Zhejiang BC&TV Technology Co., Ltd.Zhejiang BC&TV Technology Co., Ltd.
1. Frequency of internal modulation optical transmitter is 47-2605 MHz. This equipment is applied to transmitting cable TV signal in the frequency range of 47-862 MHz, transmistting satellite intermediate frequency signal in the frequency range of 950 ~ 2605MHz. It is often used to help EDFA realize IP QAM and narrowcast. The working range is general within 10 km(Max 20 km).
2. It dopts original DFB laser with low noise as optical source.
3. Input level can be controlled and can adapt different RF input so that the machine can still keep the best condition.
4.RJ45 Ethernet interface supports the SNMP protocol. So it is easy to realize the remote network management functions.
5. It adopts switch power supply with 100 ~ 240V.
6. Using digital tube display, three key design, with good man-machine interface.
7. This machine is equipped with microprocessor software, with laser monitoring, digital tube display, fault alarm, network management and so on. It will alarm as soon as the laser work parameters deviated from the software stated allowing scope.
