MT stands for mechanical transfer. MT ferrule is a type of ferrule used in high-density optical fiber connectors, such as MPO connector (Multi-fiber Push On) and MTP (Multifiber Termination Push-on). 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.

FSG provides MT/MPO ferrules from 12, 16, 24, 32, 36 to 48cores, and custom solutions available.

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

MT ferrule provides 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.

MT ferrules are widely applied in multiple optical connectors like MPO/MTP, QSFP+ transceivers, active optical cables (AOC cable), mpo cables, and also suitable for custom designed passive or active fiber coupling packages.

Guide Pin (Male Pin)

Guide pin (also known as male pin) plays a crucial role in ensuring precise alignment and secure mating between MT ferrule connectors. It’s also referred to as male pins due to their 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.
