TheMPO (Multi-fiber Push On)connector is designed to handle multiple fiber strands in a single connector, and it is commonly used with high-density transceivers likeQSFP (Quad Small Form-factor Pluggable).
* QSFPcan support up to four channels (hence "quad"), andMPOconnectors can interface multiple fibers (e.g., 8, 12, 24), making them ideal for40Gbps or 100Gbpsdeployments.
* RJ45 (A) is used for Ethernet over copper.
* ST (B) and LC (C) are single-fiber connectors - they don't support the multi-fiber needs of QSFP setups.
#Therefore,MPOis the correct connector type for this use case.
