    I am developing a device that will communicate with a Pocket PC IR port. What
    is the nominal wavelength for these ports? Most devices (IR LEDs and
    Photodiodes) fall into two broad categories: 880nm and 950nm. Which one is
    appropriate for the Pocket PC? There may be enough response to use either one,
    but I would rather be right in the middle of the filter passband than sitting on
    the side.

    850 to 900 mn for IrDA.
    880 mn would be best.
