Hmmm... The more recent laying of fiber isn't as optimal as the previous.
The newer fiber cores are not laid in an optimal distance due to the path used. The new core is laid in metal trunking along the ceiling of pavements at ground level of block and goes down at some specific ends of the block to go underground and crosses the carpark road to the next block.
While fiber is not as sensitive to distance as copper (due to the signal is different nature), I do two concerns:
Concern 1: Will the above discrepancy results in slightly higher latency (e.g. few milliseconds)?
Concern 2: Will the above mentioned discrepancy results in a disadvantage to newer OpCos?
1. latency unlikely to increase by much, considering that light can travel 1km in 1/299800second. 1ms by comparison is 1/1000
2. maybe of concern will be path-loss esp at the biggest exchange here aka amk
