Compact optical node, designed for deep fiber networks. Adopt WDM technology, single-fiber dual-wave, downstream receiving 1550nm, upstream optical transmission multi-wavelength optional. Using high-performance GaAs amplification module, 1.2GHZ bandwidth, optical AGC, output level up to 108dBuV. 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. The built-in display and buttons make it easy to query and set parameters.
● 1.2GHZ frequency band, multiple frequency divisions are optional.
● Optical AGC巷帝，control range -5/-6/-7/-8～0 adjustable.
● Electronic control RF ATT：0～18往湿，1dB stepping.
● Electronic control EQ：0～15，1dB stepping.
● Downstream output level can reach 108dBμV.
● Upstream output optical power 2mW, burst, continuous mode optional.
● LED can display and set various parameters.
● Excellent output distortion index.
● Built-in WDM, single fiber dual wave.
● Excellent surge and ESD protection.
