Epon (Ethernet Passive Optical Network)
Ethernet Passive Optical Network est Pon Technology Ex Aer. Hoc adoptat a puncto ad pluresint structuram et passive alimentorum fibra opticum tradenda, providente plures officia in Aer. Epon technology est de mensuris per Ieee802.3 EFM opus coetus. In June MMIV, in Ieee802.3EFM Opus Group dimisit in Epon Latin - Iee802.3ah (merged in Ieee802.3-2005 in MMV).
In hac vexillum, Ethernet et pon technologies sunt combined, cum Pon technology usus est in physica accumsan et Aer Protocollo solebat ad Data Link iacuit, utilizing in Topology de Pon ad consequi Aer aditus. Ergo combines commoda Pon technology et Aer technology: humilis sumptus, princeps Bandwidth, fortis scalability, compatibility cum existens ethet, convenient administratione, etc.
GPON (Gigabit-Capax Pon)
Et technology est tardus generationem de Broadband passiva optical integrated aditum vexillum secundum ITU, TG.984. X vexillum, quod habet multa commoda ut altus Bandwidth, princeps efficientiam, magna coverage area, et dives user interfaces. Non spectatur ab maxime operators ut specimen technology ad consequi broadband et comprehensive transformatio accessum network servicia. GPON erat primus propositus per FSAN Organization in September MMII. Ex hoc, ITU-T complebitur progressionem ITU-T G.984.1 et G.984.2 in March MMIV, et standardized G.984.3 in Februario et June MMIV.
GPON Technology Originated a Atmpon Technology Latin quod paulatim formatae in MCMXCV et pon stat pro "passiva optical network" in English. Gigabit GPON (Gigabit Passive Optical Network) Primo propositus est a FSAN organization in September MMII. Ex hoc, ITU-T complebitur progressionem ITU-T G.984.1 et G.984.2 in Martii MMIV, et standardized Februarii in Februarii et June MMIV. In basic structuram cogitationes fundatur in GPON technology est similis existentium Pon, constans ex Olt (optical linea terminatio) ad Central Official, Odn (Smatica PRINCTING) et Passivum Distribution System.
Differentia inter Epon et GPON
GPON utilitas unam divisionem multiplexing (WDM) technology ad enable simultaneous uploading et download. Usualiter, a 1490nm optical tabellarius adhibetur ad downloading, cum a 1310nm optical tabellarius est electus ad uploading. Si TV annuit postulo ut traducitur, a 1550nm optical carrier erit quoque esse. Licet quisque ONU potest consequi a download celeritas 2.488 gbits / s, GPON etiam utitur tempus division multiple accessum (TDMA) ad collocant quaedam tempus socors pro se user in periodica signum.
Maxime download rate of xgpon est ad 10Gbits / s, et upload rate est etiam 2.5Gbit / s. Etiam utitur WDM technology, et ad Wavelengths de fluminibus et Downstream optical carriers sunt 1277nm et 1577nm, respective.
Ob auctus traductionem rate, magis onus potest scinditur secundum idem notitia format, cum a maximam coverage procul ad 20km. Licet xgpon non late adoptivum tamen, quod providet bonum upgrade iter ad optical communicationis operators.
Epon est plene compatible cum aliis ethernet signa, sic non est opus ad conversionem vel encapsulation cum pertinent ad Aer secundum retiacula, cum maximum payload de MDXVIII bytes. Epon non eget CSMA / CD aditus modum in certa Ethernet versions. Insuper, ut Aer Transmissus est principalis methodo loci spatio network tradenda, ibi est opus network protocollo conversionem in upgrade ad metropolitan area network.
Est etiam a X GBIT / Ser Version 702.3AV Ser. In ipsa linea celeritas est 10,3125 gbits / s. Pelagus modus est X gbits / s uplink et downlink rate, cum quibusdam usura X gbits / s downlink et I GBIT / s uplink.
Et GBIT / S Version utitur diversis optical unda fluvelengths in fibra, cum downstream unam 1575-1580nm et flumentham de 1260-1280nm. Ideo X GBIT / S system et vexillum 1GBit / s system potest esse simul multiplexed in eodem fibra.
Triplex fabula integration
The convergence of three networks means that in the process of evolution from telecommunication network, radio and television network, and Internet to broadband communication network, digital television network, and next-generation Internet, the three networks, through technical transformation, tend to have the same technical functions, the same business scope, network interconnection, resource sharing, and can provide users with voice, data, radio and television and other services. Triplex merger non intelliguntur corporis integrationem trium major retiacula, sed maxime refertur ad fusionem summus gradu negotium applications.
Integration trium networks est late in variis campis ut intelligentes translationem, environmental tutela, imperium opus, publicae salutem et tutum domos. In futuro, mobile phones potest vigilo TV et salo in Penitus, TV potest facere phone vocat et salo in Penitus et Computers potest etiam facere phone vocat et vigilia TV.
Integration trium networks potest esse resolvitur rationis ex diversis prospectus et levels, involving technology integration, negotium integration, industria integrationem, terminalis integration, et integration.
Broadband Technology
Pelagus corpus Broadband technology est fibra opticus communicationis technology. Unum ex proposita network convergence est providere unita officia per retiacula. Ut providere unita officia, necesse est habere network platform quod potest sustinere transitum variis multimedia (Streaming Media) Services ut audio et video.
Negotia harum negotiis characteres, magna notitia volumine et alta servitium qualitas requisita, ita plerumque requirere maxima sed in transmissione. Ceterum ex oeconomica perspective, sumptus ne nimis. Et hoc modo, summus capacitatem et sustineri fibra opticum communicationis technology facta est optimus choice ad transmissionem media. In progressionem broadband technology, praesertim optical communicationis technology, providet necessaria Sed, transmissione qualis et humilis sumptus pro transmittendi variis negotiis notitia.
Sicut titulus technology in communicationis agro, optical communicationis technology est developing ad rate of C temporibus incrementum omnis X annis. Fiber opticum transmissione cum ingens facultatem est specimen transmission platform ad "tres retiacula" et pelagus physica carrier de futuris notitia via. Magna facultatem fibra opticum communicationis technology est late applicantur in telecommunications retiacula, computatrum networks, et molestie et televisionem retiacula.
