Notes:
1. Forward performance is for station from output of optical Rx to node RF output port, with 0 dB pad in optical interface board (OIB), any
forward configuration module, 3 dB interstage (I/S) pad, 7.5 dB linear I/S EQ, factory select output pad, and signal director jumper.
Includes OIB losses.
2. Reference output tilt and internal tilt are both “Linear” tilt.
3. The forward reference output tilt specified is achieved via field installation of appropriate linear I/S EQ, in conjunction with the internal tilt
of the launch amplifier and the tilt associated with the optical link (transmitter/receiver combination).
4. Stated distortion performance is for launch amplifier section operated at reference output levels and tilts. Full station performance can be
determined by combining optic performance and launch amplifier performance.
5. Reverse performance is for station from reverse input port to input of reverse optical transmitter module, with 0 dB reverse input pad.
6. “Digital” refers to 550 - 1002 MHz loading with QAM carriers at -6 dB relative to analog video carrier levels.
7. “Digital” refers to 650 - 1002 MHz loading with QAM carriers at -6 dB relative to analog video carrier levels.
8. X-mod (@ 15.75 kHz) specified using 100% synchronous modulation and frequency-selective measurement device.
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.
