Mitengo yathu idzakhala yabwino komanso yopikisana chifukwa champhamvu zathu zopanga, ngakhale mitengo ingasinthe malinga ndi kupezeka ndi zinthu zina zamsika. Tikutumizirani mndandanda wamitengo yomwe yasinthidwa kampani yanu italumikizana nafe kuti mumve zambiri.

Ayi ndithu. tidzagwira mawu motengera kuchuluka kwanu. Mukayitanitsa zambiri, mudzapeza mtengo wabwinoko. Ndipo ngati mukufuna zitsanzo zaulere, chonde titumizireni imelo.

Inde, inde. Tikhoza kukupatsani zikalata zokhudzana, monga Zikalata Analysis / Conformance; Inshuwaransi; Zoyambira, ndi zolemba zina zotumiza kunja.

Malingana ndi kuchuluka kwanu ndi chitsanzo chanu mwatsatanetsatane, tidzakupatsani nthawi yoyenera yotsogolera. Monga mwachizolowezi, pazitsanzo, nthawi yotsogolera ndi pafupifupi masiku 7. Pakupanga misa, nthawi yotsogolera ndi masiku 20-30 mutalandira malipiro a deposit. Ufulu waulere tidziwitseni ngati muli ndi zofunikira zapadera.

Timatsimikizira zida zathu ndi kapangidwe kake. Kudzipereka kwathu ndikukhutira kwanu ndi zinthu zathu. Mu chitsimikiziro kapena ayi, ndi chikhalidwe cha kampani yathu kuthana ndi kuthetsa mavuto onse a kasitomala kuti aliyense akwaniritse

Inde, nthawi zonse timagwiritsa ntchito ma CD apamwamba kwambiri. Timagwiritsanso ntchito kulongedza kwapadera kwa zinthu zoopsa komanso zosungirako zoziziritsa zovomerezeka za zinthu zomwe zimakhudzidwa ndi kutentha. Katswiri wazolongedza ndi zofunika kulongedza zomwe sizili mulingo zitha kubweretsa ndalama zina.

Mtengo wotumizira umadalira momwe mumasankhira katunduyo. Express ndiye njira yachangu komanso yodula kwambiri. Ndi seafreight ndiye njira yabwino yothetsera ndalama zambiri. Ndendende mitengo ya katundu titha kukupatsani ngati tidziwa zambiri za kuchuluka, kulemera kwake ndi njira. Chonde titumizireni kuti mudziwe zambiri.

M'malo mwake, kusiyana pakati pa OM3 vs OM4 fiber ndikungopanga chingwe cha fiber Optical. Kusiyanaku kumatanthawuza kuti chingwe cha OM4 chimakhala chochepetsera bwino ndipo chimatha kugwira ntchito pama bandwidth apamwamba kuposa OM3. Nchifukwa chiyani izi? Kuti ulalo wa ulusi ugwire ntchito, kuwala kochokera ku VCSEL transceiver kumakhala ndi mphamvu zokwanira kufikira wolandila kumapeto kwina. Pali zikhalidwe ziwiri zogwirira ntchito zomwe zingalepheretse izi - kuwala kwa kuwala ndi kufalikira kwa modal.

Attenuation ndikuchepetsa mphamvu ya siginecha yowunikira pamene ikufalitsidwa (dB). Attenuation imayamba chifukwa cha kutayika kwa kuwala kudzera m'zigawo zongokhala, monga zingwe, zolumikizira chingwe, ndi zolumikizira. Monga tafotokozera pamwambapa zolumikizira ndizofanana kotero kusiyana kwa magwiridwe antchito mu OM3 vs OM4 kuli pakutayika (dB) mu chingwe. OM4 CHIKWANGWANI chimayambitsa kutayika kochepa chifukwa cha kapangidwe kake. Kuchepetsa kwakukulu komwe kumaloledwa ndi miyezo ikuwonetsedwa pansipa. Mutha kuwona kuti kugwiritsa ntchito OM4 kumakupatsani zotayika zochepa pa mita ya chingwe. Kutayika kwapansi kumatanthauza kuti mutha kukhala ndi maulalo ataliatali kapena kukhala ndi zolumikizira zolumikizana zambiri mu ulalo.

Kuchepetsa kwakukulu komwe kumaloledwa pa 850nm: OM3<3.5 dB/Km; OM4<3.0 dB/Km

Kuwala kumafalikira mosiyanasiyana motsatira ulusi. Chifukwa cha kuperewera kwa ulusi, mitundu iyi imafika nthawi zosiyana pang'ono. Kusiyana kumeneku kukukulirakulira, pamapeto pake mumafika pomwe zomwe zikufalitsidwa sizingadziwike. Kusiyana kumeneku pakati pa mitundu yapamwamba kwambiri ndi yotsika kwambiri kumatchedwa modal dispersion. Kubalalika kwa modal kumatsimikizira bandwidth ya modal yomwe fiber imatha kugwira ntchito ndipo uku ndiko kusiyana pakati pa OM3 ndi OM4. Kutsika kwa kufalikira kwa ma modal, kumapangitsa kuti bandwidth ya modal komanso kuchuluka kwa chidziwitso chomwe chingapatsidwe. Ma modal bandwidth a OM3 ndi OM4 akuwonetsedwa pansipa. Ma bandwidth apamwamba omwe amapezeka mu OM4 amatanthauza kubalalitsidwa kwakung'ono kwa modal ndipo motero amalola maulalo a chingwe kukhala otalikirapo kapena amalola kutayika kwakukulu kudzera pa zolumikizira zambiri. Izi zimapereka zosankha zambiri mukamayang'ana kapangidwe ka netiweki.

Bandwidth ya Chingwe Chochepa cha Fiber pa 850nm: OM3 2000 MHz·km; OM4 4700 MHz · Km

Mutha kutidziwitsa mwachangu za momwe chilengedwe chidzagwiritsire ntchito, ndikukonda zatsatanetsatane monga chinyezi, kutentha, ndi geological factor. Titha kukupatsirani zida zophatikizika za chingwe / ulusi ndi mitengo kuti zikwaniritse zomwe mukufuna. Zosankha zopangidwa mwamakonda ziliponso.
