1550nm Whakawhiti Optical Waho
Ko tenei raupapa-a-roto-whakawhitinga whakawhiti e mahi ana i nga huringa tohu RF-ki-optical i roto i te hononga tuku 1550nm.
1U 19 'take paerewa me te whakaaturanga karaihe wai (LCD / VFD) i te panui o mua;
Auaumoka: 47—750 / 862MHz;
Te mana whakaputa mai i te 4 ki te 24mw;
Te ara iahiko whakatika i mua i te paheketanga;
AGC/MGC;
Mana mana aunoa (APC) me te ara iahiko te pāmahana Aunoa (ATC).
Āhuahira Ko te modulator o waho me te laser ka kawemai mai i te United States, i Japan ranei.
Ko te ara iahiko i mua i te korikori tino pai ka whakarite i te CTB me te CSO pai rawa atu ina he taumata teitei te CNR.
SBS tino pehi iahiko me te SBS taea te whakarite i roto i te 13,16, 18, e tika ana mo nga momo momo kupenga CATV.
Mana AGC.
Te mana rua o roto ka taea te huri aunoa.
Mana anga te pāmahana aunoa.
Ko te rorohiko microprocessor o roto te mahi o te aroturuki taiaho, te whakaatu tawhā, te whakatupato hapa, te whakahaere kupenga me era atu.Kia puta te tawhā mahi o te taiaho i te uara kua whakaritea o te rorohiko, ka whakatupato te miihini.
Ka whakaratohia e te kaituku te RJ45 me te RS232 atanga paerewa mo te hono i te rorohiko me te aroturuki.
