Yuav ua li cas tiv thaiv nas thiab xob laim nyob rau sab nraum zoov optical cables?Nrog rau qhov muaj koob meej ntawm 5G tes hauj lwm, qhov ntsuas ntawm sab nraum zoov kho qhov muag cable npog thiab rub tawm kho qhov muag cables tau txuas ntxiv.Vim hais tias qhov ntev-ntev optical cable siv optical fiber los txuas cov chaw nres tsheb hauv paus, lub hauv paus chaw nres tsheb thiab chaw nres tsheb hauv chaw ua haujlwm tau txuas nrog ntawm qhov deb ntawm 100-300 meters, kom lawv tsis txhob raug mob los ntawm nas thiab xob laim.Yog li ntawd, qhov teeb meem ntawm nas thiab xob laim tiv thaiv ntawm qhov ntev-ntev optical cable yog qhov tseem ceeb heev.Tab sis tib lub sijhawm, xav txog kev ua haujlwm ntawm kev tiv thaiv nas thiab tiv thaiv xob laim, nws kuj yog qhov nyuaj dua.
nws txoj haujlwm dav dav los tiv thaiv nas yog muab cov hlau armor tub rau ntawm qhov chaw taws teeb kho qhov muag rau hauv nws, ib qho yog tsim los muab cov tub rog tub rog rau hauv txheej sab hauv ntawm lub tsho cable, thiab lwm qhov yog tsim los muab cov tub rog armor. sab nraum lub tsho Pem teb.Txawm li cas los xij, cov tub rog armored tuaj yeem ua hluav taws xob, thiab tom qab xob laim tawm tsam rau hauv cov pej thuam tso tawm, nws tuaj yeem tau txais los ntawm cov khoom siv kho qhov muag, yog li rhuav tshem cov elongated optical fiber ntau thiab txawm ua rau hluav taws.
Nyob rau hauv cov lus teb rau qhov no, steel armor yog ntxiv rau lub kho qhov muag cable sheath, thiab ib tug saj zawg zog hlau yog ntxiv rau cov khoom tiv thaiv xob laim tiv thaiv xob laim.Txiav cov fiber ntau sab nraud rau lub voj voog raws li cov kev taw qhia radial, tom qab ntawd snap lub nplhaib conductive rau hauv txoj haujlwm incision, tom qab ntawd siv cov kua nplaum rau qhov kev txiav txim siab rau kev sib txuas thiab kev sib khi, thiab tom qab ntawd ntxiv ib lub raj hlau rau txheej txheej rau kev tiv thaiv.Nyob rau hauv txoj kev no, lub high-voltage arc generated los ntawm xob laim tiv thaiv ntaus ntawv yog absorbed los ntawm armored raj, thiab ib tug hluav taws xob tam sim no generated.Anti-rat, tiv thaiv xob laim hauv tsev thiab sab nraum zoov fiber ntau optic cable hloov tau yooj yim tuaj yeem xa cov khoom siv tam sim no rau hauv av, yog li txo thiab zam qhov kev puas tsuaj los ntawm xob laim rau cov khoom siv kho qhov muag.
