Pakalipano, pali FBG, FB ndi DFB lasers, Pakati pawo, ma laser omwe amagwiritsidwa ntchito kwambiri ndi FP ndi DFB.
FBG: Fiber Bragg Grating.
FP: Fabry-Perot, Fabry-Perot Laser Diode
DFB: Laser Yogawira Mayankho, Mayankho Ogawa a Laser Diode
Kwa omwe amagwiritsidwa ntchito kwambiri FB ndi DFB.Laser ya DFB imachokera pa FP laser ndipo imagwiritsa ntchito chipangizo chojambulira chowala (chomwe chimakhala chofanana ndi kuwonjezera chipata chokhala ndi chotchinga kuti chitseke kuwala kwina ndikungodutsa kuwala kwa utali wataliwu), kuti chipangizocho chikhale ndi njira imodzi yokha yotulutsa nthawi yayitali. (nthawi zambiri zotuluka za single-mode).Pankhani ya sipekitiramu, idzatulutsa kuwala kwa wavelength mkati mwazosiyana, pakati pawo njira yapakati kwambiri ya kutalika kwa mafunde ndi apamwamba kwambiri, omwe amatchulidwanso izi).
Makhalidwe a chipangizo chamtunduwu ndi: mphamvu yayikulu yotulutsa kuwala, ngodya yaing'ono yosiyana, mawonekedwe opapatiza kwambiri, Kusinthasintha kwamtunduwu ndikokwera, komwe kuli koyenera kulumikizana mtunda wautali.Amagwiritsidwa ntchito kwambiri pamafunde a 1550nm, ndipo kuchuluka kwake kuli pamwamba pa 2.5G.
Zida za semiconductor ndi mawonekedwe a resonator a awiriwa ndi osiyana.Ma laser a DFB ndi okwera mtengo ndipo amagwiritsidwa ntchito kwambiri pama module a kuwala ndi mtunda wodutsa wopitilira 40km;pomwe ma laser a FP ndi otsika mtengo ndipo amagwiritsidwa ntchito ngati ma module owoneka bwino okhala ndi mtunda wosakwana 40km.Ogwiritsa ntchito amatha kusankha malinga ndi momwe zilili.Pakadali pano, mayankho okhwima kwambiri a kampani yathu ndi zida zowonera pogwiritsa ntchito njira ziwirizi.
Zomwe zili pamwambazi ndikuyambitsa mitundu ya laser ya SFP modules yobweretsedwa ndi Shenzhen Shenzhen HDV photoelectric Technology Co., Ltd. Zomwe zimapangidwa ndi chivundikiro cha kampani. Optical fiber modules, Ethernet modules, Optical fiber transceiver modules, optical fiber access modules, SSFP Optical modules,ndiSFP kuwala ulusi, etc. Zomwe zili pamwambazi zimatha kupereka chithandizo pazochitika zosiyanasiyana za intaneti.Gulu la akatswiri komanso lamphamvu la R&D litha kuthandiza makasitomala omwe ali ndi zovuta zaukadaulo, ndipo gulu loganiza bwino komanso laukadaulo litha kuthandiza makasitomala kupeza ntchito zapamwamba panthawi yokambirana zisanachitike komanso pambuyo popanga.Takulandirani kuLumikizanani nafe pafunso lamtundu uliwonse.
