1550nm kunja modulated Optical transmitter ndiye chinthu chapamwamba kwambiri. Pezani Mzere Wopapatiza (Mtundu.=0.3MHz) ndi Laser ya DFB yotulutsa phokoso Lochepa ngati gwero; Atengere mkulu liniya LiNbO3 modulator kunja monga RF chizindikiro modulator, ndi CTB wapadera, CSO, wapawiri mkulu-pafupipafupi SBS polowera kulamulira, etc. umisiri pachimake; zopangidwira ma netiweki otumizira mtunda wautali.
Makina a 1550 akunja opangira ma transmitter ndiye chinthu choyamba kusankha pamakina otumizira ma burodibandi ndi makina akulu akulu a CATV optical transmitter. Imagwiritsidwa ntchito pakusintha kwa mawonekedwe, kuyika kwa kuwala, WDM, ndi kukweza maukonde okhudzana ndi kukulitsa njira yayikulu yotumizira ma 1550nm. Ndizida zoyambira zamawayilesi a RFTV kuti azindikire machitidwe a Triple-play, FTTH, ndi 1550nm.
Mbali
1. Kukonzekera kosiyanasiyana kwa makonda: Mafotokozedwe osiyanitsa bwino amatha kukwaniritsa zofunikira za maukonde osiyanasiyana, ndi kutulutsa kamodzi ndi kutulutsa kawiri, ndipo mphamvu zotulutsa zotulutsa zimatha kusankhidwa kuchokera ku 3dBm mpaka 10dBm.
2. Laser yogwira ntchito kwambiri: Laser ya DFB yokhala ndi mzere wopapatiza komanso phokoso lochepa ngati gwero la kuwala ndi LiNbO3 kunja kwa modulator ndi chizindikiro chakunja.
3. Pre-distortion circuit: Superior pre-distortion circuit, ndi CTB yangwiro ndi CSO ntchito pamene CNR ili pamwamba.
4. SBS kupondereza dera: Superior SBS kupondereza dera, SBS mosalekeza chosinthika, akhoza kukhala oyenera kufala osiyana mtunda zofuna maukonde.
5. Ulamuliro wa AGC: Automatic gain control (AGC) kuti mukhalebe ndi chidziwitso chokhazikika pamene ma RF alowetsa zosiyana.
6. Chitsimikizo chamagetsi apawiri: Kusungirako mphamvu ziwiri zomangidwa, kuthandizira kutentha * pulagi, kusintha kosintha.
7. Kuwongolera kutentha kwathunthu: Kuwongolera kutentha kwa galimoto yamoto; mafani anzeru pamene kutentha kwa mlandu mpaka 30 ℃ kumayamba kuthamanga.
8. Kuwonetsa ndi alamu: Kuwonetsera kwa LCD, ndi kuyang'anira laser, kuwonetsera kwa digito, kuchenjeza zolakwika, kasamalidwe ka maukonde, ndi ntchito zina; Pamene magawo ogwirira ntchito a laser achoka pamtundu wovomerezeka wokhazikitsidwa ndi pulogalamuyo, alamu idzafunsidwa.
9. Ntchito yoyang'anira maukonde onse: Mawonekedwe a RJ45, amathandiza SNMP, kasamalidwe ka maukonde akutali kwa kompyuta, ndi kusintha kwa AGC, SBS, OMI, ndi zina zotero. kasamalidwe ka netiweki, ndi kuyang'anira.
