NKWA NKEKWU:
SR100SC3 usoro CATV Ntụgharị maka dijitalụ telivishọn, eriri ka n'ụlọ. Igwe a na-anabata tube na-anata ngwa anya dị elu, na-enweghị ọkụ ọkụ, na enweghị ike oriri. Mgbe ntinye anya ike mmepụta larịị Pin = -1dBm, Vo = 6 8dB V, nwere ike itinye n'ụzọ akụ na ụba na ngbanwe maka ntinye nke netwọk atọ, eriri na ngwa netwọk ụlọ. SR100 ọdịdị nke enamel, e nwere ụdị abụọ nke ngwa anya mode nhọrọ:
1.SR100SC3: CATV arụ ọrụ wavelength 1260 ~ 1620nm.
2.SR100SC3-1550: Wuru n'ime 1310 / 1490nm filter, adabara otu-fiber triple wavelength system, CATV Operating wavelength 1550nm.
Atụmatụ:
-Nhọrọ maka Wavelength Pass/Stop Filter
-Nhọrọ maka F-ụdị nwoke na nwanyị njikọ
-Ebere maka netwọkụ FTTH (Fiber To The Home).
-Ezigbo linearity na flatness
-Gba elu nke ike ntinye anya
- Single-mode eriri elu nloghachi ọnwụ
- Iji GaAs amplifier arụ ọrụ ngwaọrụ
-Ultra ala mkpọtụ teknụzụ
-obere nha na mfe ịwụnye
IHE:
1. SR100SC3 na igbe set-top (STB) nke ọdụ ụgbọ mmiri RF jikọtara ya.
2. Mgbe ị na-eji njikọ RF, ihe ntinye ntinye RF ga-agbatịrịrị na STB. Ma ọ bụghị ya, ala dị njọ ma nwee ike ịkpata akụkụ dị elu nke ihe ngosi TV Dijitalụ MER mmebi.
3. Debe njikọ anya dị ọcha, njikọ ọjọọ ahụ ga-eme ka ọkwa mmepụta RF dị ala
