Application of this fiber optic receiver by TUOLIMA: In the FTTH Triple Play, Data Signal is output through the PON port of the OLT. The CATV Signal is output through 1550 Optical Transmitter, and then passes through an EYDFA Optical Amplifier with the Internal Integrated Splitter, Optical Amplifier, and Combiner Devices, each port output of one fiber with Three Wave Optical Signals, and then though the Optical Distribution Frame(ODF) to user terminal receipt.
If receiving Pure CATV Optical Signal, apply the TLMOR21039D Optical Receiver with 1550nm Filter; if receiving CATV and Data Signals at the same time, apply TLMOR21039W Optical Receiver. The CATV optical signal is converted by the machine to 76dBuv RF signal output, so that the PON optical port can be connected to the ONU to achieve high-speed data access.
