Telefoonku transceiver indhaha ma fududahay in la isticmaalo? Dabcan way fududahay in la isticmaalo, haddii kale ma noqon doonto wax soo saarka horumarinta taariikheed ee qalabka isgaarsiinta! Telephone optical transceiver waa aalad beddesha calaamadaha taleefoonada ee soo jireenka ah ee...

Noocyada isku xirka taleefanka ee caadiga ah ee la isticmaalo transceivers indhaha telifoonada waa: loop relay interface (FXO), isku xirka khadka macaamiisha analogga ah (FXS), Interface telephone-ka khadka (telefoonka rasmiga ah), interneedka telefoonka magnetka. Taleefoonka transceivers indhaha...

8-dekedda POE network biiro "Weligaa gubin qalab" smart POE, horumarsan is-dareen algorithm awood kaliya IEEE 802.3af terminal qalabka, sidaas darteed ma jirto baahi loo qabo in laga walwalo waxyeelo gaar ah heerka PoE ama qalabka non-PoE. Nidaamka korantada ee caqliga leh...

Siddeed-dekedood ee POE beddelka (JHA-P30208CBMH) waxay bixisaa awood iyo gudbinta xogta iyadoo la adeegsanayo fiilooyinka Qaybta 5 Ethernet ee qanjidhada shabakadda. 8+2 dekedaha degdega ah ee Ethernet waxaa loo isticmaali karaa isku xirka 10/100Mps, kuwaas oo 8 ka mid ah ay bixin karaan heerka warshadaha IEEE802

Dadka inta badan iibsada modules indhaha waxay og yihiin in modules-yada fiber-ka ah ay badanaa u baahan yihiin inay xaqiijiyaan koodhka iswaafajinta, sababtoo ah hadda waxaa jira laba nooc oo suuqa ah, mid waa moduleka ku habboon waxqabadka sare, kan kalena waa moduleka indhaha ee ori. .

Furaha PoE waxa loola jeedaa beddelka bixin kara sahayda korantada shabakadda ee teerminnada tamarta fog leh iyada oo loo marayo fiilada shabakadda. Waa qalab koronto oo caadi ah oo ka jira nidaamyada korontada ee PoE. Si kastaba ha ahaatee, haddii shiduhu aanu lahayn shaqada POE, waxaa lagu dari karaa ...

Module-ka indhaha, gaar ahaan waxa uu tilmaamayaa moduleka indhaha ee baakadaysan ee yar-yar ee la isku beddeli karo. Waa moduleka indhaha oo si kulul loo kala beddeli karo inta lagu jiro hawlgalka oo loo isticmaali karo dekedda qalabka. Inta badan waxaa loo adeegsadaa in lagu xidho aaladda (guud ahaan waxa ay la jeedaan dabaylaha...

CWDM/DWDM kala qaybinta mawjadaha isku dhufashada isticmaalka qalabka Maaddaama shuruudaha dadku u baahan yihiin xajmiyeedku ay sare u sii kacayaan iyo sare u kacayaan, Qalabka Wavelength Division Multiplexing (DWDM) ayaa horumar weyn ka sameeyay dhimista kharashaadka, sidaas darteedna aad iyo aad ayey u f...

Dhismaha shabakadaha aagga magaalo-madaxda (gaar ahaan masaafada dheer ee OTN shabakadaha gudbinta indhaha), qaybinta dhererka dhererka qalabka isku dhufashada ayaa si gaar ah muhiim u ah. Qalabka isku dhufashada mawjada dhererka cufan ee DWDM wuxuu leeyahay masaafo dheer, sare-...

Shaqada ugu weyn ee beddelaha 485 waa inuu u beddelo calaamadda RS-232 ee hal-dhammaad ah oo loo beddelo calaamad RS-485 ama RS-422 ah oo dheellitiran. Sababo la xiriira gudbinta macluumaadka fog-fog iyo awood xoog leh oo ka-hortagga faragelinta, beddelayaasha rs485 ayaa si weyn loogu isticmaalaa sek ...
