtunda wotumizira nthawi zambiri ndi makilomita 25, makilomita 40, makilomita 60, ndi makilomita 80. , 100 makilomita, 120 makilomita, etc.

Ma transceivers opanga mawonekedwe amodzi komanso osiyanasiyana

Njira imodzi imatanthawuza kuti chizindikiro cha kuwala chimafalikira kudzera mu njira imodzi, pamene njira ziwiri kapena zambiri zimakhala zofanana ndipo zimafalikira kudzera munjira ziwiri kapena zingapo. Wogwiritsa ntchito akasankha kutumiza kudzera pa single-mode kapena multi-mode, chinthu chachikulu chomwe chimamutsimikizira ndi mtunda womwe wogwiritsa ntchito ayenera kutumiza. Kupatsirana kwamtundu umodzi kumakhala ndi kuchepetsedwa pang'ono, koma liwiro lotumizira limachepera. Ndizoyenera kufalitsa mtunda wautali. Nthawi zambiri, mtunda ndi waukulu kuposa 5 miles. Ndi bwino kusankha fiber single-mode. Multimode kufala ali attenuation yaikulu, koma liwiro kufala ndi mofulumira. Pakutumiza mtunda waufupi, nthawi zambiri mtunda umakhala wochepera 5 mailosi, ndipo ma multimode fiber ndiye chisankho chabwino kwambiri.

Single fiber ndi dual fiber optical transceiver

Chingwe chimodzi chimatanthawuza chingwe chimodzi chokha chomwe chimadutsa pachikatikati; Ulusi wapawiri umatanthawuza ulusi wapawiri-core optical fiber womwe umadutsa pamitundu iwiri, imodzi yolandira ndi ina yotumiza. Kawirikawiri, ogwiritsa ntchito nthawi zambiri amagwiritsa ntchitoulusi wapawiri, chifukwa dual-fiber ndi yopindulitsa kwambiri potengera mtengo. Ulusi umodzi nthawi zambiri umagwiritsidwa ntchito ngati chingwe cha kuwala chili cholimba. Mwachitsanzo, ngati 12-core fiber ndi yapawiri-core, maukonde 6 okha ndi omwe amatha kufalikira; ngati 12-core fiber ndifiber imodzi, 50% ya mawaya amatha kupulumutsidwa.

FC, SC, LC Optical transceiver

FC, SC, ndi LC ndi mtundu wa mawonekedwe a pigtail, ndipo SC ndi mawonekedwe omwe amagwiritsidwa ntchito kwambiri pa pigtail. Mukamagula mawonekedwe a transceiver owoneka, samalani ngati mawonekedwewa akufanana ndi mawonekedwe a pigtail omwe mumapereka. Zachidziwikire, palinso mitundu yambiri ya zingwe zamagetsi pamsika, monga FC kumapeto kwina ndi SC kumapeto kwina.SFP Optical modulesamagwiritsidwa ntchito pafupipafupi mu LC.

Mtunda wopatsirana wa transceiver owoneka umatengera kusankha kwa wogwiritsa ntchito kwenikweni, ndipo mtunda wopatsirana pakati pa zida ziwirizi ukhoza kusankhidwa molingana ndi transceiver yofananira.

Chidule: Posankha optical fiber transceiver, samalani kwambiri ndikugwiritsa ntchito. Ngati transceiver yolakwika yasankhidwa, zingayambitse ofesi kapena telefoni yakutali optical transceiver kapena zipangizo zina kuti zisagwire ntchito bwino kapena mawonekedwe a pigtail sangathe kulumikizidwa. Vuto latsatanetsatane lingakhale Funsani wopanga kuti muwonetsetse kuti mwagula zinthu zoyenera.
