Isidluliseli Sokubona Sangaphandle esingu-1550nm
Lolu chungechunge lwe-transmitter oluguquliwe lwangaphakathi lwenza ukuguqulwa kwesignali ye-RF-to-optical kusixhumanisi sokudlulisa esingu-1550nm.
Ikesi elijwayelekile elingu-1U elingu-19' elinesibonisi sekristalu eliwuketshezi (i-LCD/VFD) ephaneli engaphambili;
Ububanzi bemvamisa: 47—750 / 862MHz;
Amandla okukhipha kusukela ku-4 kuya ku-24mw;
Isekethe yokulungisa ngaphambi kokuhlanekezela ethuthukisiwe;
I-AGC/MGC;
Ukulawula amandla okuzenzakalelayo (i-APC) kanye nesekethe yokulawula izinga lokushisa okuzenzakalelayo (i-ATC).
Isici Kokubili i-modulator yangaphandle kanye ne-laser kungeniswa kusuka e-United States noma eJapane.
Isekethe efanelekile yangaphambi kokuhlanekezelwa iqinisekisa i-CTB ne-CSO engcono kakhulu uma i-CNR isezingeni eliphezulu.
Isekethe yokucindezela i-SBS ephelele kanye ne-SBS elungisekayo ku-13, 16, 18, efanele izinhlobo ezahlukene ze-net ye-CATV.
Ukulawulwa kwe-AGC.
Amandla angaphakathi aphindwe kabili angashintshwa ngokuzenzakalelayo.
Ukulawula izinga lokushisa ngokuzenzakalelayo.
Isofthiwe yangaphakathi ye-microprocessor inomsebenzi wokuqapha nge-laser, ukubonisa amapharamitha, isexwayiso samaphutha, ukuphathwa kwenethi njalo njalo. Uma ipharamitha yokusebenza ye-laser isiphelile enanini elimisiwe lesofthiwe, umshini uzoxwayisa.
I-transmitter inikeza isikhombikubona esijwayelekile se-RJ45 kanye ne-RS232 sokuxhuma ikhompyutha nokuqapha.
Ipharamitha Yezobuchwepheshe
Izinto Iyunithi Amapharamitha Ezobuchwepheshe Amandla Okukhanya Okukhiphayo i-dBm 3 4 5 6 7 8 9 10 Ubude be-Optical Wave nm 1550±10 noma ubude be-ITU Uhlobo lwe-Laser I-DFB Laser Imodi Yokulawula Optical Ukuguqulwa Kwe-Intension Okuqondile Uhlobo Lwesixhumi Esibonakalayo I-FC/APC noma i-SC/APC Ibanga Lokuvama I-MHz 47~862 Izinga Lokufaka i-dBμV 72~88 Ukuthamba ebhendini dB ±0.75 Ukuvimba Kokufaka Ω 75 Ukulahlekelwa Kokubuyisela Kokufaka dB ≥ 16(47~550)MHz;≥ 14(550~750/862MHz) I-C/CTB dB ≥ 65 I-C/CSO dB ≥ 60 C/N dB ≥ 51 Ububanzi Obulawulwa yi-AGC dB ±8 Ububanzi Obulawulwa yi-MGC dB 0~10 I-Voltage Yokunikezela V I-AC 160V~250V(50 Hz) Ukusetshenziswa Kwamandla W 30 Izinga Lokushisa Lokusebenza ℃ 0 ~+45 Izinga Lokushisa Lesitoreji ℃ -20 ~+65 Umswakama Olinganiselwe % Ubuningi obungu-95% Akukho ukujiya Ubukhulu mm 483(L)X 380(W)X 44(H)
