Optical qhov muag duab debugging

Optical qhov muag duab debugging Lub Hom Phiaj:
Extinction ratio
Kev tshawb fawb thiab kev loj hlob theem: nyob nruab nrab ntawm 10-15 (loj yog zoo dua me me), raws li qhov tseeb qhov teeb meem yuav tsim nyog los txhim kho qhov extinction ratio, tab sis tsis tsawg heev. Nws muaj feem xyuam rau rhiab heev.
Quiver
Kev tshawb fawb thiab kev loj hlob theem: tswj tsis pub dhau 20PS. Qhov tsawg dua qhov zoo, qhov kev ua yuam kev zoo dua.
Hla taw tes
Kev tshawb fawb thiab kev loj hlob theem: 48% -55%. Nws yog qhov ntsuas ntawm lub sijhawm nyeem ntawv ntawm 0 thiab 1 qib. Kev sib txuas nrog cov zaus rho tawm yog qhov kev ua haujlwm ntawm kev ua haujlwm ntawm synchronization poob.
Optical zog
Kev tshawb fawb thiab kev loj hlob theem: Tswj ntawm -3dbm ~ -9dbm. Coj tus nqi nruab nrab kom deb li deb tau, thiab koj yuav tsum ntsuas qhov kev ploj tuag ntawm tus nqi no los ua qhov kev xaiv zoo tshaj plaws. Nws yog ib qho kev ntsuas ntawm lub teeb liab zog.
Optical qhov muag duab debugging - Txoj kev:
1. Tshaj tawm
Lub qhov muag duab qhia tau hais tias ib nrab sab saum toj protrusion; Txoj kev daws teeb meem yog los txhim kho qhov nce qib
2. Ua tsis taus pa
Daim ntawv qhia qhov muag qhia txog qhov qis qis qis qis; Kev daws los txhim kho qhov poob ntug
3. Hla cov ntsiab lus
Tus nqi no tuaj yeem nyeem ncaj qha los ntawm daim ntawv qhia qhov muag. Nws tuaj yeem sib phim los ntawm kev kho qhov voltage ntawm LD +, qhov voltage ntawm LD-, Imod tam sim no, thiab cov kab sib txawv impedance
4. Kev chim siab
Tus nqi no tuaj yeem nyeem ncaj qha los ntawm daim ntawv qhia qhov muag. Nws tuaj yeem sib phim los ntawm kev kho qhov voltage ntawm LD +, qhov voltage ntawm LD-, Imod tam sim no, thiab cov kab sib txawv impedance
Cov saum toj no yog Shenzhen HDV Phoelectron Technology Ltd. coj cov neeg siv khoom hais txog "optical eye map debugging" kab lus qhia, thiab peb lub tuam txhab yog cov chaw tsim khoom tshwj xeeb ntawm optical network manufacturers, cov khoom lag luam koom nrogONUseries (OLT ONU/ACONU/CATVONU/GPONONU/XPONONU), Optical module series (optical fiber module / Ethernet optical fiber module / SFP optical module),OLTseries (OLTkhoom siv /OLT hloov/optical mivOLT), thiab lwm yam., muaj ntau yam specifications ntawm kev sib txuas lus cov khoom rau cov kev xav tau ntawm txawv scenarios rau network txhawb, txais tos mus tham.
