RON1512 1.2G Node

Ascent RON1512 is a compact, high-performance 1.2 GHz two-way optical node designed for DOCSIS FTTH architectures. Engineered for superior forward and return path performance, it combines high reliability, simplified installation, and a user-friendly layout. The integrated optical AGC automatically maintains a consistent RF output level in every home, while the burst-mode return transmitter activates the laser only when a return signal is detected. As part of ACT’s FTTx solution suite, the RON1512 supports 1550 nm forward-path RF transmission and 1610 nm return-path upstream signals. It integrates a low-noise optical receiver and an isolated DFB laser to modulate return-path signals from set-top boxes (STBs) or DOCSIS modems onto the fiber. Utilizing single-fiber WDM transmission, the RON1512 supports both data and analog signal transport, ensuring seamless operation within existing HFC network infrastructures. Its simplified network structure reduces active components, enhances overall reliability, and lowers operational costs. Fully compliant with the SCTE 174 2010 standard, the RON1512 delivers a cost-effective, standards-based solution for next-generation RFoG and FTTH deployments.
