Embodiment Construction
[0014] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0015] Such as figure 1 As shown, the working principle of ONU transmission is: an electrical signal of a certain code rate is sent from the main chip to the driver chip through a differential line in the form of a modulated signal. After the driver chip processes the received data signal, it will drive the semiconductor laser LD to emit a modulation signal of a corresponding rate. light signal.
[0016] A method for verifying the quality of a 10G EPON asymmetric ONU emission eye diagram, comprising the following steps: S1: analyzing interference sources and interference methods; S2: analyzing potential interference generation links, including BOB drive circuit power system, BOSA device and main chip to drive The modulat...
