Kwa ma transceivers opanga kuwala, kaya ulusi umodzi kapena ulusi wapawiri ndi wabwinoko, choyamba tiyeni timvetsetse kuti ulusi umodzi ndi ulusi wapawiri ndi chiyani.

Chingwe chimodzi: Zomwe zalandilidwa ndikutumizidwa zimatumizidwa pamtundu umodzi wa kuwala.
Ulusi Wapawiri: Zomwe zalandilidwa ndikutumizidwa zimatumizidwa pamitundu iwiri yayikulu motsatana.

Ma module a single-fiber bidirectional optical ndi okwera mtengo kwambiri, koma amatha kusunga gwero limodzi la fiber, lomwe ndi chisankho chabwinoko kwa ogwiritsa ntchito omwe ali ndi fiber zosakwanira.
Dual-fiber bidirectional optical module ndiyotsika mtengo, koma fiber imodzi imafunikira.Ngati zida za ulusi ndizokwanira, mutha kusankha ma module amtundu wapawiri-fiber.

Ndiye kubwerera ku funso lapitalo, kodi ulusi umodzi kapena ulusi wapawiri uli bwino kwa transceiver ya kuwala?

Ma transceivers optical single-fiber amatha kupulumutsa theka la zida za fiber chingwe, ndiko kuti, kutumiza deta ndi kulandila pa fiber imodzi, yomwe ili yoyenera kwambiri kumalo omwe zida za fiber zimakhala zolimba;pamene ma transceivers optical optical awiri amafunika kukhala ndi ma fiber optical fiber awiri, chigawo chimodzi chimagwiritsidwa ntchito pofalitsa (Tx) Chigawo chimodzi chimagwiritsidwa ntchito kulandira (Rx).Mafunde amtundu wa single-fiber optical transceivers ndi 1310nm ndi 1550nm kuti agwiritse ntchito pawiri, ndiye kuti, malekezero amodzi ndi 1310 wavelength, ndipo malekezero ena ndi 1550 wavelength, omwe amatha kutumiza kapena kulandira.

Ma transceivers opangidwa ndi fiber-fiber optical onse amakhala ndi mawonekedwe ofananirako, ndiko kuti, zida zomwe zili mbali zonse zimagwiritsa ntchito utali wofanana.Komabe, popeza palibe mulingo wogwirizana wapadziko lonse lapansi wazogulitsa zamagetsi zamagetsi, pangakhale kusagwirizana pakati pa zinthu zopangidwa ndi opanga osiyanasiyana zikalumikizidwa.Kuphatikiza apo, chifukwa chogwiritsa ntchito mawonekedwe a wavelength division multiplexing, ma transceiver optical single-fiber optical transceiver ali ndi zovuta zochepetsera chizindikiro, ndipo kukhazikika kwawo kumakhala koyipa pang'ono kuposa zinthu ziwiri za fiber, ndiko kuti, ma transceivers optical single-fiber ali ndi zofunika zapamwamba zama module optical, kotero ma transceivers opanga ma single-fiber optical pamsika ndi ofanana ndi Dual-fiber optical transceivers nawonso ndi okwera mtengo.

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, palinso ntchito zambiri pakuwunika ndi kufalitsa mtunda waufupi chifukwa cha mtengo wotsika.Ma transceivers amitundu yambiri amafanana ndi ulusi wamitundu yambiri, ndipo single-mode ndi single-mode imagwirizana.Iwo sangakhoze kusakanikirana.

Pakalipano, ma transceivers ambiri opangira kuwala pamsika ndi zinthu ziwiri za fiber, zomwe zimakhala zokhwima komanso zokhazikika, koma zimafuna zowonjezera zowonjezera chingwe.
