3. Technique Parameter

3.1 Link test conditions

Special instructions: The performance parameters of this manual according to the measuring method of GY/T 184-2002 < CATV system analog optical fiber amplifier technical requirements and measuring method>, and tested in the following conditions.
Test condition: With standard optical fiber and standard optical receiver composed the test link. Set 59 PAL-D analog TV channel signal at 550MHz frequency range under the specified link loss. Transmit digital modulation signal at range of 550 MHz ~ 862MHz, the digital modulation signal level (in 8 MHz bandwidth) is 10dB lower than analog signal carrier level. When the input optical power of optical receiver is -1dBm, measure the C/CTB, C/CSO and C/N.
