like in fiber optic cable we are using laser diode we can also use LED ..so which type of LED will match with the ratings of 13T/15R laser diode?

If you want acceptable coupling you'll need to match the NA of the fibre and the source. A laser has an NA close to that of the fibre, an LED does not. You will need additional optics.

Look up the dominant laser wavelength ie frequency and buy an LED with the same wavelength.

A Laser Diode and an LED are 2 totally different things. You cannot replace one with the other.

What kind of application is this being used on? If it's for fiberoptics then it all depends on the receiver being used and what specs it is looing for from the light being transmitted through the cable.
