I-1550nm i-Optical Transmitter yangaphandle
Olu chungechunge lwangaphakathi-modulated transmitter lwenza iRF-to-optical uguqulo lwesiginali kwi-1550nm yothumelo lwekhonkco.
Icala le-1U 19 'eliqhelekileyo kunye nomboniso wekristale yolwelo (LCD / VFD) kwiphaneli yangaphambili;
I-bandwidth yefrikhwensi: 47-750 / 862MHz;
Imveliso yamandla ukusuka kwi-4 ukuya kwi-24mw;
Isiphaluka esiphuculweyo sokulungiswa kwangaphambili;
AGC/MGC;
Ulawulo lwamandla oluzenzekelayo (APC) kunye nolawulo oluzenzekelayo lobushushu (ATC).
Uphawu Zombini imodyuli yangaphandle kunye nelaser zingeniswa zisuka eUnited States okanye eJapan.
Isekethe egqibeleleyo yangaphambi kokuphazamiseka iqinisekisa eyona CTB kunye neCSO xa i-CNR ikwizinga eliphezulu.
I-SBS egqibeleleyo yokucinezela isekethe kunye ne-SBS ehlengahlengiswayo kwi-13, 16, 18, ilungele iintlobo ezahlukeneyo zenetha yeCATV.
Ulawulo lwe-AGC.
Amandla amabini angaphakathi angatshintshwa ngokuzenzekelayo.
Iqokobhe ngokuzenzekelayo ulawulo lobushushu.
Isoftware yemicroprocessor yangaphakathi inomsebenzi wokujongwa kwelaser, umboniso weparamitha, isilumkiso sempazamo, ulawulo lomnatha njalo njalo.Emva kokuba iparameter yokusebenza ye-laser iphuma kwixabiso elimiselweyo lesofthiwe, umatshini uya kulumkisa.
I-transmitter ibonelela nge-RJ45 kunye ne-RS232 ujongano oluqhelekileyo lokudibanisa ikhompyuter kunye nokubeka iliso.
