Waxaa laga yaabaa inaadan garanayn waxa "PON" yahay (badanaa loo akhriyo "pang"), laakiin waa inaad maqashay "fiber to the home".
Waxa laga yaabaa inaadan garanayn"ONU" waa (sida caadiga ah akhri"ONU"), laakiin markaad furto sanduuqa korontada ee daciifka ah ee gurigaaga, waa inaad aragto "sanduuqa yar" oo leh fiber optic ah. Tani "sanduuqa yar" waa kanONU(Cutubka Shabakadda indhaha, unugga shabakadda indhaha), oo loo yaqaanno “ONU“. Halyeeyga maanta —— “PON” (Passive Optical Network, Shabakadda indhaha ee dadban), waa furaha lagu gaaro helitaanka fiber indhaha, waa “kiiloomitirka ugu dambeeya” tignoolajiyada gudbinta fiber indhaha ee u dhexeeya shabakadda iyo isticmaalayaasha.
Wkoofiyadda waa PON?
Fiber indhaha qoys kasta, oo ku xidhan shabakad aad u weyn, aynu raacno fiber-ka indhaha, aynu raad raacno qulqulka, aynu wada baadho. Fiber indhaha ee ku xiranONUWaxay ka timaadaa kala qaybiyaha ceelka korontada daciifka ah, kaas oo u qaybin kara calaamada indhaha qaybo badan oo qayb ahaan. Calaamadaha indhaha ee galaya kala qaybiyaha indhaha waxa ay ka imanayaan terminalka khadka indhahaOLT(Terminalka khadka indhaha). TheOLT, ONU, iyo inta u dhaxaysa labada "kanaalka gudbinta" ODN (Shabakadda Qaybinta indhaha, shabakada qaybinta indhaha) waxay ka kooban tahay shabakadda PON. Waxaa ka mid ah:
OLTwaa aalad dhinaca wada shaqaynta mas'uul ka ah u wareejinta xogta shabakada ganacsiga ee heerka sare.
ONUwaa aalad dhinaca adeegsadaha mas'uul ka ah helitaanka xogta uu soo diroOLToo si toos ah u isticmaala.
Waxaan heli karnaa faham kooban oo ku saabsan qaab dhismeedka shabakadda PON sida ku cad sawirka hoose.
Shenzhen HDV Photoelectron Technology Ltd. waa xirfadleONUsoo saaraha qalabka sidoo kale waa isgaarsiin caqli lehONUiyo soo saaraha moduleka, shirkadeena hadda waxay iibisaa noocyo kala duwan oo ah qalabka isgaadhsiinta ee sare iyo hoose, sida: Beddelaha warbaahinta Fiber, Ethernetbeddelo, OLTqalabka,ONUqalab iyo wixi la mida. Haddii aad rabto inaad wax badan ka ogaato tignoolajiyada isgaarsiinta, ku soo dhawoow inaad nala soo xiriirto wakhti kasta.
