Note: In the IEEE standard, it suggests the available transmission distance is 2km for
62.5/125um fiber optical cable in 1310nm wave length. Actually, the attenuation of
Multi-Mode 62.5/125um optical fiber cable is 1.5dBm/km and the maximum link distance
can up to 4 to 5km.
The IEEE organization recommends maximum optical fiber cable distances as defined in the
following table.
