The time delays shown in the table above are one way values. They have been calculated using the speed of light through fibre cable (5us/Km). Actual measurements made over the longest paths of the cable showed that the values were within 1 m/s of the calculated values, therefore using the above table the actual delays over any path can be calculated. Time delays caused by the equipment are negligible compared to the segment delays.

Notes

*: Nedonna is not an Access Point. Nedonna cable station contains optical pass through cross connections to the WDM Submarine Line Terminal Equipment and does not provide network access.

#: Segments F2 & F3 use the same physical path.
