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.
