Ni irihe tandukaniro riri hagati ya OM na OS2 fibre optique insinga？

Umugozi wa fibre optique ugira uruhare runini mukubaka imiyoboro yitumanaho, hari ubwoko bubiri bwinsinga za fibre optique kumasoko.Imwe ni moderi imwe naho ubundi ni fibre optique ya fibre optique.Mubisanzwe uburyo-bwinshi bwashyizwe hamwe na "OM (Optical multi-mode fibre)" naho uburyo bumwe bwashyizwe hamwe na "OS (Optical single-mode fibre)".

Hariho ubwoko bune bwuburyo bwinshi: OM1, OM2, OM3 na OM4 hamwe nuburyo bumwe bufite ubwoko bubiri bwa OS1 na OS2 mubipimo bya ISO / IEC 11801.Ni irihe tandukaniro riri hagati ya fibre optique ya OM na OS2?Mubikurikira, tuzamenyekanisha itandukaniro riri hagati yubwoko bubiri bwinsinga.

1.Itandukaniro muri diameter yibanzen'ubwoko bwa fibre

Imiyoboro ya OM na OS ifite itandukaniro rinini muri diameter yibanze.Ubwoko bwa fibre yibikoresho byinshi ni 50 µm na 62.5 µm mubisanzwe, ariko OS2 imwe-yuburyo bumwe busanzwe bwa diameter ni 9 µm.

Ibikoresho byiza bya fibre yibanze

Ubwoko bwa fibre

    

 

2.Itandukaniro muri attenuation

Kwiyongera kwa kabili ya OM irarenze umugozi wa OS, kubera diameter nini yibanze.Umugozi wa OS ufite diameter yibanze, bityo ibimenyetso byurumuri birashobora kunyura muri fibre bitagaragaye inshuro nyinshi kandi bigakomeza atenuation byibuze.Ariko umugozi wa OM ufite fibre nini ya fibre nini bivuze ko izatakaza ingufu nyinshi zumucyo mugihe cyohereza ibimenyetso.

 

3. Itandukaniro riri kure

Intera yoherejwe ya fibre imwe-fibre ntabwo iri munsi ya 5km, isanzwe ikoreshwa kumurongo wogutumanaho kure;mugihe fibre yuburyo bwinshi ishobora kugera kuri 2km gusa, kandi irakwiriye itumanaho rigufi mumazu cyangwa mumashuri.

Ubwoko bwa fibre		Intera
		100BASE-FX	1000BASE-SX	1000BASE-LX	1000BASE-SR	40GBASE-SR4	100GBASE-SR10
Uburyo bumwe	OS2	200M	5KM	5KM	10KM	-	-
Uburyo bwinshi	OM1	200M	275M	550M (Ukeneye uburyo bwo gutondekanya umugozi)	-	-	-
	OM2	200M	550M		-	-	-
	OM3	200M	550M		300M	100M	100M
	OM4	200M	550M		400M	150M	150M

 

4. Itandukaniro muburebure bwumurongo & Inkomoko yumucyo

Gereranya na kabili ya OS, umugozi wa OM ufite ubushobozi "bwo gukusanya urumuri".Ingano nini ya fibre nini itanga ikoreshwa ryumucyo uhendutse, nka LED na VCSELs ikora kuri 850nm na 1300 nm yumuraba.Mugihe insinga ya OS ikora cyane kuri 1310 cyangwa 1550 nm yumurambararo usaba isoko ya laser ihenze cyane.

5. Itandukaniro mugari

Umugozi wa OS ushyigikira urumuri rwinshi kandi rwinshi rwumucyo hamwe na attenuation yo hasi, itanga umurongo utagira umupaka.Mugihe insinga ya OM yishingikiriza kumurongo wurumuri rwinshi rufite umucyo muke hamwe na attenuation yo hejuru itanga imipaka kumurongo.

6. Itandukaniro mubyuma byamabara

Reba kuri TIA-598C ibisobanuro bisanzwe, umugozi umwe wa OS usanzwe ushyizwe hamwe na jacket yo hanze yumuhondo, mugihe umugozi wuburyo bwinshi wasizwe na oragen cyangwa ibara rya aqua.
