FAQ
FTTH Optical Receiver Cov lus nug nquag
Q1. FTTH optical receiver yog dab tsi?
A: Ib qho FTTH optical receiver yog ib qho khoom siv hauv fiber-to-the-home (FTTH) tes hauj lwm. Nws yog tsim los kom tau txais cov teeb liab kho qhov muag los ntawm fiber ntau optic tes hauj lwm thiab hloov mus rau hauv cov teeb liab hluav taws xob rau kev ua haujlwm ntxiv.
Q2. FTTH optical receiver ua haujlwm li cas?
A: FTTH optical receiver txais kev txais hluav taws xob qis thiab kho qhov muag tsis siv neeg nce (AGC) thev naus laus zis. AGC thev naus laus zis ua kom ntseeg tau tias lub zog kho qhov muag tau txais nyob rau hauv ib qho tshwj xeeb los ntawm kev kho qhov nce ntawm tus txais. Qhov no ua kom ntseeg tau cov teeb liab txais tos thiab kev ua haujlwm zoo tshaj plaws.
Q3. Dab tsi yog cov txiaj ntsig ntawm kev siv FTTH optical receiver?
A: Siv FTTH optical receivers coj ntau qhov zoo rau FTTH tes hauj lwm. Nws ua kom muaj txiaj ntsig zoo ntawm fiber ntau optic teeb liab txais tos thiab hloov dua siab tshiab, ua kom muaj kev kub ceev Internet, zoo tshaj plaws digital TV, thiab cov kev pab cuam lub suab meej. Tsis tas li ntawd, nws tuaj yeem ua ke nrog Optical Network Unit (ONU) lossis Ethernet dhau Coax (EOC) rau kev pabcuam triple-play.
Q4. Dab tsi yog daim ntawv thov ntawm FTTH optical receivers?
A: FTTH optical receivers feem ntau yog siv hauv FTTH tes hauj lwm los txuas cov tsev nyob lossis chaw lag luam nrog fiber ntau optic infrastructure. Nws ua raws li cov khoom siv kawg uas siv cov teeb liab kho qhov muag mus los ntawm fiber ntau optic cables thiab hloov mus rau cov teeb liab hluav taws xob tsim nyog rau ntau yam kev pabcuam, suav nrog Is Taws Nem, TV, thiab lub suab.
Q5. FTTH optical receiver puas siv tau nrog lwm yam khoom siv?
A: Yog, FTTH optical receiver tuaj yeem siv ua ke nrog ONU lossis EOC kom paub txog kev ua si triple. ONU ua lub hauv paus rau kev faib tawm Is Taws Nem, TV thiab lub suab teeb liab hauv thaj chaw, thaum FTTH optical receivers ua kom ntseeg tau txais kev txais tos thiab hloov cov teeb liab no.
