Kedu ihe bụ FTTH/FTTO?
N'ụwa nke dijitalụ-centric nke taa, njikọ ịntanetị na-agba ọsọ abụghịzi ihe okomoko kama ọ dị mkpa.Ka ọchịchọ maka ịntanetị ngwa ngwa na ntụkwasị obi na-aga n'ihu na-eto eto, ụlọ ọrụ mgbasa ozi na-aga n'ihu na-enyocha teknụzụ ọhụrụ iji gboo mkpa ndị ahịa.Gigabit Passive Optical Network (GPON) bụ teknụzụ na-agbanwegharị ụlọ ọrụ brọdband.N'isiokwu a, anyị ga-enyocha uru nke GPON, kpọmkwem iji 16-port, three-layer OLT and FTTH optical terminal iji meziwanye arụmọrụ na arụmọrụ netwọk.
GPON bụ ihe owuwu netwọk fiber-optic nke na-ebuga ịntanetị, olu, na ọrụ vidiyo dị elu nye ndị ọrụ obibi na azụmaahịa.Ọ na-eji a point-to-multipoint topology, tinye n'ọrụ na-agafe agafe optical splitters kesaa data n'ọtụtụ ahịa n'out oge.GPON na-eji usoro mbufe Layer 2 na-ebufe data, na-enye nnukwu bandwidth ruru 2.5 Gbps downstream yana 1.25 Gbps elu.
Isi nke netwọk GPON bụ ọdụ eriri anya (OLT).Ikike OLT's Layer 3 na-eme ka oke nke akụrụngwa netwọkụ rụọ ọrụ nke ọma na ụzọ ọgụgụ isi nke ngwugwu.Site na OLT nke na-akwado ike Layer 3, ndị na-enye telecom nwere ike hụ na okporo ụzọ kachasị mma, belata mkpọkọ, ma kwalite ịrụ ọrụ netwọk.Na mgbakwunye, Layer 3 OLT na-enye atụmatụ nchekwa dị elu dị ka nzacha IP na nchekwa firewall iji chebe netwọkụ site na ihe iyi egwu.
Ụdị fiber-to-the-home (FTTH) na-enyere aka site na teknụzụ GPON ma na-eji eriri fiber optic na-enye njikọ eriri kpọmkwem na ụlọ ma ọ bụ azụmahịa ọ bụla.N'ịbụ ndị nwere ọtụtụ ọdụ ụgbọ mmiri 16, obere ngwaọrụ ndị a nwere ike ijikwa nkesa na njedebe nke akara ngosi anya, na-eme ka njikọ na-enweghị ntụpọ na netwọk niile.Ọnụ ọnụ anya FTTH na-arụ ọrụ dị ka àkwà mmiri n'etiti eriri anya na Ethernet, na-eme ka nnyefe data dị elu na ọrụ mgbasa ozi a pụrụ ịdabere na ya.
GPON nwere ọtụtụ uru mgbe ejikọtara ya na atọ oyi akwa OLT na FTTH ngwa anya.Nke mbụ, ọ na-enye ikike bandwidth na-enweghị atụ iji gboo mkpa data na-eto eto nke ndị ahịa.Nkà na ụzụ na-ebelatakwa ike oriri, na-eme ka ọ bụrụ ngwọta enyi na gburugburu ebe obibi.Ọzọkwa, GPON's scalability na-enyere mgbasawanye netwọkụ ọnụ ahịa aka na akụrụngwa akaebe ga-eme n'ọdịnihu.
Na nkenke, nchikota nke ọdụ ụgbọ mmiri 16, OLT atọ na FTTH optical terminal agbanweela ụlọ ọrụ brọdband kpamkpam.Teknụzụ GPON na-eweta njikọta ọsọ-ọsọ, njikwa akụrụngwa na-arụ ọrụ nke ọma yana nchekwa nchekwa na netwọkụ ekwentị.Site n'inweta GPON, ndị na-enye ọrụ nwere ike inye ndị ahịa ha ọrụ ịntanetị enweghị nkebi, olu na vidiyo na-ezute ma gafere atụmanya ha na oge dijitalụ a.
