Okwangoku, kukho iilaser zeFBG, FB kunye neDFB, Phakathi kwazo, ezona lasers zisetyenziswa ngokuqhelekileyo yiFP kunye neDFB.
FBG: IFayibha Bragg Grating.
FP: Fabry-Perot, Fabry-Perot Laser Diode
I-DFB: ILaser yeeNgxelo ezisasaziweyo, iMpendulo eSasaziweyo yeLaser Diode
Kwi-FB esetyenziswa ngokuqhelekileyo kunye ne-DFB. I-laser ye-DFB isekelwe kwi-laser ye-FP kwaye isebenzisa isixhobo sokucoca ukukhanya (elingana nokongeza isango elinesilayidi ukuvala ukukhanya okunye kunye nokugqithisa ukukhanya kobu bude bobude), ukuze isixhobo sibe nemveliso enye yendlela yobude. (ngokubanzi imveliso yendlela enye). Ngokubhekiselele kwi-spectrum, iya kukhupha ukukhanya kwe-wavelength ngaphakathi koluhlu, phakathi kwayo eyona mowudi yobude bobude obusembindini iyeyona iphezulu, ethiywe ngale nto).
Iimpawu zolu hlobo lwesixhobo zezi: imveliso enkulu yamandla optical, i-angle yokuhlukana encinci, i-spectrum emxinwa kakhulu, isantya sokumodareyitha siphezulu, esilungele unxibelelwano lomgama omde. Isetyenziswa kakhulu kwi-wavelength ye-1550nm, kwaye izinga lingaphezulu kwe-2.5G.
Izixhobo ze-semiconductor kunye nesakhiwo se-resonator yezi zibini zihluke. Iilaser zeDFB zibiza kakhulu kwaye zisetyenziswa kakhulu kwiimodyuli zamehlo ezinomgama wothumelo ongaphezulu kwama-40km; ngelixa ii-laser ze-FP zitshiphu kwaye zisetyenziswa ngokubanzi kwiimodyuli zamehlo ezinomgama wokuhambisa ongaphantsi kwe-40km. Abasebenzisi banokukhetha ngokweyona meko. Okwangoku, ezona zisombululo zivuthiweyo zenkampani yethu zizixhobo zamehlo ezisebenzisa ezi zisombululo zibini.
Oku ngasentla kukuqaliswa kweentlobo ze-laser zeemodyuli ze-SFP eziziswa ngu-Shenzhen Shenzhen HDV photoelectric Technology Co., Ltd. Iimveliso zemodyuli eziveliswe yikhava yenkampani. iimodyuli zefiber optical, Iimodyuli ze-Ethernet, iimodyuli ze-fiber optical transceiver, iimodyuli zokufikelela kwifiber optical, Iimodyuli ze-SSFP ezibonakalayo, kwayeI-SFP optical fibers, njl. Ezi mveliso zemodyuli zingentla zinokubonelela ngenkxaso yeemeko ezahlukeneyo zenethiwekhi. Iqela le-R&D elinobuchule kunye nelomeleleyo linokunceda abathengi abanemiba yobugcisa, kwaye iqela leshishini elicingayo nelinobuchule linokunceda abathengi bafumane iinkonzo ezikumgangatho ophezulu ngexesha lokubonisana kwangaphambili kunye nomsebenzi wasemva kokuvelisa. Wamkelekile kuweQhagamshelana nathi kulo naluphi na uhlobo lombuzo.
