- OTDR qhov ntsuas hauv paus: tsim kom muaj cov cim qhia tam sim no, thaum lub teeb liab - rau - suab nrov piv yog qhov zoo
5G Mobile Backhaul thiab PON Convergence Opportunity
XGS-PON thiab tom ntej- tiam PON tau siv ntau dua li cov xov tooj ntawm tes rov qab rau 5G tes hauj lwm. Ib qho chaw OLT nkaus xwb tuaj yeem rov qab tau ntau lub 5G me me tib lub sijhawm, siv tib lub ODN infrastructure uas ua haujlwm rau cov neeg nyob hauv. Cov ntaub ntawv siv rov qab muab cov kev xav tau sib txawv ntawm ODN:
- Latency:5G fronthaul (CPRI/eCPRI) xav tau<100 µs one-way latency; XGS-PON supports this with proper timing configuration
- Muaj:Cov xov tooj me me backhaul tau muab cais ua cov txheej txheem tseem ceeb; enclosure thiab connector specifications yuav tsum txhawb kev txij nkawm- ua haujlwm pub dawb rau 5+ xyoo
- Symmetry:XGS-PON's symmetrical 10/10G muaj peev xwm tshwj xeeb yog haum rau cov qauv tsheb hauv ntej; GPON's asymmetric 2.5G sab sauv yog lub hauv paus rau eCPRI
