Problems solved by technology

When the CPE is down or cannot operate normally, the CPE cannot receive the download command, so that the CTO cannot use the download command to shut down the CPE, and can only assign engineering personnel to shut down the abnormal CPE, which makes system maintenance quite inconvenient

Embodiment Construction

[0053] This case will be fully understood by the following examples, so that those skilled in the art can complete it, but the implementation of this case cannot be limited by the following implementation examples. Wherein the same reference numerals always represent the same components.

[0054] Please refer to figure 2 , is a device embodiment of the present invention. figure 2 The detection device 20 includes a laser device 21 , a detector 22 and a processor 23 , wherein the detector 22 is coupled to the laser device 21 , and the processor 23 is coupled to the detector 22 .

[0055] Generally speaking, the laser device 21 is a bi-directional optical sub-assembly (Bi-directional Optical Sub Assembly, BOSA) commonly used in the optical fiber network at the customer end, which includes a laser diode (LD) 211 and a monitoring optical diode (MPD) 212. The LD 211 is an analog component, and its characteristics will change with the external environment such as temperature. Ther...

Abstract

This invention provides a detecting device and a method for a passive optical network (PON), which includes: a laser device; a detector coupled to the laser device and generating an output signal at one of a first level when the laser device emits light and a second level when the laser device does not emit light; and a processor repeatedly detecting the output signal in a fixed period, and simultaneously counting a total number of changes that the output signal changes from the first level to the second level and the output signal changes from the second level to the first level so as to detect whether a light leakage occurs in the PON.

Description

technical field [0001] The invention relates to a detection device and method, in particular to a detection device and method for detecting light leakage in a passive optical fiber network. Background technique [0002] Whether it is ADSL or optical communication network, the traditional network architecture is a point-to-point (Point-to-Point) architecture, that is, the system end (computer room) and client equipment (CPE), such as the line from the ADSL computer room to the user's home . In order to reduce costs and achieve more applications, an architecture called Passive Optical Network (PON) has emerged in optical fiber networks, which can support the capabilities of the system (CTO) side and support one-to-three-two (1-to-32 ) to a pair of sixty-four (1-to-64) clients. In the past, xDSL series were criticized because the distance between the computer room and the client was about 150 meters, and the distance from the CTO end to the CPE end of the optical fiber networ...
