a fan assembly that is independent of the at least one remote radio unit, wherein the fan assembly is arranged opposite to one side of the remote radio main body with the heat-dissipation fins, and wherein the fan assembly is disposed side by side with the at least one remote radio unit; and
an air duct that is disposed between the fan assembly and the remote radio unit, wherein an airflow passes, from the fan assembly, through the air duct, and arrives at the at least one remote radio unit to dissipate heat of the at least one remote radio unit.

2. The communications product according to claim 1 , wherein the communications product further comprises a mounting assembly, wherein the mounting assembly is located at a side of the back end plate of the remote radio unit, wherein the mounting assembly comprises:
a securing part, wherein the securing part is securely connected to the remote radio unit and the fan assembly; and
a ventilation part securely connected to the securing part, wherein the air duct is formed inside the ventilation part, wherein the ventilation part comprises at least two openings, wherein the at least two openings correspond one-to-one to the at least one remote radio unit and the fan assembly, and wherein the at least two openings are respectively connected to a first air vent and a second air vent, wherein the first air vent is disposed on the back end plate of the remote radio unit, and wherein the second air vent is disposed on a surface which faces the mounting assembly of the fan assembly.

3. The communications product according to claim 2 , wherein the fan assembly comprises:
a front end surface; and
a back end surface, wherein the second air vent is disposed on the back end surface, wherein multiple ventilation openings are distributed on the front end surface, and wherein the airflow forms convection inside the fan assembly through the ventilation openings and the second air vent.

4. The communications product according to claim 3 , wherein the front end surface is coplanar with the front end plate of the remote radio unit, and wherein the back end surface is coplanar with the back end plate of the remote radio unit.

5. The communications product according to claim 2 , wherein the ventilation part is located below the securing part or above the securing part.

6. The communications product according to claim 5 , wherein the securing part comprises at least two sub-securing parts that are mutually spliced into a single-row structure, wherein the ventilation part comprises at least two sub-ventilation parts that are mutually spliced into a single-row structure, wherein the at least two sub-securing parts and the at least two sub-ventilation parts correspond one-to-one to each other to jointly form a double-row structure, wherein the at least two sub-ventilation parts internally communicate with each other, and wherein the at least two openings are respectively disposed on the at least two sub-ventilation parts.

7. The communications product according to claim 2 , wherein the multiple heat-dissipation fins are distributed on two sides of the remote radio main body, and wherein a connection of the first air vent and the at least two openings makes the air duct communicate with the multiple heat-dissipation fins on the two sides of the remote radio main body.

8. The communications product according to claim 2 , wherein there are multiple remote radio units, and wherein the fan assembly is located on a side of the multiple remote radio units or located between two of the multiple remote radio units.

9. The communications product according to claim 2 , wherein the remote radio unit and the fan assembly are superimposed over each other to form two rows of communications components, wherein the mounting assembly is located between the two rows of communications components, and wherein the two rows of communications components share the air duct.

10. The communications product according to claim 9 , wherein the back end plate of the remote radio unit in one row of the two rows of communications components faces the back end plate of the remote radio unit in the other row of the two rows of communications components.

11.
