 Dab tsi yog cascade FTTH xa tawm los ntawm hardened hom connectors?

Cascade FTTH Deployment: Cov Txheej Txheem Luv Luv Fiber rau Lub Tsev (FTTH) tes hauj lwm yog qhov tseem ceeb rau kev muab internet ceev ceev ncaj qha mus rau thaj chaw nyob thiab chaw lag luam. Lub architecture ntawm FTTH network cuam tshuam nws qhov kev ua tau zoo, tus nqi, thiab kev scalability. Ib qho kev txiav txim siab tseem ceeb ntawm kev tsim vaj tsev yog qhov kev tso kawm ntawm optical splitters, uas txiav txim siab qhov twg hauv lub network cov fiber ntau sib cais.

Centralized vs. Cascaded Architectures- Centralized Txoj Kev:

1. Nyob rau hauv lub centralized mus kom ze, ib tug ib-theem splitter (feem ntau yog ib tug 1x32 splitter) yog muab tso rau hauv ib tug central hub (xws li ib tug fiber faib hub los yog FDH).
2. Lub hub tuaj yeem nyob txhua qhov chaw hauv lub network.
3. Lub 1x32 splitter txuas ncaj qha mus rau GPON (Gigabit Passive Optical Network) Optical Line Terminal (OLT) hauv qhov chaw ua haujlwm hauv nruab nrab.
4. Los ntawm cov splitter, 32 fibers raug xa mus rau ib tus neeg siv khoom lub tsev, qhov chaw uas lawv txuas rau Optical Network Terminals (ONTs).
5. Cov qauv no txuas ib qho chaw nres nkoj OLT rau 32 ONTs.

Txoj Kev Cascaded:

1. Nyob rau hauv lub cascaded mus kom ze, multi-theem splitters (xws li 1x4 los yog 1x8 splitters) yog siv nyob rau hauv ib tug ntoo-thiab-txias topology.
2. Piv txwv li, 1x4 splitter yuav nyob rau hauv ib qho chaw cog sab nraud thiab txuas ncaj qha mus rau qhov chaw nres nkoj OLT.
3. Txhua ntawm plaub fibers tawm hauv theem no 1 splitter yog routed mus rau ib tug nkag mus davhlau ya nyob twg lub 1x8 theem 2 splitter.
4. Hauv qhov xwm txheej no, tag nrho 32 fibers (4x8) ncav cuag 32 lub tsev.
5. Nws muaj peev xwm muaj ntau tshaj li ob theem sib cais hauv cov txheej txheem cascaded, nrog rau qhov sib txawv ntawm qhov sib cais tag nrho (xws li 1x16, 1x32, 1x64).

Cov txiaj ntsig thiab kev txiav txim siab - Txoj hauv kev hauv nruab nrab:

1. Pros:

• Simplicity: Tsawg dua theem splitter ua kom yooj yim tsim network.

• Kev sib txuas ncaj qha: Ib qhov chaw nres nkoj OLT txuas rau ntau ONTs.

2. Cons:

• Cov kev xav tau ntawm fiber ntau: Yuav tsum muaj fiber ntau vim muaj kev sib txuas ncaj qha.

• Tus Nqi: Tus nqi pib xa tawm ntau dua.

• Scalability: Txwv scalability tshaj 32 tus neeg muas zaub.

- Cascaded Approach:

1.Pros:

• Fiber efficiency: Yuav tsum muaj fiber ntau tsawg vim yog branching.

• Tus nqi siv tau: txo tus nqi xa tawm thawj zaug.

• Scalability: Yooj yim scalable rau ntau tus neeg muas zaub.

2. Cons:

• Complexity: Ntau theem splitter nce complexity.

• Teeb liab poob: Txhua theem splitter qhia qhov poob ntxiv.

Hardened Type Connectors hauv FTTH Deployment- Hardened connectors ua lub luag haujlwm tseem ceeb hauv FTTH xa tawm:

1. Lawv tshem tawm qhov xav tau ntawm splicing, simplifying installation.
2. Lawv txo cov kev txawj ntse uas xav tau los ntawm kev ua haujlwm.
3. Lawv ua kom nrawm thiab ua kom yooj yim rau kev xa tawm, ua tau raws li qhov xav tau ntawm kev sib txuas yooj yim thiab txhim khu kev qha.

Rau qhov kev daws teeb meem no, Jera Line npaj plaub yam khoom uas muaj covMini module blockless PLC splitter, fiber optic sab hauv tsev txiav qhov (socket)., hardened pre-terminated patchcordthiabFiber optic hardened adapter SC hom. Txais tos kom nrhiav tau cov lus qhia ntxiv txog peb cov khoom.
