I work with SLED (superluminiscent light-emitting diodes). Datasheet said me that I must to avoid electrostatic discharges when I work with SLED. So I want to connect cathode with anode of SLED and will begin to mount SLED. It will be enough for safe operations (without electrostatic discharges) with SLED?
Perhaps you need an ESD wrist band:
Those go on your arm, as you certainly have guessed. The terminal should be connected to a ground potential through 1 Mega-ohm resistor. Don't connect to ground directly as suggested in comments, unless you have high tolerance to electric shocks. Use a ESD plug:
