Ngokuxhumana optical, ukuhlola amandla optical isinyathelo esibalulekile ekwakheni imvelo optical. Izinga lamandla okubona lithinta ukusebenza kwedivayisi eyamukelayo. Amandla okukhanya aphansi kakhulu azokwenza idivayisi ingakwazi ukukhonjwa, futhi amandla okukhanya aphezulu kakhulu azolimaza idivayisi ngokwayo. Ngakho-ke, kufanele sinake ukutholwa kwamandla optical.
Ukuze sithole amandla okukhanya, sidinga ukusebenzisa imitha yamandla okukhanya. Ngaphambi kokuthola amandla okubona edivayisini ezohlolwa, kufanele siqale siqinisekise ukuthi imitha yamandla okubona ijwayelekile. Uma inani lokubonisa lemitha yamandla okubona lingalungile, sidinga ukuyilinganisa futhi sivumele imitha yamandla okubonayo ukuthi ikhombe kunani elilungile. Ngalesi sizathu, sidinga nomthombo wokukhanya ojwayelekile.
Okulandelayo kuzokwethula izinyathelo zokulinganisa imitha yamandla okubona:
Ake siqale ngokucacisa umqondo ophusile. Umgomo omkhulu uwukuthola umthombo wokukhanya ojwayelekile, siyalazi inani lamandla okukhanya omthombo wokukhanya ojwayelekile, bese sixhuma ukukhanya kumitha yamandla okukhanya, silungise inani lokubonisa lemitha yamandla okukhanya, ukuze lilingane nenani langempela lamandla okukhanya esilaziyo. Hhayi-ke, inhloso iwukudinga umthombo wokukhanya owazi inani leqiniso lamandla okukhanya.
Sisebenzisa umthombo wokukhanya ojwayelekile wamadivayisi e-HP, bese sisebenzisa imitha yamandla okukhanya ejwayelekile ngaphakathi kwedivayisi (impela, kungase kube nabafundi ngalesi sikhathi, uma idivayisi yakho ingavunyelwe? Okokuqala, kufanele usule izinga lokuhambisana limelela inani elithile ukuvumelana kwabantu komphakathi wamazwe ngamazwe, lokhu kuyindinganiso, bese ucabanga ukuthi ngisebenzisa idivayisi akuvunyelwe ukuthi thatha idivayisi yakho encane enembile kuphela lapho umthombo wokukhanya owusebenzisile uhlola kuphela umthombo wokukhanya owusebenzisile ukuze uhlole. amazinga, lokhu akunangqondo, sicela ungabhola), ukufunda inani lamandla okukhanya, ungathola ukwazi inani lamandla okukhanya kwangempela lomthombo wokukhanya.
Nazi izinyathelo ezithile zokusebenza.
1. Setha umthombo wokukhanya ojwayelekile
Ngemva ebhuthini ukufinyelela interface elandelayo.
Cindezela inkinobho ethi “1″ (khetha Isilungiselelo) ukuze ufake isixhumi esibonakalayo esilandelayo.
Inkinobho ethi “1″ emfanekisweni ongenhla ihambisana nobude beza obumaphakathi bomthombo wokukhanya, enezinketho ezimbili: 1310nm kanye ne-1550nm;
Inkinobho ethi “2″ ehambisana nesikhathi kufanele ifanele imvamisa yokukhanya;
Inkinobho ethi “3″ ihambisana neyunithi, ungakhetha i-dBm noma amayunithi amabili ama-W;
Inkinobho ethi “4″ ihambisana nobude begagasi, futhi ivelu ye-wavelength ingashintshwa ngokufaka inombolo, okuwubude obumaphakathi obutholwa idivayisi.
Chofoza inkinobho ethi "instr" ukuze ubuyele kusixhumi esibonakalayo se-Power Meter, okuyisithombe sokuqala. Chofoza inkinobho ethi "Vula / Vala Umthombo" ukuze uvule okukhiphayo komthombo wokukhanya. Isibani esikhiphayo sedivayisi sixhunywe endaweni yokwamukela idivayisi, njengoba kuboniswe esithombeni esingezansi, futhi inani lamandla okubona lomthombo wamanje wokukhanya ojwayelekile ngu-7.799 dBm.
2. Lungisa imitha yamandla okukhanya
Dlulisela ukukhanya okukhiphayo kumitha yethu yamandla okukhanya, njengoba kuboniswe esithombeni esingezansi.
Thatha imitha yami yamandla okukhanya njengesibonelo, qala ukhethe ubude beza obuhambisanayo. Njengoba umthombo wokukhanya ungu-1310nm, khetha u-1310 lapha, cindezela u-“λ”, “UNIT” kanye “REF”, kanye no-“REF” ukuze ulungise i-amplitude phezulu naphansi iye ku-7.79 dBm okunamathiselwe; chofoza okuthishintshaukhiye ekhoneni eliphezulu kwesokunxele lemitha yamandla ukuze uphume kumodi yokulungisa iphutha.
Kulokhu ukulungiswa kwethu kwemitha yamandla okukhanya kuqediwe, okungukuthi i-Shenzhen HDV photoelectric technology co., LTD., ikuhlinzeka ngolwazi lokulinganisa imitha yamandla okukhanya. siyabonga ngokubuka, mayelana nemikhiqizo yethu yenethiwekhi ehlobene kanye nemishini, ehlanganisaI-ONUuchungechunge,OLTuchungechunge, i-transceiver, imojula ye-SFP, imojula ye-SFF, njll., yamukela wonke umuntu ukuze aqonde, siyavalelisa ngokuzayo
