OTN na PTN
Bikwiye kuvugwa ko OTN na PTN ari tekinoloji ebyiri zitandukanye rwose, kandi muburyo bwa tekiniki, hakwiye kuvugwa ko ntaho bihuriye.
OTN ni umuyoboro mwiza wo gutwara abantu, uva mu buhanga gakondo bwo kugabana umurongo.Yongeyeho cyane cyane ubwenge bwa optique yo guhinduranya imikorere.Irashobora gutahura optique yambukiranya iboneza ryamakuru idafite intoki zisimbuka.Kubungabunga no guhuza ibikoresho bya WDM byateye imbere cyane.Muri icyo gihe, urusobe rushya rwa OTN rugenda rwiyongera buhoro buhoro kugera ku ntera nini, ibice binini, no kurinda bikomeye.

PTN numuyoboro wogutwara paki, nigicuruzwa cyo guhuza imiyoboro itwara abantu hamwe numuyoboro wamakuru.Porotokole nyamukuru ni TMPLS, ifite IP nkeya hamwe nudupaki twinshi kuruta ibikoresho byurusobe.Irashobora kumenya guhuza impeta no kurinda.Numuyoboro wabatwara-urwego rwamakuru (imiyoboro yamakuru gakondo ntishobora kuzuza ibisabwa byabatwara-ibyiciro).Umuyoboro mugari wa PTN ni muto ugereranije na OTN.Mubisanzwe, umurongo ntarengwa witsinda rya PTN ni 10G, OTN umurongo umwe ni 10G, inzira yitsinda irashobora kugera kuri 400G-1600G, kandi ikoranabuhanga rigezweho rishobora kugera kumurongo umwe 40G.Ninkingi yumurongo wohereza.

OTN na SDH, WDM

OTN ishingiye ku ikoranabuhanga rya WDM, imikorere ikomeye, kubungabunga, gucunga no kugabura (OAM) ubushobozi bwa SDH butangizwa hashingiwe ku bushobozi bunini bwo kohereza.OTN ikoresha FEC yashyizwemo, ikungahaye cyane mu kubungabunga no gucunga neza, kandi irakwiriye kuri serivisi nini-nini yo kubona serivisi ya FEC ikosora amakosa, ikosora imikorere ya bito kandi ikongera igihe cyo kohereza optique.

Porogaramu ya OTN

Umuyoboro wa optique ushingiye kuri OTN uzatanga igisubizo cyiza cyo kohereza serivise nini-nini ya serivise.Umuyoboro wo gutwara abantu ugizwe ahanini n’urusobe rw’ubwikorezi hagati y’intara, umuyoboro w’ubwikorezi hagati y’intara, hamwe n’umuyoboro wa metro (waho).Umuyoboro wa transport wa metro (waho) urashobora kugabanywa mubice byingenzi, igiteranyo cyo guteranya hamwe no kugera.Ugereranije na SDH, inyungu nini ya tekinoroji ya OTN ni ugutanga gahunda no kohereza imiyoboro minini ya granularity.Kubwibyo, niba wakoresha tekinoroji ya OTN kumurongo itandukanye biterwa nubunini bwa gahunda nyamukuru ya gahunda ya bande ya granularity.Ukurikije uko ibintu byifashe muri iki gihe, ibice byingenzi bigize gahunda yibanze ya gahunda yo gukwirakwiza imiyoboro ihuza intara hagati y’intara, umuyoboro w’itumanaho hagati y’intara hamwe n’umuyoboro wa metero (waho) muri rusange ni Gb / s no hejuru.Tekinoroji nziza ya OTN kubaka.
Kubijyanye no kwegeranya no kugera kurwego rwumujyi wa metropolitani (local) umuyoboro wogutwara, mugihe ibice byingenzi byateganijwe bigera kurwego rwa Gb / s, tekinoroji ya OTN nayo irashobora kubakwa.

1. Umuyoboro wogutwara optique wigihugu hamwe numuyoboro wa IP na serivisi bishingiye kuri IP, iterambere rya serivisi nshya no kwiyongera byihuse kubakoresha umurongo mugari, traffic IP kumurongo wigihugu yiyongereye cyane, kandi umurongo mugari wiyongereye cyane uko umwaka utashye .Umurongo wa WDM wigihugu utwara PSTN / 2G serivisi ndende, serivise ndende za NGN / 3G, hamwe na serivise yigihugu ya enterineti.Bitewe numubare munini wa serivise zitwara abantu, imirongo yigihugu ya WDM ikeneye byihutirwa kurinda serivisi zabatwara.Nyuma yo gukoresha tekinoroji ya OTN, uburyo bwitwara bwumurongo wigihugu IP hejuru ya OTN burashobora kubona uburinzi bwa SNCP, kurinda imiyoboro ya SDH imeze, kurinda imiyoboro ya MESH nubundi buryo bwo kurinda imiyoboro.Yagabanutse cyane.

2. Umuyoboro wogutwara intara hagati yintara / uturere Uturere two hagati yintara / uturere twomugongo utwara serivisi hagati y'ibiro birebire (NGN / 3G / IPTV / umurongo wihariye kubakiriya bakomeye, nibindi).Binyuze mu iyubakwa ry’intara / uturere OTN imiyoboro yohereza imiyoboro ya optique, itumanaho ryizewe kandi ryizewe rya GE / 10GE, 2.5G / 10GPOS serivisi nini nini irashobora kugerwaho;imiyoboro y'impeta, imiyoboro igoye, hamwe na MESH imiyoboro irashobora gushirwaho;umuyoboro urashobora kwagurwa kubisabwa;Menya guhuza gahunda no gutunganya serivisi z'umurambararo / munsi-ya-munsi ya serivisi, kandi utange umurongo wa serivise / umurongo wa serivisi wihariye kubakiriya benshi;menya kandi kohereza izindi serivisi nka STM-1/4/16 / 64SDH, ATM, FE, DVB, HDTV, BURUNDU, nibindi.

3. Metro / imiyoboro ya transport ya optique Kumurongo wibanze wurusobe rwa metero, umuyoboro wa transport wa OTN urashobora kubona serivisi nini nini mugari hagati ya metro yoguhuza metro, umuyoboro waho C4 (uturere / intara hagati) hamwe na metero nkuru. Router.ohereza.Imigaragarire yo hejuru ya router ni GE / 10GE, kandi irashobora no kuba 2.5G / 10GPOS.Umuyoboro wa optique wo gutwara abantu kuri metero ya l
