Thaum peb tham txog FTTHUa ntej, peb yuav tsum tham txog kev nkag mus rau fiber optic. Kev nkag mus rau fiber optic txhais tau tias fiber optic yog siv ua qhov nruab nrab ntawm chaw ua haujlwm hauv nruab nrab thiab tus neeg siv. Kev nkag mus rau fiber optic tuaj yeem muab faib ua kev nkag mus rau active optical thiab passive optical. Lub hauv paus thev naus laus zis ntawm lub network fiber optic subscriber yog lub teeb nthwv dej kis thev naus laus zis. Multiplexing thev naus laus zis rau kev xa xov fiber optic tab tom txhim kho sai heev, thiab feem ntau ntawm nws twb siv tau lawm. Raws li qib ntawm kev nkag mus rau fiber ntawm cov neeg siv, nws tuaj yeem muab faib ua FTTC, FTTZ, FTTO, FTTF, FTTH, thiab lwm yam.
Fiber Mus Rau Lub Tsev (FTTH, tseem hu ua Fiber Mus Rau Lub Tsev) yog ib txoj kev xa kev sib txuas lus hla fiber optic cable. Nws txuas fiber optic cable ncaj qha mus rau lub tsev ntawm tus neeg siv (txhua qhov chaw uas tus neeg siv xav tau). Tshwj xeeb, FTTH hais txog kev teeb tsa Optical Network Units (ONUs) ntawm cov chaw nyob lossis chaw ua lag luam, thiab nws yog hom kev siv optical access network ze tshaj plaws rau tus neeg siv hauv cov koob optical access, tsis suav nrog FTTD (Fiber Mus Rau Lub Desktop). Lub ntsiab lus tseem ceeb ntawm FTTH yog tias nws tsis tsuas yog muab bandwidth siab dua tab sis kuj txhim kho kev pom tseeb ntawm network hauv cov ntaub ntawv hom ntawv, qhov ceev, wavelengths, thiab cov txheej txheem, so kom txaus rau ib puag ncig thiab kev xav tau hluav taws xob, thiab ua kom yooj yim rau kev saib xyuas thiab kev teeb tsa.
