Fibre y'uburyo bumwe: G652D vs G657A2

1/ Fibre imwe ni iki?

+ Fibre y’uburyo bumwe ni fibre y’urumuri yagenewe gutwara uburyo bumwe gusa bw’urumuri - uburyo bwo kunyuranamo.

+ Fibre optique isanzwe ifite umurambararo w'ibanze uri hagati ya μm 8 na 10.5 (ubusanzwe ni μm 9) n'umurambararo w'ipfundo wa μm 125.

+ OS1 na OS2 ni fibre optique isanzwe ya 9/125 μm ifite uburyo bumwe. Byombi bikoreshwa hamwe n'uburebure bw'umurambararo bwa 1310 nm na 1550 nm.

+ Fibre y’uburyo bumwe yagenewe kohereza ubutumwa mu ntera ndende kandi yihuta cyane, akenshi ishyigikira intera iri hagati ya kilometero 2 na kilometero 100–160.

+ Imiterere ya fibre isanzwe y’uburyo bumwe:

Ishingiro:Umwanya wa 8–9 μm

Igipfundikizo:Umurambararo wa 125 μm

Buffer:250 μm umurambararo

Ikoti:Umwanya wa 600 cyangwa 900 μm

2/ G652D Fiber y'uburyo bumwe:

+ G652D Fiber y'uburyo bumwe ni yo ikunze gukoreshwa cyane muri fibre optique isanzwe (SMF), isanzwe ikoreshwa na ITU-T mu gutumanaho ryihuse kandi rikora intera ndende.

+ Ifite ikoranabuhanga rya "low water peak", rigabanya igihombo cy'amajwi mu rugero rwa 1383 nm.

+ Izwiho kuba ifite umuyoboro munini w'itumanaho, igabanya cyane imikorere, kandi ikaba ijyanye n'imikorere yayo inyuma, ni nziza cyane ku miyoboro y'itumanaho, Metropolitan Area Networks (MAN), na Fiber to the Home (FTTH).

3/ G657A2 Fiber y'uburyo bumwe:

+ G.657A2 Fiber y'uburyo bumwe ni fibre idafata umugozi cyane, ikurikiza amahame ya ITU-T, yakozwe kugira ngo ikore neza kandi nta kimenyetso kinini gitakara ku ntera yo gupfundika cyane (hasi nka 7.5mm).

+ Irahuye neza na fibre ya G.652D, bigatuma iba nziza cyane ku nsinga za FTTH zifite ubucucike bwinshi, insinga zo mu nzu, hamwe n'ibikoresho bito kandi bifite umwanya munini.
