Ulwazi

Yintoni isakhiwo senethiwekhi ye-Optical Access Network (OAN) inethiwekhi yokufikelela kwi-Optical (OAN) ibhekisela ekusebenziseni i-fiber optical njengendlela yokuhambisa ingundoqo yokuqonda umsebenzi wokuhambisa ulwazi kwinethiwekhi yokufikelela. Iqhagamshelwe kwindawo yenkonzo ngelayini ye-optical te...

Ngokuphuculwa okuqhubekayo kokwakhiwa kwenethiwekhi ye-high-speed kunye nesidingo sokwakha ubomi obuhlakaniphile bedijithali ngokusekelwe kwizakhono zenethiwekhi "ye-gigabit ezintathu", abaqhubi bafuna imigama emide yokuhanjiswa, i-bandwidths ephezulu, ukuthembeka okunamandla kunye nokusebenza okuphantsi kweshishini Iindleko ...

Uthungelwano lwe-EPON lusebenzisa indlela ye-FTTB ukwenza uthungelwano, kwaye iiyunithi zayo zenethiwekhi ezisisiseko zii-OLT kunye ne-ONU. I-OLT ibonelela ngamazibuko e-PON amaninzi kwizixhobo ze-ofisi ephakathi ukuqhagamshela kwizixhobo ze-ONU; I-ONU sisixhobo somsebenzisi ukubonelela ngedatha ehambelanayo kunye nojongano lwezwi ukuqonda inkonzo yomsebenzisi...

I-ONU (iyunithi yenethiwekhi yokukhanya) indawo yokukhanya. I-ONU yohlulwe kwiyunithi esebenzayo yenethiwekhi ye-optical network kunye nelayibrari ye-passive optical network unit. Ngokuqhelekileyo, izixhobo ezixhotyiswe ngokujongwa kwenethiwekhi kubandakanya i-optical receiver, i-uplink optical transmitter kunye ne-multiple bridge amplifiers ibizwa ngokuba yi-optical node ....

Ngophuhliso lwetekhnoloji yedijithali, itekhnoloji yonxibelelwano lwe-optical kunye nobuchwepheshe besoftware kunye nokusetyenziswa okubanzi kweprotocol ye-TCP/IP, inethiwekhi yonxibelelwano, uthungelwano lwekhompyuter kunye nothungelwano lukamabonwakude luya kudibana kunye kwaye lumanyene phantsi kwe-IP ekwaziyo ukubonelela ngelizwi, ...

I-FTTH i-Fiber Circuit Classification I-transmission layer ye-FTTH yahlulwe yangamacandelo amathathu: i-Duplex (i-dual fiber bidirectional) loop, i-Simplex (i-fiber bidirectional enye) i-loop kunye ne-Triplex (i-fiber enye yeendlela ezintathu) loop. phakathi kwesiphelo seOLT kunye ne-ON...
