Wixii transceivers ah fiber indhaha, shaqada ugu weyn ee transceiver waa in la kordhiyo masaafada gudbinta network, taas oo yareyn karta cilladda in fiilada shabakadu ma gudbin karin fog ilaa xad ah, oo keenaya ku haboon gudbinta kilomitir ee ugu dambeeya, laakiin kuwa ku. kuwaas oo ku cusub transceiver-ka Qaar ka mid ah khaladaadka ugu badan ee ay dadku sameeyaan, sida kala saarid la'aanta dhamaadka gudbinta iyo dhamaadka helitaanka fiber optic transceiver.Waa maxay sababta transceivers fiber optic loo qaybiyay gudbiye iyo qaataha?Ma lagu xidhi karaa dhamaadka A/B transceiver fiber optic si caadi ah?

Dhamaadka ab ee transceiver fiber optic waa inuu noqdaa dhamaadka gudbinta (dhamaadka) iyo dhamaadka helitaanka (b dhamaadka).Sababta loo qaybiyey gudbiyaha dhamaadka gudbinta iyo dhamaadka helista ayaa ah in gudbiyaha u baahan yahay in uu u gudbiyo signalka laba jiho marka la isticmaalayo, inta badan laba-labo.Dad badan ayaa suuqa ku isticmaala transceivers-ka-fiber-ka ah;Labada daraf ee transceiver-ka-fiber waa A-dhamaadka iyo B-dhamaadka siday u kala horreeyaan.Mawjadaha dhaadheer ee labadan daraf waa kala duwan yihiin.Dhererka hirarka dhammaadka gudbinta ayaa ka gaaban kan dhammaadka helaya.Dhab ahaantii, transceiver-dual-fiber ma laha dhammaadka A iyo B, sababtoo ah hirarka dhererka labada daraf waa isku mid.Kaliya marka la isku xiro dhamaadka TX (gudbinta) iyo dhamaadka RX, hal fiber, sida magaca ka muuqata, waa fiber indhaha, xirfadlayaasha qaarna waxay ugu yeeraan transceiver hal-core, taas oo loola jeedo dirida iyo helitaanka calaamadaha labada daraf ee hal fiber indhaha ah, sababtoo ah hal-mode Module-ka loo isticmaalo gudaha hal-fiber transceiver wuxuu leeyahay laba mawjadood oo iftiin ah, halka dual-fiber ay isku xiran yihiin laba fiilooyinka indhaha ah, iyo filimka gudaha ee indhaha. balooggu wuxuu leeyahay hal hirar oo keliya.

transceivers fiber indhaha waxa loo qaybiyaa hal-mode dual-fiber transceivers fiber indhaha iyo hal-mode hal-fiber indhaha transceivers iyadoo loo eegayo tirada xudunta fiber.Qalabka hal-habka ah ee hal-fiber-ka ah waxaa lagu kala qaadaa iyada oo loo marayo fiber optic ah oo udub dhexaad u ah, markaa labadaba la kala qaado iyo iftiinka la helayba waxaa lagu kala qaadaa hal xudunta fiber indhaha isku mar. Xaaladdan, si loo gaaro isgaarsiin caadi ah, laba mawjadood oo iftiin ah waa in ay noqdaan loo isticmaalo in lagu kala saaro.Sidaa darteed, moduleka indhaha ee transceiver hal-fiber hal-mode wuxuu leeyahay laba mawjadaha dhaadheer ee iftiinka, guud ahaan 1310nm/1550nm, masaafada dheerna waa 1490nm/1550nm.Sidan oo kale, waxaa jiri doona kala duwanaansho u dhexeeya labada daraf ee isku-xirnaanta lammaanaha transceivers, iyo hal daraf oo transceiver ah ayaa ka duwanaan doona.Gudbi 1310nm oo hel 1550nm.Dhamaadka kale waa in la gudbiyo 1550nm oo la helo 1310nm.Markaa way ku habboon tahay isticmaaleyaasha inay kala soocaan, xarfahana beddelkeeda guud ahaan waa la adeegsadaa.Ka dib waxaa jira a-dhamaadka (1310nm/1550nm) iyo B-dhamaadka (1550nm/1310nm).Isticmaalayaashu waa inay isticmaalaan ab pairing.Xiriirinta Aa ama bb lama ogola.
