Definitions
- a first wavelength division multiplexing filter configured to perform splitting and uplink light coupling of downlink light of different PON systems: the uplink/downlink light of the first PON system is transmitted through the first optical channel, and is first long Enlarging from the amplification box, the upper/downward light of the second PON system is transmitted through the second optical channel and amplified by the second long-distance amplification box; and the upstream light transmitted by the first optical channel and the second optical channel passes through the first a wavelength division multiplexing filter is coupled into the backbone fiber;
- the downlink light of the first UI system is sent by the OLT of the first UI system, reaches the C interface of the first wavelength division multiplexing filter via the trunk fiber, and then filters from the first wavelength division multiplexing filter.
- the R interface of the device is output to the first optical channel, and is output to the R interface of the second wavelength division multiplexing filter via a first long-distance amplification box corresponding to the first UI system, and then from the second
- the C interface of the wavelength division multiplexing filter is output to the trunk fiber, and finally reaches the ONU via the splitter branch fiber;
- a long-distance box processing method for uplink and downlink light comprising:
