GPON ONU AND RECEIVER TWO-IN-ONE GDONU300-2030B

Overview    GDONU300-2030B is FTTH slaver combined GPON ONU and CATV optical receiver in one box. GDONU300-2030B series are optical network terminal targeting FTTH networking strategy. GDONU300-2030B includes a variety of models covering GPON SFU data type and double optical fiber type. The double optical fiber type is composed of CATV optical receiver and ONU; CATV optical receiver has the feature of low optical power receiving while ONU adopts compatible chips with GPON. In all, this series is well positioned to fulfill different FTTH networking requirement, providing reliable and secure service that come in all varieties. Features        ONU :
● Has a range up to 20KM, follow the ITU-T G.984 standard
● Supports second-layer data package transmission in full wire-speed
● Provide 4 10/100M Base-T self-adaptive RJ45 interfaces, which can be used to such devices as computers and set top box.
● Supports local web management as well as remote web management.
       Optical Receiver:
● Supports double fiber access; the uplink operating wavelength for PON is 1310nm, downlink wavelength is 1490nm;
● CATV’s operating wavelength is 1550nm.
● Support CATV low optical power receiving; light-operated AGC-15~-5dBm or -10~0dBm stable RF output.
● Users can remote monitor the CATV status ,the received power and the output power of the optical receiver can be captured by the Lootom EMS system. Technical Specifications        ONU?Basic?Parameter:
