Problems solved by technology

However, from the actual situation, for areas without reserved communication pipelines, the investment cost of new optical fiber communication facilities is relatively high, and construction is difficult; for areas with reserved communication pipelines, due to ground subsidence and other pipeline construction, 20% -30% of the pipes are blocked, resulting in the inability of optical fibers to pass through
For these reasons, the cost of networking by using optical fiber communication alone is relatively high

Embodiment Construction

[0014] The present invention will be further described below in conjunction with accompanying drawing:

[0015] Such as figure 1 , 2 As shown, the present invention is composed of an optical fiber communication system, an optical network unit device 1 , a head-end device 2 , a relay device 3 , a terminal device 4 , and a coupler 10 .

[0016] The optical network unit device is used to receive the optical signal sent by the optical fiber communication system, convert the optical signal into a digital signal, and then send the digital signal. Among them, the optical network unit device is ONU (OpticalNetworkUnit); the optical signal sent by the optical fiber communication system can be the downlink communication data in the form of light waves sent by the OLT (optical line terminal) in broadcast mode. 3 Standard digital signals, used to represent downlink communication data.

[0017] The head-end device is connected to the optical network unit device through a network cable t...
