Gutahura, kumenya aho ibintu biri no gucunga aho ibintu bikura cyane mu nsinga z'amashanyarazi

Mu kubaka insinga z'amashanyarazi, imikorere yo kugabanya ingufu ni igipimo cy'ingenzi cy'isuzuma. Hashingiwe ku miterere isanzwe y'umurongo, iyi nkuru isesengura ahantu n'uburyo bwo gucunga ingingo zigabanya ingufu cyane mu nsinga z'amashanyarazi.

I. Ahantu hakunze kugaragara ahantu hanini ho guhagarara

Nyuma yo kurangiza guhuza insinga, ikizamini cya OTDR gikunze gukorwa ku gice cyose cyo guhuza insinga. Iki kizamini cyemeza niba imiterere y'urumuri rw'insinga ifatanye ihuye n'ibipimo by'ubwubatsi n'amahame yemewe. Isuzuma rikubiyemo ahanini:

• Niba uburyo bwo kugabanya umubare w'ibikoresho byo kugabanya umubare w'ibikoresho byo kugabanya umubare w'ibikoresho (ni ukuvuga niba uburyo bwo kugabanya umubare w'ibikoresho byo kugabanya umubare w'ibikoresho by'ibikoresho by'ikoranabuhanga buhuye n'ibisabwa)

• Niba igipimo cy’impuzandengo y’ingingo zombi z’imfuruka z’ingingo z’imfuruka cyujuje ibisabwa n’imiterere y’ingingo.

• Niba umusemburo w'inyuma ugororotse ungana kandi woroshye, nta ntambwe nini zo kugabanya umuvuduko keretse intambwe nto ziterwa no gutakaza ibice bisanzwe

Mu gihe ukoresha OTDR kugira ngo ugerageze igice cyo gusimbuza no kubona ingingo zo kugabanya cyane, ni ngombwa gushyiraho neza ibipimo nk'urugero, uburebure bw'umurambararo, ubugari bw'amajwi, igipimo cyo kugarura ubushyuhe, n'igihe cyo gupima:

• Ingano y'igerageza:Shyiraho hakurikijwe uburebure bw'igice cyo gusimbuza ku buryo umugozi ufata hafi 2/3 by'ishusho ya ecran

• Uburebure bw'umuraba:Ubusanzwe 1310 nm na 1550 nm ku nsinga zo mu bwoko bwa trunk zikoreshwa kure

• Igipimo cy'ikirahure:Ishyirwaho rishingiye ku bisobanuro by'uruganda rukora fibre

• Ubugari bw'impeshyi:Igipimo cy'ingenzi—kito cyane gituma habaho intera idahagije y'impinduka n'imirongo isakuza; kinini cyane kigabanya uburyo bwo gupima. Kigomba gutoranywa hashingiwe ku ntera n'ibisabwa ku buryo bunonosoye.

• Igihe mpuzandengo:Hindura kugeza igihe umurizo w'inyuma ugororotse nta rusaku rugaragara

Kugira ngo hamenyekane neza aho amakosa ari, porogaramu ya OTDR irashobora gukoreshwa. Amakosa muri rusange agabanywa mu byiciro bibiri: amakosa ya splice-box na cable-body.

II. Gukemura Ingingo Zikomeye Zigabanya Ubukana

Ubwa mbere, menya niba aho igice cyo kugabanya cyane kiri ahantu ho kugabanya. Ku gice cyo kugabanya, imigozi yose ikunze kugaragaza intambwe zo kugabanya ku rugero rutandukanye. Mu gusesengura imigozi myinshi ya fibre icyarimwe, niba imigozi yose igaragaza intambwe ahantu hamwe, birashoboka ko ari ikibazo cya splice.

• Pima kandi ubare igihombo cya splice y'impande ebyiri kuri iyo ngingo

• Andika agaciro kose karenze ibipimo ngenderwaho

• Fungura ifunga ry'igice hanyuma ukore ibikorwa byo gukosora

Niba hari insinga zimwe na zimwe zigaragaza ko zigabanuka ahantu runaka mu gihe izindi zitagaragaza ko zigabanuka, ikibazo gishobora kuba atari agace gato ahubwo ari ikibazo kiri mu mubiri w'insinga.

Uburyo bwo Gushyira Ikosa mu Kantu

• Amakosa yo hafi:Koresha OTDR uvuye kuri terminal kugira ngo upime intera iri hagati y'aho splice iri hafi

• Amakosa akomeye cyane:Bitewe n'uko intera ndende idakora neza, gerageza ukoresheje agafunga k'agace kari hafi aho.

• Huza amakuru ya OTDR n'inyandiko z'ubwubatsi n'amakuru ajyanye n'igihe

• Gukora ibipimo by'umurima kugira ngo umenye aho ikibazo kiri mu ntera ya metero 10

Ubu buryo bugabanya ubucukuzi, bugabanya ikiguzi, kandi bugabanye igihe cyo gusana.

Uburyo bwo gusana

1. Amakosa yo mu gice kimwe

• Fungura ifunga ry'udusate hanyuma wongere ushyiremo udusate twose

• Genzura mu gihe nyacyo ukoresheje OTDR kugeza igihe igihombo cyemewe kigeze ku rugero rw'igihombo

Niba guhuza inshuro nyinshi binaniranye:

• Reba niba imiyoboro ya fibre buffer yahindutse

• Menya neza ko umurambararo ukwiye wo kugonda mu gihe cyo gufunga fibre

• Reba niba fibre ifunze neza

Niba ikibazo kikomeje, genzura ibice by'insinga mbere na nyuma yo kuziba. Niba ukeka ko byangiritse, gabanya hanyuma wongere uvange insinga zose.

2. Amakosa ku mubiri w'insinga

Impamvu zisanzwe zirimo:

• Kuziba cyangwa kuzunguruka kw'insinga

• Kwangirika kw'inyuma y'imashini (urugero, igitutu gituruka ku mabuye gitera kwangirika)

• Guhinduka k'umuyoboro wa buffer bigatuma habaho gukanda kwa fibre

Igisubizo:

• Kata igice cyangiritse hanyuma wongere ugishyiremo kabiri

• Ku byangiritse bikomeye, shyiramo agafunga k'udusimba hanyuma usane insinga zangiritse

• Niba ari ngombwa, kuraho agakoresho ko hanze hanyuma usane cyangwa usimbuze imiyoboro yangiritse

Ingamba zo kwirinda

• Reba uburebure bw'insinga zisigaye mbere yo kuzihuza

• Kata uburebure bw'insinga ziteye amakenga kugira ngo wirinde kwangirika ku buryo buhishe

• Siga agahenge gahagije ku ntege nke zizwi kugira ngo byoroshye gusana mu gihe kizaza.

Ibisabwa mu isuzuma

Abakora ibizamini bagomba gukorana n'abatekinisiye bo mu rwego rwo hejuru kandi bagakora ibizamini bya OTDR mu byiciro bikurikira:

1. Nyuma yo kurangiza gushyiramo ibice

2. Nyuma yo kurangiza gufunga fibre

3. Nyuma yo gufunga igice cy'imashini

Nyuma yo kwemeza ko ibibazo byo kugabanya ikibazo byakemutse, itsinda rigomba kuva aho rikorera.
