IOLM ndi chiyani?

Intelligent Optical Link Mapping (iOLM) ndi ukadaulo womwe umasinthiratu njira yosinthira OTDR kuti igwire ndikusanthula zidziwitso zonse pa ulusi mosasamala kutalika kwake komanso kuchuluka kwa zolumikizira ndi ma splices patali.

Pali magawo awiri, kapena "ma level", omwe amapezeka potsimikizira ma fiber optic cabling.
Chitsimikizo choyamba ndi muyeso wa kutayika kwathunthu (komwe kale kunkatchedwa attenuation) kwa cabling kuchokera kumapeto kwa ulalo kupita kwina, Chitsimikizo chachiwiri chimapereka chidziwitso chotayika pagawo lililonse la ulalo.

OTDR (optical time domain reflectometer) imagwiritsidwa ntchito popanga chiphaso chachiwiri. Ubwino waukulu wa mayeso achiwiri a certification ndikuti umapereka chidziwitso chokhudzana ndi kulumikizana kulikonse, splice ndi gawo la chingwe mu ulalo ndipo limapereka chiwonetsero chazithunzi za zigawozo ndi momwe amagwirira ntchito.

Pamene kuyezetsa kumene anaika cabling lipoti ndi chithunzithunzi cha dongosolo kuti tingayerekezere mayeso pambuyo kuzindikira kusintha kulikonse mu cabling. OTDR ndiyopanda vuto kuti ithetse mavuto chifukwa imawonetsa woyendetsa ndendende pomwe zolakwika zili mu cabling, ndikufulumizitsa kukonza.

Pulse Width imakhudza kwambiri zotsatira za kuyeza, kutalika kwa pulse ndi nthawi ya laser pulse pa chitsanzo chilichonse panthawi yopeza. Kuthamanga kwafupipafupi kumapereka kusintha kwabwino kwambiri ndipo kumatha kuzindikira zochitika zomwe zili pafupi ndi zigamba zomwe pangakhale mapazi ochepa pakati pa zolumikizira. Chotsalira cha kugunda kwachidule ndikuti amalowetsa mphamvu zochepa mu cabling ndipo sangathe kuyeza mtunda wautali. Nthawi zina, OTDR ikhoza kulephera kuzindikira kutha kwa chingwe ngati pali zogawa zotayika kwambiri pa ulalo monga zomwe zimagwiritsidwa ntchito mu PONs (passive optical network).

Kuchulukitsa kuchuluka kwa pulse kumapereka mphamvu zambiri zoyezera zingwe zazitali kapena "kukhomerera" kudzera pazigawo zomwe zingasowepo zolumikizira kapena zolumikizira mu ulalo. Kuti ayese ulalo bwino, katswiri amatha kuyesa mayeso angapo, iliyonse ili ndi kuchuluka kwamphamvu kosiyanasiyana kotero kuti zolumikizira ndi ma splices pafupi ndi kumapeto kwa chingwe zitha kuyezedwa komanso kutalika kwa chingwe kuti ifike kumapeto. kuyeza kwa kutaya.

Kunyengerera
Pamapeto pake, kupeza njira yabwino, imodzi ya OTDR ya chingwe chopatsidwa ndi nkhani yosokoneza yomwe imafika pakutha (kuthwa) motsutsana ndi kusintha kwamphamvu (kutaya kwakukulu komwe kungayesedwe). M'mbuyomu, ntchito yokhayo inali kupanga malipoti angapo pamtundu uliwonse ndi OTDR yokhazikitsidwa pamasinthidwe osiyanasiyana.

Kuyesa kumodzi kukanachitidwa ndi kugunda kwafupipafupi kuti muyese molondola zolumikizira za munthu aliyense pafupi ndi OTDR ndipo wina amayendetsedwa ndi utali wautali wa pulse kuti apereke mphamvu yokwanira yoyezera kupyola pazigawo ndikuwona njira yonse mpaka kumapeto kwa zingwe zazitali. Kenaka, mayesero omwewo amachitidwa pamtunda wachiwiri kuti macrobends (makhoma olimba kapena kinks) adziwike ndikusiyanitsidwa ndi ma splices chifukwa kutayika kwa bend kumadalira kutalika kwa wavelength komwe kutayika kwa splice sikuli.

Pogwiritsa ntchito njirayi pakhoza kukhala malipoti anayi kapena kuposerapo pamtundu uliwonse woyesedwa. Ngakhale njira iyi imajambula zonse zokhudzana ndi zochitika zosiyanasiyana pa ulusi, kuyesa kumvetsetsa zonse kuti muwone ngati ulusi umadutsa kapena kulephera si ntchito yaing'ono. Osatchulanso nthawi yomwe imafunika kukonzanso OTDR pamayesero aliwonse osiyanasiyana omwe amawononga zokolola za akatswiri olipidwa kwambiri.

iOLM Imathandizira Kusanthula kwa OTDR
Intelligent Optical Link Mapping (iOLM) ndi ukadaulo womwe umasinthiratu njira yosinthira OTDR kuti igwire ndikusanthula zidziwitso zonse pa ulusi mosasamala kutalika kwake komanso kuchuluka kwa zolumikizira ndi ma splices patali. Pogwiritsa ntchito iOLM, OTDR idzachita mayesero angapo pogwiritsa ntchito masinthidwe osiyanasiyana ndikuphatikiza zonse zomwe zimachokera ku lipoti limodzi lomwe limapatsa wogwiritsa ntchito zotsatira zosavuta za PASS / FAIL ngakhale zolumikizira zovuta kwambiri.

Ngakhale OTDR yokhala ndi ukadaulo wa iOLM imatha kupanga njira yachikhalidwe ya OTDR kwa iwo omwe akufuna, chinsinsi chothandizira kusanthula kwa OTDR ndichokusintha momwe timawonera zotsatira za mayeso a OTDR. M'malo motsatira zomwe zimafunikira zaka zambiri zakumunda kuti zitanthauzire, iOLM imapanga chojambula chofananira pogwiritsa ntchito zithunzi zosavuta kuzimvetsetsa kuti ziyimire zolumikizira, ma splices, splitters, macrobends ndi zochitika zina pa ulusi womwe ukuyesedwa. Izi zimalola katswiri yemwe alibe chidziwitso chogwiritsa ntchito ma OTDR kuti atsimikizire ma fiber cabling ndikumvetsetsa zomwe zikuchitika pamayeso aliwonse.

Kwa zingwe zabwino zomwe zimadutsa muyeso womwe mukufuna, chochitika chilichonse chidzayimiridwa ndi chithunzi chobiriwira chozindikiritsa mtundu wa chochitika ndi nambala yomwe ili pamwamba ndi pansi pa bokosi lomwe likuwonetsa mtunda ndi kutaya mphamvu kwa chochitikacho.

Mayeso akalephera, chochitikacho chidzayimiridwa ndi chithunzi chofiira chokhala ndi mtunda ndi kutayika, komanso malingaliro amomwe mungakonzere vutoli. Ndi iOLM, katswiri amatha kuzindikira mwachangu komanso mosavuta, kupeza ndi kukonza zovuta pa ulalo uliwonse wa fiber mosasamala kanthu za zovuta zake.

BAUDCOMOTDR3000 Series,OTDR5000 SeriesndiOTDR900 Series all have good IOLM function, which smartly test the fiber function.

Ndidafunikira iwo kuti alumikizane ndi PC yanga pa chipinda chachitatu kuti ndikhale ndi intaneti mchipinda chimenecho, ndipo ISP idayika modemu yawo pa chipinda choyamba chokha. Pambuyo poponya zingwe zama fiber, zolumikizidwa ndi zingwe zonse muzosinthira izi mbali zonse, ndipo ulalo udatuluka pomwepo. Zinali zosavuta kuposa momwe ndimaganizira!
