RRUS¶

The RRU (remote Radio Unit) is basically an outdoor version of the classic indoor radio units like the RUS.

This provides the advantage that it can be mounted on the top (or at half height) of the tower, reducing the length of the lossy coaxial cables, and extending the length of the front-haul interface.

The front-haul distance is limited by signal propagation speeds and is in the magnitude of 40km between RRUS and digital unit.

Power Supply¶

all RRUS are powered by -48 V DC (-38.0 to -58.5V). There are optional 90-275V AC PSU modules ("PSU AC") that can be mounted on the RRU back.

the connector on RRUS12 is a Amphenol C10-730511-Z2S or similar enough (e.g. https://www.alibaba.com/product-detail/Amphe-OBTS-plug-10-730511-Z2SM_62570921262.html)
