Fiber optic transceiver miyay tahay in loo isticmaalo labo-labo?Miyaa kala go'ay transceiver-ka fiber optic-ga?ama kaliya labo ka mid ah fiber optic transceivers ayaa loo isticmaali karaa si loo sameeyo lamaane? Haddi ay qasab tahay in transceivers-ka fiber-ka loo isticmaalo laba-labo, daruuri ma tahay calaamad iyo nooc isku mid ah? Mise waxaad isticmaali kartaa nooc kasta oo isku-dar ah?
Jawaab: Transceivers indhaha waxaa guud ahaan loo isticmaalaa labo-labo sida aaladaha beddelka korontadda. Si kastaba ha ahaatee, waxa kale oo suurtagal ah in la isticmaalo transceivers indhaha iyo fiberfurayaashatransceivers fiber iyo SFP transceivers. Mabda 'ahaan, ilaa iyo inta hirarka gudbinta indhaha isku mid yahay, isgaarsiinta Fiber-optic waxaa lagu gaari karaa isla qaab la mid ah koobiynta calaamadaha iyo taageeridda borotokool gaar ah.
Guud ahaan, laba-fiber (laba fiil oo looga baahan yahay isgaadhsiinta caadiga ah) transceivers looma kala qaybin dhamaadka gudbinta iyo dhamaadka helitaanka. Kaliya hal-fiber transceiver (kaas oo u baahan hal fiber isgaarsiinta caadiga ah) ayaa yeelan doona dhamaadka gudbinta iyo dhamaadka helitaanka.
Haddi ay tahay transceiver dual-fiber ama hal-fiber transceiver, way ku haboontahay in la isticmaalo noocyo kala duwan oo laba-labo ah. Si kastaba ha ahaatee, heerar kala duwan (100 megabits iyo gigabytes) iyo hirarka dhaadheer ee kala duwan (1310 nm iyo 1300 nm) iskuma wada socon karaan. Intaa waxaa dheer, xitaa transceiver hal-fiber ah oo isku mid ah iyo lammaane laba-fiber iyo laba-fiber ah lama wada shaqayn karo.
Transceiver-ka dual-fiber wuxuu leeyahay deked TX ah (dekedda gudbinta) iyo deked RX ah (dekedda qaadata). Labada dekedoodba waxay sii daayaan hirar isku mid ah oo ah 1310 nm, helitaankuna sidoo kale waa 1310 nm, sidaas darteed labada fiilood ee isku midka ah waxay ku xiran yihiin isku-xirnaanta. . Waxay isticmaashaa tignoolajiyada isku dhufashada ee kala qaybinta mawjadaha si ay u gudbiso oo ay u hesho laba calaamadood oo indho-indheyn ah oo dhererkoodu kala duwan yahay hal fiber optic ah. Guud ahaan waxay isticmaalaan mowjadaha dhaadheer ee 1310 nm iyo 1550 nm.
Noocyada kala duwan ee transceivers indhaha waxay taageeraan borotokoolka Ethernet. Waxay la xiriiri karaan transceivers oo isku mid ah, laakiin transceivers qaarkood waxay ku daraan qaar ka mid ah hawlaha (sida muraayadda) waxayna taageeraan borotokoolka qaarkood. Arrinka kiiska lama taageero.
