MT Ferrules

MT, standing for Mechanical Transfer, ferrules are a type of ferrule used in high-density optical fiber connectors, such as MPO connectors (Multi-fiber Push On) and MTP (Multifiber Termination Push-on).

A standard MT ferrule has a square end-face of 6.4×2.5 mm that holds and aligns multiple fibers in a compact form factor. It provides improved optical performance by precisely aligning the fibers and minimizing the loss of light between them.


OFP provides MT/MPO ferrules for 12, 16, 24, 32, to 48 cores, as well as multiple custom solutions.

MT ferrules are a key component in high-density fiber optic connectivity and are commonly used in data centers, telecommunications networks, and other high-bandwidth applications.


MT ferrules provide a cost-effective solution for high-density fiber optic connectivity, enabling higher fiber count and increased data transmission capacity.


The use of MT ferrules helps reduce the amount of physical space needed for fiber optic cabling, making it ideal for applications with limited space.

Guide Pin (Male Pin)


A guide pin (also known as a male pin) plays a crucial role in ensuring precise alignment and secure mating between MT ferrule connectors. It’s also referred to as a male pin due to its protruding structure that fits into corresponding holes on the opposing connector. Guide pins are primarily utilized in connectors like MPO (Multi-Fiber Push-On), where multiple fibers need to be precisely aligned and mated simultaneously. It helps to guide the connectors into proper alignment during the mating process. This alignment is crucial for maintaining low insertion loss and high signal integrity in fiber optic systems. There are different shape of pin clamps to fit for varying devices requirements.

Ferrule and Guide Pin Inspection


Yagishita Giken Equipment

For our high precision MT Ferrule inspection, we use Yagishita Giken equipment to measure the MT ferrule x and y axis, as well as the fiber holes and male pin holes.


Union Tool Digital Passameter DS-2000

To ensure excellent quality of the guide pins, we use a Union Tool Digital Passameter DS-2000. It allows a .01 um resolution, with the use of a contact probe, for male pin & ferrule mold accessories.
