Core thiab lub hauv paus ntsiab lus ntawm kev xeem ib puag ncig kev tsim kho:
1. Xyuas seb puas muaj lub hwj chim kho qhov muag
Feem ntau siv lub zog kho qhov muag los kuaj seb puas muaj lub zog kho qhov muag; Thiab lub zog kho qhov muag ntawm qee qhov ophthalmograms yog -2dbm, -3dbm, thiab lwm yam.
2. Seb lub moos yog qhov tseeb
Lub moos yog cov ntaub ntawv siv los qhia qhov muag daim ntawv qhia. Poob, poob lub xeev: muaj lub teeb liab hauv daim ntawv qhia qhov muag, tab sis nws tsis meej pem thiab fuzzy, thiab nws tsis tuaj yeem tsim.
3. Kev teeb tsa qhov muag daim ntawv qhia
Kev xaiv tus nqi kis tau tus mob; Lim xaiv; Zaub ntawm extinction ratio thiab lwm yam ntaub ntawv
4: Cov ntsiab lus
Lub teeb yog tswj nyob rau hauv ib tug tej yam ntau yam, input mus rau lub qhov muag daim ntawv qhia instrument, thiab lub moos ntawm lub teeb yog input rau lub qhov muag daim ntawv qhia instrument.
Test ib puag ncig simulation thiab xyaum:
Cov lus qhia saum toj no yog cov lus qhia txog kev tsim kho qhov chaw sim coj los ntawm Shenzhen HDV Phoeletron Technology LTD., thiab peb lub tuam txhab yog cov chaw tsim khoom tshwj xeeb ntawm optical network, cov khoom lag luam koom nrog.ONUseries (OLT ONU/ACONU/CATVONU/GPONONU/XPONONU). Optical module series (optical fiber ntau module / Ethernet optical fiber module / SFP optical module),OLTseries (OLTkhoom siv /OLT hloov/optical mivOLT), thiab lwm yam., Muaj ntau yam tshwj xeeb ntawm cov khoom sib txuas lus rau cov kev xav tau ntawm cov xwm txheej sib txawv rau kev txhawb nqa network, txais tos sab laj.
