Modul anya bụ ngwaọrụ optoelectronic nke na-eme mgbanwe fotoelectric na electro-optical.Ọgwụgwụ nnyefe nke modul ngwa anya na-atụgharị mgbama eletrik ka ọ bụrụ akara ngosi anya, na njedebe nnata na-atụgharị akara ngosi anya na mgbama ọkụ.Feiyu Fiber na-egosi ngwa nke modul anya na ụlọ ọrụ dị iche iche.Akụkụ ngwa ngwa nke modul ngwa anya gụnyere: 1. Ebe data;2. Ebe nkwurịta okwu ekwentị mkpanaaka;3. Pasive wavelength nkewa usoro;4. netwọk nchekwa SAN / NAS;5. 5G onye na-ebu netwọk.
1. Ebe data.
Ebe data dị ugbu a abụghịzi naanị otu ọnụ ụlọ kọmputa ma ọ bụ ọtụtụ, kama ọ bụ otu ụyọkọ data center.Iji ghọta ọrụ nkịtị nke ọrụ ịntanetị dị iche iche na ahịa ngwa, achọrọ ebe data iji rụọ ọrụ na nhazi.Ngbanwe ozi n'ezie n'etiti ebe data ewepụtala ọchịchọ maka netwọk njikọ njikọ data center, na nkwurịta okwu fiber optical aghọwo ụzọ dị mkpa iji nweta njikọ.
Dị iche na omenala telecom ohere netwọk nnyefe akụrụngwa, data center interconnection chọrọ elu ọsọ, obere ike oriri, na ndị ọzọ miniaturization nke ịmafe akụrụngwa iji nweta ibu na ọzọ kpụ ọkụ n'ọnụ nnyefe nke ozi.Isi ihe na-ekpebi ma arụmọrụ ndị a nwere ike mezuo bụ modul anya.
Enwere ike ikewa modul anya nzikọrịta data center ụzọ atọ dịka ụdị njikọ siri dị:
(1) Site na ebe data na onye ọrụ, a na-emepụta ya site na omume njedebe njedebe dị ka ịnweta igwe ojii iji chọgharịa na weebụ, zipu ma nata ozi ịntanetị, na iyi vidiyo;
(2) Njikọ njikọ data center, nke a na-ejikarị emegharị data, ngwanrọ na nkwalite usoro;
(3) N'ime ebe data, a na-ejikarị ya maka nchekwa ozi, ọgbọ na ngwuputa.Dị ka amụma Cisco si kwuo, nkwurịta okwu dị n'ime nke ebe data na-akpata ihe karịrị 70% nke nkwurịta okwu nke data center.Nnukwu mmepe nke owuwu ebe data amụwokwa mmepe nke modul ngwa anya dị elu.
2. Ụlọ ọrụ nzikọrịta ozi ekwentị.
Ebe ọdụ nzikọrịta ozi mkpanaka na-ezo aka na ọdụ redio transceiver nke na-ebufe ozi n'etiti ebe ngbanwe nzikọrịta ekwentị na ọnụ ekwentị ekwentị n'otu mpaghara mkpuchi redio.
Ebe ọdụ nzikọrịta ozi ekwentị nke onye na-arụ ọrụ chọkwara modul anya iji ghọta njikọ dị n'etiti ngwaọrụ.Ebe ọdụ ụgbọ ala nwere ngwaọrụ RRU na BBU.N'ime ngwa ahụ, anyị kwesịrị ijikọ njikọ dị n'etiti ngwaọrụ abụọ a, nke chọrọ modul anya anyị.Na netwọk 4G, akụrụngwa eji ejikọta BBU na RRU bụ tumadi 1.25G optical modul, 2.5G modul optical, 6G optical modul, 10G optical modul, wdg.
3. Usoro WDM na-agafe agafe
N'ime usoro teknụzụ anabatara na 5G fronthaul, WDM na-agafe agafe enweghị ịrụ ụka na ọ bụ ọnụ ọgụgụ kachasị elu.Sistemụ WDM na-agafe agafe nwere modul ngwa anya agba, multiplexer na eriri anya.
Ụkpụrụ bụ isi nke nkà na ụzụ nkewa ogologo wavelength na-agafe agafe bụ iji teknụzụ WDM ijikọ akara ngosi anya dị iche iche ma na-ebu usoro ozi n'ime otu ngwugwu, ma bufee ha n'otu eriri anya iji ghọta mgbasa ozi n'etiti ọrụ.WDM nwere ike n'otu oge na-ebufe ọtụtụ mgbaama n'otu eriri anya.Ọ nwere ike ibunye mgbaama ọ bụla na ogologo ogologo ọkụ nke dabara na mgbama ahụ, enwere ike kewapụ akara ngosi anya nke ogologo ebili mmiri dị iche iche na njedebe nnata.Sistemụ nkewa wavelength na-agafe agafe bụ usoro nke akụkụ abụọ mejupụtara: modul ìhè agba na OTM.
4. SAN / NAS nchekwa netwọk.
Site na mmepe ngwa ngwa nke ịntanetị na ngwa netwọkụ, ụdị data a ga-ahazi site na sistemụ nchekwa data na-abawanye nke ukwuu, nke na-eme ka usoro nchekwa data na-eche ihe ịma aka na-enwetụbeghị ụdị ya ihu.Ngwa nchekwa netwọkụ ndị ọzọ (Network Attached Storage, abbreviated as NAS) na mpaghara nchekwa netwọk (Storage Area Network, abbreviated as SAN), ha nwere ike ikewapụ ngwaọrụ nchekwa data na netwọk na usoro nnabata, ma centralized management nke ozi data. na Na ezi scalability, ọ na-enye ihe ngwọta kasị dị irè maka ịghọta centralized data management.
Isi ọrụ nke netwọk nchekwa SAN/NAS bụ ịchekwa data.N'ime ha, netwọk SAN bụ nke kachasị nke sava, eriri ọwa eriri, ngwaọrụ nchekwa, na ndị na-ebufe nnyefe (modul optical, fiber jumpers);NAS nchekwa netwọk bụ tumadi mejupụtara NAS nchekwa, switches, Nke mejupụtara ngwa ngwa (kọmputa), nnyefe ụgbọelu (optical modul, optical fiber jumper).
Ekwesiri iburu n'uche na netwọk SAN na-eji modul optical Fiber Channel ma ọ dị mkpa ịkwado FC Fiber Channel protocol, ebe modul ngwa anya ejiri na netwọk nchekwa NAS kwesịrị ịkwado usoro Ethernet.
5. 5G onye na-ebu netwọk.
A na-ekewa netwọk 5G n'ime akụkụ atọ, ya bụ netwọk ịnweta, netwọk bearer na netwọk isi.Iji ghọta mmekọrịta dị n'etiti ha, ị nwere ike ịtu aka na foto a:
A na-ekewa netwọkụ onye na-ebu 5G ka ọ bụrụ oyi akwa ohere mepere emepe, akwa nchịkọta obodo, yana ahịrị isi akwa akwa / mpaghara mpaghara iji ghọta ọrụ fronthaul na midhaul nke ọrụ 5G.
Ihe ngosi ngwa ngwa nke 5G fronthaul gụnyere njikọ eriri kpọmkwem, WDM na-agafe agafe na WDM nọ n'ọrụ, wdg.
Ihe achọrọ maka modul anya na ọnọdụ ngwa ngwa fronthaul 5G bụ ndị a:
① Zute okpomọkụ nke ụlọ ọrụ mmepụta ihe, ihe ndị a pụrụ ịdabere na ya: N'ịtụle ebe a na-arụ ọrụ n'èzí, modul ngwa anya nke fronthaul ga-ezute ụlọ ọrụ mmepụta ihe nke -40 ℃ ~ + 85 ℃, ma ọ dịkwa mkpa iji mezuo ihe mkpuchi uzuzu chọrọ.
② Ọnụ ego dị ala: Achọ maka modul ngwa anya 5G karịrị nke 4G, ọkachasị maka modul optical fronthaul.Ọnụ ala dị ala bụ otu n'ime ihe ndị achọrọ maka modul anya na ụlọ ọrụ 5G.5G ọkara na azụ azụ na-ekpuchi oghere ohere, akwa nchịkọta na isi oyi akwa nke mpaghara mepere emepe.Modul ngwa anya achọrọ adịghị iche na teknụzụ modul optical ejiri na etiti data dị ugbu a.Oghere ohere ahụ ga-eji 25Gb/s, 50Gb/s, 100Gb/s Maka ngwa anya modul nke s na ọnụego ndị ọzọ, a ga-ejikarị modul anya DWDM nwere ọnụego 100Gb/s, 200Gb/s, na 400Gb/s. mkpokọta oyi akwa na n'elu.
N'ikpeazụ, ekwesịrị ikwu na uto nke modul anya na-adabere na ahịa nkwukọrịta data na ahịa telecom.N'ọgbọ data nke taa, modul anya ga-ewebata ohere mmepe ọhụrụ.
Huanet nwere ike ịnye ụdị modul ngwa anya niile, nabata ịkpọtụrụ maka ọnụ ahịa.
