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...

Umsebenzi oyinhloko wesixhumi se-fiber optic ukuxhuma ngokushesha imicu emibili ukuze isignali ye-optical iqhubeke nokwenza indlela ye-optical. Izixhumi ze-Fiber optic zihamba, ziyakwazi ukusebenziseka kabusha, futhi ziyizingxenye ze-passive ezibaluleke kakhulu nezisetshenziswa kakhulu ezinhlelweni zokuxhumana ezibonakalayo.

Imojula ye-optical iyingxenye ye-electronic photoelectrically converted. Ukukhuluma nje, isignali ye-optical iguqulwa ibe isignali kagesi, futhi isignali kagesi iguqulelwe ibe isignali yokubona, ehlanganisa idivayisi yokudlulisa, idivayisi eyamukelayo, nokusebenza kukagesi...
