5G arumoni, te kawe tuatahi. Nā te tere o te whakatinanatanga o ngā whatunga 5G, hei tētahi o ngā kawe taketake o te umanga 5G katoa, kei te kaha haere te hiahia mō ngā whatunga fronthaul 5G. I te wā 5G, ko te whatunga urunga reo irirangi e hangai ana ki te hoahoa C-RAN, ka whakatinanahia te DU i roto i te huarahi pokapū, ā, he maha ngā AAU e honoa ana mā te whatunga fronthaul. Ko ngā otinga fronthaul e whakaarohia ana e C-RAN ko te nuinga o te muka whatu taraiwa tika, te WDM kore mahi me ngā otinga OTN hohe, he raruraru pēnei i te nui o te whakamahinga rauemi muka, te kore whakahaere me te utu nui; Kei te whakapau kaha a Shenzhen HUANET Technology Co., Ltd. ki te hanga i tētahi whatunga fronthaul 5G kounga teitei, ko ia te tuatahi ki te whakarewa i tētahi otinga haurua-hohe 5G fronthaul, e whakapai ake ana i te pono o te whatunga me te whakapai ake hoki i te whakahaere me te whakahaere me te tiaki i te whatunga fronthaul.

Ngā āhuatanga o te hōtaka
Tautokohia te CPRI 1 ~ 10 me te eCPRI (10G / 25G), e hototahi ana ki te STM-1 / 4 / 16 / 64, GE / 10GE / 25GE me etahi atu kaiwhakarato kotahi maha-ratonga, te tuku mārama, te whakanui ake i te uara o te whatunga fronthaul.
Whirihoranga modular, 1:6/12/18 kōwhiringa, ka taea te whakatutuki i te huihuinga maha-taumata maha-aronga, te penapena muka tauine nui
Ka taea te whakarato i ngā momo kōwae rama tae, e tautoko ana i ngā ngaru CWDM 18, ngā ngaru MWDM 12, me te whakatutuki i ngā whakaritenga taupū tahua mana raina.
Tautoko i te parenga paparanga whatu 1:1, he iti iho i te 50ms te wā whakawhiti parenga, e whakapai ake ana i te pono o te whatunga.
Tautoko ana i te whakahaere whatunga atanga whakairoiro, hanga anō i ngā rohe whakahaere ahokore me te tuku, ā, ka taea te aroturuki katoa i te mana o te kōwae whatu me te raina.
Ka tautokohia e ngā taputapu WDM hohe i te tari matua ngā kōwhiringa tuku hiko AC 220V me DC -48V, te tiakitanga whakauru hiko 1+1, ā, kāore te rahunga hiko o ngā taputapu e pā ki te tuku pakihi.
He āheinga whakatakoto ā-waho, he ngāwari hoki ngā wāhi whakatakoto o te WDM mamao
Te horopaki tono
Te whakatutuki i ngā hiahia o ngā horopaki whatunga CRAN pito-ki-pito, ko te tawhiti i waenga i ngā pae DU me AAU kei roto i te 10km
I ngā wāhi he iti noa ngā rauemi muka whatu, kāore he rauemi paipa, ā, ka whakatakotoria ngā muka whatu hou me te kore herenga.
Hangaia he whatunga ratonga matua kounga teitei hei tautoko i ngā hiahia pakihi pono-teitei o te 5G.
