Embodiment 1

[0070] Example as image 3 As shown, the optical signal 11 output by the equipment transmitter is sent to the optical power amplifier 5 to be amplified and then becomes a line output optical signal 12, which is sent to the optical fiber transmission line; the opposite line input optical signal 13 transmitted by the optical fiber line is passed through the optical preamplifier 6 After being amplified, the device receives the optical signal 14 and sends it to the device receiver; the state of the line input optical signal 13 monitored by the optical preamplifier 6 is sent to the machine disk controller 3, and then the optical power amplifier 5 is controlled after analysis and processing. working status.

Embodiment 2

[0071] Example two such as Figure 4 As shown, the optical signal 11 output by the equipment transmitter is sent to the optical power amplifier 5 to amplify and become a line output optical signal 12 and then sent to the optical fiber transmission line; the opposite line input optical signal 13 transmitted by the optical fiber line is divided by the optical coupler 7 A part of the light is sent to the optical power detector 8 to monitor the input optical signal, while the main optical signal is sent to the equipment receiver as the equipment receiving optical signal 14; the state of the line input optical signal monitored by the optical power detector 8 is sent to The disk controller 3 controls the working state of the optical power amplifier 5 after analysis and processing.

Embodiment 3

[0072] Embodiment three such as Figure 5 As shown, the optical signal 11 output by the transmitter of the device is sent to the optical power amplifier 5 to be amplified to become a line output optical signal 12 and then sent to the optical fiber transmission line; the input optical signal 13 of the opposite end line transmitted by the optical fiber line is directly sent to the optical receiver of the device The machine 9 performs optical signal reception; the equipment optical receiver 9 sends the monitored state of the line input optical signal to the machine disk controller 3 while receiving the optical signal, and then controls the working state of the optical power amplifier 5 after analysis and processing.

Abstract

This invention relates to an eye protection device and a method for a large power signal transmission system, in which, an optical power detector PD sends the monitored signal state of input light to a BCT to control an optical control unit OCU to regulate the output optical signals to a related data state and communicate with a host device management computer, which does not use any additional optical wave channels to monitor the broken and resuming of optical transmission lines and enter into and retreat from the eye protection state.

Description

technical field [0001] The invention relates to the technical field of long-distance optical communication, in particular to SDH, IP and WDM optical transmission systems that require high-power optical output. Background technique [0002] With the extension of optical communication transmission distance, it is more and more common to use high-power optical transmission devices and optical power amplifiers in optical communication systems, and the signal optical power also tends to increase rapidly. However, in normal times, this kind of high-power optical signal that can be well restrained in the core layer of the communication fiber will leak into the free space once the fiber breaks, which may cause serious damage to the personnel who come into contact with the fiber section. , especially the eye damage caused by the repair personnel of optical fiber lines. Due to the potential safety hazards of high-power optical signals, the IEC has clear regulations on the upper limit...
