RON1512B RFoG ONU
The ACT RON1500B Series is a cost-effective, high-performance RFoG optical network unit (ONU) designed and optimized for standards-compliant RFoG Fiber-to-the-Home (FTTH) networks. It enables cable operators to maximize their existing HFC infrastructure investment while continuing to deliver DOCSIS-based Internet, telephony, and Video-on-Demand services over fiber. As part of ACT’s comprehensive FTTx solution suite, the RON1512 optical node supports 1550 nm forward-path RF transmission and return-path upstream signals at multiple CWDM wavelengths in a 1×32 split FTTH topology. The unit features a low-noise optical receiver and an isolated DFB laser transmitter for stable upstream modulation from set-top boxes (STBs) or DOCSIS modems. An optional PON upgrade port allows seamless convergence with next generation PON systems, providing multiple-system operators (MSOs) with a flexible migration path toward next-generation PON-based FTTH deployments. Designed for bidirectional HFC applications, the RON1500B integrates optical transmit and receive paths over a single fiber, effectively minimizing return-path noise and ensuring high-reliability signal transmission for modern CATV broadband networks.
· Excellent AGC characteristic, when the AGC range is -8 to 0dBm, the output level remain unchanged, CTB and
CSO basically unchanged.
· Optimizing circuit design, SMT production process, optimizing the whole signal path, makes the
photoelectronic signal transmission more stable, RF linear indicators higher.
· Professional RF attenuator circuit, with good attenuation linear and high precision.
· GaAs amplifier device, with good index, low distortion and high reliability.
· The shell adopts aluminum die casting, cooling effect is good and the appearance is exquisite.
· The turning on mode of reverse laser can be set to continuous mode or burst mode.
