FTTH onye nnata ngwa anya (CT-2001C)
Nchịkọta
Ngwaahịa a bụ ihe nnata ngwa anya FTTH. Ọ na-anabata nnabata ngwa anya dị ala yana njikwa ngwa anya teknụzụ AGC iji gboo mkpa nke eriri-na-ụlọ. Jiri ntinye ngwa anya egwuregwu atọ, jikwaa nkwụsi ike mgbaama site na AGC, yana WDM, 1100-1620nm CATV ngbanwe fotoelectric na mmemme RF mmepụta USB.
Ngwaahịa ahụ nwere njirimara nke nhazi kọmpat, ntinye dị mma na ọnụ ala dị ala. Ọ bụ ezigbo ngwaahịa maka iwulite netwọkụ TV FTTH.
Njirimara
> Shei rọba dị elu nwere oke ọkụ dị elu.
> Ọwa RF zuru GaAs sekit amplifier mkpọtụ dị ala. Opekempe nnabata nke akara dijitalụ bụ -18dBm, yana nnabata kacha nta nke akara analọgụ bụ -15dBm.
> Oke njikwa AGC bụ -2 ~ -14dBm, na mmepụta adịghị agbanwe agbanwe. (enwere ike ịhazi oke AGC dị ka onye ọrụ si dị).
> Nhazi ike dị ala, na-eji ọkụ ọkụ na-agbanwe ike dị elu iji hụ na ntụkwasị obi dị elu na nkwụsi ike nke ike ọkụ. Oriri ike nke igwe dum erughị 3W, yana sekit nchọpụta ìhè.
> WDM wuru n'ime, ghọta otu ntinye eriri (1100-1620nm).
> SC/APC na SC/UPC ma ọ bụ FC/APC ngwa anya njikọ, metric ma ọ bụ inch RF interface nhọrọ.
> Ụdị ọkọnọ ike nke ọdụ ụgbọ mmiri 12V DC.

FAQ
Q1. Kedu ihe bụ nnata ngwa anya FTTH?
A: FTTH optical receiver bụ ngwaọrụ eji na netwọk fiber-to-the-home (FTTH) iji nweta akara ngosi anya na-ebufe site na eriri anya wee gbanwee ha ka ọ bụrụ data ma ọ bụ akara eji eme ihe.
Q2. Kedu ka ihe nnata anya FTTH si arụ ọrụ?
A: Onye na-anata anya ngwa anya FTTH na-anabata nnabata ngwa anya dị ala yana teknụzụ njikwa akpaka anya (AGC). Ọ na-anabata ntinye anya egwuregwu ugboro atọ ma na-edobe nkwụsi ike mgbaama site na AGC. Ọ na-atụgharị akara CATV 1100-1620nm na mmepụta RF eletriki maka mmemme USB.
Q3. Kedu uru dị na iji FTTH optical receiver?
A: Uru nke iji FTTH ndị na-anata ihe anya na-agụnye ikike ịkwado ntinye fiber-na-na-ụlọ, nke nwere ike ịnye ọrụ ịntanetị ngwa ngwa, TV na ekwentị na otu eriri. Ọ na-enye ike dị ala, nnabata mgbaama kwụsiri ike yana ngbanwe fotoelectric dị elu maka akara CATV.
Q4. Ihe nnata ngwa anya FTTH nwere ike ijikwa ogologo ogologo ogologo ogologo dị iche iche?
A: Ee, FTTH ndị na-anata ngwa anya na WDM (Wavelength Division Multiplexing) ikike nwere ike ijikwa ogologo oge dị iche iche, na-emekarị n'etiti 1100-1620nm, na-enyere ha aka ijikwa akara CATV dị iche iche na-ebufe n'elu eriri fiber optic.
Q5. Kedu ihe ọ pụtara na teknụzụ AGC na nnata ngwa anya FTTH?
A: Teknụzụ njikwa njikwa akpaaka (AGC) na ndị na-anata anya FTTH na-eme ka nkwụsi ike mgbaàmà site n'ịgbanwe ike ntinye anya iji nọgide na-enwe ọkwa mgbaàmà na-agbanwe agbanwe. Nke a na-enyere ndị a pụrụ ịdabere na ya, mgbasa ozi CATV na-akwụsịghị akwụsị, na-eme ka arụmọrụ kacha mma maka ngwa fiber-to-the-home.
