AON121 Mini Node

AON121 Series FTTH mini node supports Video Overlay application over FTTH optical fiber access network. It operates on 1218MHz RF bandwidth, with high output power up to 83 dBµV (AGC). AON121 has low power consumption and optional built-in WDM to support PON signal pass-through. It is part of ACT Deep Fiber and FTTH solution, which helps operators provide superior video services in a FTTH PON network architecture.

·       1002 or 1218 MHz RF Spectrum for superior video services
·       Small form factor and low power consumption
·       Low noise circuit (3.5 % modulate, -10 dBm receive, CNR ≥ 42dB)
·       High output power up to 83 dBµV for MDU application
·       Excellent linearity at wider optical receiving range +2 dBm to -20 dBm
·       Flatness less than ±1.0 dB in the range of 47 MHz to 1218 MHz
·       Metal shell, supply safeguards to opto-electrical sensing device
·       Optional built-in WDM provides PON pass-through capability in a FTTH optical passive network
·       Powered directly using the power adaptor
·       The compact enclosure fits easily in CPE, ONU housing or network termination boxes
