MTP optical fiber coupler / MPO fiber adapter is the connector used to connect the MPO female trunk cable and MPO male trunk cable. It is also designed to connect the MPO female trunk cable with the MPO male module (MPO male to LC module).
This high-performance adapter is fully compatible with MPO-8, MPO-12, MPO-16, MPO-24, MPO-32, and MPO-48 connectors, making it an essential component for MPO high-density patch panels and FTTA multi-function boxes.
Key Coupling Types
❖
Opposed type (Key Up to Key Down): The top hook on one side flips on the other side. This is standard Type A.
❖
Aligned type (Key Up to Key Up): The top hook stays on top on both sides. This is used in Type B networks.
Additionally, the MTP optical fiber coupler / MPO fiber adapter is designed with a flange, allowing for more secure and stable fixation inside the patch panel plate.

Frequently Asked Questions (FAQ)
Q1: What is the primary function of an MTP/MPO optical fiber coupler?
A1: It is used to connect an MPO female trunk cable to an MPO male trunk cable, or to connect an MPO female trunk cable to an MPO male module (such as an MPO male to LC module).
Q2: What is the difference between Opposed and Aligned key configuration?
A2: Opposed type (Key Up to Key Down) features a top hook on one side that flips on the other, which is standard for Type A. Aligned type (Key Up to Key Up) keeps the top hook on top on both sides, which is commonly used in Type B networks.
Q3: Which fiber counts are compatible with this adapter?
A3: The adapter is fully compatible with MPO-8, MPO-12, MPO-16, MPO-24, MPO-32, and MPO-48 connectors.
Q4: Does this MPO/MTP coupler support single-mode and multimode fibers?
A4: Yes, it supports both Single mode (UPC/APC) and Multimode (including OM3 Aqua and OM4 Violet options) fiber types.
Q5: What are the temperature ranges for operating and storing this adapter?
A5: The operating temperature range is -20°C to 70°C, and the storage temperature range is -40°C to 85°C.
Q6: What makes the one-piece coupler design beneficial?
A6: The one-piece design maximizes the coupling strength of the adapter while reducing the generation of debris during connection, ensuring high reliability.
