Chotumiza cha Kunja cha 1550nm
Chotumizira chamkati ichi chimatembenuza ma RF-to-optical signal mu ulalo wa 1550nm.
Chikwama cha 1U 19' chokhazikika chokhala ndi chiwonetsero cha kristalo chamadzimadzi (LCD/VFD) kutsogolo;
Bandwidth ya pafupipafupi: 47—750 / 862MHz;
Mphamvu yotulutsa kuyambira 4 mpaka 24mw;
Dongosolo lokonzekera bwino lisanayambe kupotoza;
AGC/MGC;
Kulamulira mphamvu zokha (APC) ndi dera lolamulira kutentha zokha (ATC).
Mbali Chowongolera chakunja ndi laser zonse zimatumizidwa kuchokera ku United States kapena Japan.
Dongosolo loyenera la pre-distortion limatsimikizira CTB ndi CSO zabwino kwambiri pamene CNR ili pamlingo wapamwamba.
Chigawo chabwino kwambiri cha SBS choletsa komanso chosinthika cha SBS mu 13, 16, 18, choyenera mitundu yosiyanasiyana ya netiweki ya CATV.
Kulamulira kwa AGC.
Mphamvu ziwiri zamkati zomwe zingasinthidwe zokha.
Kuwongolera kutentha kokha.
Mapulogalamu amkati a microprocessor ali ndi ntchito yowunikira laser, kuwonetsa magawo, chenjezo la zolakwika, kuyang'anira ukonde ndi zina zotero. Gawo logwira ntchito la laser likangotha pamtengo wokhazikika wa pulogalamuyo, makinawo amachenjeza.
Chotumiziracho chimapereka mawonekedwe a RJ45 ndi RS232 olumikizira kompyuta ndi kuwunika.
