FTTH Imikorere ihanitse FBT fibre optique itandukanya

Ibisobanuro bigufi:

FBT nuburyo bugufi bwa Fused Biconic Taper splitter, ishingiye ku buhanga gakondo, guhuza hamwe fibre ebyiri cyangwa nyinshi za optique, hanyuma ugakurura imashini ya cone yashonga irambuye, hamwe nigihe gikurikirana ihinduka ryikigereranyo, ibisabwa byikigereranyo. nyuma yo gushonga kurambura, uruhande rumwe rugumana fibre imwe (ahasigaye gukata) nkiyinjiza, urundi ruhande ni umuyoboro mwinshi usohoka.

Ibisobanuro ku bicuruzwa

Nka kimwe mu bintu by'ingenzi bigize imiyoboro ya GPON FTTx, ibice bya optique bishobora gushyirwa mu biro bikuru cyangwa muri kimwe mu bigabanywa (hanze cyangwa mu nzu) kubera ko abafatanyabikorwa ba FBT bahagaze neza cyane ku bimenyetso byinshi bya optique bigabanywa hamwe no gutakaza igihombo gito.Ihuriro rya FBT ryagenewe kugabana amashanyarazi no gukanda mubikoresho byitumanaho, umuyoboro wa CATV, nibikoresho byo gupima.

Ibiranga ibicuruzwa

1. Guhuza neza no gutakaza kwinjiza bike
2. Igihombo gito gishingiye ku gihombo
3. Umukanishi mwiza
4. Ibidukikije bikora: -40ºC kugeza + 85ºC
5. Igipimo kinini cyo kuzimangana & Uniformity nziza
6. Fibre yinjiza: 0.9mm cyangwa 250μm fibre yo guhitamo
7. Ibisohoka bya fibre: 250μm fibre yambaye ubusa (Ninyungu yo gutera) G.657A Fibre

Ibicuruzwa

1. Fibre kugeza aho (FTTX)

2. Fibre murugo (FTTH)

3. Imiyoboro ya optique ya pasiporo (PON, GEPON)

4. Imiyoboro y'akarere (LAN)

5. Televiziyo y'insinga (CATV)

6. Ibikoresho byo gupima
