Transmitter iyi ndi cholozera chapamwamba, chogwira ntchito zambiri 1550nm mkati modulitsidwa optical transmitter pamlingo wapamwamba.Imatengera laser yamtundu wa DFB yayikulu, yokhala ndi chipukuta misozi chokhazikika komanso kuwongolera kwa AGC, APC, ndi ATC, zomwe zimathandizira kwambiri kalozera wadongosolo.
ST1550I mndandanda 1550nm mkati modulated Optical transmitter ndiye chida chachikulu pomanga ma netiweki akusekondale a CATV.Imagwiritsidwa ntchito kwambiri pazowonjezera zamtengo wapatali monga ma sigino a zithunzi za pa TV, ma siginecha a TV a digito, ma siginecha amafoni, ndi ma data (kapena ma data oponderezedwa).Ndi njira yabwino kwambiri koma yotsika mtengo kuti muzindikire sewero la katatu ndi makina otumizira maukonde a FTTx.
Mawonekedwe Ogwira Ntchito
1. Imatengera chirp choyambirira chotsika ndi mzere wapamwamba wa DFB laser ngati gwero lazizindikiro.
2. Dongosolo lokonzekera bwino lomwe lisanayambe kusokoneza limatsimikizira kuti CTB ndi CSO zimagwira ntchito bwino pamtengo wapamwamba wa CNR.
3. Kuwongolera kwa Automatic gain (AGC) kumathandizira kutulutsa kokhazikika m'magawo osiyanasiyana olowetsa a RF.
4. Ma network osiyanasiyana amatha kukonzedwa ndi kusintha kwa OMI.
5. Kuwongolera kutentha kwamilandu kwathunthu, mafani anzeru, mafani amayamba kugwira ntchito pomwe kutentha kwamilandu kumafika 30 ℃.
6. Magetsi omangidwa pawiri osunga zobwezeretsera, pulagi yotentha, ndi switch yodziwikiratu imathandizidwa.
7. Magawo ogwirira ntchito a makina onse amayendetsedwa ndi microprocessor ndipo mawonekedwe a LCD kutsogolo ali ndi ntchito zambiri monga laser status monitoring, parameter display, fault alarm, network management, etc.;kamodzi magawo ogwirira ntchito a laser achoka pamtundu wololedwa wokhazikitsidwa ndi pulogalamuyo, dongosololi lidzakhala alamu mwachangu.
8. Mawonekedwe ovomerezeka a RJ45 operekedwa, akuthandizira kayendetsedwe ka maukonde akutali a SNMP ndi WEB.
