Iimodyuli yokubonai-accessory engundoqo yenkqubo yonxibelelwano lwe-optical kwaye idlala indima ebalulekileyo kunxibelelwano lwefiber optical.Ikakhulu igqibezela umsebenzi wokuguqula umbane.Umgangatho wemodyuli ye-optical inquma umgangatho wokuhanjiswa kwenethiwekhi ye-optical network.Iimodyuli ze-optical eziphantsi ziya kuba neengxaki ezifana nokulahlekelwa kwepakethi, ukuhanjiswa okungazinzanga, kunye nokunciphisa i-optical attenuation.Njengoko sonke siyazi, xa kuthelekiswa neemodyuli zangaphambili zamehlo, ixabiso leemodyuli ezihambelanayo ezibonakalayo liphantsi kakhulu.Emva koko ukhethe ngawaphi amanyathelo okhuseleko kwiimodyuli ezihambelanayo zamehlo?

1.Iisixhobo semodyuli yokubonaizakuguqulelwa ngokuntsonkothileyo kumgama othile ukuze ihambelane nesixhobo sayo.Abavelisi ababandakanyayo kufuneka benze ukulingana okubandakanyayo okwahlukileyo kwimodyuli ye-optical ukusombulula ngokugqibeleleyo ingxaki ehambelanayo.

2. Ubomi benkonzo: Ubomi benkonzo yemodyuli eqhelekileyo ye-optical yiminyaka emi-5, kuxhomekeke ekusebenziseni imodyuli ye-optical ngokwemiqathango yexesha, ukuba kukho ingxaki malunga ne-1 okanye iminyaka emi-2, ngoko kunokugwetywa ngokucacileyo ukuba Umgangatho wemodyuli ngokwayo unengxaki Okanye imodyuli esetyenzisiweyo.

3. Ukusebenza kwemodyuli ye-Optical: Iimpawu zokusebenza ezichaphazela imodyuli ye-optical ikakhulu ziquka i-avareji yamandla e-optical transmitted, i-extinction ratio, i-optical signal center wavelength, i-overload optical power, ukufumana i-sensitivity, kunye nokufumana amandla optical.Ngokubona ukuba ezi xabiso zingaphakathi koluhlu oluqhelekileyo Ukusebenza kwemodyuli ye-optical kunokugwetywa.Inokujongwa ngolwazi lweDDM.Ukongezelela, kunokugwetywa nokuba uphawu lwemodyuli ye-optical luzinzile ngexesha lokudluliselwa, nokuba kukho ukulibaziseka, nokuba kukho ukulahleka kwepakethi.

4. Nokuba yimodyuli yesibini-isandla: Xa uthenga imodyuli ehambelanayo ye-optical, kufuneka uqaphele ukuba ungalandeli ngokumfamekileyo amaxabiso aphantsi.Iimodyuli zesandla sesibini zihlala zineengxaki ezahlukeneyo kamsinya nje emva kokuba zisetyenzisiwe.
