OLT&Core Network Design

FTTH service ကိုေပးဖို႔ အေျခခံ Device ေတြကေတာ့
OLT ကေန Switch
Switch ကေန BRAS
BRAS ကေနမွ NAS/Radius Server ကို Connect ထားေလ့ရွိပါတယ္
ISP Design အေပၚမူတည္၍ အေျပာင္အလဲလည္းရွိနိင္ပါတယ္

OLT & Fibre Technology

OLT ကေန Splitter ေတြ ODF/ODM ေတြခံၿပီးCustomer ေတြကိုေပးေလ့ရွိပါတယ္
Example :POM port တစ္ခုမွာ Fiber Splitter(16,31,64) ခံၿပီးေတာ့ ခြဲၿပီးသံုးပါတယ္
SC Fiber Cable Type ကို အသံုးျပဳပါတယ္

OLT Physical Detail

OLT မွာ Frame/Slot/Port ဆိုၿပီးရွိပါတယ္ဗ်
Slot တစ္ခုမွာ Pon Port ေပါင္း 15 Ports ပါပါတယ္ဗ်
Slot 16 ခုအထိ ထပ္ထိုးၿပီး ၿပီးထည့္အသံုးျပဳလို႔ရတယ္

What is GPon And OLT

GPON(Gigabit Passive Optical Network)
ကေတာ့ High Bandwidth Share Fiber Access Technology လို႔ မွတ္လို႔ရပါတယ္

OLT (Optical Line Terminal)  Device ကို ISP ေတြရ႔ဲ
FTTH service မွာ အဓိက အသံုးျပဳၾကပါတယ္
