Abstract

The invention discloses a GPON (gigabit passive optical network) remote system and a digital diagnosis method and relates to the field of GPON remote systems. The GPON remote system comprises a GPON system-on-chip and a BOSA (bidirectional optical sub-assembly) drive circuit. The GPON system-on-chip is connected with the BOSA drive circuit through an I2C (inter-integrated circuit) interface and a serial-to-parallel interface. The BOSA drive circuit comprises a BOSA, a drive chip and a booster circuit. The BOSA comprises a laser, a detector and a beam splitter. The drive chip comprises a DAC (digital-to-analog converter), a laser drive module, an automatic power control module, an automatic gain control module, a limiting amplifier, an ADC (analog-to-digital converter), a register, and a first I2C interface. The GPON system-on-chip comprises a PON interface module, a CPU (central processing unit), the serial-to-parallel interface and a second I2C interface. The GPON remote system allows for simpler reporting process of digital analysis and higher analog-to-digital conversion precision of an optical interface acquisition circuit, and is compatible with traditional optical module GPON remote systems.

Description

technical field

[0001] The present invention relates to the field of GPON (Gigabit-Capable Passive Optical Network, Gigabit-Capable Passive Optical Network) remote system, in particular to a GPON remote system and a digital diagnosis method. Background technique

[0002] At present, the mainstream PON (Passive Optical Network, Passive Optical Network) technology has made significant progress and has begun to be deployed on a large scale. EPON (Ethernet Passive Optical Network, Ethernet Passive Optical Network) and GPON technologies are approaching the same in terms of technical standards, equipment functions and performance. With the large-scale collection of GPON remote systems by telecom operators such as China Mobile, the trend of GPON remote equipment costs approaching the cost of EPON remote equipment has become increasingly clear, which puts forward severe cost reduction requirements for equipment suppliers. Since the cost of optical modules in GPON remote systems acc...
