12-Wavelength Active Fiber Capacity-Expansion Equipment
As wireless networks expand, large-capacity distributed base stations move closer to users for deep coverage. Traditional direct-fiber BBU-RRU fronthaul consumes substantial fiber resources and is difficult to expand. Huixinte's compact 1U WDM equipment addresses cable-resource shortages in C-RAN BBU-RRU extended transmission, meeting operators' requirements for deeper coverage and flexible expansion.
