1.2 GHz RFoG Node FTTx Solution
ACT 1.2 GHz RON1510D series RFoG (RF over Glass) ONU is a cost-effective and superior performance optical network unit, which is designed and optimized to work in a DOCSIS standards-compliant, OBI free RFoG Fiber-to-the-Home (FTTH) architecture. RON1510D provides excellent forward and reverse path performance combined with high reliability and a user-friendly layout. It is designed with 1550 nm forward-path RF signals, and 16 return-path upstream signals at 1450, 1470, 1590, 1610nm region. Each unit can be adjusted with 4 output optical wavelengths (0.5nm stepping) at these four regions electronically. The RON1510D optical node is part of ACT overall FTTx solution suite. RON1510 features an optical AGC function in the forward path to ensure the same RF output level in every home. The return transmitter has burst mode (turns on the laser by return signal) to greatly reduce return fibers. It incorporates a low noise optical receiver and an isolated DFB optical laser to modulate the return-path signal from any set-top box (STB) or DOCSIS modem onto the fiber.
· Operating frequency: 5 to 85/110 - 1218MHz; support smoothly update on the spot (5 to 204/258 - 1218MHz)
· Support optical AGC downstream, whose control range is 0 to -5/-6/-7/-8dBm adjustable
· Adopt electric adjusting mode for both EQ and ATT circuit, using LED displaying screen to modify directly
· Output wavelength of the return path is adjustable, 4 wavelengths settable with 0.5nm stepping
· RFoG can be set as burst mode or continuous mode
· Support DOCSIS 3.1 system and OBI Free
