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.
