3.1.Kufotokozera pulogalamu
3.1.1.Poganizira kukula kwa mphamvu, gawo la wave demultiplexing limapangidwa molingana ndi mafunde 8
3.1.2.Kuwerengera zomwe zaperekedwa pakuchepetsa chingwe cha kuwala (kutayika kwa kulumikizana ndi kutayika kwa kuyika zikuphatikizidwa).
3.1.3.Lumikizani mawerengedwe a mphamvu ya kuwala:
Unidirectional: Mphamvu yowala yowoneka bwino ya mawonekedwe amodzi amawerengedwa pa 0dBm (-2 ~ 3dBm), yokulitsidwa ndi BA ndikuchepetsedwa ndi OLP, mphamvu yobwera ya fiber ndi +4dBm, yochepetsedwa ndi mzere 27dBm, OLP 2dB yochepetsedwa, ndipo mphamvu yolowa mu PA ndi -25dBm , Pambuyo pa kukulitsa kwa PA 20dB, mphamvu yamafunde amodzi ndi -5dBm, pambuyo pa DEMUX de-wave, mphamvu yamafunde amodzi ndi -10dBm, yomwe imatsimikiziridwa kuti ili mkati mwazomvera za Optical module;
Kubwereranso: Pambuyo powerengera, mphamvu yamafunde amodzi pamapeto olandila ndi -10dBm, yomwe imatsimikizika kuti ili mkati mwa gawo la sensor ya optical.
3.1.4.Kuwerengera kwa OSNR kwadongosolo (kosavuta): OSNR=58+4-27-1-6=28dB≥24dB, yomwe imagwirizana ndi mapangidwe ake.
3.2.Yankho ubwino
3.2.1.Gwiritsani ntchito DWDM kuti muwonjezere mautumiki a 40 pa chingwe chimodzi chowunikira kuti mutumize, chomwe chimapulumutsa kwambiri zipangizo zamagetsi pamene mukuonetsetsa kuti bandwidth;
3.2.2.Kukhazikika kwakukulu: Kukonzekera kwa njira iyi kumatengera chitetezo cha njira ziwiri za OLP 1 + 1, kumathandizira kusintha kwachangu, ndikuwonetsetsa kukhazikika kwabizinesi;
3.2.3.Zida za WDM zimatengera kapangidwe kake, kupatukana kogwira ntchito komanso kungokhala chete, kosavuta kukulitsa, kumangofunika kuwonjezera gulu lautumiki pokulitsa, popanda kusokoneza bizinesi yomwe ilipo.
3.2.4.Bungwe la OTU limagwiritsa ntchito mapangidwe a 3R, omwe amatha kukonzanso chizindikiro, kukulitsa wotchi ndikukonzanso nthawi kuti zitsimikizire kuti chizindikirocho sichinasokonezedwe.
3.2.5.Thandizani mautumiki osiyanasiyana kuti mupeze SDH, PDH, CATV, Efaneti, deta yamawu, ndi zina zotero, zogwirizana ndi zipangizo zochokera kwa opanga osiyanasiyana.
3.2.6.Chipangizochi chimapereka mphamvu zosungirako zotentha za 1 + 1, zomwe zimathandizira kukhazikika kwa chipangizocho
3.2.7.Khalani ndi magwiridwe antchito amphamvu amanetiweki, omwe amatha kuzindikira kasamalidwe ka netiweki akutali, kuzindikira kuwunika kwapaintaneti munthawi yeniyeni, ndikuwongolera kukonza
