4.1 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.
