What is the mean of Physical reach in FTTH technology? |
|
Answer» Physical reach is defined as the maximum physical distance that can be achieved for a particular transmission system. Since, ‘Physical Reach’ is the maximum physical distance between the ONU/ONT and the OLT. However, in GPON, two options are defined for the physical reach: 10 kms, and 20 kms. It is assumed that 10 km is the maximum distance over which FP-LD can be used in the ONU for high bit rates such as 1.25 Gbit/s or above. |
