It is the DC distribution unit or device. It serves for distributing the DC power needed for different power needed devices like RRU, EMUB, BBU and many more. DCDU-12B of Huawei consist of two input terminal blocks and 10 different ports for output. Each port or certain port is assign for its maximum output fuse current.

Thanks for posting a nice blog on power distribution unit
Great initiative upgrading this article and moving it to your new website. The explanation of the Huawei DCDU-12B is clear and practical, especially the way you’ve covered input capacity, fused outputs, and operating conditions. From real site experience, proper power distribution along with Telecom grounding and bonding hardware plays a critical role in protecting RRUs, BBUs, and other DC-powered equipment. Clearly labeled fused outputs also make troubleshooting and maintenance much easier during live operations. The compact design and wide temperature tolerance are major advantages for outdoor BTS and remote telecom sites. Looking forward to the updated DCDU functions details on your new platform these insights are genuinely valuable for field engineers and technicians
