Optical module of dual-mode optical network unit
The model of said LD is specially: ML720AG11S or ML720AA47S or 131D-02J-LCT11-07.
The invention discloses an optical module of a dual-mode optical network unit. The optical module comprises a laser diode LD, a driving circuit of the LD, an avalanche photoelectric diode APD, a trans-impedance amplifier TIA and an amplitude-limiting amplifying circuit, wherein the amplitude-limiting amplifying circuit is provided with a self-adaptive filter and is used for receiving differential electric signals with different rates output by the TIA in an automatic matching manner. The optical module disclosed by the invention has the advantages that the amplitude-limiting amplifying circuit with the self-adaptive filter is adopted, the signal with the rate being 1.25G or 2.5G can be received, processed and amplified in a self-adaptive manner, so that the optical module not only can be applied in a GPON (Gigabit Passive Optical Network) to receive the signal with the rate being 2.5G, but also can be applied in an EPON (Ethernet Passive Optical Network) to receive the signal with the rate being 1.25G.
