Qhov Kev Ntsuas Qhov Tseem Ceeb: Los ntawm 100G Plateaus mus rau 800G Frontiers

Ib txwm txha nraub qaum- nplooj ntoo, feem ntau ua nrog duplex LC lossis SC txuas, ntsib qhov tawg ntawm 400G thiab dhau mus. Tus naj npawb ntawm cov fibers xav tau rau kev sib txuas optics tuaj yeem cuam tshuam kev tswj hwm cable thiab qhov chaw khib. Cov lus teb zoo yog nyob rau hauv kev lag luam wholesale hloov mus rau cov qauv, siab - ntom fiber optic thaj vaj huam sib luag thiab MPO / MTP- raws li cabling ecosystems.

Ib qho 400G-SR8 module, piv txwv li, siv 16-fiber MPO-16 connector (8 fibers rau kis, 8 rau tau txais). Kev xa tawm ntau txhiab qhov kev sib txuas nrog cov khoom siv duplex yog qhov tsis tuaj yeem siv tau. Niaj hnub nimno high-density fiber ntau thaj panels, xws li 2U los yog 4U units txhawb 96, 144, los yog ntau dua qhov chaw nres nkoj suav, yog engineered los tswj qhov ceev no. Lawv tsis yog passive enclosures tab sis active Cheebtsam ntawm lub cable tswj lub tswv yim, tsim los nrog tshwj xeeb khoov vojvoog tswj, clear labeling pathways, thiab robust strain nyem.

Qhov tseeb innovation yog nyob rau hauv cov ntsiab lus hloov pauv. MTP/MPO lub cev cables- ua ntej- txiav cov hlua nrog MPO txuas ntawm ob qhov kawg - tsim kom huv si, cov pob txha caj qaum txuas ntawm cov vaj huam sib luag. MTP rau LC breakout cables ces muab cov kiv cua tseem ceeb - tawm mus txuas rau ib tus neeg hloov chaw nres nkoj lossis servers. Qhov kev hloov pauv no, tau lees paub hauv kev xa tawm los ntawm cov chaw muab huab cua loj, txo lub sijhawm teeb tsa los ntawm 70% piv rau kev txiav tawm ib txwm ua haujlwm thiab txo qis qhov kev pheej hmoo ntawm kev ua tau zoo- degradating khoov lossis tsis zoo splices.

Kev xeem 2024 los ntawm Ethernet Alliance tau pom tias ua ntej -tawm MPO-12 txog 6xLC breakout system rau 400G-SR4.2 daim ntawv thov khaws cia tsis tu ncua kev poob qis hauv qab 0.35 dB ib khub niam txiv, ntsib thiab tshaj IEEE 802.3bs specifications Qhov kev xaiv ntawm fiber ntau optic thaj vaj huam sib luag teeb tsa rau ultra-siab ceev piv rau ib qho tseem ceeb dua kev kho dua tshiab yog qhov tseem ceeb ua lag luam ua lag luam-tawm; ntau dua ntom ntom feem ntau tuaj ntawm tus nqi ntawm me ntsis ntxiv lub sij hawm rov kho dua.

Kev ua tau zoo ntawm cov khoom siv optics yog qhov kawg ntawm qhov zoo thiab cov yam ntxwv ntawm cov nroj tsuag tsis muaj fiber ntau. Rau intra-cov ntaub ntawv chaw nyob sab hauv tsev fiber ntau optic cables, hloov mus rau 400G / 800G tau cemented OM5 wideband multimode fiber (WBMMF) thiab OS2 ib leeg-mode fiber (SMF) raws li cov xov xwm tseem ceeb. OM5 fiber ntau, nrog rau nws txuas ntxiv bandwidth ntawm 850-950nm wavelengths, txhawb 400G-SR4.2 tshaj 100m thiab tau npaj los txhawb 800G-SR8 tshaj 70m, muab tus nqi-kev ua tau zoo{20} luv luv sab saum toj - ntawm-rack (ToR) rau nplooj ntawv txuas.

Txawm li cas los xij, rau txhua qhov txuas dhau 100-150m, lossis rau yav tom ntej- pov thawj tiv thaiv 1.6T thiab cov thev naus laus zis sib txuas, OS2 ib hom fiber ntau yog qhov tsis meej, yog tias kim dua me ntsis, xaiv.

Nws zoo li tsis muaj kev txwv bandwidth thiab qis attenuation ua rau nws tsuas yog qhov nruab nrab siv tau rau txha nraub qaum-rau- qaum thiab sab hauv- kev txuas hauv tsev kawm ntawv. Kev tsim kab hluav taws xob nws tus kheej yog qhov tseem ceeb. Tsawg-kev sib txhuam hauv tsev cable nrog du, qis- pa taws xoom-halogen (LSZH) lub tsho yog qhov tseem ceeb rau siab - ntim, siab- khoov kev teeb tsa hauv cov tais ntim khoom siv. Rau cov chaw zov me nyuam nrog cov kev sib txuas sab nraud lossis cov tsev kawm ntawv loj, kev xaiv ntawm sab nraum zoov fiber ntau optic cable yog qhov sib npaug.

Sab nraum zoov armored fiber optic cable muab cov nas tseem ceeb thiab tsoo tsis kam rau faus ncaj qha, thaum ADSS sab nraum zoov cable (Txhua tus -Dielectric Tus Kheej-Txhawb nqa) yog tsim los rau kev xa tawm dav hlau yam tsis muaj xov tooj sib cais. Lub attenuation specification rau cov ntev -haul fibers yog qhov tseem ceeb; hwm OS2 cables tam sim no niaj hnub ua tiav 0.16 dB / km ntawm 1550nm, ib daim duab uas txhais ncaj qha mus rau lub suab nrov ntev dua thiab cov nqi qis dua.

Raws li cov chaw zov me nyuam tau hloov mus rau ntau qhov kev faib tawm, ntug- paub txog architectures, cov pob txha fiber ntau yuav tsum tau txhawb nqa passive optical LAN (POL) thiab saib xyuas cov txheej txheem hauv qhov chaw. Ntawm no, PLC splitters ua lub luag haujlwm tseem ceeb.

Tsis zoo li yav dhau los fused biconical taper (FBT) thev naus laus zis, PLC (Planar Lightwave Circuit) splitters, xws li compact 1x8 PLC splitter lossis 1x2 PLC splitter modules, muaj kev ua tau zoo sib xws, qis polarization- nyob ntawm qhov poob (<0.1 dB), and a wider operating temperature range (-40°C to 85°C). They are integrated into splitter cassette units within the main distribution area (MDA) to enable a single transceiver to broadcast signals to multiple endpoints for management or security systems. The integrity of every connection point is non-negotiable.

The move to higher speeds has made return loss (RL) specifications for fiber optic connectors drastically more stringent. While UPC (Ultra Physical Contact) connectors with a typical RL of >50 dB tau tsim nyog rau 10G, 400G thiab 800G systems, tshwj xeeb tshaj yog cov uas siv PAM4 kev hloov kho, feem ntau xav tau SC APC lossis LC APC connectors.

The angled physical contact (APC) polish provides a RL of >60 dB, txo qhov cuam tshuam lub suab nrov uas tuaj yeem ua rau qhov nyuaj PAM4 daim duab duab. Txoj kev teeb tsa kuj pom kev tsim kho tshiab, nrog cov khoom sib txuas ceev ceev (tseem hu ua teb- cov khoom txuas tau nruab) ua rau ntawm -site, cuab yeej- tsawg dua nrog kev tso tawm tsis ua haujlwm tam sim no rivaling Hoobkas- polished connectors (<0.3 dB), a crucial factor for rapid repairs and scaling in hyper-scale environments.
