The first Indian manufacturer to create guidance optical fibre wires for torpedoes
Guidance optical fibre wires have always been imported into the country, leading to very high costs. However, this is a highly essential component in torpedoes, as the guidance optical fibre wire gives the torpedo inputs on how to reach the assigned target.
APAR became the first Indian manufacturer to develop guidance optical fibre wires. In fact, very few international manufacturers have been able to develop these products.
The product itself had very specific demands that it needed to fulfil, as it was used by the Indian Defense. The wire needs to be wound with a special tangle-free winding technique, as it needs to unravel during the torpedoes underwater run. This requires extremely high strength, as the fibre optic wire needs to unravel at a rate of 25 metres per second. Very precise production techniques were used to achieve this.
As a result of APAR producing indigenously, costs went down while quality remained the same.
