Light repeater of light-network 650nm information transmission system

Abstract

The invention comprises a power translating circuit, an optical module power processing circuit, an optical module IP1 and an optical module IP2. The power translating circuit is used to translate a 220v AV voltage into a +5v DC voltage; the optical fiber module power processing module is connected to the +5v DC voltage outputting circuit; the optical fiber module IP1 and the optical fiber module IP2 are separately connected to its corresponding output of optical fiber power processing circuit; the output and the input of the optical fiber module IP1 are respectively connected to the output and input of the optical fiber module IP2. After the 1550nm,1310nm,850nm silicon optical fiber signals are converted into the 650nm plastic optical fiber signals, the end user over 50m transmission distance can get replay and amplification.

Description

technical field [0001] The present invention relates to a network device, in particular to a user terminal device of an optical network, which is commonly known as the "last mile" user terminal device. Background technique [0002] The quartz optical fiber network information on the existing main line must undergo optical / electrical and electrical / optical conversion when it is connected to the user terminal. This conversion process not only affects the transmission speed, but also causes signal attenuation, information distortion, and is susceptible to external interference. It is also prone to information theft. [0003] In order to change the above-mentioned defects in the existing information transmission, an all-optical network is being studied. The all-optical network has become the next generation of high-speed (ultra-high-speed) broadband with its good transparency, wavelength routing characteristics, compatibility and scalability. The network's first choice. In ord...

Problems solved by technology

In order to transmit information by light at the user terminal, that is, the last mile, the existing 1550nm, 1310nm, and 850nm quartz optical fiber signals must be converted into 650nm plastic optical fiber signals, and then further converted to the user terminal, due to the different user terminals Arrangement position, signal attenuation during transmission, in the plastic optical fiber system integrated all-optical network, 650nm optical relay is required because the distance is too long, without optical relay, the all-optical network cannot be connected
