         The NPDU-P-32 is compliant for all ANSI compliant 19-inch relay rack/cabinet/frame mounting environments and utilizes a single 1-rack unit (1.75-inch) of space.  Due to the low power requirements for the ONTs, the NPDU-P-32 family has no thermal output and does not require any venting or airflow.  It is ideal for enclosed ceiling/floor zone box enclosures common in a Passive Optical LAN design and deployment.

         This solution eliminates the need for local powering of the PON ONTs or the alternative need to provide a battery backup unit (BBU) at each ONT location and the subsequent management and replacement of expensive Lithium Ion batteries. This allows for cost effective centralized backup of the entire PON system, with minimal impact (less than 5%) to the traditional PON CapEx savings realized in current deployments (typically between 50 and 75% savings in cabling and Active electronics over copper and packet switching).
