Embonini yokuxhumana optical, amamojula optical yiwona adalulwe kakhulu.Zinobukhulu obuhlukahlukene bomzimba, futhi inani lamashaneli namazinga okudlulisela ahluka kakhulu.Lawa mamojula akhiqizwa kanjani, yiziphi izici zawo, futhi zonke izimfihlo zisezingeni.Iphakheji endala...

Ukwethulwa kwezinhlelo ezihlukahlukene ze-PON 1. Ubuchwepheshe be-APON Maphakathi nawo-1990, abanye opharetha benethiwekhi abakhulu basungula i-Full Service Access Network Alliance (FSAN), inhloso yayo kuwukwenza izinga elihlangene lemishini ye-PON ukuze abakhiqizi bemishini kanye nabaqhubi bakwazi ukungena I-PON eq...

Ngokuthuthukiswa kwamadolobha esimanje ekufezeni imisebenzi eminingi, ukwakheka kwedolobha kuya ngokuya kuba yinkimbinkimbi, futhi kukhona amakhulu, amakhulu, noma izinkulungwane zamaphoyinti okuqapha aphansi.Ukuqinisekisa ukuthi iminyango esebenzayo iyakwazi ukubamba isithombe sevidiyo sesikhathi sangempela, esicacile nesisezingeni eliphezulu...

Ukuhola: I-100G Ethernet kusuka ocwaningweni kuya kwezohwebo, idinga ukuxazulula ubuchwepheshe obubalulekile bokuxhumana, ukupakisha, ukudlulisa, izingxenye ezibalulekile, njll. Ubuchwepheshe obuyinhloko be-interface ye-100G Ethernet yamanje buhlanganisa ungqimba olubonakalayo, ubuchwepheshe bokuguqulwa kwesiteshi, isiteshi se-multi-fiber kanye ne-wave. Okuningi kancane...

1.Isakhiwo esiyisisekelo se-PON PON (Inethiwekhi ye-Passive Optical) i-PON inethiwekhi yokufinyelela ye-fiber eyodwa ye-bidirectional optical esebenzisa isakhiwo se-point-to-multipoint (P2MP).Uhlelo lwe-PON lwakhiwe i-optical line terminal (OLT), i-optical distribution network (ODN), kanye ne-optical network unit (ONU) on...

1.Isigaba se-laser I-laser iyingxenye emaphakathi kakhulu yemojula ye-optical ejova i-manje ku-semiconductor impahla futhi ikhiphe ukukhanya kwe-laser ngokusebenzisa ama-photon oscillations kanye nenzuzo emgodini.Njengamanje, amalaser asetshenziswa kakhulu ama-laser e-FP kanye ne-DFB.Umehluko wukuthi i-semi...
