E: Several manufacturers are developing regenerator technologies that will allow signals to be transmitted many times farther than at present before requiring regeneration.

我觉得这句话的意思应该是：几家制造商都在发展转化器的科技---可以允许信号传播的比现在在转换器之前的传播更远几倍。

那么当然削弱啊，结论是说Therefore, Light-line is one of the companies that will most benefit if new long-distance fiber-optic telecommunications networks are constructed.

有几家公司可以发展不要转换器就更远那还要转换器干嘛？就算最后还是需要转换器，因为这种尝试不要转换器，LL公司也不可能最受益啊。

我是这么理解的。

But the new technology is a kind of regenerator technology, so they still have to use regenerator ...

Yeah we still need the regenerator, but the 'regeneration' frequency can be reduced.
That's what E said.
For example, at present, before requiring regeneration , the signal can travel 100m, then it can travel another 100m once the regeneration is made. So if the signal is going through a 1000m fiber-line, it will be regenerated 9 times.
The new technology, however, can make the signal travel 500m before the first regeneration. And after the first regeneration, it can travel another 500m. Thus, to pass through a 1000m fiber-line, it only takes regeneration once.
As a result, even the fiber-line is longer than now, the demand for regenerator will not increase thanks to the anvanced techonology.
Imagine you are running a 1000m race. When you were weak, you had to drink 9 bottles of water. Now you become so strong that even you are running a 5000m race, you just need to drink 5 bottles of water.
So people who sell water to you will not make more money on you.
