RRU optical module transmission and reception abnormality
Use an optical power meter to check whether the transmit optical power of the optical module is normal. After combining the RRU log analysis and the alarm of the optical module, the radio frequency maintenance link is triggered by the power-off of the RRU board, as shown in the following screenshot. The cause of the RRU startup alarm record is 00 00, which represents the board is powered off. Customers in the use of optical modules will more or less encounter a variety of failure problems, such as optical module model selection is correct, the use of jumper is correct and some common problems, customers have the ability to judge and have a clear solution, but for some of the use of. This document describes routine maintenance procedures for an RRU3252/RRU3256 (referred to as RRU in this document), such as equipment preventive maintenance and power-on and power-off operations.

Rru side lighting module
The RRU-X-UNV includes dual relays and is suitable for simultaneously bypassing a line voltage relay/switch and breaking the 0-10V line for full brightness operation. Its small size is ideal for fixture mounting alongside wireless lighting controls. The RRU consists of the following function modules: high-speed interface unit, signal processing unit, power amplifier, duplexer, extension interfaces, and power module. This allows the override of outputs during loss of normal (grid) power to allow an alternate power source to drive the lighting loads (Once the RRU senses the normal power returning, the control panel will return to the normal programmed operating mode). Turn to TE Connectivity (TE) for innovative and proven, reliable solutions including ruggedized connector sealing systems, RF, antenna design, and high-performance power and signal products.

Distance between 380V power cables and fiber optic cables
The National Electrical Code establishes specific minimum distances when communications cables must run near power and light circuits. This practice is mandatory for two distinct reasons: ensuring the safety of the structure and its occupants, and preserving the integrity of sensitive data. by Jeanna Deese and Chris Rivas Power over Ethernet—it may be an old concept, but new applications continue to be identified that are redefining. Let's dive deeper together! What Factors affect the fiber optic cable distance?TECHNICAL GUIDELINE July 30, 2020 TG030 Rev.
