When mediocrity has seeped so deep that now it's basically a part of your DNA then it becomes bit too futile to pull you out of the little "Allegory of the Cave" you're stuck in.

Every single component of the MIC including academia and FanBois seems to be stuck in "Why should I strive for excellence? X/Y/Z should first do this then only I'll think of". Fine then, enjoy the peace of mind you get by whataboutism.

Someone, somewhere trying to achieve something great would be the only one to ultimately succeed. Maybe not in the first go, maybe not even in the same field they first tried their luck but in the end they'll definitely.

This is what we should be looking at seriously now for if we're not our northern neighbours definitely are & they've already an entire eco system for it.

However, conceptually I can't seem to understand how does having a fibre optic cable not hinder operational efficiency.

I mean if the drone itself flies for 5 kms how does one ensure that much cable is contained within the spool at the launch pad which in itself is a logistical nightmare .

Besides how does one ensure the cable doesn't get entangled within the vegetation or other features while traversing the terrain.

TOW & other such ATGMs faced more or less the same issues before a new generation of Fire & Forget missiles took over.

Would someone with more knowledge shed light on these aspects?

The spool does not lie at the launch pad. The spool is placed on the drone itself. As the drone moves, it releases the cable from the spool. This is also the reason why it doesn't get entangled with vegetation. Because even if goes around a tree 100 times, the drone keeps releasing the cable. As there is no tension, it doesn't get entangled. Essentially the drone releases the cable like a spider releases web from itself.

Not even remotely knowledgeable, but can try my best

Even more interesting is the fact that all that cable is not stored at the launching point, but rather the whole spool is carried by the drone itself. More on that in the next point

Fibre optics cable are relatively light, at just few kilograms per kilometres. But most of that weight comes from protecting cladding and insulation, not the fibre itself. In missiles or drone, you don't need that much protection for a single use item so the ultimate weight is extremely low.

Now coming to this; if the spool is on the launcher

and it gets tangled then the result would be a fibre fixed at one end to the tree and the UAV on the other. A force (the drone pulling it) is being applied to this fixed length of fibre; resulting in it getting yielded.
Now let's assume the spool's on the UAV

again one end gets fixed but the other end is not, rather the spool is fixed. So instead of breaking, the fibre'll simply reel out more and continue.

This is the reason why since the inception of wire guided ATGMs, the wire's always in the missile itself.

You can see the copper spool below the red rocket motor.

The biggest problem with fibre optics cable is not it's length but rather the consequences of a longer length. In case of electricity transmission lines we have poles at ever 100 or 500m so that the cable doesn't sag. But in case of fibre optic, there's no intermediate support; just a 4-5km long cable dangling between two points. If you increase this length too much then it'll sag enough to touch the ground and this can cause issues because now instead of getting taut at one point, the fibres starts to drag on rough surfaces
