Abstract

The invention relates to a device for preventing an upstream signal from colliding, which is suitable for a time division multiplexing passive optical network. The device comprises an optical coupling device, a photoelectric transducer, a control system and a photoelectric signal switching module, wherein the photoelectric transducer is coupled with the optical coupling device; the control system is coupled with the photoelectric transducer; and the photoelectric signal switching module is coupled with the optical coupling device and the control system. The optical coupling device is used for receiving a first optical signal and dividing the first optical signal into a second optical signal and a third optical signal. The photoelectric transducer is used for converting the second optical signal into a first electric signal; and the control system generates a control signal according to the first electric signal. The photoelectric signal switching module decides whether to block the third optical signal from passing through the device or not according to the control signal.

Description

technical field [0001] The present invention relates to a time division multiplexing (Time Division Multiplexing, TDM) optical network system, device and method for preventing signal collisions, and in particular to a time division multiplexing optical passive optical network (TDM Passive Optical Network, TDMPON) system, device and method thereof. Background technique [0002] With the increase of network users, the amount of data transmission also increases. The traditional technology of using electrical signals for communication will cause network congestion due to the bandwidth limitation of electrical signals. Therefore, many network service providers use optical fiber communication to provide network services to various network users with different needs. [0003] The bandwidth of optical fiber communication technology is larger than that of wireless communication or wired communication using electrical signals, so it can transmit a larger amount of data and provide u...
