Attach a ground wire from one of the threaded studs (A) at the bottom of the housing, to the mounting plate (B). Abstract: System grounding considerations affect many aspects of an electrical system. Primary distribution systems consist of feeders that deliver power from distribution substations to distribution transformers.

This forces distribution transformers to be located within several hundred feet of each customer, but eliminates the reliability concerns associated with T-splices that are required to connect underground servic.

Capable of serving up to 4/8 subscribers, it functions as an essential termination point in FTTx communication networks, accommodating fiber splicing, splitting, and distribution effectively. A key challenge is determining how many users a single OLT port can support, which is defined by the split ratio. Traditional GPON networks often employ 1:32 or 1:64 splits, while XGS-PON allows higher ratios such as 1:128. By dividing a single optical signal from a central Optical Line Terminal (OLT) into multiple outputs for Optical Network Terminals (ONTs) at users' homes, splitters eliminate the need for dedicated fibers to each residence—slashing infrastructure costs while scaling network reach. It is used as a termination point for the power cable for connection with the drop cable in the FTTx network system.
