Description
The SOLiD SMDR-NH124-BIU is a high-performance Type B R-Optic module designed for use in the BIU (Base Station Interface Unit) chassis. Supporting multi-band DAS deployments, this module enables efficient downlink and uplink conversion between digital and analog signals. It provides optical connectivity between BIU and OEU/REU units through dual LC optical ports. The module supports up to 4 service bands, making it ideal for indoor cellular coverage solutions across DAS environments including LTE, 5G, and 4G systems.
This plug-in card fits directly into the BIU chassis alongside other critical system cards such as the MCPU and PSDU. It is engineered for low power consumption, modularity, and reliable high-speed optical transmission in distributed wireless infrastructure.
