Kodi pali kusiyana kotani pakati pa OM ndi OS2 fiber optic zingwe?

Zingwe za fiber optic zimagwira ntchito yofunika kwambiri pakumanga ma network olumikizirana, pali mitundu iwiri ya zingwe zodziwika bwino za fiber optic pamsika. Imodzi ndi single-mode ndipo ina ndi multi-mode fiber optic chingwe. Nthawi zambiri ma multi-mode amalembedwa ndi "OM (Optical multi-mode fiber)" ndipo single-mode imayikidwa ndi "OS (Optical single-mode fiber)".

Pali mitundu inayi yamitundu yambiri: OM1, OM2, OM3 ndi OM4 ndipo Single-mode ili ndi mitundu iwiri ya OS1 ndi OS2 mumiyezo ya ISO/IEC 11801. Kodi pali kusiyana kotani pakati pa zingwe za OM ndi OS2 fiber optic? M'munsimu, tiwonetsa kusiyana pakati pa mitundu iwiri ya zingwe.

1.Kusiyana kwapakati pakatindi mitundu ya fiber

Zingwe zamtundu wa OM ndi OS zimakhala ndi kusiyana kwakukulu pakati papakati. Multi-mode fiber core diameter ndi 50 µm ndi 62.5 µm nthawi zambiri, koma OS2 single-mode yodziwika bwino yapakati ndi 9 µm.

2.Kusiyana kwa kuchepa

Kutsika kwa chingwe cha OM ndikokwera kuposa chingwe cha OS, chifukwa cha mainchesi akulu. Chingwe cha OS chimakhala ndi mainchesi opapatiza, kotero chizindikiro chowunikira chimatha kudutsa ulusi popanda kuwonetsedwa nthawi zambiri ndikuchepetsa kuchepa. Koma chingwe cha OM chili ndi mainchesi akuluakulu a fiber core kutanthauza kuti chidzataya mphamvu yochulukirapo panthawi yotumizira ma siginecha.

 

3. Kusiyana kwa mtunda

Mtunda wotumizira wa fiber single-mode si ochepera 5km, womwe umagwiritsidwa ntchito panjira yolumikizirana mtunda wautali; pomwe ulusi wamitundu yambiri ukhoza kungofikira pafupifupi 2km, ndipo ndiyoyenera kulumikizana mtunda waufupi mnyumba kapena masukulu.

		100BASE-FX	Mtengo wa 1000BASE-SX	Mtengo wa 1000BASE-LX	1000BASE-SR	40GBASE-SR4	100GBASE-SR10
Njira imodzi	OS2	200M	5km pa	5km pa	10km pa	-	-
Multi-mode	OM1	200M	275M	550M (Mufuna chingwe chowongolera chowongolera)	-	-	-
	OM2	200M	550M		-	-	-
	OM3	200M	550M		300M	100M	100M
	OM4	200M	550M		400M	150M	150M

 

4. Kusiyana kwa kutalika kwa mawonekedwe & Gwero la Kuwala

Yerekezerani ndi chingwe cha OS, chingwe cha OM chili ndi mphamvu yabwino "yosonkhanitsa". Chingwe chokulirapo cha fiber chimalola kugwiritsa ntchito magetsi otsika mtengo, monga ma LED ndi ma VCSEL omwe amagwira ntchito pa 850nm ndi 1300 nm wavelengths. Ngakhale chingwe cha OS chimagwira ntchito pa 1310 kapena 1550 nm wavelengths zomwe zimafuna magwero okwera mtengo a laser.

5. Kusiyana kwa bandwidth

Chingwe cha OS chimathandizira magwero owala komanso ochulukirapo amagetsi okhala ndi kutsika kochepa, amapereka bandwidth yopanda malire. Pomwe chingwe cha OM chimadalira kutumiza kwa mitundu ingapo yowunikira ndikuwala pang'ono komanso kutsika kwambiri komwe kumapereka malire pa bandwidth.

6. Kusiyana kwa chingwe mtundu sheath

Onani matanthauzidwe okhazikika a TIA-598C , chingwe cha OS chokhala ndi single-mode nthawi zambiri chimakutidwa ndi jekete yachikasu yakunja, pomwe chingwe chamitundu yambiri chimakutidwa ndi mtundu wa oragen kapena aqua.
