| Features
1) Optical Transmitter part adopts the latest imported brand high performance DFB laser; provide high quality signal transmission for the CATV network.
2) Optical receiver part adopts the latest imported brand-name optoelectronic integrated receiver module;
3) Build-in RF driver amplifier and control circuit to ensure the low noise and inter-modulation index; it can output two ways high quality RF signal to cover the local users.
4) Perfect and reliable optical power output stabilizing circuit and built-in high-power electric heating cooler, enable the working ambient temperature difference up to ± 40 ° C, ensure the best performance of the machine and the long life steady operation of the laser.
5) LCD status display, the main working parameters are clear at a glance.
6) Compact and reasonable process structure, convenient installation and debugging, stable and reliable performance.
7) The equipment can work steadily outdoor under bad environmental condition, because of large cast aluminum waterproof case, high reliability switching power supply and strict lightning protection system.
