Kuona, Kuona Nzvimbo, uye Kubata Nzvimbo Dzakanyanya Kudzikira Mumatambo Emagetsi

Mukugadzirwa kwetambo dzeoptical, kushanda kwekudzikisa tambo inzira inokosha yekuongorora. Zvichibva pamamiriro ezvinhu emutsetse wenguva dzose, chinyorwa chino chinoongorora nzvimbo uye nzira dzekubata nadzo nzvimbo dzekudzikisa tambo dzeoptical.

I. Nzvimbo Dzinowanzoonekwa Dzenzvimbo Dzinodzikamisa Zvinhu Zvikuru

Mushure mekupedza kusanganisa tambo, bvunzo yeOTDR inowanzoitwa pachikamu chose cherelay. Bvunzo iyi inoongorora kana hunhu hwe optical hwetambo yakasanganiswa huchienderana nezvinodiwa zvekuvaka uye mwero wekugamuchirwa. Ongororo iyi inonyanya kusanganisira:

• Kana kuderedzwa kwese kwechikamu cherelay kwakaderera pane zvakatsanangurwa pakugadzira (kureva kuti, kana avhareji yekudzikiswa kweavhareji inosangana nezvinodiwa)

• Kana avhareji yekurasikirwa kwemajoini nepakati pezvikamu zviviri ichisangana nezvinodiwa zvekugamuchirwa uye zvinodiwa pakugadzira

• Kana mutsetse wekumashure wakatsetseka wakafanana uye wakatsetseka, pasina matanho makuru ekudzikamisa kunze kwematanho madiki anokonzerwa nekurasikirwa kwakajairika kwezvikamu

Paunenge uchishandisa OTDR kuyedza chikamu cherelay uye kuwana nzvimbo dzine attenuation yakakwira, zvakakosha kugadzirisa nemazvo ma parameter akadai se range, wavelength, pulse width, refractive index, uye averaging time:

• Rudzi rwekuyedza:Gadzirisa zvinoenderana nehurefu hwechikamu cherelay kuitira kuti curve itore chikamu che2/3 chechiratidziro chekuratidzira

• Kureba kwemafungu:Kazhinji 1310 nm uye 1550 nm patambo dzekutakura tambo dziri kure

• Chiratidzo cheRefractive:Seti yacho yakavakirwa pazvinodiwa nemugadziri wefaibha

• Kufara kwemoyo:Chinhu chakakosha—chidiki kwazvo chinoita kuti pave nekushanduka-shanduka kusina kukwana uye ma curve ane ruzha; chikuru kwazvo chinoderedza kunyatsojeka kwekuyera. Chinofanira kusarudzwa zvichienderana nezvinodiwa zvedaro uye kunyatsojeka.

• Avhareji yenguva:Gadzirisa kusvika muswe wakakombama wanyatsonaka pasina ruzha runoonekwa

Kuti uwane nzvimbo dzekukanganisa nemazvo, software yekuongorora yeOTDR inogona kushandiswa. Zvikanganiso zvinowanzoiswa muzvikamu zviviri: zvikanganiso zve splice-box uye zvikanganiso zve cable-body.

II. Kubata Nzvimbo Dzinodzikira Zvikuru

Kutanga, tarisa kana nzvimbo yekudzikamisa yakanyanya iri panzvimbo ye splice. Pama splice points, fiber dzese dzinowanzo ratidza matanho ekudzikamisa akasiyana-siyana. Nekuongorora ma fiber curves akawanda panguva imwe chete, kana ma curves ese achiratidza matanho panzvimbo imwe chete, zvingangoita kuti idambudziko re splice.

• Chiyera uye verenga kurasikirwa kwe splice kwemativi maviri panguva iyoyo

• Nyora chero hunhu hunopfuura mwero

• Vhura chivharo che splice woita zviito zvekugadzirisa

Kana mamwe mafiber achiratidza kuderera kwesimba panzvimbo imwe asi mamwe asingaratidzi, dambudziko ringangodaro risiri rekubatana asi kutadza kuri mukati memuviri wetambo.

Nzira dzeKukanganisa Nzvimbo

• Zvikanganiso zvepedyo:Shandisa OTDR kubva paterminal kuyera daro kubva panzvimbo iri pedyo ye splice

• Zvikanganiso zvekupedzisira:Nekuda kwekusanyatsorurama kwenzvimbo refu, edza kubva pakuvhara kwe splice iri pedyo panzvimbo pezvo.

• Sanganisa data reOTDR nezvinyorwa zvekuvaka uye ruzivo rwekusashanda zvakanaka

• Ita zviyero zvemunda kuti uwane dambudziko mukati memamita angangoita gumi

Maitiro aya anoderedza huwandu hwekuchera, anoderedza mari, uye anopfupisa nguva yekugadzirisa.

Nzira dzekugadzirisa

1. Zvikanganiso zveSplice-Point

• Vhura kuvhara kwe splice uye batanidzazve fibers

• Tarisa panguva chaiyo uchishandisa OTDR kusvika mazinga ekurasikirwa agamuchirwa asvika

Kana kudzokorora kusanganisa zvinhu zvikatadza kushanda:

• Tarisa kana machubhu e fiber buffer akashanduka

• Iva nechokwadi chekuti nharaunda yekukotama yakakodzera panguva yekukombama kwefiber

• Tarisa kana fiber iri kudzvanywa

Kana matambudziko akaramba aripo, tarisa zvikamu zvetambo usati waisa tambo uye mushure meyo. Kana zvichifungidzirwa kuti kukuvara kwacho kwakaitika, cheka wobva waisa tambo dzese patsva.

2. Zvikanganiso zveMuviri weCable

Zvikonzero zvinowanzo sanganisira:

• Kukwenya kana kumonyoroka kwetambo

• Kukuvadzwa kwekunze kwemuchina (semuenzaniso, kumanikidzwa kubva kumatombo kuchikonzera kushanduka kwechinhu)

• Kushanduka kwechubhu yebuffer kunotungamira mukumanikidzwa kwefiber

Mhinduro:

• Cheka chikamu chakakuvara wobva wabatanidzazve

• Kana kukuvara kwakanyanya, isa chivharo che splice wogadzirisa shinda dzakakanganiswa

• Kana zvichidikanwa, bvisa sheath yekunze wogadzirisa kana kutsiva machubhu ebuffer akakuvara

Matanho ekudzivirira

• Tarisa kureba kwetambo yekuwedzera usati wabatanidza

• Cheka kureba kwakawedzerwa kubva kumagumo etambo anofungidzirwa kuti usakuvara

• Siya diki yakakwana panzvimbo dzinozivikanwa dzisina simba kuti zvive nyore kugadzirisa mune ramangwana

Zvinodiwa paKuyedza

Vashandi vekuyedza vanofanirwa kushanda pamwe chete nematekiniki emumunda uye kuita bvunzo dzeOTDR pamatanho anotevera:

1. Mushure mekunge kubatanidzwa kwapera

2. Mushure mekunge fiber coil yapera

3. Mushure mekuvharwa kwechikamu chekuvhara

Chikwata chinobva panzvimbo iyi mushure mekusimbisa kuti matambudziko ekudzikisa zvinhu agadziriswa.
