Cisco Compatible EPON ONU PX20+ SFP 1310nm TX/1490nm RX 1.25G 20km DDM SC SMF Transceiver Module
Description
The transmitter is designed for single mode fiber and operates at wavelength of 1310nm. The transmitter module uses a FP laser diode and fully compliant with IEC60825 and CDRH class 1 eye safety. It contains APC functions, a temperature compensation circuit to ensure compliance with IEEE802.3 ah™ - 2004 requirement at operating temperature, data inputs and AC or DC coupling circuit.
The receiver section uses a hermetic packaged PIN-TIA (PIN with trans-impedance amplifier) and a limiting amplifier. The PIN converts optical power into electrical current and the current is transformed to voltage by the trans-impedance amplifier. The differential DATA and /DATA CML data signals are produced by the limiting amplifier. The PIN-TIA is AC coupled to the limiting amplifier through a low pass filter.
