2.1.2, akazi k'inzira nyamukuru, uburyo bwo gusimbuza inzira≤mm 32
2.1.3. OTU yo mu gace irashobora gukoreshwa mu gushushanya ikimenyetso, kongera imbaraga no gukuramo isaha.
2.2. Ibisabwa ku muyoboro w’itumanaho:
2.2.1. Kohereza serivisi za 14*10 Gigabit kuva mu cyumba cya mudasobwa cyo mu mujyi kugera mu cyumba cya mudasobwa cya Shunde
2.2.2, akazi k'inzira nyamukuru, switch y'inzira y'inyongera ≤ 32mms
2.3.3. OTU yo mu gace irashobora gukoreshwa mu gushushanya ikimenyetso, kongera imbaraga no gukuramo isaha.
2.3. Ibisabwa ku muyoboro w’itumanaho:
2.3.1. Serivisi za Gigabit 8*10 zoherezwa mu cyumba cya mudasobwa cyo mu mujyi zijya mu cyumba cya mudasobwa cya Gaoming
2.3.2. Inzira nyamukuru irakora kandi inzira isimburana ni ≤32mm
2.3.3. OTU yo mu gace irashobora gukoreshwa mu gushushanya ikimenyetso, kongera imbaraga no gukuramo isaha.
3.1. Ibisobanuro bya gahunda
3.1.1. Ukurikije kwagura ubushobozi, igice cyo gukuramo ibintu byinshi mu miraba cyakozwe hakurikijwe imiraba 8
3.1.2. Kubara amakuru yatanzwe kugira ngo insinga y'amashanyarazi igabanuke (harimo gutakaza umurongo w'itumanaho no gutakaza insertion).
3.1.3. Kubara ingufu z'urukiramende:
Ibyerekezo bito: Ingufu z'urumuri rw'umuraba umwe zibarwa kuri 0dBm (-2 ~ 3dBm), zongerwamo BA kandi zigagabanukamo OLP, imbaraga z'urumuri rw'umuraba winjira ni +4dBm, zigabanukamo umurongo wa 27dBm, OLP 2dB igabanutsemo, kandi imbaraga zinjira muri PA ni -25dBm, Nyuma yo kongeramo PA 20dB, imbaraga z'umuraba umwe ni -5dBm, nyuma yo gukuramo umuraba wa DEMUX, imbaraga z'umuraba umwe ni -10dBm, byemewe ko ziri mu rugero rw'ubushobozi bwo gupima imiterere y'umuraba w'umuraba;
Isubira inyuma: Nyuma yo kubara, imbaraga z'umuraba umwe ku mpera yo kwakira ni -10dBm, byemejwe ko biri mu rugero rwo gupima imiterere y'urumuri rw'amashanyarazi.
3.1.4. Ibarura rya sisitemu ya OSNR (ryoroshye): OSNR=58+4-27-1-6=28dB≥24dB, ihuye n'ibipimo by'igishushanyo.
3.2. Ibyiza by'ibisubizo
3.2.1. Koresha DWDM kugira ngo ukoreshe serivisi 40 kuri insinga imwe y'ikoranabuhanga kugira ngo wohereze ubutumwa, ibyo bikaba bizigama cyane umutungo w'insinga y'ikoranabuhanga mu gihe bigenzura ko bandwidth igenda;
3.2.2. Gutuza cyane: Iyi gahunda y'igisubizo ikoresha uburyo bwa OLP 1+1 bwo kurinda inzira ebyiri, ishyigikira guhinduranya ibintu mu buryo bwikora, kandi ikanatuma ubucuruzi butuza;
3.2.3. Ibikoresho bya WDM bikoresha imiterere ya modular, bitandukanye active na passive, byoroshye kwagura, bisaba kongera gusa serivisi iyo byaguka, nta guhungabanya ubucuruzi busanzweho.
3.2.4. Inama y'ubuyobozi ya OTU ikoresha igishushanyo cya 3R, gishobora guhindura ishusho y'ikimenyetso, kongera isaha no kongera igihe kugira ngo ikimenyetso kidahinduka
3.2.5. Gushyigikira serivisi zitandukanye kugira ngo ubone SDH, PDH, CATV, Ethernet, amakuru y'ijwi, nibindi, bihuye n'ibikoresho biva mu nganda zitandukanye
3.2.6. Igikoresho gitanga amashanyarazi ashyushye ya 1+1, ibyo bigatuma igikoresho gihora gihagaze neza
3.2.7. Kugira imirimo ikomeye yo gucunga umuyoboro w'itumanaho, ishobora gukora imicungire y'umuyoboro uri kure, gukora igenzura ry'ubucuruzi kuri interineti mu gihe nyacyo, no koroshya kubungabunga
