Transceiver Fiber Optical waa unugga beddelka warbaahinta gudbinta ee Ethernet kaas oo isweydaarsada calaamadaha korantada ee fogaan-gaaban iyo calaamadaha indhaha ee fog-fog. Marka loo eego baahiyaheeda, waxa inta badan loo kala qaybiyaa hal-fiber optic transceivers iyo dual-fiber optical transceivers. Marka xigta, waxaanu si faahfaahsan u soo bandhigi doonaa waa maxay hal-mode hal-fiber/dual-fiber optical transceiver? Waa maxay faraqa u dhexeeya hal-hab-hal-fiber iyo hal-mode-dual-fiber indhaha transceivers? Haddii aad xiisaynayso, aan eegno!
Waa maxay ahal-hab-hal-fiber-ka-qaadis-ahaaneed?
Hal-hab oo hal-fiber ah transceiver fiber indhaha, qalabka hal-fiber ah ayaa badbaadin kara kala badh fiber optic, taas oo ah, si loo gaaro xogta soo dhaweynta iyo gudbinta hal fiber indhaha.
Hal-fiber optic fiber transceiver: Xogta la helo oo la soo diro waxaa lagu kala qaadaa fiber optic ah. Sida magacu soo jeediyo, qalabka hal-fiber-ka ah wuxuu badbaadin karaa kala badh fiber-ka indhaha, taas oo ah, in la helo oo loo diro xogta hal fiber optic ah, taas oo aad ugu habboon meelaha ilaha fiber-ka ah ay ku dheggan yihiin. Noocan badeecada ah waxay isticmaashaa tignoolajiyada isku dhufashada mawjada dhererka, inta badan mawjadaha dhaadheer ee la isticmaalo waa 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 isqaadan karin marka ay isku xiran yihiin. Intaa waxaa dheer, iyadoo ay ugu wacan tahay isticmaalka isku dhufashada qaybinta mawjadaha, alaabada transceiver-ka-fiber-ka ah guud ahaan waxay leeyihiin sifooyinka calaamadaynta weyn. Waqtigan xaadirka ah, inta badan transceivers-ka fiber optic-ga ee suuqa ku jira waa badeecado laba-fiber ah, kuwaas oo aad u bislaaday oo xasiloon, laakiin u baahan fibers badan.
Waa maxay atransceiver indhaha laba-fiber?
Mid ka mid ah qaab-dhismeed-dual-fiber fiber transceiver-ka, iyo nooca hal-fiber-ka laba-geesoodka ah ee fibre-gaaban ee fiilada ah ayaa ah qalab beddelidda sawir-qaadista, taas oo faa'iido u leh badbaadinta kala badh fiber-ka.
Hal-fiber-ka laba jiho-qaade ee fibre-gaabiyaha indhaha waa aalad beddelaad koronto oo adeegsata tignoolajiyada isku-dhufashada ee qaybinta mawjada si ay u dirto oo u hesho xogta fiber-optical, oo beddeleysa calaamadaha korantada ee shabakadda iyo calaamadaha indhaha. Hal-fiber laba jiho-qaadayaasha fiber indhaha ayaa noqday kuwa aad caan u ah sannadihii u dambeeyay. Faa'iidada ayaa ah in ay badbaadin karto kala badh fiber optic ah. Ma jiro halbeeg caalami ah oo midaysan oo loogu talagalay la'aanta kala badh fiber optic-ga. Alaabooyinka ay soo saaraan soosaarayaal kala duwan ayaa guud ahaan iswaafaqaya waxayna leeyihiin xasilooni xoogaa ka liidata marka loo eego alaabada laba-fiber-ka ah. Waqtigan xaadirka ah, transceivers-ka fiber optic-ga ee suuqa ayaa wali u badan alaabooyinka fiber-ka ah.
Waa maxay farqiga u dhexeeyahal-hab hal-fiber iyo hal-hab-dual-fiber indhaha transceivers?
Hal-mode multi-mode waxay kuxirantahay fiilada indhaha, hal-fiber dual-fiber waxaa loola jeedaa gudbinta hal-core fiber ama gudbinta fiber-laba-core; Hal-mode waxa loola jeedaa isticmaalka fiilooyinka indhaha ee hal-hab ah, hal-fiber-ku-tallaalayaashu waxay isticmaalaan hal xudun oo keliya, labada daraf Labaduba waxay ku xidhan yihiin xudduntan, transceivers-yada labada darafba waxay isticmaalaan mowjadaha indhaha ee kala duwan, markaa calaamadaha indhaha ayaa lagu kala qaadi karaa hal xudun. Qalabka dual-fiber transceiver wuxuu isticmaalaa laba koofiyado, mid dirida iyo kan kale ee helitaanka, hal cidhif ah ayaa gudbinaya dhammaadka kalena waa in la geliyo dekedda wax lagu qaato, taas oo ah, labada daraf waa inay gudbaan.
Codsiga gaarka ah ee hal-hab iyo dual-mode, qadarka qaab-dhismeedku wuu ka sarreeyaa midka hal-habka ah, inta badan xargaha xargaha ee ka hooseeya 500m, qaabka badan ayaa mar hore la kulmi kara, inkasta oo waxqabadka uusan ahayn mid wanaagsan. sida hal-hab. Habka kelida ah waxaa loo isticmaalaa deegaan ka sarreeya 500m ama degaannada leh shuruudaha xajmiyeedka sare, badiyaa codsiyada baaxadda weyn ee goobta sida heerka ganacsiga. Sababtoo ah xasiloonida shaqada iyo waxqabadkamodules fiber indhahaaad ayey uga fiican yihiin transceivers, codsiyada hal-habka ah ee leh shuruudaha waxqabadka sare, shirkado yar ayaa adeegsada transceivers, laakiin waxay si toos ah u adeegsadaan modules beddelka.
Hal fiber iyo dual fiber guud ahaan waxay leeyihiin laba dekedood, labada dekedood ee fiber-ka laba-geesoodka ah ayaa aad isugu dhow. Waxaa lagu calaamadeeyay TX iyo RX, mid dirida iyo mid qaabilaadda, kuwaas oo loo qoondeeyay; Labada dekedood ee hal fiber-ka ah guud ahaan waa P1, P2 waxay tilmaamaysaa in labada dekedood ay si gaar ah wax u diri karaan waxna uga qaadan karaan, taas oo ah, hal deked ayaa loo isticmaalaa in lagu dhammeeyo diritaanka iyo soo-qaadista, sidaas darteed waxaa loo yaqaannaa hal fiber. Transceivers-yada TX iyo RX waxay matalaan helista iyo gudbinta. Waxaa jira laba nooc oo ah transceivers indhaha: mid waa hal-mode kan kalena waa dual-mode. Sida waddo leh khadadka hal haad oo keliya, waxa laga yaabaa in taraafikada ay ciriiri noqoto. Haddii ay tahay khad laba-line ah, aad bay u fududaan doontaa, markaa way iska caddahay in transceivers-ka-dual-ku ay si fiican u deggan yihiin.
Fiber kali ah waxa ay ka dhigan tahay in hal fiber kaliya loo isticmaalo in lagu xidho laba transceivers. Dual fiber waa mid aad u badan oo u baahan laba fiilood, iyo qiimaha fiber-ka kaliya ayaa xoogaa 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, weli waxaa jira codsiyo badan oo ku saabsan la socodka iyo gudbinta fogaanta gaaban sababtoo ah qiimaha hoose. Transceivers Multi-mode waxay u dhigantaa fiilooyinka indhaha ee qaab-badan, iyo hal-hab iyo hal-hab waxay u dhigmaan midba midka kale. Lama isku dari karo.
