The terms MPO/MTP trunk cables, MPO/MTP harness cables, MPO/MTP breakout cables, and MPO/MTP fanout cables all refer to fiber optic cables with MPO/MTP connectors, but they are designed for different purposes and configurations. Here's a detailed breakdown of their differences:
Design: The MPO/MTP trunk cable is a high-density cable that uses MPO or MTP connectors on both ends, typically with 12, 24, or 48 fibers. The cable consists of a single cable with MPO/MTP connectors at each end, and it does not have any breakout or fanned-out structure.
Use Case: Ideal for direct connections between high-density equipment (e.g., switches, patch panels, or servers) where you need a large number of fibers in a simple, high-capacity connection.
Key Feature: No termination into individual connectors. It is used for straightforward, high-density connections between MPO ports or devices.
Example: A 12-fiber MPO/MTP connector on each end of the cable, used to connect two MPO ports directly.
Design: The MPO/MTP harness cable has a single MPO/MTP connector at one end and multiple MPO/MTP connectors at the other end. It allows one high-density MPO port to connect to multiple other MPO ports, with the individual branches ending in MPO connectors.
Use Case: Ideal for connecting a single MPO port to multiple MPO ports, commonly used in data centers to connect a single switch or device to multiple other devices or patch panels.
Key Feature: It "branches out" from one MPO connector into multiple MPO connectors. It's like a "splitter" for MPO connections, but still uses MPO connectors throughout.
Example: A cable with a single 12-fiber MPO/MTP connector on one end, splitting into three 8-fiber MPO connectors on the other end.
Design: The MPO/MTP breakout cable has a single MPO/MTP connector at one end and individual fiber connectors (typically LC, SC, or ST) at the other end. The fibers break out from the MPO connector and terminate into separate, individual connectors.
Use Case: Used when you need to connect a single MPO port to individual devices that require different connectors (e.g., LC or SC). This is common for server or switch connections where devices have single-fiber connections (LC, SC, etc.).
Key Feature: Breaks out into individual fiber connectors at the far end, often with fiber segments in separate jackets. It is a solution for transitioning from high-density MPO to single-fiber terminations.
Example: A 12-fiber MPO/MTP connector at one end, with 12 individual LC connectors at the other end, where each LC connector is used to connect to individual devices.
Design: The MPO/MTP fanout cable is very similar to the breakout cable, but it typically has a more structured, "fanned-out" design, where the fibers from the MPO/MTP connector are arranged neatly into individual fiber connectors (usually LC connectors) in a specific pattern.
Use Case: Often used in high-density environments (like data centers), where you need to convert a single MPO connector to several individual fiber connections in a more organized and space-efficient manner.
Key Feature: The fibers fan out neatly from a central MPO/MTP connector to multiple individual connectors, typically with better cable management for high-density applications. It's often used in scenarios where the cable is installed in trays or racks.
Example: A 12-fiber MPO/MTP connector at one end, with 12 LC connectors at the other end, organized in a structured fanout design, often with a single sheath or jacket for easier management.

MPO/MTP Trunk Cable: High-density, direct MPO-to-MPO connection with no breakout.
MPO/MTP Harness Cable: One MPO connector to multiple MPO connectors, used for distributing connections to multiple devices.
MPO/MTP Breakout Cable: One MPO connector that "breaks out" into individual fiber connectors (e.g., LC, SC), used for connecting to devices with single-fiber ports.
MPO/MTP Fanout Cable: Similar to breakout cables but with a more structured, fanned-out design, often used in high-density environments for more organized cable management.
Each cable type is tailored to a specific application, with trunk cables being used for simple, high-capacity connections, harness cables for branching out to multiple MPO ports, breakout cables for connecting to individual devices, and fanout cables offering more organized management of the individual fiber terminations.
