Notes: 
1. 
For the Single Forward Receiver, the graph shows receiver RF output level for the stated Optical Modulation Index (OMI) %, with optical 
input power of +3 dBm.  To determine RF output levels at other optical input power, add (or subtract) 2 dB in RF level for each 1 dB 
increase (or decrease) in receiver optical input power. 
2. 
For the High Density Forward Receiver, graph shows receiver RF output level for the stated Optical Modulation Index (OMI) %, with 
optical input power of 0 dBm and receiver RF attenuator set to 0 dB.  To determine RF output levels at other optical input power, add (or 
subtract) 2 dB in RF level for each 1 dB increase (or decrease) in receiver optical input power. 
3. 
Module responsivity 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 chassis.  Specifications are based upon measurements made in accordance with SCTE/ANSI standards (where applicable), using 
standard frequency assignments.
