Indian kho qhov muag thiab cov kev daws teeb meem lub tuam txhab STL tshaj tawm tias nws tau tsim lub ntiaj teb thinnest telecom optical fiber - 160-micron optical fiber. Ashwini Vaishnaw, Is Nrias teb tus Minister of Communications, Electronics, Information Technology thiab Railways, tau nthuav tawm cov khoom lag luam hauv ntiaj teb no ntawm STL lub rooj muag khoom ntawm 7th.India Mobile Communications Conference(IMC 2023).
Tom qab tso tawm 160-micron fiber, tus thawj coj "spliced" los yog "sib koom" ob strands - ib tug heev calibrated txheej txheem uas zoo kawg nkaus txuas cov cores ntawm ob plaub hau nyias fibers.
Raws li cov lus ceeb toom, cables ua los ntawm STL's 160-micron optical fiber tuaj yeem ua kom muaj peev xwm 3 npaug ntau dua li ib txwm siv 250-micron optical fiber. Nws tau txais kev xav thiab tsim nyob rau hauv-tsev ntawm STL's Center of Excellence hauv Indian xeev Maharashtra, ua STL yog ib lub tuam txhab thawj zaug hauv ntiaj teb los tsim thiab patent rau kev lag luam ua lag luam.
Is Nrias teb tab tom tshwm sim los ua lub ntiaj teb kev lag luam digital loj tshaj plaws thiab xav tau kev xa tawm fiber ntau optic network. Tso cov conduits account rau kwv yees li 60% ntawm tag nrho cov nqi xa tawm fiber ntau, ua qhov chaw txuas rau qhov khoom muaj nqis. Cov neeg tsim khoom lag luam thoob plaws ntiaj teb tab tom nrhiav kom txo cov fiber ntau kom haum ntau thiab ntau lub peev xwm rau hauv qhov chaw muaj duct.
STL's 160-micron fiber packs muaj peev xwm ntau dua rau hauv qhov chaw qis qis thiab txo cov kab hluav taws xob los ntawm 6.4 mm (kwv yees li 32% txo qis piv rau 250-}micron fiber), uas yuav hloov pauv kev xa tawm network, bandwidth muaj peev xwm, thiab ib puag ncig tus phooj ywg. . Qhov cuam tshuam loj ntawm qhov kev tsim kho tshiab no rau Is Nrias teb qhov chaw dav dav tuaj yeem loj heev. Piv txwv li, nyob rau hauv ib txoj haujlwm loj xws li Bharatnet, qhov twg Is Nrias teb yuav tsum xa txog 20 lab mais ntawm fiber ntau optic cables los ntawm 2025, siv 160-micron fiber ntau hloov tus qauv 250-micron fiber ntau tuaj yeem txo qis kev xa mus. lub sijhawm kwv yees li 15%. Qhov no ua rau siv cov kav dej me me, uas ua rau kwv yees li 30% tsawg dua cov yas hauv av.
Dr. Badri Gomatam, Chief Technology Officer ntawmSTL Group, hais tias: "Qhov no thinnest optical fiber ntau yog ib qho tseem ceeb ntawm txoj kev loj hlob thiab qhia peb kev cog lus rau innovation thiab peb tsis tu ncua kev tshawb fawb thiab kev loj hlob zog nyob rau hauv lub teb ntawm photonics thiab cov ntaub ntawv science."
Qhov kev txo qis ntawm cov tub ntxhais kho qhov muag fiber ntau txoj kab uas hla yog qhov nyuaj uas tau ntes cov kev xav ntawm cov kws kho qhov muag thoob ntiaj teb. Qee qhov kev sib tw tseem ceeb hauv kev txo qis fiber ntau hauv qab 250 microns suav nrog kev txhim kho rhiab heev rau microlending thiab nce qhov nyuaj ntawm cov txheej txheem fiber ntau.
Hais txog kev daws cov teeb meem no, Dr. Badri tau hais ntxiv tias: "Los ntawm cov txheej txheem thiab cov khoom siv engineering, peb tau ua tiav cov txheej txheem tsim khoom thiab cov iav sib xyaw kom ua tiav micro khoov-insensitive kev ua tau zoo."
Cov khoom no ua tau raws li cov qauv kev ua haujlwm kho qhov muag thiab ua raws li ITU G. 657A2 tus qauv. Qhov no ua raws li kev tsim kho tshiab los ntawm lub tuam txhab R&D cov kws tshaj lij, suav nrog Is Nrias teb thawj 4x muaj peev xwm multi-core optical fiber ntau thiab 180-micron optical fiber.
Ankit Agarwal, Tus Thawj Coj ntawm STL, tau hais tias: "Qhov kev tsim kho tshiab hauv av no qhia txog peb txoj kev mob siab rau coj Indian thev naus laus zis thiab R&D rau lub ntiaj teb. ."
