Tuam Tshoj yog cov neeg siv khoom loj ntawm fiber ntau optic cables, tab sis tsis yog cov neeg siv khoom muaj zog ntawm fiber ntau optic cables. Tam sim no, txawm hais tias Tuam Tshoj txoj kev lag luam cable muaj qib siab ntawm kev siv lub peev xwm, muaj teeb meem ntawm cov khoom siv tsis sib haum xeeb. Cov lag luam feem ntau yog siv cov khoom siv qis-nqi-ntxiv nruab nrab- thiab qis-voltage cables. Lawv cov txuj ci kev noj qab haus huv tau qhia ntau dhau, kev sib tw ua lag luam hnyav, thiab cov nyiaj tau los Qhia txog kev poob qis, thaum cov khoom siv high-end thiab ultra-high-voltage cable cia siab rau kev xa khoom. Xyoo 2009, Tuam Tshoj tau xa tawm 281,900 tons ntawm fiber ntau optic cable cov khoom, nrog rau tus nqi ntshuam ntawm US $ 3.676 billion. Piv nrog rau xyoo 2004, tus naj npawb ntawm imports poob los ntawm 72,900 tons, tab sis tus nqi ntshuam nce los ntawm US $ 1.301 billion. Raws li cov ntaub ntawv los ntawm General Administration ntawm kev lis kev cai, thaum lub sij hawm "Tsib Hlis Tsib Hlis Ntuj Plan" lub sij hawm, qhov nruab nrab nqi tsev (nqi ib chav tsev qhov hnyav) ntawm imported cable khoom nyob rau hauv Tuam Tshoj yog kwv yees li ob npaug rau chav tsev nqi ntawm export khoom. Kev nqis peev hauv Tuam Tshoj txoj kev siv hluav taws xob siab thiab ultra-high-voltage hluav taws xob yog nce, tab sis feem ntau cov tuam txhab cable hauv Suav teb muaj teeb meem rau kev siv cov khoom lag luam uas xav tau los ntawm kev ua lag luam, uas tau dhau los ua kev sib tw loj rau kev lag luam cable.
Raws li kev txheeb cais los ntawm qee lub koom haum, muaj ntau txog 7,000 cov tuam txhab loj thiab me fiber-optic cable hauv Suav teb, suav nrog cov lag luam me thiab nruab nrab. Kev ua lag luam ntawm cov tuam txhab no tsuas yog 1% -2.5%. Raws li cov ntaub ntawv los ntawm National Bureau of Statistics, kev ua lag luam sib koom ntawm 19 lub tuam txhab cable hauv Suav teb thaum kawg ntawm 2009 suav tsuas yog 11.7% ntawm tag nrho cov kev lag luam, thaum peb lub tuam txhab Asmeskas sab saum toj muaj kev lag luam ntawm 54% hauv lawv lub tsev. lub teb chaws, thiab xya lub tuam txhab Nyij Pooj saum toj kawg nkaus suav rau 86% ntawm kev lag luam, 95% ntawm 12 lub tuam txhab cable saum toj kawg nkaus hauv UK. Cov txiaj ntsig ncaj qha ntawm cov lag luam loj thiab cov kev lag luam qis qis yog qhov poob ntawm kev lag luam cov nyiaj tau los thiab ntau lub peev xwm. Kev hloov kho thiab kev koom ua ke ntawm kev lag luam fiber optic cable yog qhov tseem ceeb.
