Cov ntsiab lus ntawm BOSA:
Lub teeb emitting yog hu ua TOSA;
Qhov chaw txais lub teeb hu ua ROSA;
Thaum ob leeg tuaj ua ke, lawv hu ua BOSA.
Electric rau Optical TOSA:
LD (Laser Diode) semiconductor laser, siv los hloov cov teeb liab hluav taws xob rau hauv cov teeb liab kho qhov muag siv rau hauv cov khoom siv kho qhov muag
Optical rau Electric ROSA:
PD Photo Dioder photodiode, siv los hloov cov teeb liab teeb liab mus rau tam sim no, uas tom qab ntawd hloov mus rau hauv qhov hluav taws xob hluav taws xob los ntawm kev sib nrig sib impedance amplifier (TIA).
TOSA thiab ROSA tuaj yeem siv cais ua LC optical module thiab SC optical module. Thaum siv BOSA, nws feem ntau yog siv los ua SC optical module
Kev xaiv ntawm qhov loj me yog nyob ntawm qhov loj tam sim no thiab muaj cov kev paub hauv qab no:
Ib qhov 10mil nrog 20mil PAD sib raug rau qhov tam sim no ntawm 0.5A rau 20mil xaim, thiab 40mil qhov nrog 40mil PAD sib raug rau tam sim no ntawm 1A rau 40mil xaim. Thaum qhov kev thov tam sim no siab, ntau lub vias tuaj yeem muab tso rau hauv cov haujlwm uas nyob ib sab kom nce cov kabmob muaj peev xwm. Tus nqi drilling feem ntau suav txog 30% txog 40% ntawm PCB raug nqi.
Xav txog cov nqi thiab cov teeb liab zoo, nws yog qhov zoo dua los xaiv 10/20mil (drilling / soldering pad) rau 6-10 txheej boards. Rau siab ceev thiab me me PCBs, 8mil drilling tau sim. Qhov me me drilling loj ua rau nws nyuaj rau kev ua tiav cov txheej txheem, lub laum me ntsis yooj yim tawg, thiab tus nqi nce. Feem ntau, pawg thawj coj saib xyuas yuav tsum tau them tus nqi drilling kom tsawg dua 11.81mil.
Los ntawm kev tsim kev xav, ib qho los ntawm lub qhov muaj xws li nruab nrab qhov drilling qhov thiab qhov chaw nyob ib puag ncig cov ntaub qhwv, uas txiav txim siab qhov loj ntawm lub qhov drilling. Raws li qhov loj ntawm lub qhov los ntawm qhov me me, cov kab mob parasitic capacitance me dua, uas yog qhov zoo dua rau kev ruaj ntseg ntawm cov teeb liab ceev.
Nyob rau tib lub sijhawm, qhov loj ntawm qhov dhau los yog txwv los ntawm cov txheej txheem drilling thiab electroplating; Qhov me me ntawm lub qhov, lub sijhawm nws siv sijhawm ntev dua, thiab qhov yooj yim dua nws yog deviate los ntawm qhov chaw nruab nrab. Thaum lub qhov tob tob (los ntawm qhov tob ntawm 50mil) ntau tshaj 6 npaug ntawm qhov aperture, nws tsis tuaj yeem ua kom ntseeg tau tias cov tooj liab plating ntawm lub qhov phab ntsa. Yog li ntawd, qhov tsawg kawg nkaus drilling txoj kab uas hla uas PCB manufacturers muab tau yog 8mil.
Cov saum toj no yog cov ntsiab lus luv luv ntawm "Introduction to Key Parameters of BOSA - ntawm qhov loj me (I)", uas tuaj yeem ua tus siv rau txhua tus. Peb lub tuam txhab muaj ib pab neeg ua haujlwm muaj zog thiab tuaj yeem muab kev pabcuam tshaj lij rau cov neeg siv khoom. Tam sim no, peb lub tuam txhab muaj ntau yam khoom: ntseonu, kev sib txuas lus kho qhov muag module, optical fiber module, sfp optical module,olt uakhoom siv, Ethernethloovthiab lwm yam khoom siv network. Yog tias koj xav tau, koj tuaj yeem kawm paub ntxiv txog lawv.
