• Adopt E-O low noise hi-sensitivity PIN optical demodulator, PHILIPS / MOTOROLA power doubler amplify module., make sure the best index.
• Matched with the direct current steady power supply.
Special elucidation: Equipments technique parameter the manual given is according to the test method of GY/T143-2000 CATV system amplitude modulation laser transmitter and receiver enter the net technique condition and measure method, and gained under its prescriptive test condition. Test condition: Test link path is formed of standard fiber and standard optical receiver. Under the condition of prescriptive link loss, set 59 PAL-D imitate TV channels signal at 550MHz, transmit digital modulated signal at the range of 550MHz-750(862) MHz, level of digital modulated signal (8MHz band width) is lower 10dB than of imitate signal carrier wave, when optical receiver input optical power being -1dBm, measure C/ CTB, C/ CSO, C/ N.
