2.1.Zofunikira pa njira yotumizira mauthenga:
2.1.1. Kutumiza mautumiki a 14*10 Gigabit kuchokera ku chipinda cha makompyuta cha mzinda kupita ku chipinda cha makompyuta cha Nanhai
2.1.2, ntchito yaikulu ya njira, chosinthira njira yosungira≤32mm
2.1.3. OTU yapafupi ingagwiritsidwe ntchito kupanga chizindikiro, kukulitsa, ndikutulutsa wotchi.
2.2. Zofunikira pa njira yotumizira mauthenga:
2.2.1. Kutumiza mautumiki a 14*10 Gigabit kuchokera ku chipinda cha makompyuta cha mzinda kupita ku chipinda cha makompyuta cha Shunde
2.2.2, ntchito yaikulu ya njira, chosinthira njira yosungira ≤ 32mms
2.3.3. OTU yapafupi ingagwiritsidwe ntchito kupanga chizindikiro, kukulitsa, ndikutulutsa wotchi.
2.3. Zofunikira pa njira yotumizira mauthenga:
2.3.1. Mautumiki a 8*10 Gigabit amatumizidwa kuchokera ku chipinda cha makompyuta cha mzinda kupita ku chipinda cha makompyuta cha Gaoming
2.3.2. Njira yaikulu imagwira ntchito ndipo chosinthira njira ina ndi ≤32mms
2.3.3. OTU yapafupi ingagwiritsidwe ntchito kupanga chizindikiro, kukulitsa, ndikutulutsa wotchi.
3.1. Kufotokozera pulogalamu
3.1.1. Poganizira za kukula kwa mphamvu, chipangizo chochotsera mafunde ambiri chimapangidwa molingana ndi mafunde 8
3.1.2. Kuwerengera deta yoperekedwa kuti chingwe cha kuwala chichepetse (kutayika kwa kulumikizana ndi kutayika kwa cholowera zikuphatikizidwa).
3.1.3. Kuwerengera mphamvu ya kuwala kwa ulalo:
Mphamvu yowunikira ya single-wave ya optical module imawerengedwa pa 0dBm (-2 ~ 3dBm), yowonjezeredwa ndi BA ndikuchepetsedwa ndi OLP, mphamvu yowunikira ya fiber yomwe ikubwera ndi +4dBm, yochepetsedwa ndi mzere wa 27dBm, OLP 2dB yochepetsedwa, ndipo mphamvu yolowa mu PA ndi -25dBm, Pambuyo pa PA 20dB amplification, mphamvu ya single-wave ndi -5dBm, pambuyo pa DEMUX de-wave, mphamvu ya single-wave ndi -10dBm, yomwe ikutsimikizika kuti ili mkati mwa sensitivity range ya optical module;
Kubwerera m'mbuyo: Pambuyo powerengera, mphamvu ya mafunde amodzi kumapeto kolandira ndi -10dBm, zomwe zikutsimikiziridwa kuti zili mkati mwa kuchuluka kwa mphamvu ya gawo la optical.
3.1.4. Kuwerengera kwa OSNR ya System (kosavuta): OSNR=58+4-27-1-6=28dB≥24dB, komwe kumakwaniritsa zofunikira pa kapangidwe kake.
3.2. Ubwino wa yankho
3.2.1. Gwiritsani ntchito DWDM kuchulukitsa mautumiki 40 pa chingwe chimodzi chowunikira kuti mutumize mauthenga, zomwe zimapulumutsa kwambiri chuma cha chingwe chowunikira pamene mukutsimikizira bandwidth;
3.2.2. Kukhazikika kwakukulu: Kapangidwe ka njira iyi kamagwiritsa ntchito chitetezo cha njira ziwiri za OLP 1+1, kumathandizira kusinthana kokha, ndikutsimikizira kukhazikika kwa bizinesi;
3.2.3. Zipangizo za WDM zimagwiritsa ntchito kapangidwe ka modular, zimalekanitsa zogwira ntchito ndi zosagwira ntchito, zosavuta kukulitsa, zimangofunika kuwonjezera bolodi lothandizira likakula, popanda kusokoneza bizinesi yomwe ilipo.
3.2.4. Bodi ya OTU imagwiritsa ntchito kapangidwe ka 3R, komwe kangathe kusintha mawonekedwe a chizindikiro, kukulitsa wotchi ndikusintha nthawi kuti zitsimikizire kuti chizindikirocho sichinasinthe.
3.2.5. Thandizani mautumiki osiyanasiyana kuti mupeze SDH, PDH, CATV, Ethernet, deta ya mawu, ndi zina zotero, zogwirizana ndi zida zochokera kwa opanga osiyanasiyana
3.2.6. Chipangizochi chimapereka mphamvu yosungiramo zinthu zotentha ya 1+1, zomwe zimapangitsa kuti chipangizocho chikhale chokhazikika
3.2.7. Ali ndi ntchito zamphamvu zoyang'anira maukonde, zomwe zimatha kuyendetsa maukonde akutali, kuyang'anira bizinesi pa intaneti nthawi yeniyeni, komanso kuthandizira kukonza.
