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 elihlanganisiwe lemishini ye-PON ukuze abakhiqizi bemishini nabaqhubi bakwazi ukungena I-PON eq...

Ngokuthuthukiswa kwamadolobha esimanje maqondana nemisebenzi eminingi, ukwakheka kwedolobha kuya ngokuya kuba nzima, 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 bokuguquguquka kwesiteshi, isiteshi se-multi-fiber kanye ne-wave. Okuningi kancane...

1.Isakhiwo esiyisisekelo se-PON PON (Inethiwekhi ye-Passive Optical) i-PON iyinethiwekhi 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 yemojuli ye-optical ejova amandla amanje kumpahla ye-semiconductor futhi ikhiphe ukukhanya kwe-laser ngokusebenzisa ama-photon oscillations kanye nokuzuzwa emgodini. Njengamanje, amalaser asetshenziswa kakhulu ama-laser e-FP kanye ne-DFB. Umehluko wukuthi i-semi...

Umqondo oyisisekelo wokuxhumana kwe-fiber optical. I-fiber optical iyi-waveguide ye-dielectric optical, isakhiwo se-waveguide esivimba ukukhanya futhi sisakaze ukukhanya ku-axial direction. I-fiber enhle kakhulu eyenziwe ngengilazi ye-quartz, i-synthetic resin, njll. I-fiber yemodi eyodwa: i-core 8-10um, i-cladding 125um Multimo...
