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 yi-W okanye mW okanye i-dBm. (Apho i-W okanye i-mW iyiyunithi yomgca kunye ne-dBm iyunithi ye-logarithmic.) Kunxibelelwano, ngokuqhelekileyo sisebenzisa i-dBm ukubonisa amandla okukhanya.
Okukhona likhulu ixabiso lamandla okukhanya, kokukhona ukuqina kwamandla okukhutshwa kwamandla okukhanya. Kodwa oko akuthethi ukuba phezulu amandla optical, ngcono. Isixhobo ngasinye se-optical sinamandla optical asisigxina, kwaye amandla optical agqithisileyo aya kwandisa iimpazamo ezincinci. Ngokuqhelekileyo, amandla okukhanya kwimodyuli ye-SFP iphakathi kwe-2 kunye ne-13dbm, kwaye uluhlu lwexabiso luya kutshintsha kwakhona ngeekhilomitha zokuhambisa.
Kukho amandla optical ogqithisiweyo, kwaye kukho uvakalelo (ubuncinci bexabiso lonxibelelwano lwamandla okukhanya). Xa amandla optical adlulisiweyo amancinci kakhulu, amandla optical afunyenweyo ekupheleni kokufumana imodyuli aya kuba ngaphantsi kokufumana uvakalelo lwemodyuli, kwaye imodyuli ayikwazi ukufumana ukukhanya kwesignali ngokuqhelekileyo.
Xa amandla e-optical adlulisiweyo ekhulu kakhulu, nangona i-attenuator inokongezwa ekupheleni kokufumana ukufezekisa uluhlu lwamandla okufumana imodyuli yokufumana isiphelo, i-bias yangoku efunekayo iya kuba nkulu kakhulu, eya kuchaphazela umgangatho wokuhanjiswa kwesignali kunye. ubomi benkonzo yemodyuli.
Oku ngasentla kukuqaliswa kweentlobo ze-laser zeemodyuli ze-SFP eziziswa ngu-Shenzhen Shenzhen HDV photoelectric Technology Co., Ltd. iimveliso zemodyuli eziveliswe yikhava yenkampani.oiimodyuli zefiber yeptical, Iimodyuli ze-Ethernet, iimodyuli ze-fiber optical transceiver, iimodyuli zokufikelela kwifiber optical, Iimodyuli ze-SSFP ezibonakalayo, kwayeI-SFP optical fibers, njl.
Zonke ezi mveliso zemodyuli zingentla zinokubonelela ngenkxaso yeemeko ezahlukeneyo zenethiwekhi. Iqela le-R&D elinobuchule nelomeleleyo linokunceda abathengi abanemiba yobugcisa, kwaye iqela leshishini elicingayo nelinobuchule linokunceda abathengi bafumane iinkonzo ezikumgangatho ophezulu ngexesha lokubonisana kwangaphambili
kunye nomsebenzi wasemva kwemveliso. Wamkelekile kuwe Qhagamshelana nathi kulo naluphi na uhlobo lombuzo.
