FIBER OPTIC CABLING Mosakhudzidwa ndi phokoso lamagetsi (EMI, RFI, ndi mphezi), fiber optic cabling imapereka njira zosunthika, zodalirika kwambiri zopititsira patsogolo mauthenga azizindikiro. Itha kugwiritsidwa ntchito m'malo okhala ndi makina ozungulira, zowotcherera arc, ndi zina zotero, ndipo zitha kuyikidwa m'ma tray a chingwe okhala ndi mizere yamagetsi okwera kwambiri, kapena m'malo akunja omwe akukumana ndi zoopsa zamphezi. Makhalidwe ake odzipatula amagetsi amapereka chitetezo ku kusiyana kwa magetsi ndi malupu apansi. Fiber optic cabling yomwe imagwiritsidwa ntchito pakukonza uku imagulidwa ndi kasitomala. Chingwe chovomerezeka cha fiber optic ndi multimode, grade-index fiber fiber ndi 62.5 micron core ndi 125 micron cladding ndi 0.275 NA (manambala aperture). Kutayika kwakukulu kovomerezeka ndi 1 dB pa km pamtunda wa 1300 nm, ndi 3.6 dB pa km pamtunda wa 850 nm. Zingwe zamitundu yosiyanasiyana sizingagwiritsidwe ntchito. Zingwe zinayi za fiber optic zimafunikira kuti ziwonjezeke, ziwiri zotumizira ndi ziwiri kuti zilandire kulumikizana. Pazifukwa izi, tikulimbikitsidwa kuti kasitomala agule duplex cabling, yomwe imakhala ndi ulusi uwiri wolumikizidwa mu chingwe chimodzi. Zingwezo ziyenera kuthetsedwa ndi zolumikizira zamtundu wa ST ndipo kutalika kwa chingwe sikungapitirire zomwe zafotokozedwa pa module. Zofunikira zina za chingwe (monga kusinthasintha, kapena kulimba) zimadalira kugwiritsa ntchito komweku. Yang'anani ndi wogulitsa chingwe/choyikira chingwe kuti mupeze mndandanda wazomwe mungagwiritse ntchito. Ma module a FCM10Ef MODULE DESIGN FCM10Ef amasintha ma siginecha 2 Mbps ogwiritsidwa ntchito ndi ma FBM, kukhala ma siginecha 10 Mbps a fiber optic Ethernet omwe amagwiritsidwa ntchito ndi ma fiber optic cabling, ndi mosemphanitsa. Ma module a FCM10Ef ali ndi mawonekedwe ophatikizika, okhala ndi aluminiyamu yolimba yakunja kuti atetezere mabwalo. Malo otchingidwa mwapadera kuti amangirire ma FBM ndi ma FCM amapereka magawo osiyanasiyana achitetezo cha chilengedwe kwa ma module a FCM10Ef, mpaka malo ovuta malinga ndi ISA Standard S71.04. FCM10Ef ikhoza kuchotsedwa / kusinthidwa kuchokera ku baseplate popanda kuchotsa mphamvu. Ma LED (light-emitting diode) asanu ndi limodzi ophatikizidwa kutsogolo kwa FCM10Ef akuwonetsa momwe netiweki imagwirira ntchito kupita/kuchokera ku ma FBM ogwirizana nawo, komanso momwe gawo la FCM10Ef limagwirira ntchito.
