2.3. Shuruudaha kanaalka gudbinta:
2.3.1. Adeegyada 8*10 Gigabit waxaa laga soo gudbiyaa qolka kombiyuutarka magaalada ilaa qolka kombiyuutarka Gaoming.
2.3.2. Wadada ugu weyn way shaqaysaa, badhanka wadada ee kale waa ≤32mms
2.3.3. OTU-ga maxalliga ah waxaa loo isticmaali karaa in lagu qaabeeyo calaamadda, lagu ballaariyo, laguna soo saaro saacadda.
3.1. Sharaxaadda Barnaamijka
3.1.1. Marka la eego ballaarinta awoodda, cutubka kala-baxa hirarka waxaa loogu talagalay 8 hirar.
3.1.2. Xisaabinta xogta la bixiyay ee lagu yareynayo fiilada indhaha (lumitaanka isku xirka iyo luminta gelinta ayaa ku jira).
3.1.3. Xisaabinta awoodda indhaha ee isku xirka:
Hal jiho: Awoodda iftiinka hal-hir ee module-ka indhaha waxaa lagu xisaabiyaa 0dBm (-2~3dBm), oo lagu xoojiyay BA oo lagu khafiifiyay OLP, awoodda iftiinka ee fiber-ka soo socota waa +4dBm, oo lagu khafiifiyay xariiqda 27dBm, OLP 2dB oo la yareeyay, awoodda soo galaysa PA-na waa -25dBm., Ka dib kordhinta PA 20dB, awoodda hal-hir waa -5dBm, ka dib de-mowjadda DEMUX, awoodda hal-hir waa -10dBm, taas oo la hubo inay ku jirto xadka xasaasiga ah ee module-ka indhaha;
Dib-u-eegis: Ka dib xisaabinta, awoodda hal-hir ee dhamaadka helitaanka waa -10dBm, taas oo la hubo inay ku jirto xadka xasaasiga ah ee module-ka indhaha
3.1.4. Xisaabinta nidaamka OSNR (fudud): OSNR=58+4-27-1-6=28dB≥24dB, kaas oo buuxiya shuruudaha naqshadeynta.
3.2. Faa'iidooyinka xalka
3.2.1. Adeegso DWDM si aad u isticmaasho adeegyo badan oo 40 ah hal fiilo oo indhaha ah si aad u gudbiso, taasoo si weyn u badbaadinaysa ilaha fiilada indhaha iyadoo la hubinayo baaxadda;
3.2.2. Xasillooni sare: Naqshadeynta xalkan waxay qaadataa ilaalinta laba-geesoodka ah ee OLP 1+1, waxay taageertaa beddelka otomaatiga ah, waxayna hubisaa xasilloonida ganacsiga;
3.2.3. Qalabka WDM wuxuu qaataa naqshad moodeel ah, firfircoon oo kala gooni ah, si fudud loo ballaarin karo, kaliya waxay u baahan tahay in la kordhiyo guddiga adeegga marka la ballaarinayo, iyada oo aan la carqaladeyn ganacsiga jira.
3.2.4. Guddiga OTU wuxuu qaataa naqshad 3R ah, kaas oo dib u qaabeyn kara calaamadda, ballaarin kara saacadda iyo dib u habaynta waqtiga si loo hubiyo in calaamaddu aysan qalloocanayn.
3.2.5. Taageer adeegyo kala duwan si aad u hesho SDH, PDH, CATV, Ethernet, xogta codka, iwm., oo la jaan qaadaya qalabka ka imanaya soosaarayaal kala duwan.
3.2.6. Qalabku wuxuu bixiyaa koronto kayd ah oo 1+1 ah, taasoo hagaajinaysa xasilloonida qalabka.
3.2.7. Leh hawlo maamul shabakadeed oo awood leh, kuwaas oo xaqiijin kara maaraynta shabakadaha fog, xaqiijin kara la socodka ganacsiga waqtiga-dhabta ah ee khadka tooska ah, iyo fududeyn kara dayactirka.
