Compact optical node, designed for deep fiber networks. Adopt WDM technology, single-fiber dual-wave, with PON loop-out, downstream receiving 1550nm, upstream optical transmission multi-wavelength optional. Using high-performance GaAs amplification module, 1.2GHZ bandwidth, optical AGC, output level 90dBuV. The upstream uses RFOG technology, which can effectively avoid the reverse convergence noise of the CMTS system. Burst and continuous modes are optional. RFOG meets the SCTE-174-2010 standard requirements.
※ Bandwidth up to 1.2 GHz, DOCSIS 3.1 standard comp.
※ Burst Transmitter, SCTE174 compliant .
※ Optical AGC functionality
※ GaAs technology,Output level 80/90dBuV optional.
※ LED indicators for power, optical input and transmit status.
※ Single Fiber WDM technology.
※ Compatible with PON transmission modes.
※ Low power consumption.
※ Flexible powering at local or remote sites.
