Mphamvu yamagetsi yotulutsa (Output Power) imatanthawuza kuchuluka kwa mphamvu yamagetsi yamagetsi yomwe imatuluka kumapeto kwa gawo la optical, yomwe imatchedwanso mphamvu ya kuwala, yomwe imatha kumveka ngati mphamvu ya kuwala.
Fomula: P(dBm)=10Log(P/1mW)
Chipangizocho ndi W kapena mW kapena dBm. (Kumene W kapena mW ndi liniya unit ndipo dBm ndi logarithmic unit.) Polankhulana, nthawi zambiri timagwiritsa ntchito dBm kufotokoza mphamvu ya kuwala.
Kuchuluka kwa mphamvu ya kuwala, kumapangitsanso mphamvu ya mphamvu ya kuwala kwa magetsi. Koma sizikutanthauza kuti apamwamba kuwala mphamvu, bwino. Chida chilichonse chowoneka bwino chimakhala ndi mphamvu yamagetsi yochulukirapo, ndipo mphamvu yamagetsi yochulukirapo imawonjezera zolakwika pang'ono. Kawirikawiri, mphamvu ya kuwala ya SFP module ili pakati pa -2 ndi -13dbm, ndipo mtengo wamtengo wapatali udzasinthanso ndi makilomita opatsirana.
Pali mphamvu yamagetsi yochulukira, komanso palinso mphamvu (yochepa mphamvu yolumikizirana yamagetsi). Pamene mphamvu ya kuwala yopatsirana ndi yaying'ono kwambiri, mphamvu ya kuwala yomwe inalandira pamapeto a modules idzakhala yocheperapo kusiyana ndi kumvera kwa module, ndipo gawo silingalandire kuwala kwachizindikiro kawirikawiri.
Pamene mphamvu ya kuwala yopatsirana ndi yaikulu kwambiri, ngakhale kuti chowongoleracho chikhoza kuwonjezeredwa pamapeto olandira kuti akwaniritse mphamvu yolandira kuwala kwa gawo lolandira mapeto, zomwe zimafunikira panopa zidzakhalanso zazikulu kwambiri, zomwe zidzakhudza khalidwe la kufalitsa chizindikiro ndi moyo wautumiki wa module.
Zomwe zili pamwambazi ndikuyambitsa mitundu ya laser ya ma module a SFP obweretsedwa ndi Shenzhen Shenzhen HDV photoelectric Technology Co., Ltd.oPtical fiber modules, Ethernet modules, Optical fiber transceiver modules, optical fiber access modules, SSFP Optical modules,ndiSFP kuwala ulusi, ndi zina.
Zonse zomwe zili pamwambazi zimatha kupereka chithandizo pazochitika zosiyanasiyana za intaneti. Gulu laukadaulo komanso lamphamvu la R&D litha kuthandiza makasitomala pazinthu zaukadaulo, ndipo gulu loganiza bwino komanso laukadaulo litha kuthandiza makasitomala kupeza ntchito zapamwamba pakukambilana zisanachitike.
ndi ntchito pambuyo kupanga. Takulandirani ku Lumikizanani nafe pafunso lamtundu uliwonse.
