Transceiver Fiber Optical waa unugga beddelka warbaahinta gudbinta ee Ethernet kaas oo beddela calaamadaha korantada ee fogaanta-gaaban iyo calaamadaha indhaha ee fog-fog.Inta badan waxa loo kala qaybiyaa hal-fiber optic transceivers iyo dual-fiber optical transceivers sida ay u baahan yihiin Marka xigta, waxaan si faahfaahsan u soo bandhigi doonaa waa maxay hal-hab-hal-fiber / dual-fiber optical transceiver?Waa maxay faraqa u dhexeeya hal-hab-hal-fiber iyo hal-hab-dual-fiber transceivers?Asxaabta xiisaha lihi, aan eegno!
Waa maxay transceiver indhaha hal-fiber ah?
Hal-hab oo hal-fiber ah, qalabka hal-fiber-ka ah ayaa badbaadin kara kala badh fiber-ka indhaha, taas oo ah, soo-dhoweynta xogta iyo gudbinta hal fiber.
Hal-fiber optic fiber transceiver: Xogta la helo oo la kala qaado waxaa lagu kala qaadaa hal fiber optic ah.Sida magacu tilmaamayo, qalabka hal-fiber-ka ah ayaa badbaadin kara kala badh fiber optic ah, taas oo ah, in la helo oo loo diro xogta hal fiber, taas oo aad ugu habboon meelaha ilaha fiber-ku ku dheggan yihiin.Alaabta noocan ah waxay isticmaashaa tignoolajiyada isku dhufashada kala qaybinta mawjadaha dhererka dhererka, dhererka hirarka la isticmaalo ayaa u badan 1310nm iyo 1550nm.Si kastaba ha ahaatee, sababtoo ah ma jiro halbeeg caalami ah oo midaysan oo loogu talagalay alaabada transceiver-ka-fiber-ka ah, badeecadaha soosaarayaasha kala duwan waxay noqon karaan kuwo aan ku haboonayn marka la isku xiran yahay.Intaa waxaa dheer, iyadoo ay ugu wacan tahay isticmaalka isku dhufashada qaybinta mawjadaha, alaabada transceiver-ka-fiber-ka ah guud ahaan waxay leeyihiin sifooyin yareynta calaamadaha waaweyn.Waqtigan xaadirka ah, badiyaa transceivers fiber indhaha ee suuqa waa alaabo-dual-fiber ah.Alaabooyinka noocaan oo kale ah waa kuwo bislaaday oo xasiloon, laakiin waxay u baahan yihiin fiilooyinka indhaha.
Waa maxay transceiver optical dual-fiber ee hal-hab ah?
Hal-mode dual-fiber optical transceiver, nooca transceiver indhaha laba-fiber ah waa qalab beddelka photoelectric, faa'iidada waa in la badbaadiyo kala bar fiber indhaha.
Transceiver-ka laba-geesoodka ah ee fiber indhaha ah waa aalad beddelaad koronto oo adeegsata tignoolajiyada isku-dhufashada ee kala qaybinta mawjada si ay u gudbiso oo u hesho xogta hal fiber indhaha ah una beddelo calaamadaha korantada ee shabakadda iyo calaamadaha indhaha.Gudbiyeyaasha hal-geeska ah ee fiber optic-ga ah ayaa caan noqday sannadihii u dambeeyay.Faa'iidada ayaa ah in ay badbaadin karto kala badh fiber-ka indhaha, iyo la'aanta kala badh fiber-ka indhaha ayaa ah in aysan hadda jirin halbeeg caalami ah oo midaysan.Alaabooyinka ay soo saaraan soosaarayaal kala duwan ayaa guud ahaan iswaafaqaya oo xoogaa ka xasiloon marka loo eego alaabada laba-fiber-ka ah.Waqtigan xaadirka ah, transceivers-ka fiber optic-ga ee suuqa ayaa wali u badan wax soo saarka fiber-dual-fiber.
Waa maxay faraqa u dhexeeya hal-hab-hal-fiber iyo hal-hab-dual-fiber transceivers?
Hal-mode multimode waxay ku xiran tahay fiilada indhaha.Hal-fiber dual-fiber waxaa loola jeedaa gudbinta fiber indhaha hal-core ama gudbinta fiber indhaha laba-core;hal-hab waxa loola jeedaa isticmaalka fiilada fiber indhaha ee hal-hab ah.Labaduba waxay ku xidhan yihiin xuduntan, transceivers-yada labada darafba waxay isticmaalaan mowjadaha indhaha ee kala duwan, si ay u gudbiyaan calaamadaha indhaha ee hal xudun ah.Qalabka dual-fiber transceiver wuxuu isticmaalaa laba koofiyado, mid wax dira iyo mid aqbala, midna dhamaadka waa dhamaadka diritaanka iyo dhamaadka kale waa in la geliyo dekedda hesha, taas oo ah, labada daraf waa inay gudbaan.
Codsiyada gaarka ah, hal-hab-dual-mode, qadarka qaab-dhismeedka badan ayaa ka sarreeya hal-hab, inta badan xadhkaha fiilooyinka ee ka yar 500m, qaabka badan ayaa mar hore la kulmi kara, inkastoo waxqabadka uusan u fiicneyn sida hal. -habkaHabka kelida ah waxaa loo isticmaalaa deegaanka in ka badan 500m ama shuruudaha xajmiyeedka sare, inta badan goobaha baaxadda leh sida codsiyada heerka ganacsiga.Sababtoo ah xasiloonida shaqada iyo waxqabadka modules fiber optics ayaa aad uga fiican kuwa transceivers, goobaha codsiga hal-mode leh shuruudaha waxqabadka sare, shirkado yar ayaa isticmaali doona transceivers, laakiin si toos ah u isticmaalaan modules halkii.Waxaa yaraaday soosaarayaasha analogga ah iyo qiimayaal sare.
Hal fiber iyo dual fiber guud ahaan waxay leeyihiin laba dekedood, labada dekedood ee fiber-dual-ka ayaa isku dhow.Waxaa lagu calaamadeeyay TX, RX, mid gudbinta iyo mid helaya, siday u kala horreeyaan.Labada dekedood ee fiber-ka keliya waa guud ahaan P1.P2 waxay tilmaamaysaa in labada dekedood si gooni ah loo diri karo oo loo qaadan karo, taas oo ah, hal deked ayaa la isku diro oo la soo dejiyaa, sidaas darteed waxaa loo yaqaan 'single fiber'.Transceivers-ka indhaha ee TX iyo RX waxay matalaan helista iyo dirida.Waxaa jira laba nooc oo ah transceivers indhaha: mid waa hal-mode midna waa dual-mode, si la mid ah waddooyinka waaweyn waxaa laga yaabaa inay ciriiri noqdaan haddii uu jiro kaliya hal-line, laakiin aad ayey u jilicsan tahay haddii ay tahay laba-line, sidaas darteed. waa wax iska cad in xasiloonida labada qaab ee qaataha dhibic wanaagsan.
Fiber-ka kali ahi waa kaliya hal fiber oo isku xidha labada transceivers, dual fiber waa mid aad u badan, waxaad u baahan tahay inaad isticmaasho laba fiilood, qiimaha hal fiber-ka ayaa waxyar ka sarreeya.Transceiver multi-mode wuxuu helayaa habab kala duwan oo gudbin ah, fogaanta gudbintu waa mid gaaban, iyo hal-hab-qabashada kaliya waxay helaysaa hal qaab;Fogaanta gudbintu waa mid dheer.Inkasta oo qaababka badan la tirtiray, laakiin sababtoo ah qiimaha hoose, weli waxaa jira kuwo badan oo loo isticmaalo kormeerka iyo gudbinta fogaanta gaaban.Transceivers multi-mode waxay u dhigantaa fiilooyin muuqaal ah oo qaab-badan leh, hal-hab iyo hal-qaab ayaa u dhigma, lamana qasi karo.
