Marka mashaariicda hadda daciifka ah ay la kulmaan gudbinta fogaanta fog, fiber optics ayaa inta badan la isticmaalaa. Sababtoo ah fogaanta gudbinta fiber-ka indhaha aad ayey u dheer tahay, guud ahaan, masaafada gudbinta ee fiber-ka-hal-qashinku waa in ka badan 10 kiiloomitir, masaafada gudbinta fiber-ka-habka badan waxay gaari kartaa ilaa 2 kiiloomitir.
Shabakadaha fiber optic-ga, waxaan inta badan isticmaalnaa transceivers fiber optic. Marka, sida loo xiro transceivers fiber optic? Aan isla eegno.
Marka hore, doorka fiber optic transceivers
① Transceiver fiber optic wuxuu kordhin karaa fogaanta gudbinta ee Ethernet wuxuuna kordhin karaa radius-ka daboolida Ethernet.
② Transceiver fiber optic ah ayaa karabeddelointa u dhaxaysa 10M, 100M ama 1000M Ethernet interface koronto iyo interface indhaha.
③ Isticmaalka transceivers fiber optic si loo dhiso shabakad waxay badbaadin kartaa maalgashiga shabakada.
④ Transceivers fiber indhaha ayaa ka dhigaya isku xidhka u dhexeeya server-yada, soo-celinta, hub-yada, terminalka iyo terminalka si dhakhso ah.
⑤ Transceiver fiber optic ayaa leh microprocessor iyo interface ogaanshaha, kaas oo bixin kara xogta kala duwan ee xogta waxqabadka.
Marka labaad, waa kuwee transceiver uu leeyahay transceiver indhaha iyo mid ka mid ah uu helo?
Marka la isticmaalayo transceivers fiber indhaha, saaxiibo badan ayaa la kulmi doona su'aalahan oo kale:
1.Ma transceivers fiber indhaha waa in loo isticmaalo labo-labo?
2.Miyuu u qaybsan yahay transceiver fiber optic-ga mid helida iyo mid gudbinta? Mise kaliya laba transceivers indhaha ayaa loo isticmaali karaa labo ahaan?
3. Haddii transceivers fiber indhaha waa in loo isticmaalo labo-labo, lagama maarmaan ma tahay in ay isku nooc iyo isku mid yihiin? Mise wax calaamad ah ayaa loo isticmaali karaa marka la isku daro?
Jawaab: Fiber optic transceivers-ka guud ahaan waxaa loo isticmaalaa labo-labo sida aaladaha beddelka koronto-dhaliyaha, laakiin sidoo kale waa suurtogal in la isku dhejiyo fiber optic transceivers iyo fiberfurayaashatransceivers fiber optic iyo SFP transceivers. Mabda 'ahaan, ilaa inta mawjadaha gudbinta indhaha isku mid yihiin Qaabka encapsulation signal waa isku mid oo labaduba waxay taageeraan borotokool gaar ah si loo gaaro isgaarsiinta fiber optic.
Guud ahaan, hal-mode dual-fiber (laba fibre ayaa looga baahan yahay isgaarsiinta caadiga ah) transceivers looma kala qaybin dhamaadka gudbinta iyo dhamaadka helitaanka, waxaana la isticmaali karaa ilaa inta ay u muuqdaan laba-labo.
Kaliya hal-fiber transceiver (hal fiber ayaa looga baahan yahay isgaarsiinta caadiga ah) ayaa yeelan doona dhamaadka gudbinta iyo dhamaadka helista.
Si kale haddii loo dhigo, heerarka kala duwan (100M iyo Gigabit) iyo hirarka dhererka kala duwan (1310nm iyo 1300nm) ma wada xiriiri karaan midba midka kale. Intaa waxaa dheer, xitaa haddii hal fiber transceiver iyo laba fiber oo isku mid ah ay isku mid yihiin, suurtagal maaha in la wada hadlo midba midka kale. La wada shaqayn karo.
Haddaba su'aashu waxay tahay, waa maxay hal-abuurka fiber-ka, waa maxay transceiver-ka laba-geesoodka ah? Maxay ku kala duwan yihiin iyaga?
Waa maxay transceiver-ka-fiber? Waa maxay transceiver-dual-fiber?
Transceiver-ka-fiber-ka waxa loola jeedaa fiilada indhaha ee hal-hab ah. Transceiver-ka-fiber-ku wuxuu isticmaalaa hal xudun oo keliya labada darafna waxay ku xidhan yihiin xuduntan. Transceivers ee labada cidhifba waxay isticmaalaan mowjadaha dhererka indhaha ee kala duwan, si ay ugu gudbiyaan hal calaamad oo iftiin ah.
Dual-fiber transceiver waxa ay isticmaashaa laba geesood, midna gudbinta iyo mid soo dhawaynta, midna cidhifku waa in la geliyo cidhifka kale, labada cidhifna waa in la dhaafaa.
1.Qalabka kaliya ee fiber-ka
Transceiver-ka-fiber-ku waa inuu fuliyaa shaqada gudbinta iyo shaqada helista labadaba. Waxay isticmaashaa tignoolajiyada isku dhufashada ee kala qaybinta mawjadaha si ay u gudbiso oo ay u hesho laba calaamadood oo indhaha ah oo leh hirar kala duwan oo hal fiber indhaha ah.
Sidaa darteed, transceiver-ka-hal-qaab-hal-fiber ah waxa lagu kala qaadaa iyada oo loo marayo fiber optic-ga udub-dhexaadka ah, sidaas awgeed gudbinta iyo helitaanka iftiinka waxaa lagu kala qaadaa xudunta fiber-ka isku mar. Xaaladdan oo kale, si loo gaaro isgaarsiin caadi ah, laba mawjadaha iftiinka waa in la isticmaalo si loo kala saaro.
Sidaa darteed, moduleka indhaha ee transceiver-ka-fiber-ka-hal-hal-laha ah wuxuu leeyahay laba mawjadood oo dhaadheer oo iftiin la sii daayo, badiyaa 1310nm / 1550nm. Sidan, waxaa jira farqi u dhexeeya labada daraf ee lammaaneyaasha transceivers:
Transceiver-ka halka dhamaadka ah wuxuu gudbiyaa 1310nm wuxuuna helayaa 1550nm.
Dhamaadka kale ayaa sii daaya 1550nm oo helaya 1310nm.
Markaa way ku habboon tahay isticmaalayaashu inay kala soocaan, oo guud ahaan beddelka xarfaha isticmaalaan.
A-terminal (1310nm/1550nm) iyo B-terminal (1550nm/1310nm) ayaa soo muuqday.
Isticmaalayaashu waa inay adeegsadaan isku-xidhka AB, maaha inay isticmaalaan isku-xidhka AA ama BB.
Dhamaadka AB waxa kaliya loo isticmaalaa transceivers-ka fiber optic-ga ah.
2.Dual fiber transceiver
Transceiver-ka dual-fiber wuxuu leeyahay deked TX ah (dekedda gudbinta) iyo deked RX ah (deked qaadata). Labada dekedoodba waxay ku kala gudbiyaan mawjadaha dhererka isku midka ah ee 1310nm, soo dhawayntuna sidoo kale waa 1310nm. Sidaa darteed, labada fiilooyinka indhaha ee isbar-barya ee loo isticmaalo xargaha ayaa ah kuwo isku xiran.
3. Sidee lagu kala soocaa transceiver-ka kaliya ee fiber-ka iyo transceiver-ka laba-geesoodka ah?
Hadda waxa jira laba siyaabood oo lagu kala sooco transceivers-ka-fiber-ka ah iyo transceivers-ka laba-fiber.
①Marka transceiver indhaha lagu dhejiyo module indhaha ah, transceiver indhaha waxa loo qaybiyaa transceiver hal-fiber ah iyo transceiver dual-fiber iyadoo loo eegayo tirada xudunta ee jumper fiber indhaha isku xidhan. linearity ee jumper fiber indhaha ee ku xidhan transceiver hal-fiber (midig) waa xudunta fiber, kaas oo mas'uul ka ah gudbinta iyo helitaanka xogta labadaba; Khadka toosan waa laba geesood. Mid ka mid ah xudunta ayaa mas'uul ka ah gudbinta xogta iyo xudunta kale ayaa mas'uul ka ah helitaanka xogta.
②Marka transceiver fiber optic ah uusan lahayn module indhaha ku dhejisan, waxaa lagama maarmaan ah in la kala saaro inta u dhaxaysa hal fiber transceiver iyo transceiver fiber dual sida waafaqsan moduleka indhaha la geliyo. Marka qaab-dhismeedka laba-geesoodka ah ee hal-fiber ah la geliyo transceiver fiber optic, taas oo ah, interface-ku waa nooca simplex, transceiver fiber optic waa hal-fiber transceiver (sawirka saxda ah); marka moduleka laba-geesoodka ah ee laba-fiber ah la geliyo transceiver-ka fiber-ka, Taas oo ah, marka interface-ku yahay nooc-duplex, transceiver-kani waa transceiver-dual-fiber (sawirka bidix).
