Themodule dekedda copperwaa moduleka u beddelaya dekedda indhaha oo u beddelaya deked koronto.Shaqadeedu waa in ay calaamadaha indhaha u rogaan calaamadaha korantada, nooca is-dhexgalkiisuna waa RJ45.

Module-ka-korontadu waa moduleka taageera isdhaafsiga kulul, iyo noocyada xirmooyinka waxaa ka mid ah SFP, SFP +, GBIC, iwm. Qalabka dekedda korantada wuxuu leeyahay sifooyinka isticmaalka tamarta hoose, waxqabadka sare, iyo naqshadeynta cufan.Marka loo eego heerarka kala duwan ee modules-ka korantada, waxaa loo qaybin karaa 100M modules dekedda korantada, 1000M modules dekedda korantada, 10G korantada modules iyo modules korantada is-qabta, oo ay ku jiraan 10M modules dekedda korontada iyo 10G korantada modules waa inta badan la isticmaalo .

Qaybaha indhahawaa aaladaha indhaha oo gudbin kara oo heli kara calaamadaha analoogga.Shaqadu waa in loo beddelo calaamadda korantada ee isha isha ka dib marka la soo maro dhammaadka gudbinta ee moduleka indhaha, ka dibna loo beddelo signalka indhaha ee signalka korantada iyada oo loo marayo dhamaadka helitaanka si loo xaqiijiyo beddelka sawir-qaadista.Qaybaha indhaha waxa loo qaybin karaa SFP, SFP+, QSFP+ iyo QSFP28 iyadoo loo eegayo foomamka baakadaha kala duwan.

Kuwa soo socda ayaa ah faraqa u dhexeeya modules-ka dekedda korantada iyo modules-yada indhaha:

1. Interface waa ka duwan yahay: interface ee module dekedda korantada waa RJ45, halka interface ee module ah inta badan waa LC, iyo sidoo kale waxaa jira SC, MPO, iwm.

2. Isku-duubyo kala duwan: Qaybaha dekedaha korantada ayaa inta badan loo adeegsadaa Qaybta 5, Qaybta 6, Qaybta 6e ama Qaybta 7 fiilooyinka shabakadda, halka modules-yada indhaha guud ahaan loo adeegsado xidhiidhinta jumpers indhaha.

3. Halbeegyadu way kala duwan yihiin: moduleka dekedda korantada ma laha mawjada dhererka, laakiin moduleka indhaha ayaa leh (sida 850nm\1310nm\1550nm).

4. Qaybuhu way kala duwan yihiin: qaybaha moduleka dekedda korantada iyo muraayadda indhaha ayaa kala duwan, gaar ahaan qaybta korantada korantada ma laha qalabka asaasiga ah ee moduleka indhaha - laser.

5. Fogaanta gudbintu way ka duwan tahay: fogaanta gudbinta moduleka dekedda korantada waa mid gaaban, ugu fogaana waa 100m oo kaliya, masaafada gudbinta moduleka indhaha waxay gaari kartaa 100m ilaa 160km iyadoo loo eegayo nooca fiber-ka indhaha ee loo isticmaalo xiriirka waa.
