 Chii chinonzi cascade FTTH kutumirwa neakaomeswa mhando yekubatanidza?

Cascade FTTH Deployment: A Pfupi Pfupi Fiber kuImba (FTTH) network yakakosha pakupa yakakwirira-inomhanya internet kuwana zvakananga kunzvimbo dzekugara uye dzebhizinesi. Iyo dhizaini yeFTTH network inokanganisa zvakanyanya kuita kwayo, mutengo, uye scalability. Imwe sarudzo yakakosha yekuvaka inosanganisira kuiswa kwemaoptical splitters, ayo anotarisisa kuti munetiweki iyo fiber yakakamurwa.

Centralized vs. Cascaded Architectures- Centralized Approach:

1. Munzira yepakati, imwe-nhanho splitter (kazhinji 1x32 splitter) inoiswa muhubhu yepakati (yakadai sefiber distribution hub kana FDH).
2. Hub inogona kuwanikwa chero pane network.
3. Iyo 1x32 splitter inobatanidza zvakananga kuGPON (Gigabit Passive Optical Network) Optical Line Terminal (OLT) muhofisi yepakati.
4. Kubva pakupatsanurwa, 32 fibers inoendeswa kumisha yevatengi vega, kwavanobatana neOptical Network Terminals (ONTs).
5. Ichi chivakwa chinobatanidza imwe OLT port kusvika 32 ONTs.

Cascaded Approach:

1. Munzira ye cascaded, multi-stage splitters (yakadai se 1x4 kana 1x8 splitters) inoshandiswa mumuti-uye-branch topology.
2. Semuenzaniso, 1x4 splitter inogona kugara kunze kwechirimwa chakavharirwa uye ichibatanidza zvakananga kune OLT port.
3. Imwe neimwe yemafibhi ina inosiya iri danho rekutanga kupatsanurwa inofambiswa kune yekupinda terminal imba 1x8 stage 2 splitter.
4. Muchiitiko ichi, huwandu hwe32 fibers (4x8) inosvika 32 dzimba.
5. Zvinogoneka kuve nezvinhanho zvinodarika zviviri zvekupatsanura muhurongwa hwecascade, huine mareshiyo akasiyana-siyana (semuenzaniso, 1x16, 1x32, 1x64).

Benefits uye Zvinofungidzirwa- Centralized Nzira:

1. Zvakanakira:

• Kureruka: Zvikamu zvishoma zvinopatsanura zvinorerutsa kugadzirwa kwetiweki.

• Kubatanidza zvakananga: Chiteshi chimwe cheOLT chinobatana kune akawanda ONT.

2. Cons:

• Fiber zvinodiwa: Inoda imwe fiber nekuda kwekubatanidza zvakananga.

• Mutengo: Mutengo wepamusoro wekutanga wekutumira.

• Scalability: Kashoma scalability kupfuura 32 vatengi.

-Cascaded Nzira:

1.Pros:

• Fiber kunyatsoshanda: Inoda zvishoma fiber nekuda kwebazi.

• Mutengo-kubudirira: Kuderera kwekutanga kwekutumira mari.

• Scalability: Zviri nyore scalable kune vakawanda vatengi.

2. Cons:

• Kuoma: Multiple splitter matanho anowedzera kuoma.

• Kurasikirwa kwechiratidzo: Chinhanho chega chega chinopatsanura chinounza kumwe kurasikirwa.

Yakaomeswa Type Connectors muFTTH Deployment- Akaomeswa majoini anoita basa rakakosha muFTTH deployments:

1. Vanobvisa kudiwa kwekubatanidza, kurerutsa kuiswa.
2. Vanoderedza unyanzvi hwokugadzira hunodiwa nekushanda.
3. Vanokurumidzira uye vanogadzirisa kutumirwa, vachisangana nezvinodiwa zvekuchinja uye kwakavimbika network.
