Unless otherwise noted, specifications reflect typical performance and are referenced to 68
°F (20°C). Specifications are based
upon measurements made in accordance with SCTE/ANSI standards (where applicable), using standard frequency assignments.
Notes for Optical Section Specifications:
1.
For forward receiver module only. Does not include frequency response contributions from forward optical transmitter.
2.
Minimum receiver RF output level for the stated transmitter percent OMI/ch. (Optical Modulation Index per channel), with
receiver optical input power of 0 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.
receiver optical input power of 0 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.
