Tam sim no, optical fiber routing tiv thaiv tshuab feem ntau suav nrog kho qhov muag rov qab seem kev tiv thaiv, kho qhov muag kho lub nplhaib tiv thaiv thiab kho qhov muag fiber kab tsis siv neeg tiv thaiv (OLP) technology. Among them, the protection of the light recovery segment is for the whole process of the light recovery segment, but not for each optical circuit (such as end station to OA station and OA station to OA station). Moreover, because 1+1 protection is generally adopted, the insertion loss is relatively large (>5 dB). Kev tiv thaiv ntawm optical self-kho lub nplhaib yuav tsum muaj tag nrho cov khoom siv network tsim lub nplhaib. Thaum lub lag luam nyob rau hauv ib qho kev taw qhia raug thaiv, lub lag luam yuav lem mus rau lub hom phiaj ntawm qhov opposite direction. Qhov tsis zoo ntawm cov tswv yim no yog tias lub network yuav tsum tau khaws cia cov bandwidth xav tau los ntawm kev lag luam kev lag luam, uas ua rau muaj kev nqis peev ntau.
Kev tiv thaiv tsis siv neeg thev naus laus zis ntawm optical fiber kab yog kev daws teeb meem yooj yim thiab ua tau nrog kev ua haujlwm txhim khu kev qha. Nws tuaj yeem ua tiav qhov kev tiv thaiv kev hloov pauv los ntawm txoj hauv kev tseem ceeb mus rau txoj kev standby hauv 30ms, uas tuaj yeem tiv thaiv kev cuam tshuam ntawm optical cable tshwm sim los ntawm kev tsim kho hauv nroog thiab lwm yam haujlwm, thiab tom qab ntawd ua rau muaj kev cuam tshuam hauv network.
Cov keyboards kho qhov muag ntawm ob qho kawg yog txuas nrog ob txoj kab hluav taws xob kho qhov muag ntawm txoj kev sib txawv los ntawm kev hloov kho qhov muag ntawm ob qho kawg. Nyob rau hauv ib txwm muaj xwm txheej, optical keyboards ntawm ob qho kawg yog xaiv los ua kab tseem ceeb. Lub caij no, OLP cov cuab yeej tuaj yeem saib xyuas cov kab standby hauv lub sijhawm tiag tiag, thiab xa lub tswb raws sijhawm yog tias muaj qhov xwm txheej txawv txav, ceeb toom tus tswv kom kho sai li sai tau, txhawm rau xyuas kom meej tias cov kab standby muaj nyob. Txawm li cas los xij, thaum lub ntsiab fiber ntau optic cable tsis ua hauj lwm nce dhau qhov kev hloov pauv, qhov hloov kho qhov muag ntawm ob qho kawg yuav raug hloov mus rau txoj kab standby kom ntseeg tau tias kev ua haujlwm ntawm lub cev.
CovOLP ntaus ntawvmuaj kev tswj hwm kev ywj pheej, uas tuaj yeem saib xyuas qhov txo qis ntawm cov kab hluav taws xob kho qhov muag, lub zog luminous thiab lub zog luminous ntawm lub cuab yeej hauv lub sijhawm tiag tiag thiab intuitively. Tsis tas li ntawd, tus thawj coj hauv lub network tseem muaj lub luag haujlwm ntawm cov lus luv luv miv, uas tuaj yeem qhia cov neeg ua haujlwm raws sijhawm ntawm cov ntaub ntawv ceeb toom tshwj xeeb raws li cov neeg siv khoom xav tau. Txij li thaum OLP tau txais kev hloov kho qhov muag ntawm ob qho kawg kom paub txog qhov kev xaiv, qhov kev cuam tshuam poob ntawm thawj kab yog qhov tsawg, feem ntau qis dua 3dB, thiab kev cuam tshuam poob ntawm qhov zoo tshaj OLP tuaj yeem ncav cuag tsawg dua 1dB. Raws li cov ntaub ntawv chav kis tau tus mob nyob deb tsis deb, qhov nce poob yuav tsis cuam tshuam rau kev ua haujlwm ntawm lub cev. Tsis tas li ntawd, txij li lub hauv paus hloov pauv yog qhov txo qis ntawm cov kab hluav taws xob kho qhov muag, nws tsis muaj dab tsi cuam tshuam nrog cov chaw tsim khoom thiab qhov system ceev.
Ntxiv mus, cov cuab yeej siv tau sib xws nrog txhua lub tuam txhab tsim khoom thiab tuaj yeem ua tau raws li qhov xav tau ntawm ntau lub tshuab nrog tus nqi sib txawv. Piv txwv li, SDH/PTN thiabDWDM/OTNtuaj yeem tiv thaiv, thiab GE thiab 10G kev tiv thaiv kuj tuaj yeem siv rau 40G thiab 100G kev tiv thaiv. Qhov no txhais tau hais tias thaum cov khoom siv ntawm ob qho kawg tau hloov kho dua tshiab, OLP cov cuab yeej tsis tas yuav hloov kho, tab sis tsuas yog yuav tsum tau kho qhov cuam tshuam raws li cov kab ke sib txawv.
