Cov txheej txheem kev tsim kho ntawm cov kab kho qhov muag dav dav feem ntau yog muab faib ua tsib theem: kev npaj, tso, kev sib txuas, kev sim thiab kev lees paub tiav.
① Ib leeg-reel tshuaj xyuas ntawm cov khoom siv kho qhov muag: xyuas qhov zoo ntawm cov kab hluav taws xob kho qhov muag, cov yam ntxwv cuam tshuam ntawm fiber ntau thiab cov teeb liab kab, thiab lwm yam.
② Routing re-test: Raws li kev tsim qauv tsim duab kos duab, tshuaj xyuas cov kev taw qhia tshwj xeeb ntawm cov routing, nteg tej yam kev mob, ib puag ncig tej yam kev mob thiab qhov chaw tshwj xeeb ntawm kev sib koom tes, hauv av deb, faib, faib, thiab lwm yam.
③ Optical cable tis: Nws yog los xam tag nrho cov nteg ntev raws li txoj kev retest thiab tsim nyog xaiv qhov optical cable reel ntev.
4. Routing npaj: cov yeeb nkab tu, pre-txheej hlau hlau los yog pre-ntev yas conduits ua ntej nteg optical cables, pre-ntev steel hlau ropes thiab hooks ua ntej overhead nteg, excavation ntawm optical cable trenches ua ntej ncaj faus nteg, teeb tsa cov qhov sib koom ua ke. , thiab lwm yam. Nws yuav pab txhawb qhov kev vam meej ntawm txoj haujlwm thiab kev nyab xeeb ntawm cov khoom siv kho qhov muag.
⑤ Optical cable nteg: Raws li txoj kev tso, dai ib leeg-disk kho qhov muag cable khib rau ntawm tus ncej lossis rub nws mus rau hauv cov yeeb nkab, lossis muab tso rau hauv qhov kho qhov muag cable trench.
⑥ Optical fiber cable txuas kev teeb tsa: suav nrog kev sib txuas ntawm fiber ntau, tooj liab, aluminium sheath, kev sib txuas ntawm cov tub ntxhais muaj zog, thiab ntsuas kev sib koom ua ke. Lub encapsulation ntawm lub tes tsho sib koom tes thiab kev txhawb nqa ntawm kev tiv thaiv kev sib koom tes, thiab lwm yam.
⑦ Relay ntsuas: suav nrog cov yam ntxwv ntawm cov khoom siv fiber ntau (xws li tag nrho cov attenuation ntawm optical fiber, thiab lwm yam) kuaj thiab tooj liab hlau hluav taws xob kev xeem, thiab lwm yam.
⑧ Kev lees txais tiav ntawm cov kab hluav taws xob kho qhov muag: Muab cov ntaub ntawv xws li kev tsim cov duab kos, kho cov duab kos duab thiab ntsuas cov ntaub ntawv, thiab ua haujlwm zoo ntawm kev tshuaj xyuas ntawm qhov chaw thiab ua tiav kev lees paub, txhawm rau muab cov kab hluav taws xob tsim nyog thiab xyuas kom muaj kev ua haujlwm ntawm lub xaib. qhov system.
