Chopatsira cha 1550nm CATV + SAT-IF Internal Modulation CHIKWANGWANI Optical

Chotumizira chakunja chosinthidwa cha 1550nm ndiye chinthu chapamwamba kwambiri. Gwiritsani ntchito Narrow line width (Typ.=0.3MHz) ndi Low-noise DFB laser yochokera kunja ngati gwero; Gwiritsani ntchito high linear LiNbO3 external modulator ngati RF signal modulator, yokhala ndi CTB yapadera, CSO, dual high-frequency SBS threshold control, etc. ukadaulo wapakati; wopangidwira ma netiweki otumizira ma transmission akutali.

Chotumizira chakunja cha 1550 series external modulation optical transmitter ndi chinthu choyamba chomwe chimagwiritsidwa ntchito polumikizirana ma network broadband transmission systems ndi ma CATV optical transmission systems akuluakulu. Chimagwiritsidwa ntchito poyendetsa ma optical modulation, optical insertion, WDM, ndi ma network ena okhudzana ndi kukulitsa makina akuluakulu oyendetsera ma optical a 1550nm. Ndicho chida chachikulu cha RFTV radio network system kuti ikwaniritse Triple-play, FTTH, ndi 1550nm systems.

1. Makonzedwe ambiri kuti asinthidwe: Ma specifications osiyana bwino amatha kukwaniritsa zofunikira za ma network osiyanasiyana, ndi kutulutsa kamodzi ndi kutulutsa kawiri, ndipo mphamvu yotulutsa imatha kusankhidwa kuyambira 3dBm mpaka 10dBm.
2. Laser yogwira ntchito bwino kwambiri: Laser ya DFB yokhala ndi mzere wopapatiza komanso phokoso lochepa ngati gwero la kuwala ndi modulator yakunja ya LiNbO3 ndiyo modulator yakunja ya chizindikiro.
3. Dongosolo losasinthika: Dongosolo labwino kwambiri losasinthika, lokhala ndi CTB ndi CSO yabwino kwambiri pamene CNR ili pamwamba.
4. Dongosolo loletsa SBS: Dongosolo loletsa SBS lapamwamba kwambiri, lomwe SBS imasinthasintha mosalekeza, lingakhale loyenera pa zosowa zosiyanasiyana za netiweki yotumizira mauthenga.
5. Kuwongolera kwa AGC: Kuwongolera kowonjezera mphamvu (AGC) kuti zisunge kutulutsa kwa chizindikiro chokhazikika pamene ma RF olowera osiyanasiyana alowa.
6. Chitsimikizo cha magetsi awiriawiri: Chosungira chamagetsi awiriawiri chomangidwa mkati, kuthandizira pulagi yotentha *, chosinthira chokha.
7. Kuwongolera kutentha kokhazikika: Kuwongolera kutentha kwa chassis yokha; mafani anzeru kutentha kwa chikwamacho kufika pa 30 ℃ kumayamba kugwira ntchito.
8. Chiwonetsero ndi alamu: Chiwonetsero cha LCD, chokhala ndi kuwunika kwa laser, chiwonetsero cha digito, chenjezo la zolakwika, kasamalidwe ka netiweki, ndi ntchito zina; Pamene magawo ogwirira ntchito a laser asiyana ndi mtundu wololedwa womwe wakhazikitsidwa ndi pulogalamuyo, alamu idzafunsidwa.
9. Ntchito yonse yoyang'anira netiweki: Chida chodziwika bwino cha RJ45, chomwe chimathandizira SNMP, kasamalidwe ka netiweki yakutali ya kompyuta, komanso kusintha kwa AGC, SBS, OMI, ndi zina zotero, chingasinthenso mtundu ndi nambala yotsatizana yomwe ikuwonetsedwa pagawo lakutsogolo, kasamalidwe ka netiweki yakomweko, ndi kuyang'anira.
