FIBER OPTIC CABLING Tsis muaj kev cuam tshuam los ntawm hluav taws xob nrov (EMI, RFI, thiab xob laim), fiber ntau optic cabling muab ntau yam, muaj kev ntseeg siab heev ntawm kev nthuav dav kev sib txuas lus. Nws tuaj yeem siv rau hauv thaj chaw uas muaj cov tshuab tig, arc vuam, thiab lwm yam, thiab tuaj yeem ntsia tau rau hauv cov tais cable uas muaj cov kab hluav taws xob muaj zog, lossis nyob rau sab nraum zoov uas muaj kev phom sij. Nws cov yam ntxwv ntawm kev sib cais hluav taws xob muab kev tiv thaiv los ntawm qhov sib txawv ntawm qhov sib txawv thiab cov voj hauv av. Fiber optic cable siv nyob rau hauv qhov kev teeb tsa no yog yuav los ntawm cov neeg siv khoom. Qhov pom zoo fiber ntau optic cable yog multimode, graded-index iav fiber ntau nrog 62.5 micron core thiab 125 micron cladding nrog 0.275 NA (tus lej aperture). Qhov siab tshaj plaws tso cai teeb liab poob yog 1 dB ib km ntawm lub wavelength ntawm 1300 nm, thiab 3.6 dB ib km ntawm lub wavelength ntawm 850 nm. Cables nrog cov yam ntxwv sib txawv yuav tsis siv. Plaub fiber ntau optic cables yuav tsum muaj rau redundancy, ob rau kis thiab ob rau tau txais kev sib txuas. Vim li no, nws raug nquahu kom cov neeg siv khoom yuav ob lub cabling, uas muaj ob lub fibers intertwined hauv ib lub cable. Cov cables yuav tsum raug txiav nrog ST-type connectors thiab cable ntev yuav tsis pub tshaj qhov uas tau teev tseg rau lub module. Lwm yam kev xav tau ntawm cable (xws li yoog raws, lossis kev ua haujlwm ntev) nyob ntawm cov ntawv thov tshwj xeeb. Tshawb xyuas nrog koj tus neeg muag khoom cable / installer rau cov npe ntawm daim ntawv thov tshwj xeeb cable yam ntxwv. FCM10Ef MODULE DESIGN FCM10Ef modules hloov 2 Mbps signals siv los ntawm FBMs, mus rau 10 Mbps fiber optic Ethernet signals siv nrog fiber ntau optic cabling, thiab vice versa. FCM10Ef modules muaj cov qauv tsim qauv, nrog rau cov rugged extruded aluminium sab nrauv rau kev tiv thaiv lub cev ntawm cov circuits. Cov ntaub thaiv tshwj xeeb uas tsim los rau kev txhim kho ntawm FBMs thiab FCMs muab ntau theem ntawm kev tiv thaiv ib puag ncig rau FCM10Ef modules, mus txog qhov hnyav ib puag ncig ntawm ISA Standard S71.04. FCM10Ef tuaj yeem raug tshem tawm / hloov ntawm lub hauv paus phaj yam tsis tau tshem tawm lub zog. Rau lub teeb-emitting diodes (LEDs) muab tso rau hauv pem hauv ntej ntawm FCM10Ef qhia cov xwm txheej ntawm kev ua haujlwm hauv network rau / los ntawm FBMs cuam tshuam, thiab FCM10Ef module txoj haujlwm ua haujlwm.
