Munthawi ya 5G, ma module owoneka amabwereranso kukula pamsika wamatelefoni

Kumanga kwa 5G kudzayendetsa kukula kwachangu kwa kufunikira kwa ma modules optical for telecommunications.Potengera zofunikira za 5G optical module, zimagawidwa m'magawo atatu: fronthaul, midhaul, ndi backhaul.

5G kutsogolo: 25G / 100G optical module

Maukonde a 5G amafunikira masiteshoni apamwamba kwambiri / kachulukidwe ka malo a cell, motero kufunikira kwa ma module othamanga kwambiri kwakula kwambiri.25G / 100G optical modules ndi njira yabwino yothetsera ma network a 5G fronthaul.Popeza eCPRI (mawonekedwe owonjezereka a wailesi ya kanema) mawonekedwe a protocol (chiwerengero chodziwika bwino ndi 25.16Gb / s) amagwiritsidwa ntchito potumiza zizindikiro za baseband za 5G base stations, 5G fronthaul network idzadalira kwambiri 25G optical modules.Ogwira ntchito akugwira ntchito mwakhama kukonzekera zomangamanga ndi machitidwe kuti athandize kusintha kwa 5G.Pachimake, mu 2021, msika wapakhomo wa 5G wofunikira wa Optical module ukuyembekezeka kufika RMB 6.9 biliyoni, ndi ma module a 25G opangira 76.2%.

Poganizira malo ogwiritsira ntchito kunja kwa 5G AAU, 25G Optical module yomwe imagwiritsidwa ntchito pa intaneti ya fronthaul iyenera kukwaniritsa kutentha kwa mafakitale -40 ° C mpaka + 85 ° C ndi zofunikira zopanda fumbi, ndi kuwala kwa 25G ndi kuwala kwa mtundu. ma modules adzatumizidwa molingana ndi mapangidwe osiyanasiyana a fronthaul omwe amagwiritsidwa ntchito mu maukonde a 5G.

25G grey optical module ili ndi zowonjezera zowonjezera zowonjezera, choncho ndiyoyenera kwambiri kulumikiza kwa fiber optical point-to-point optical fiber.Ngakhale njira yolumikizira mwachindunji ya fiber optical ndi yosavuta komanso yotsika mtengo, siyingakwaniritse ntchito zowongolera monga chitetezo chamaneti ndi kuyang'anira.Chifukwa chake, sichingapereke kudalirika kwakukulu kwa mautumiki a RLLC ndipo imadya zinthu zambiri za fiber fiber.

25G color optical modules imayikidwa makamaka mu WDM yogwira ntchito ndi maukonde a WDM / OTN, chifukwa amatha kupereka maulendo angapo a AAU ku DU pogwiritsa ntchito fiber imodzi.Yankho la WDM lopanda pake limagwiritsa ntchito zinthu zochepa za fiber, ndipo zida zopanda pake ndizosavuta kuzisamalira, komabe sizingakwaniritse kuwunika kwa maukonde, chitetezo, kasamalidwe ndi ntchito zina;yogwira WDM/OTN imasunga zida za fiber ndipo imatha kukwaniritsa ntchito za OAM monga magwiridwe antchito apamwamba komanso kuzindikira zolakwika, ndikupereka chitetezo chamaneti.Ukadaulo uwu mwachilengedwe umakhala ndi mawonekedwe a bandwidth yayikulu komanso kuchedwa kochepa, koma choyipa ndichakuti mtengo womanga maukonde ndi wokwera kwambiri.

Ma 100G optical modules amaonedwanso kuti ndi imodzi mwa njira zopangira ma fronthaul network.Mu 2019, ma module a 100G ndi 25G akhazikitsidwa ngati makhazikitsidwe okhazikika kuti apitilize kukula mwachangu kwa malonda ndi ntchito za 5G.Pamawonekedwe a fronthaul omwe amafunikira kuthamanga kwambiri, 100G PAM4 FR / LR optical modules akhoza kutumizidwa.The 100G PAM4 FR / LR optical module ikhoza kuthandizira 2km (FR) kapena 20km (LR).

Kutumiza kwa 5G: 50G PAM4 Optical module

Ma network a 5G apakati opatsirana ali ndi zofunikira za 50Gbit / s optical modules, ndipo ma module amtundu wa imvi ndi mtundu amatha kugwiritsidwa ntchito.The 50G PAM4 QSFP28 optical module pogwiritsa ntchito LC optical port ndi single-mode fiber imatha kuwirikiza bandwidth kudzera mu ulalo wa fiber single-mode popanda kukhazikitsa fyuluta yogawa mafunde ambiri.Kupyolera mu DCM yogawidwa ndi BBU malo amplification, 40km ikhoza kufalitsidwa.Kufunika kwa ma module a 50G optical makamaka amachokera pakumanga maukonde onyamula 5G.Ngati maukonde onyamula 5G alandiridwa kwambiri, msika wake ukuyembekezeka kufika mamiliyoni ambiri.

5G backhaul: 100G/200G/400G Optical module

Ma network a 5G backhaul adzafunika kunyamula magalimoto ambiri kuposa 4G chifukwa chapamwamba kwambiri komanso bandwidth yapamwamba 5G NR wailesi yatsopano.Choncho, gawo la convergence ndi core layer ya 5G backhaul network ili ndi zofunikira za DWDM color optical modules ndi liwiro la 100Gb / s, 200Gb / s, ndi 400Gb / s.The 100G PAM4 DWDM optical module imayikidwa makamaka mu gawo lofikira ndi convergence layer, ndipo imatha kuthandizira 60km kudzera mu T-DCM yogawana ndi optical amplifier.Kutumiza kwapakati kumafunikira mphamvu yayikulu komanso mtunda wautali wa 80km, kotero 100G/200G/400G ma module ophatikizika a DWDM amafunikira kuti athandizire network ya metro core DWDM.Tsopano, chinthu chofunikira kwambiri ndi kufunikira kwa netiweki ya 5G kwa ma module a 100G.Othandizira amafunikira 200G ndi 400G bandwidth kuti akwaniritse zomwe zimafunikira pakutumiza kwa 5G.

Pakatikati mwa kufalitsa ndi zochitika za backhaul, ma modules optical amagwiritsidwa ntchito nthawi zambiri m'zipinda zamakompyuta zomwe zimakhala ndi kutentha kwabwino, kotero kuti ma modules opangira malonda angagwiritsidwe ntchito.Pakalipano, mtunda wodutsa pansi pa 80km makamaka umagwiritsa ntchito 25Gb / s NRZ kapena 50Gb / s, 100 Gb / s, 200Gb / s, 400Gb / s PAM4 optical modules, ndi maulendo aatali pamwamba pa 80km adzagwiritsa ntchito ma modules optical ( chonyamulira chimodzi 100 Gb/s ndi 400Gb/s).

Mwachidule, 5G yalimbikitsa kukula kwa msika wa 25G/50G/100G/200G/400G Optical module.
