Cov kev cai rau kev tsim kho qhov muag cable yog qhov yooj yim thiab kev ntseeg tau. Raws li cov yam ntxwv ntawm optical cables, cov ntsiab lus hauv qab no yuav tsum tau ua kom ntseeg tau:
nruj me ntsis tswj qhov nro thov rau cov optical fibers thaum lub sij hawm unwinding thiab winding los xyuas kom meej tias cov fibers tsis tawg thaum lub sij hawm tsim cov txheej txheem, thiab hais tias qhov kev nyuaj siab thiab residual kev nyuaj siab ntawm cov fibers yog txo.
nruj me ntsis tswj microbending attenuation tshwm sim los ntawm cov neeg kho tshuab sab nraud thaum lub sij hawm tsim cov txheej txheem los xyuas kom meej tias nws tsis cuam tshuam rau kev sib kis ntawm cov fibers optical.
Xaiv cov txheej txheem yas extrusion tsim nyog kom tsis txhob muaj microbending attenuation tshwm sim los ntawm kev ua tsis zoo thiab cov yas tom qab tshav kub shrinkage, kom ntseeg tau ntev -lub sij hawm ruaj khov kis tau tus mob ntawm cov optical cable.
Cov txheej txheej ntawm cov kab hluav taws xob kho qhov muag txhim kho nws cov kev tiv thaiv rau sab nraud thiab lub zog tensile, nrog rau kev muab cov dej noo thiab sealing. Tam sim no, muaj yim yam tseem ceeb ntawm optical cable sab nrauv sheath qauv hauv Suav teb:
Yooj yim polyethylene sheath (PE sheath) qauv.
Aluminium / polyethylene composite longitudinally qhwv thiab bonded sheath (LAP) qauv.
Corrugated steel daim kab xev longitudinally qhwv thiab sib tshooj nrog PE sheath qauv.
Aluminium / polyethylene composite longitudinally qhwv thiab bonded sheath ntxiv rau corrugated steel daim kab xev sib tshooj ntxiv rau PE sheath overlap.
Aluminium / polyethylene composite longitudinally qhwv thiab bonded sheath ntxiv rau steel daim kab xev longitudinal wrapping ntxiv rau PE sheath overlap.
Aluminium / polyethylene composite longitudinally qhwv thiab bonded sheath ntxiv rau corrugated steel daim kab xev longitudinal wrapping ntxiv rau PE sheath overlap.
Aluminium / polyethylene composite longitudinally qhwv thiab bonded sheath ntxiv rau steel hlau armor ntxiv rau PE sheath overlap.
Aluminium tube / armor / PE sheath composite sheath qauv.
