1. Cov nqi sib piv
(1) PON module nqi:
Vim nws txoj kev nyuaj thiab kev sib koom ua ke siab, tus nqi ntawm PON modules kuj yog siab heev. Qhov no feem ntau yog vim tus nqi siab ntawm nws cov khoom siv hluav taws xob (xws li DFB thiab APD chips), uas suav nrog ntau feem ntawm cov modules. Tsis tas li ntawd, PON modules kuj tseem koom nrog lwm cov khoom siv hluav taws xob IC, cov khoom siv hauv tsev, thiab cov khoom lag luam tawm, uas yuav ua rau nws cov nqi nce ntxiv.
(2) SFP module nqi:
Hauv kev sib piv, tus nqi ntawm SFP modules kuj tsawg. Txawm hais tias nws tseem yuav tsum tau xa thiab txais cov chips (xws li FP thiab PIN chips), tus nqi ntawm cov chips no qis dua cov chips hauv PON modules. Tsis tas li ntawd, qib siab ntawm kev tsim qauv ntawm SFP modules kuj pab txo nws cov nqi.
2. Kev sib piv kev tu
(1) PON module txij nkawm:
Kev saib xyuas ntawm PON modules yog qhov nyuaj. Txij li thaum PON tes hauj lwm koom nrog ntau lub nodes thiab kev sib kis mus ntev, nws yog ib qho tsim nyog yuav tsum tsis tu ncua xyuas qhov kev sib kis zoo, lub zog, thiab cov xwm txheej ntawm cov khoom siv fiber ntau ntawm cov teeb liab kho qhov muag. Tsis tas li ntawd, PON modules kuj yuav tsum tau them sai sai rau tag nrho cov kev ua haujlwm ntawm lub network kom sai sai thiab daws teeb meem.
(2) SFP module txij nkawm:
Kev saib xyuas ntawm SFP modules yog qhov yooj yim. Vim nws cov qauv tsim thiab kub-swappable muaj nuj nqi, kev hloov thiab kho ntawm SFP modules kuj yooj yim. Nyob rau tib lub sijhawm, tus qauv kev sib txuas ntawm SFP modules kuj txo qhov nyuaj ntawm kev saib xyuas. Txawm li cas los xij, nws tseem yuav tsum tau ua kom huv si tsis tu ncua ntawm qhov kho qhov muag module interface thiab fiber ntau txuas kom ntseeg tau tias lawv qhov chaw tsis muaj plua plav thiab av kom tswj tau qhov zoo thiab ruaj khov ntawm cov teeb liab kho qhov muag.
Hauv cov ntsiab lus, tus nqi ntawm PON modules yog qhov siab thiab kev saib xyuas yog qhov nyuaj; thaum tus nqi ntawm SFP modules kuj qis thiab kev saib xyuas yog qhov yooj yim. Rau qhov loj thiab nyuaj network ib puag ncig, PON modules yuav tsim nyog dua; thaum lub sijhawm uas xav tau kev teeb tsa sai thiab hloov pauv, SFP modules yuav tsim nyog dua. Nyob rau tib lub sijhawm, tsis hais qhov twg optical module siv, kev tu thiab tu ua haujlwm yuav tsum tau ua kom ntseeg tau tias kev ua haujlwm ruaj khov ntawm lub network.
