ZBL-ON-300ACT mini optical node (OBI-free) is a bi-directional optical node by WDM transmission, which is the ideal platform for delivering video (digital or analog) as well as high-speed data services over advanced hybrid fiber/coax (HFC) network; this optical node combines the superior proven technologies of both the RF amplifier and optical components.
It has -6～+2dBm optical AGC and reasonable level output with 5±2dB slope.
In the return path, each Node can provide 8 or 16 stable Laser wavelength by 0.5nm or 0.25nm step for choice, Automatic Optical Control is designed on the circuit that reduces the return noise effectively, to lower the power consumption and prolong the working life.
ZBL-ON-300ACT is compact in size, high performance and high reliability, and can provide the full complement of functions required by advanced networks.
