Notes
:
1. Reverse receiver (Rx) maximum output level is determined using 5 to 42 MHz noise
loading while ensuring that the link Noise Power Ratio (NPR) dynamic range is not Rx
limited. Rx RF attenuation may be needed to avoid exceeding maximum Rx output level
in operation. See Calculating Reverse Receiver RF Output Level on page 2.

in operation. See Calculating Reverse Receiver RF Output Level on page 2.
2. RF Attenuation control: software control is via LCI, ICIM, or ROSA / TNCS.

3. Optical AGC range above and below nominal optical input power is determined by the
initial RF attenuation setting. See Understanding Optical AGC Range on page 3.
4. Module responsivity is measured at 1310 nm with 0 dB RF attenuation, and may change
at other wavelengths.
Unless otherwise noted, specifications reflect typical performance and are referenced to the
ambient air temperature at the inlet to the Prisma II standard or Prisma II XD chassis.
Specifications are based on measurements made according to SCTE/ANSI standards (where
applicable), using standard frequency assignments.
