Wireless router;ONU;ONT;OLT;Sharaxaadda ereybixinta fiber optic transceiver

1. AP, router wireless,wuxuu ku kala qaadaa calaamadaha shabakada isagoo adeegsanaya lammaane qalloocan. Iyada oo la adeegsanaayo isku-dubarid AP, waxay u beddeshaa calaamadaha korantada ee calaamadaha raadiyaha oo ay dirto.

2. ONU (Cutubka Shabakadda indhaha)unugga shabakadda indhaha. Qalabka shabakada PON, PON waxay isticmaashaa hal fiber optic ah si ay ugu xirto OLT, ka dibna OLT wuxuu ku xiran yahay ONU. ONU waxay bixisaa xogta, IPTV (Interactive Internet Television), codka iyo adeegyada kale. Dekadda PON halkan waxa ay tilmaamaysaa dekedda ku taal OLT. Mid ka mid ah deked PON waxay u dhigantaa hal qayb-qaybiyaha indhaha. PON (Passive Optical Network) Shabakadda indhaha ee dadban. Dekadda PON guud ahaan waxa loola jeedaa dekedda hoose ee OLT waxayna ku xidhan tahay kala qaybiyaha indhaha. Dekedda sare ee ONU waxa kale oo loogu yeedhi karaa dekedda PON. Modem-ka indhaha waxa loola jeedaa modem-ka fiber optic-ga, iyo dhammaan qalabka beddelka isticmaale-dhammaadka fiber optic-ga waxa si wada jir ah loogu tilmaami karaa modem-muuqaalka. Wax-ka-beddeliddu waa in calaamadaha dhijitaalka ah loo beddelo calaamadaha analoogga ah ee lagu kala qaado khadadka taleefanka, iyo demodulation waa in calaamadaha analoogga loo beddelo calaamadaha dhijitaalka ah, oo si wadajir ah loogu yeero modem. Waxaan u isticmaalnaa khadadka taleefoonka si aan u gudbinno calaamadaha analoogga, halka PC-yadu ay gudbiyaan calaamadaha dhijitaalka ah. Sidaa darteed, marka aad internetka kula xiriirto khadka taleefanka, waa inaad isticmaashaa modem.

3. ONT (Cutubka neerfaha indhaha)qalabka shabakada indhaha, oo u dhiganta ONU. Waa aaladda shabakadda indhaha ee loo isticmaalo dhammaadka isticmaalaha. Farqiga u dhexeeya ayaa ah: ONT waa terminaalka shabakadda indhaha, oo si toos ah ugu yaal dhammaadka isticmaalaha, halka ONU ay tahay unugga shabakadda indhaha, waxaana laga yaabaa inay jiraan shabakado kale oo u dhexeeya isaga iyo isticmaalaha, sida Ethernet. Alaabta CeitaTech ee ONU/ONT waxaa loo isticmaali karaa sida alaabada ONU/ONT ama router ahaan. Hal badeeco ayaa leh isticmaalyo badan.

4. OLT (Terminalka khadka indhaha)Terminalka khadka indhaha, qalabka terminaalka ee loo isticmaalo in lagu xidho khadadka jirridda fiber indhaha. Functions: (1) U dir xogta Ethernet ONU (Cutubka Shabakadda indhaha) qaab baahinta ah, (2) Bilow oo koontarool habka kala duwan oo duub macluumaadka kala duwan, (3) U qoondee bandwidth ONU, taas oo ah, xakamaynta bilawga xogta dirida ONU. waqtiga bilawga iyo diritaanka cabbirka daaqada. Shabakad ku xidhan inta u dhaxaysa qalabka xafiiska dhexe (OLT) iyo qalabka adeegsadaha (ONU/ONT) iyada oo loo marayo shabakad qaybinta indhaha (ODN)

5. Opticaltransceiver fiberwaa unugga beddelka warbaahinta gudbinta ee Ethernet kaas oo isweydaarsada calaamadaha korantada ee masaafo-gaaban iyo calaamadaha indhaha ee fog-fog. Waxa kale oo loo yaqaan beddelaha korantada (photoelectric)Beddelka Fiberka) meelo badan. . Badeecada waxaa guud ahaan loo isticmaalaa goobaha shabakadaha ee fiilooyinka Ethernet-ka aysan dabooli karin iyo fiber indhaha waa in la isticmaalo si loo kordhiyo fogaanta gudbinta, waxaana badanaa la dhigaa codsiga lakabka gelitaanka ee shabakadaha magaalooyinka waaweyn; Caawinta in lagu xidho mayl-ka ugu dambeeya ee khadadka fiber optic-ga iyo shabakadaha aagga magaalo-madaxda iyo Shabakadda dibadda.
