Yintoni umahluko phakathi kwe-OM kunye ne-OS2 iintambo zefiber optic?

Iintambo zeFiber optic zidlala indima ebalulekileyo kulwakhiwo lothungelwano lonxibelelwano, zimbini iindidi zeentambo eziqhelekileyo zefiber optic kwimarike. Enye ikwimowudi enye kwaye enye ine-multi-mode fiber optic cable. Ngokuqhelekileyo imowudi eninzi ixhotyiswe nge "OM(Optical multi-mode fiber)" kwaye imowudi enye ixhonywe nge "OS(Optical single-mode fiber)".

Kukho iintlobo ezine zeendlela ezininzi: i-OM1, i-OM2, i-OM3 kunye ne-OM4 kunye ne-Single-mode ineentlobo ezimbini ze-OS1 kunye ne-OS2 kwimigangatho ye-ISO / IEC 11801. Yintoni umahluko phakathi kwe-OM kunye ne-OS2 iintambo zefiber optic? Koku kulandelayo, siya kwazisa umahluko phakathi kweentlobo ezimbini zeentambo.

1.Umahluko kwidayimitha engundoqokunye neentlobo zefiber

Iintambo ze-OM kunye ne-OS zinokumahluko omkhulu kwidayamitha engundoqo. Iimowudi ezininzi zefiber core idayamitha yi-50 µm kunye ne-62.5 µm ngokwesiqhelo, kodwa i-OS2-imowudi enye yedayamitha engundoqo yi-9 µm.

2.Umahluko wokuthomalalisa

Ukucuthwa kwentambo ye-OM iphezulu kunentambo ye-OS, ngenxa yobukhulu bedayamitha engundoqo. Intambo ye-OS inedayamitha engundoqo emxinwa, ngoko isiginali yokukhanya inokudlula kwifayibha ngaphandle kokubonakaliswa kumaxesha amaninzi kwaye igcine i-atenuation isezantsi. Kodwa intambo ye-OM inomthamo omkhulu we-fiber core, okuthetha ukuba iya kuphulukana namandla okukhanya ngakumbi ngexesha lokuhanjiswa komqondiso wokukhanya.

 

3. Umahluko kumgama

Umgama wokuhanjiswa kwefayibha ye-single-mode ayikho ngaphantsi kwe-5km, esetyenziswa ngokubanzi kumgca wonxibelelwano olude; ngelixa i-fiber ye-multi-mode inokufikelela kuphela malunga ne-2km, kwaye ifanelekile kunxibelelwano olufutshane kwizakhiwo okanye kwiikhampasi.

Uhlobo lweFayibha		Umgama
		I-100BASE-FX	1000BASE-SX	1000BASE-LX	1000BASE-SR	40GBASE-SR4	100GBASE-SR10
Imowudi enye	OS2	200M	5KM	5KM	10KM	-	-
Iimowudi ezininzi	OM1	200M	275M	550M (Ifuna intambo yokulungiswa kwemowudi)	-	-	-
	OM2	200M	550M		-	-	-
	OM3	200M	550M		300M	100M	100M
	OM4	200M	550M		400M	150M	150M

 

4. Umahluko kubude bobude kunye nomthombo wokukhanya

Thelekisa intambo ye-OS, intambo ye-OM inomthamo ongcono "wokuqokelela ukukhanya". Ubungakanani obukhulu be-fiber core buvumela ukusetyenziswa kwemithombo yokukhanya ephantsi kwexabiso eliphantsi, njenge-LED kunye ne-VCSEL esebenza kwi-850nm kunye ne-1300 nm wavelengths. Ngelixa intambo ye-OS isebenza ikakhulu kwi-1310 okanye i-1550 nm wavelengths efuna imithombo yelaser ebiza kakhulu.

5. Umahluko kwi-bandwidth

Intambo ye-OS ixhasa ukukhanya kunye nemithombo yokukhanya yamandla ngakumbi kunye nokuthomalalisa okusezantsi, ibonelela nge-bandwidth engenamkhawulo. Ngelixa intambo ye-OM ixhomekeke ekuhanjisweni kweendlela ezininzi zokukhanya ezinokukhanya okuncinci kunye nokuthomalalisa okuphezulu okunika umda kwi-bandwidth.

6. Umahluko kwi-sheath yombala wentambo

Jonga kwi-TIA-598C inkcazo eqhelekileyo, intambo ye-OS yemowudi enye idla ngokugqunywa ngebhatyi yangaphandle etyheli, ngelixa intambo eneendlela ezininzi eqatywe ngombala orenji okanye we-aqua.
