Tam sim no, muaj FBG, FB thiab DFB lasers, Ntawm lawv, feem ntau siv lasers yog FP thiab DFB.
FBG: Fiber Bragg Grating.
FP: Fabry-Perot, Fabry-Perot Laser Diode
DFB: Distributed Feedback Laser, Distributed Feedback Laser Diode
Rau cov khoom siv feem ntau siv FB thiab DFB. Lub DFB laser yog raws li FP laser thiab siv lub teeb lim (uas yog sib npaug rau ntxiv lub rooj vag nrog ib tug slit los thaiv lwm lub teeb thiab tsuas kis lub teeb ntawm no wavelength), thiaj li hais tias tus ntaus ntawv tsuas muaj ib tug longitudinal hom tso zis (feem ntau ib hom tso zis). Nyob rau hauv cov nqe lus ntawm spectrum, nws yuav tso zis wavelength lub teeb nyob rau hauv ib tug ntau yam, cov uas feem ntau nruab nrab wavelength longitudinal hom yog siab tshaj, uas kuj muaj npe tom qab no).
Cov yam ntxwv ntawm cov cuab yeej no yog: cov khoom siv kho qhov muag loj loj, lub kaum sab xis me me, qhov nqaim tsis tshua muaj, qhov kev hloov kho tus nqi siab, uas yog tsim rau kev sib txuas lus ntev. Nws feem ntau yog siv rau ntawm lub wavelength ntawm 1550nm, thiab tus nqi siab tshaj 2.5G.
Cov ntaub ntawv semiconductor thiab resonator qauv ntawm ob yog txawv. DFB lasers yog kim thiab feem ntau yog siv rau kho qhov muag modules nrog ib tug kis nrug deb tshaj 40km; thaum FP lasers pheej yig thiab feem ntau yog siv rau optical modules nrog ib tug kis nrug deb ntawm tsawg tshaj li 40km. Cov neeg siv tuaj yeem xaiv raws li qhov xwm txheej tiag tiag. Tam sim no, cov kev daws teeb meem loj tshaj plaws ntawm peb lub tuam txhab yog cov khoom siv kho qhov muag siv ob txoj kev daws teeb meem no.
Cov saum toj no yog cov kev taw qhia ntawm laser hom SFP modules coj los ntawm Shenzhen Shenzhen HDV photoelectric Technology Co., Ltd. Cov khoom module tsim los ntawm lub tuam txhab npog optical fiber modules, Ethernet modules, optical fiber ntau transceiver modules, optical fiber nkag modules, SSFP optical modules, thiabSFP optical fibers, thiab lwm yam. Cov khoom lag luam saum toj no tuaj yeem muab kev txhawb nqa rau cov xwm txheej sib txawv. Ib pab neeg R & D muaj zog thiab muaj zog tuaj yeem pab cov neeg siv khoom nrog cov teeb meem kev lag luam, thiab pab pawg ua lag luam muaj kev xav thiab kev ua haujlwm tuaj yeem pab cov neeg siv khoom tau txais kev pabcuam zoo thaum lub sijhawm sib tham ua ntej thiab ua haujlwm tom qab tsim khoom. Zoo siab txais tos kojtiv tauj peb rau txhua yam kev nug.
