However, the electrical and optical performance specified in this document may not be guaranteed. 4) The receiver may be damaged if not powered up and powered down in the correct order. When powering up the device, turn on APD bias (Vapd) first, then positive supply (Vcc). Power down in reverse order. 5) Vbr of individual device at given operating temperature is not to be exceeded.
