FAQ
Q1. FTTH optical receiver yog dab tsi?
A: FTTH optical receiver yog ib qho cuab yeej siv hauv fiber-to-the-home (FTTH) tes hauj lwm kom tau txais cov teeb liab kho qhov muag kis los ntawm cov kab hluav taws xob kho qhov muag thiab hloov mus rau hauv cov ntaub ntawv siv tau lossis cov teeb liab.
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. Nws lees txais triple-play optical input thiab tswj kev ruaj ntseg teeb liab los ntawm AGC. Nws hloov 1100-1620nm CATV teeb liab mus rau hluav taws xob RF tso zis rau cable programming.
Q3. Dab tsi yog qhov zoo ntawm kev siv FTTH optical receiver?
A: Qhov zoo ntawm kev siv FTTH optical receivers suav nrog lub peev xwm los txhawb kev xa tawm fiber ntau rau hauv tsev, uas tuaj yeem muab kev pabcuam siab Internet, TV thiab xov tooj ntawm ib leeg. Nws muab kev siv hluav taws xob tsawg, kev txais tos teeb liab ruaj khov thiab kev ua haujlwm siab photoelectric hloov dua siab tshiab rau CATV cov cim.
Q4. FTTH optical receiver puas tuaj yeem tuav cov wavelength sib txawv?
A: Yog lawm, FTTH optical receivers nrog WDM (Wavelength Division Multiplexing) muaj peev xwm ua tau ntau yam wavelengths, feem ntau ntawm 1100-1620nm, ua rau lawv tswj tau ntau yam CATV teeb liab kis tau los ntawm fiber ntau optic cables.
Q5. Dab tsi yog qhov tseem ceeb ntawm AGC thev naus laus zis hauv FTTH optical receiver?
A: Tsis siv neeg Gain Control (AGC) thev naus laus zis hauv FTTH optical receivers ua kom cov teeb liab ruaj khov los ntawm kev kho qhov muag pom lub zog kom tswj tau qib teeb liab zoo ib yam. Qhov no ua rau txhim khu kev qha, tsis muaj kev cuam tshuam kev sib kis ntawm CATV cov cim, ua kom muaj kev ua tau zoo tshaj plaws rau kev siv fiber ntau rau hauv tsev.
