Yas Optical Fiber Txhim Kho Thiab Cov Cheebtsam Yooj Yim Thiab Yooj Yim Tsawg
Yas fiber kho qhov muag yog lub teeb, mos, thiab ntau tiv rau kev puas tsuaj (kev co thiab khoov). Cov yas fiber ntau muaj qhov ua tau zoo tensile lub zog, kav ntev thiab me me hneev taw. Cov kev zoo no ua rau daim ntawv thov zoo ntawm cov yas optical fiber ntau hauv cov tsheb tshwj xeeb. Lub tsheb tshwj xeeb tshaj plaws muaj tsawg kawg yog ob peb mais ntawm tooj liab xov tooj thiab cable sab hauv, uas zoo heev nce qhov nyhav thiab nqi. Qhov no muaj tseeb rau cov dav hlau, tsheb ciav hlau thiab txhua txoj kev thauj mus los.
Vim tias qhov loj ntawm txoj kab uas hla thiab cov lej siv ntawm cov yas kho qhov muag fiber ntau, lub teeb kis tau muaj peev xwm loj. Yas optical fiber muaj ntau dua bandwidth muaj peev xwm tshaj tooj liab kis xov xwm (sib ntswg thiab coaxial cable). Qhov ntau dua qhov kev sib kis, qhov qis dua tus nqi ntawm kev siv cov yas fiber ntau.
Kev txiav, xov hlau, ntawv cog lus, polishing thiab lwm cov txheej txheem ntawm cov yas kho qhov muag yog yooj yim. Vim tias qhov taub loj dua, yas kho qhov muag fiber ntau txuas thiab txuas nrog cov khoom siv, cov khoom siv hluav taws xob, cov khoom kuaj, thiab lwm yam dhau los ua qhov yooj yim thiab txo tus nqi, thiab cov kws tshaj lij kuj tseem tuaj yeem tsim cov haujlwm no. Nws siv sijhawm tsis pub dhau 1 feeb los npaj cov kev sib txuas ntawm cov yas kho qhov muag yas, thiab tsis tas yuav muaj cov cuab yeej tshwj xeeb. Txawm tias cov txiab yooj yim tshaj plaws tuaj yeem siv los txiav cov yas kho qhov muag. Cov yas optical fiber transceiver module siv lub teeb liab nrog lub suab yoj ntawm 650nm, uas muaj kev nyab xeeb heev, thiab cov neeg siv tau pom thiab yooj yim txiav txim siab seb puas muaj qhov sib txuas fiber ntau. Ntxiv rau, qhov kev sib txuas ntawm cov yas hluav taws xob zoo yog tsis rhiab plua plav thiab cov khib nyiab daig ntawm lub ntsej muag kawg.
Cov yas siv hluav taws xob tsis tsim hluav taws xob, thiab yog cov tiv thaiv hluav taws xob cuam tshuam, lub xov tooj cua cuam tshuam thiab suab nrov. Qhov no yog qhov tshwj xeeb tshaj plaws rau kev faib cov nkauj thiab audio. Pom tseeb, cov kev cuam tshuam thiab suab nrov no cuam tshuam rau cov duab thiab cov kev pabcuam zoo. Yas fiber ua hluav taws xob thiab tooj liab xov tooj tuaj yeem muab tso rau ib sab ntawm tib txoj hlua lossis tib qho hlua. Cov yas fiber ntau ua rau tsis muaj suab nrov thiab yuav tsis muaj qhov tsis zoo rau lub network tam sim no.
Tus nqi ntawm POF system yog tus nqi tsawg. Nws tau hais tias tus nqi ntawm txhua qhov kev sib txuas siv rau cov khoom siv hluav taws xob hauv tsev, sib txuas hauv tsev thiab tsheb nrog rau audio, DVD, VCR, thiab lwm yam yog tsawg dua 20 las. Yog li cov cuab yeej no tuaj yeem yuav tau yuav hauv khw hauv khw.
