1. Test fiber length is based on the model. For example: 20 km option is tested with 3 m, 10 km and 20 km of SMF28 fiber; 25 km option
is tested with 3 m, 15 km and 25 km of SMF28 fiber.
2. CNR may degrade up to 0.5 dB over the operating temperature range.
3. CSO and CTB may degrade up to 1.5 dB over the temperature range.
4. Test with EDFA, –0 dBm received optical power.
5. QAM format = 256-QAM, ITU-T J.83 Annex C, Analog channels are modulated.
6. L-band input is injected with 2 tones, F1 = 2000 MHz, F2 = 2000.5 MHz with –13 dBm/tone.
7. Test with EDFA, –6 dBm received optical power, QAM format = 64-QAM. 2 tones, F1 = 2000 MHz, F2 = 2000.5 MHz, applied to L-
Band port with –13 dB/tone.
8. Test with EDFA, –8 dBm received optical power, QAM format = 64-QAM. 2 tones, F1 = 2000 MHz, F2 = 2000.5 MHz, applied to L-
Band port with –13 dB/tone.
