I-1310nm i-Optical Transmitter
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).
