I-1550nm I-Optical Transmitter yangaphandle
Lolu chungechunge lwe-transmitter eshintshiwe yangaphakathi lwenza ukuguqulwa kwesiginali ye-RF-to-optical kusixhumanisi sokudlulisa esingu-1550nm.
Ikesi elijwayelekile elingu-1U 19' eline-liquid crystal display (LCD/VFD) kuphaneli yangaphambili;
Umkhawulokudonsa wemvamisa: 47—750 / 862MHz;
Amandla okukhipha kusuka ku-4 kuya ku-24mw;
Isifunda sokulungisa sangaphambi kokuhlanekezela okuthuthukisiwe;
I-AGC/MGC;
Ukulawulwa kwamandla okuzenzakalelayo (APC) kanye nesekhethi yokulawula izinga lokushisa okuzenzakalelayo (ATC).
Isici Kokubili i-modulator yangaphandle kanye ne-laser kungenisa kusuka e-United States noma e-Japan.
Umjikelezo ophelele wangaphambi kokuhlanekezela uqinisekisa i-CTB ne-CSO ehamba phambili uma i-CNR isezingeni eliphezulu.
Isekhethi ephelele yokucindezela i-SBS kanye ne-SBS elungisekayo ku-13, 16, 18, ilungele izinhlobo ezahlukene zenethi yeCATV.
Ukulawulwa kwe-AGC.
Amandla angaphakathi aphindwe kabili angashintshwa ngokuzenzakalelayo.
Ukulawula izinga lokushisa kwegobolondo ngokuzenzakalela.
Isofthiwe ye-microprocessor yangaphakathi inomsebenzi wokuqapha kwe-laser, ukubonisa ipharamitha, isixwayiso samaphutha, ukuphathwa kwenetha nokunye.Uma ipharamitha yokusebenza ye-laser iphuma enanini elimisiwe lesofthiwe, umshini uzoxwayisa.
I-transmitter inikeza i-RJ45 ne-RS232 isikhombimsebenzisi esijwayelekile sokuxhuma ikhompuyutha nokuqapha.
