I le taimi nei, o loʻo i ai FBG, FB ma DFB lasers, Faatasi ai ma i latou, o le sili ona faʻaaogaina lasers o FP ma DFB.
FBG: Fiber Bragg Grating.
FP: Fabry-Perot, Fabry-Perot Laser Diode
DFB: Faʻasalalau Faʻamatalaga Laser, Faʻasalalau Faʻamatalaga Laser Diode
Mo le fa'aoga masani e masani ona fa'aoga FB ma DFB.O le DFB laser e faʻavae i luga o le FP laser ma faʻaaogaina se masini faamama mama (lea e tutusa ma le faʻaopopoina o se faitotoʻa ma se matala e poloka ai le isi moli ma naʻo le pasi atu o le malamalama o lenei galu umi), ina ia na o le tasi le faʻaogaina o le faʻaogaina o le auala umi. (e masani lava e tasi le faiga o galuega faatino).E tusa ai ma alaleo, o le a faʻaalia ai le umi o le galu i totonu o se laina, lea e sili ona maualuga le umi o le galu umi, lea e faʻaigoaina foi i lenei mea).
O uiga o lenei ituaiga masini e: tele le gaosiga o le mana opitika, laʻititi laʻititi laʻititi, vaapiapi tele alaleo, Ole fua faʻatatau e maualuga, lea e talafeagai mo fesoʻotaʻiga mamao.E masani ona faʻaaogaina i luga ole galu ole 1550nm, ma o le fua faatatau e sili atu ile 2.5G.
E ese'ese mea e fa'aogaina ai le semiconductor ma le resonator structure o ia mea e lua.DFB lasers e taugata ma e masani ona faʻaaogaina mo masini faʻapipiʻi ma se mamao faʻasalalau e sili atu i le 40km;a'o FP lasers e taugofie ma masani ona fa'aoga mo masini fa'apipi'i ma se mamao fa'asalalau e itiiti ifo i le 40km.E mafai e tagata faʻaoga ona filifili e tusa ai ma le tulaga moni.I le taimi nei, o fofo sili ona matutua a la matou kamupani o masini faʻaogaina e faʻaaogaina nei fofo e lua.
O loʻo i luga o le faʻalauiloaina lea o ituaiga leisa o SFP modules na aumai e Shenzhen Shenzhen HDV photoelectric Technology Co., Ltd. O oloa faʻapipiʻi na gaosia e le kamupani faʻapipiʻi. fa'apipi'i alava mata, Ethernet modules, opitika fiber transceiver modules, fa'aoga fa'aoga alava mata, SSFP mea fa'apipi'i mata, maSFP alava mata, ma isi mea. O oloa o lo'o i luga e mafai ona maua ai le lagolago mo fa'asologa o feso'otaiga eseese.E mafai e se 'au R&D fa'apolofesa ma malosi ona fesoasoani i tagata fa'atau i mataupu fa'apitoa, ma e mafai e se 'au pisinisi mafaufau ma fa'apolofesa ona fesoasoani i tagata fa'atau e maua ni 'au'aunaga sili ona lelei i le taimi a'o le'i fa'atalanoaina ma galuega pe a mae'a le gaosiga.Fa'afeiloa'i oe ifaafesootai matou mo so'o se ituaiga su'esu'ega.
