AI Technical Summary

Problems solved by technology

This will inevitably increase the operation and maintenance costs of operators or cable companies
And it will definitely take a long time from removal to reinstallation
More importantly, due to the removal of the CATV module in the ONU (and the ONU is likely to be a device purchased by the user), it is likely to bring many economic problems that lead to legal disputes

Embodiment Construction

[0032] figure 1 The shown ONU with CATV control function is one of the embodiments of the present invention, and it is composed of an optical network unit (ONU), a CATV module located on the ONU side, and a CATV power supply module located on the ONU side and providing voltage to the CATV module. Among them, the ONU has a control interface for controlling the switch of the CATV power supply module. We define a GPIO pin of the ONU chip, that is, the CATVCTL pin as the control interface. The CATV is controlled by outputting a high level or a low level through the GPIO pin. The switch of the power module. The CATV module is composed of a CATV optical signal receiving unit, a photoelectric conversion unit and a CATV analog signal output unit to realize the reception and processing of CATV signals. The CATV power supply module connected with the CATV module is responsible for providing voltage to the CATV module. We choose a chip with a shutdown function as the CATV power supply m...

Abstract

The provided control method for CATV business in EPON comprises: the CATV control module in OLT communicates with ONU to control its interface and then the connected power supply module for CATV for final control on CATV business.

Description

technical field [0001] The invention relates to the field of optical fiber communication, in particular to a method and a device for controlling user cable TV (CATV) services in a gigabit Ethernet passive optical network (EPON). Background technique [0002] Ethernet has many advantages such as mature technology, low price, simple operation, and easy maintenance. Since its birth, Ethernet has occupied an absolute dominant position in local area network (LAN) technology. With the introduction of Gigabit Ethernet and 10G Ethernet standards, Ethernet has made a qualitative leap in terms of bandwidth capability and service quality (QoS) guarantee. Ethernet is gradually entering the Metropolitan Area Network (MAN) and Wide Area Network (WAN) from the LAN. The Gigabit Ethernet Passive Optical Network (EPON) is a key player in the access network field because it can be seamlessly connected to a large number of enterprise LANs using Ethernet technology and emerging Ethernet-based M...
