Izinto eziluncedo kunye nezingalunganga ze-XGPON kunye neGPON

I-XGPON kunye ne-GPON nganye ineenzuzo kunye neengxaki zayo kwaye zifanelekile kwiimeko ezahlukeneyo zesicelo.

Izinto eziluncedo ze XGPON ziquka:

I-1.Izinga lokudluliselwa okuphezulu: I-XGPON inikezela ukuya kwi-10 Gbps ye-downlink bandwidth kunye ne-2.5 Gbps ye-uplink bandwidth, ifanelekile kwiimeko zesicelo kunye nemfuno ephezulu yokuhanjiswa kwedatha ye-high-speed.

I-2.Ubuchwephesha bokumodareyitha obuphezulu: I-XGPON isebenzisa iteknoloji yokumodareyitha ephakamileyo efana ne-QAM-128 kunye ne-QPSK ukuphucula umgangatho kunye nomgama wokuhanjiswa kwesignali.

I-3.I-intanethi ebanzi: Umlinganiselo wokwahlula we-XGPON unokufikelela kwi-1:128 okanye ngaphezulu, ukuvumela ukuba igubungele indawo yothungelwano olubanzi.

Nangona kunjalo, i-XGPON ikwanazo ezinye izinto ezingalunganga:

I-1.Ixabiso eliphezulu: Ngenxa yokuba i-XGPON isebenzisa ubuchwepheshe obuphezulu kunye nezixhobo eziphezulu ze-frequency, ixabiso layo liphezulu kwaye lisenokungafaneleki kwiimeko zesicelo ezingabizi kakhulu.

Iinzuzo zeGPONikakhulu ziquka:

1.Isantya esiphezulu kunye ne-bandwidth ephezulu:I-GPON inokubonelela ngemilinganiselo yokuhanjiswa kwe-1.25 Gbps (isalathiso esisezantsi) kunye ne-2.5 Gbps (isalathiso esinyukayo) ukuhlangabezana neemfuno zabasebenzisi zoqhagamshelwano oluphezulu lwe-broadband.

2.Umgama omde wothumelo:Ukuhanjiswa kwefayibha ye-Optical ivumela imigama yokuhanjiswa komqondiso ukufikelela kumashumi eekhilomitha, ihlangabezana noluhlu olubanzi lweemfuno ze-topology yenethiwekhi.

3.I-Symmetric kunye ne-asymmetric transmission:I-GPON isekela ukuhanjiswa kwe-symmetric kunye ne-asymmetric, oko kukuthi, amazinga okuhanjiswa kwe-uplink kunye ne-downlink angahluka, okuvumela inethiwekhi ukuba ilungelelanise kakuhle iimfuno zabasebenzisi abahlukeneyo kunye nezicelo.

4.Ulwakhiwo lwezakhiwo:I-GPON yamkela i-point-to-multipoint optical fiber transmission architecture kwaye idibanisa iitheminali zomgca wokukhanya (OLT) kunye neeyunithi ezininzi ze-optical network (ONUs) ngokusebenzisa umgca we-fiber optical, ukuphucula ukusetyenziswa kwemithombo yenethiwekhi.

5.Ixabiso lilonke lesixhobo lisezantsi:Ekubeni izinga le-uplink liphantsi, iindleko ze-ONU zokuthumela amacandelo (ezifana ne-lasers) nazo ziphantsi, ngoko ke ixabiso elipheleleyo lesixhobo liphantsi.

Ukungalungi kwe-GPON kukuba iyacotha kune-XGPON kwaye isenokungalungeli iimeko zesicelo ezifuna uthumelo lwedatha ephezulu kakhulu.

Isishwankathelo, i-XGPON kunye ne-GPON nganye ineenzuzo zabo kunye nokungalunganga kwaye zifanelekile kwiimeko ezahlukeneyo zesicelo.I-XGPON ifanelekile kwiimeko zesicelo kunye nemfuno ephezulu yokuhanjiswa kwedatha ye-high-speed, njengamashishini amakhulu, amaziko edatha, njl.;ngelixa i-GPON ifaneleka ngakumbi kwiimeko zokufikelela ezisisiseko zothungelwano lwasekhaya kunye nolweshishini ukuhlangabezana neemfuno zenethiwekhi yemihla ngemihla.Xa ukhetha itekhnoloji yenethiwekhi, izinto ezinje ngemfuno, iindleko, kunye neemfuno zobugcisa kufuneka ziqwalaselwe.
