Umthumeli we-Optical wangaphandle we-1550nm
Olu thotho lwe-transmitter oluqhutywa ngaphakathi lwenza ukuguqulwa kwesignali ye-RF ukuya kwi-optical kwikhonkco lokudlulisela le-1550nm.
Ibhokisi eqhelekileyo eyi-1U 19' enesikrini sekristale yolwelo (LCD/VFD) kwiphaneli engaphambili;
Ibhendi yokuphindaphinda: 47—750 / 862MHz;
Amandla okukhupha ukusuka kwi-4 ukuya kwi-24mw;
Isekethe yokulungisa kwangaphambili ukuphambuka ephucukileyo;
I-AGC/MGC;
Ulawulo lwamandla oluzenzekelayo (APC) kunye nesekethe yolawulo lobushushu oluzenzekelayo (ATC).
Uphawu Zombini i-modulator yangaphandle kunye ne-laser zingeniswa zivela eMelika okanye eJapan.
Isekethe egqibeleleyo yangaphambi kokuphazamiseka iqinisekisa i-CTB kunye ne-CSO ezilungileyo xa i-CNR ikumgangatho ophezulu.
Isekethe yokucinezela ye-SBS egqibeleleyo kunye ne-SBS ehlengahlengiswayo kwi-13, 16, 18, efanelekileyo kwiintlobo ezahlukeneyo ze-net ye-CATV.
Ulawulo lwe-AGC.
Amandla angaphakathi aphindwe kabini anokutshintshwa ngokuzenzekelayo.
Ulawulo lobushushu oluzenzekelayo.
Isoftware yangaphakathi ye-microprocessor inomsebenzi wokubeka esweni i-laser, ukubonisa iiparameter, isilumkiso sempazamo, ulawulo lwe-net njalo njalo. Nje ukuba iparameter yokusebenza ye-laser iphume kwixabiso elimiselweyo lesoftware, umatshini uya kulumkisa.
Isixhobo sokudlulisa idatha sinika ujongano oluqhelekileyo lwe-RJ45 kunye ne-RS232 lokudibanisa ikhompyutha kunye nokubeka esweni.
