Ndeupi musiyano uripo pakati peOM neOS2 fiber optic tambo?

Fiber optic tambo dzinoita basa rakakosha mukuvaka nharembozha, kune marudzi maviri eakajairwa fiber optic tambo pamusika.Imwe ndeye-single-modhi uye imwe ine multi-modhi fiber optic tambo.Kazhinji multi-mode inotangwa ne "OM(Optical multi-mode fiber)" uye single-mode inotangwa ne "OS(Optical single-mode fiber)".

Kune marudzi mana ema-multi-mode: OM1, OM2, OM3 uye OM4 uye Single-mode ine marudzi maviri eOS1 uye OS2 muISO/IEC 11801 mitemo.Ndeupi musiyano uripo pakati peOM neOS2 fiber optic tambo?Mune zvinotevera, isu tichasuma musiyano pakati pemhando mbiri dzetambo.

1.Musiyano wepakati dhayamitauye fiber mhando

OM uye OS mhando tambo dzine mutsauko mukuru mupakati dhayamita.Multi-modhi faibha musimboti dhayamita i50 µm uye 62.5 µm kazhinji, asi OS2 imwe-modhi yakajairika dhayamita yepakati i9 µm.

2.Musiyano mukuderedza

Iyo attenuation yeOM tambo yakakwira kupfuura OS tambo, nekuda kwehukuru hwepakati dhayamita.OS tambo ine nhete yepakati dhayamita, saka chiratidzo chemwenje chinogona kupfuura nefiber pasina kuratidzwa kakawanda uye kuchengetedza atenuation iri shoma.Asi OM tambo ine hombe fiber core dhayamita zvinoreva kuti icharasikirwa nemagetsi emwenje panguva yekufambiswa kwechiratidzo chemwenje.

 

3. Musiyano uri kure

Iyo yekufambisa kureba kwe-single-mode fiber haisi pasi pe5km, iyo inowanzoshandiswa kune mutsara wekutaurirana kure;nepo multi-modhi faibha inogona kungosvika anenge 2km, uye inokodzera kupfupi-kutaurirana kupfupi muzvivakwa kana makampasi.

Fiber type		Distance
		100BASE-FX	1000BASE-SX	1000BASE-LX	1000BASE-SR	40GBASE-SR4	100GBASE-SR10
Single-modhi	OS2	200M	5KM	5KM	10KM	-	-
Multi-modhi	OM1	200M	275M	550M (inoda mode conditioning chigamba tambo)	-	-	-
	OM2	200M	550M		-	-	-
	OM3	200M	550M		300M	100M	100M
	OM4	200M	550M		400M	150M	150M

 

4. Musiyano muwavelength & Chiedza Chinobva

Enzanisa neOs tambo, OM tambo ine zvirinani "kuunganidza-chiedza" kugona.Iyo yakakura saizi fiber core inobvumira kushandiswa kweyepasi-inodhura magetsi masosi, senge maLED uye VCSEL anoshanda pa850nm uye 1300 nm wavelengths.Nepo OS tambo inonyanya kushanda pa1310 kana 1550 nm wavelengths izvo zvinoda anodhura zvakanyanya laser masosi.

5. Kusiyana kwebandwidth

OS tambo inotsigira kupenya uye kwakawanda magetsi magetsi masosi ane yakaderera attenuation, inopa theoretically unlimited bandwidth.Nepo OM tambo ichitsamira pakufambiswa kweakawanda mwenje modhi ine kupenya kushoma uye nepamusoro attenuation iyo inopa muganhu pabandwidth.

6. Kusiyana kwetambo ruvara sheath

Tarisa kune TIA-598C yakajairika tsananguro, singl-modhi OS tambo inowanzovharwa neyero rekunze bhachi, nepo akawanda-modhi tambo yakavharwa neoragen kana aqua ruvara.
