2.1.Umuyoboro w'itumanaho usabwa:
2.1.1.Kohereza serivisi za 14 * 10 Gigabit kuva mucyumba cya mudasobwa yo mu mujyi kugeza mucyumba cya mudasobwa cya Nanhai
2.1.2, inzira nyamukuru ikora, inzira yo gusubira inyuma≤32mms
2.1.3.OTU yaho irashobora gukoreshwa mugushiraho ibimenyetso, kwagura, no gukuramo isaha.
2.2.Umuyoboro w'itumanaho usabwa:
2.2.1.Kohereza serivisi za 14 * 10 Gigabit kuva mucyumba cya mudasobwa yo mumujyi kugera mucyumba cya mudasobwa ya Shunde
2.2.2, inzira nyamukuru ikora, inzira yo gusubira inyuma inzira ≤ 32mms
2.3.3.OTU yaho irashobora gukoreshwa mugushiraho ibimenyetso, kwagura, no gukuramo isaha.
2.3.Umuyoboro w'itumanaho usabwa:
2.3.1.8 * 10 Serivise za Gigabit zoherejwe kuva mucyumba cya mudasobwa cyo mu mujyi kugera mu cyumba cya mudasobwa cya Gaoming
2.3.2.Inzira nyamukuru ikora kandi inzira ihinduranya ni ≤32mms
2.3.3.OTU yaho irashobora gukoreshwa mugushiraho ibimenyetso, kwagura, no gukuramo isaha.
3.1.Ibisobanuro bya porogaramu
3.1.1.Urebye kwaguka kwubushobozi, igice cya demultiplexing cyakozwe ukurikije imiraba 8
3.1.2.Kubara amakuru yatanzwe kugirango yongere umugozi wa optique (igihombo cyo guhuza no gutakaza insimburangingo zirimo).
3.1.3.Ihuza imbaraga za optique zo kubara:
Icyerekezo kimwe: Imbaraga imwe yumucyo wumucyo wa module optique ibarwa kuri 0dBm (-2 ～ 3dBm), ikongerwaho na BA kandi igahuzwa na OLP, fibre optique yinjira ni + 4dBm, ihujwe numurongo 27dBm, OLP 2dB yegeranye, n'imbaraga zinjira muri PA ni -25dBm, Nyuma yo kongera PA 20dB, imbaraga imwe -5dBm, nyuma ya DEMUX de-wave, imbaraga imwe-imwe ni -10dBm, byemezwa ko izaba iri murwego rwo kwiyumvamo module;
Inyuma: Nyuma yo kubara, imbaraga imwe-yumurongo kumpera yakira ni -10dBm, byemezwa ko izaba iri murwego rwo kwiyumvamo ibintu bya optique
3.1.4.Sisitemu OSNR kubara (byoroshye): OSNR = 58 + 4-27-1-6 = 28dB≥24dB, yujuje ibyashizweho.
3.2.Ibyiza byo gukemura
3.2.1.Koresha DWDM kugirango ugwize serivisi 40 kumurongo umwe wa optique kugirango wohereze, uzigama cyane ibikoresho bya optique mugihe wizeye neza;
3.2.2.Ihungabana rikomeye: Iki gishushanyo mbonera cyakiriye OLP 1 + 1 kurinda inzira ebyiri, ishyigikira guhinduranya byikora, kandi ikemeza ko ubucuruzi butajegajega;
3.2.3.Ibikoresho bya WDM bifata igishushanyo mbonera, gutandukanya gukora na pasiporo, byoroshye kwaguka, gusa ukeneye kongera inama ya serivisi mugihe wagutse, bitabangamiye ubucuruzi buriho
3.2.4.Ubuyobozi bwa OTU bwakiriye igishushanyo cya 3R, gishobora guhindura ibimenyetso, kongerera isaha no kongera kugihe kugirango ibimenyetso bitagoreka
3.2.5.Shyigikira serivisi zitandukanye kugirango ugere kuri SDH, PDH, CATV, Ethernet, amakuru yijwi, nibindi, bihujwe nibikoresho biva mubakora bitandukanye
3.2.6.Igikoresho gitanga amashanyarazi ashyushye 1 + 1, atezimbere igikoresho
3.2.7.Gutunga imikorere ikomeye yo gucunga imiyoboro, ishobora kumenya imiyoborere ya kure, kumenya kumurongo mugihe gikurikirana ibikorwa, no koroshya kubungabunga
