For reverse optical transmitter and link performance, see the “Analog Reverse Optical Transmitters with Thermal Compensation” data sheet.
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.
1.
Receiver (Rx) has a 2-position RF attenuator switch (-6 dB and 0 dB). The -6 dB setting is used for 0 to +2 dBm optical Rx
power, the 0 dB setting is used for -3 to 0 dBm Rx power.
power, the 0 dB setting is used for -3 to 0 dBm Rx power.
2.
For forward receiver module only. Does not include frequency response contributions from forward optical transmitter.
3.
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, and specified Rx attenuator setting. 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, and specified Rx attenuator setting. 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.
