FTTH onye nnata ngwa anya (CT-2002C)
Nchịkọta
Ngwaahịa a bụ onye na-anata ngwa anya FTTH, na-eji obere ike na-anata ngwa anya na njikwa ngwa anya AGC technology, nke nwere ike gboo mkpa nke fiber-to-the-home, na enwere ike iji ya na ONU ma ọ bụ EOC iji nweta egwuregwu atọ.E nwere WDM, 1550nm CATV mgbaàmà photoelectric ntughari na RF mmepụta, 1490/1310 nm PON mgbaàmà na-agafe ozugbo, nke nwere ike izute FTTH otu ngwa anya fiber nnyefe CATV + XPON. na rube isi na XGSPON gburugburu ebe obibi,
Ngwaahịa a bụ kọmpat na nhazi yana dị mfe ịwụnye, ọ bụkwa ngwaahịa dị mma maka iwulite netwọkụ TV FTTH USB.

FAQ
FTTH Onye nnata ngwa anya ajụjụ a na-ajụkarị
Q1.Kedu ihe bụ nnata ngwa anya FTTH?
A: Ihe nnata anya FTTH bụ ngwaọrụ eji na netwọk fiber-to-the-home (FTTH).Emebere ya ka ọ nweta akara ngosi anya site na netwọk fiber optic wee gbanwee ha ka ọ bụrụ akara eletrik maka nhazi ọzọ.
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).Teknụzụ AGC na-eme ka ike anya ngwa anya enwetara na-anọgide n'ime oke dị iche iche site n'ịgbanwe uru nke nnata.Nke a na-eme ka nnabata mgbaàmà ntụkwasị obi yana ịrụ ọrụ kacha mma.
Q3.Kedu uru dị na iji FTTH optical receiver?
A: Iji ndị na-anata ngwa anya FTTH na-eweta ọtụtụ uru na netwọkụ FTTH.Ọ na-eme ka nnabata na ntụgharị mgbama fiber optic rụọ ọrụ nke ọma, na-eme ka ịntanetị dị elu, TV dijitalụ dị elu yana ọrụ olu doro anya.Na mgbakwunye, enwere ike ijikọ ya na otu Optical Network Unit (ONU) ma ọ bụ Ethernet over Coax (EOC) maka ọrụ egwuregwu ugboro atọ.
Q4.Kedu ihe bụ ngwa nke ndị nnata anya anya FTTH?
A: A na-ejikarị ndị na-anata ngwa anya FTTH na netwọk FTTH iji jikọọ ụlọ obibi ma ọ bụ azụmahịa na akụrụngwa fiber optic.Ọ na-arụ ọrụ dị ka ngwaọrụ njedebe nke na-ewere akara ngosi anya na-aga site na eriri fiber optic wee tụgharịa ha na akara eletrik dabara adaba maka ọrụ dị iche iche, gụnyere ịntanetị, telivishọn, na olu.
Q5.Enwere ike iji ihe nnata anya FTTH na ngwa ndị ọzọ?
A: Ee, enwere ike iji ihe nnabata anya FTTH yana ONU ma ọ bụ EOC iji nweta ọrụ egwuregwu atọ.ONU na-arụ ọrụ dị ka ebe etiti maka ikesa ịntanetị, TV na akara olu n'ime ụlọ ahụ, ebe ndị na-anata ngwa anya FTTH na-ahụ maka nnabata a pụrụ ịdabere na ya na ngbanwe nke akara ndị a.Ha na-akwado njikọta enweghị nkebi na ọrụ mgbasa ozi na netwọk FTTH.
