Ukulungisa iingxaki kwi-DDM engaqhelekanga kwiimodyuli zamehlo
Xa ujongano lwemodyuli efakiweyo yokubona isilele ukusebenza kakuhle, ungalungisa ingxaki ngokwezi ndlela zintathu zilandelayo: 1) Jonga ulwazi lweAlarm yemodyuli yokubona. Ngolwazi lwe-alam, ukuba kukho ingxaki ngolwamkelo, ngokuqhelekileyo lubangelwa...Funda ngokugqithisileyo - Ngu Admin / 18 Jul 22 /0Amagqabantshintshi
Uvavanyo lwamandla okukhanya
Ixabiso lamandla okukhanya liya kuba nefuthe elibonakalayo kunye necacileyo kwisignali ngexesha lokuhanjiswa kwenkqubo, kwaye le mandla optical nayo ilula ukuvavanya. Eli xabiso linokuvavanywa ngamandla optical. Amandla okukhanya - sebenzisa imitha yamandla okukhanya ukuvavanya ukuba...Funda ngokugqithisileyo - NguMlawuli / 16 Jul 22 /0Amagqabantshintshi
Ukuvavanya iiparamitha zeemodyuli ze-optical
Ekusebenziseni ukusetyenziswa kweemodyuli ze-optical, akunakuphepheka ukuhlangabezana neengxaki ezahlukeneyo. Ukuze kuncitshiswe ingxaki yokungaphumeleli, kodwa nokukhusela uzinzo lwemodyuli ye-optical ngokusebenzisa. Kuya kubakho imisebenzi yobhaqo eyahlukeneyo yeemodyuli ezibonakalayo. Imodyuli ye-1X9 yeyona nto iphambili...Funda ngokugqithisileyo - Ngu Admin / 15 Jul 22 /0Amagqabantshintshi
IModyuli ye-Optical Output yamandla okukhanya
Imveliso ye-optical power (Amandla okuPhuma) ibhekiselele kumyinge wemveliso ye-optical power yomthombo wokukhanya ekupheleni kokuthumela imodyuli ye-optical, ekwabizwa ngokuba yi-output optical power, enokuqondwa njengobunzulu bokukhanya. Ifomula: P(dBm)=10Log(P/1mW) Iyunithi nguW okanye mW okanye dBm. (...Funda ngokugqithisileyo - Ngu Admin / 14 Jul 22 /0Amagqabantshintshi
Ujongano lweFibre-optic yeemodyuli ezibonakalayo
Oku kubhekiselele kujongano lwemodyuli ye-optical kwintambo yefiber optic patch, enokuthi idityaniswe ngemowudi enye okanye intambo yefiber optic yemultimode. Oku kulandelayo kukuhlalutya oku ngokweendlela ezahlukeneyo zojongano. Okwangoku, olona nxibelelwano luphambili kwimarike zezi: MPO, LC, S...Funda ngokugqithisileyo - Ngu Admin / 13 Jul 22 /0Amagqabantshintshi
