Product Description
The XG‐PON ONU transceiver is designed for single mode fiber and operates atwavelength of 1270nm. The transceiver module uses a DFB laser diode and fully compliant withIEC60825 and CDRH class 1 eye safety. It contains APC functions, a temperature compensation circuitto ensure compliance with ITU‐T G987.2 requirements at operating temperature.
The receiver section uses a hermetic packaged APD‐TIA (APD with trans‐impedance amplifier) and a limiting amplifier. The APD converts optical power into electrical current and the current is transformedto voltage by the trans‐impedance amplifier. The differential DATA and /DATA CML data signals areproduced by the limiting amplifier. The APD‐TIA is AC coupled to the limiting amplifier through a lowpass filter.
