2.1.3. I-OTU yendawo ingasetshenziswa ukubumba isignali, ukukhulisa, nokukhipha iwashi.
2.2. Izidingo zesiteshi sokudlulisa:
2.2.1. Ukudluliselwa kwezinsizakalo ze-14*10 Gigabit zisuka egumbini lamakhompyutha ledolobha ziye egumbini lamakhompyutha le-Shunde
2.2.2, umsebenzi womzila oyinhloko, inkinobho yomzila oyisipele ≤ 32mms
2.3.3. I-OTU yendawo ingasetshenziswa ukubumba isignali, ukukhulisa, nokukhipha iwashi.
2.3. Izidingo zesiteshi sokudlulisa:
2.3.1. Izinsizakalo ze-8*10 Gigabit zidluliselwa zisuka ekamelweni lamakhompyutha edolobheni ziye egumbini lamakhompyutha le-Gaoming
2.3.2. Umzila oyinhloko uyasebenza futhi iswishi yomzila ehlukile ingu-≤32mms
2.3.3. I-OTU yendawo ingasetshenziswa ukubumba isignali, ukukhulisa, nokukhipha iwashi.
3.1. Incazelo yohlelo
3.1.1. Uma kucatshangelwa ukwanda komthamo, iyunithi yokususa amaza amaningi yakhelwe ngokwamaza ayi-8
3.1.2. Ukubalwa kwedatha enikeziwe yokunciphisa ikhebula le-optical (ukulahlekelwa kokuxhumeka kanye nokulahlekelwa kokufakwa kufakiwe).
3.1.3. Ukubalwa kwamandla okukhanya kwesixhumanisi:
Unidirectional: Amandla okukhanya kwe-single-wave yemodule ye-optical abalwa ku-0dBm (-2 ～3dBm), akhuliswe yi-BA futhi ancishiswe yi-OLP, amandla okukhanya kwe-fiber engenayo ayi-+4dBm, ancishiswe yi-line 27dBm, i-OLP 2dB incishisiwe, kanti amandla angena ku-PA ayi--25dBm, Ngemva kokukhulisa kwe-PA 20dB, amandla e-single-wave ayi--5dBm, ngemva kokususa i-DEMUX, amandla e-single-wave ayi--10dBm, okuqinisekisiwe ukuthi angaphakathi kobubanzi bokuzwela bemodule ye-optical;
Ukuhlanekezela: Ngemva kokubala, amandla e-single-wave ekugcineni kokwamukela angu--10dBm, okuqinisekisiwe ukuthi angaphakathi kobubanzi bokuzwela be-optical module
3.1.4. Ukubalwa kwesistimu ye-OSNR (elula): i-OSNR=58+4-27-1-6=28dB≥24dB, ehlangabezana nezimfuneko zomklamo.
3.2. Izinzuzo zesisombululo
3.2.1. Sebenzisa i-DWDM ukuze uhlanganise amasevisi angu-40 kukhebula elilodwa le-optical ukuze udlulisele, okusindisa kakhulu izinsiza zekhebula le-optical ngenkathi kuqinisekiswa i-bandwidth;
3.2.2. Ukuqina okuphezulu: Lo mklamo wesixazululo usebenzisa ukuvikelwa komzila ombaxambili we-OLP 1+1, usekela ukushintsha okuzenzakalelayo, futhi uqinisekisa ukuzinza kwebhizinisi;
3.2.3. Imishini ye-WDM isebenzisa ukwakheka kwe-modular, ihlukanisa esebenzayo nengasebenzi, kulula ukuyikhulisa, idinga kuphela ukwandisa ibhodi yesevisi lapho ikhula, ngaphandle kokuphazamisa ibhizinisi elikhona.
3.2.4. Ibhodi le-OTU lamukela ukwakheka kwe-3R, okungayishintsha i-signal, kukhulise iwashi futhi kuphinde kushintshwe isikhathi ukuqinisekisa ukuthi i-signal ayiphambuki.
3.2.5. Sekela izinsizakalo ezahlukene ukuze ufinyelele ku-SDH, i-PDH, i-CATV, i-Ethernet, idatha yezwi, njll., ehambisana nemishini evela kubakhiqizi abahlukene
3.2.6. Idivayisi inikeza ugesi oyisipele oshisayo ongu-1+1, okuthuthukisa ukuzinza kwedivayisi
3.2.7. Unemisebenzi enamandla yokuphatha inethiwekhi, engenza ukuphathwa kwenethiwekhi okude, ifeze ukuqapha kwebhizinisi oku-inthanethi ngesikhathi sangempela, futhi ikhuthaze ukulungiswa
