WR8602 PIN
1310nm, optical receiver with DIODA PIN, SC/APC connector, 2 out RFx102dBuV (1 Philips hybrid.
| Performance characteristics • Adopt US E-O high-performance optical receiver module, field water-repellent shell. • Adopt Philips low-noise microwave tube pre-amplifier circuit and power doubler (or push-pull) output module. • Built-in continuous adjustable equalizer and attenuator, plug-pull output brancher component, 8-class optical power display. • Strict anti-thunder system, and high-reliability switch power. • Suitable for middle or small CATV network. | ||
| Link path test condition 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. | ||
