MT Ferrule
for MPO Connector & 100G/400G Optical Transceiver Module

MT stands for mechanical transfer. MT ferrule is a multi-core polyphenylene sulfide (PPS) ferrule with a square end-face of 6.4×2.5 mm and 0.25mm pitch. The alignment mechanism consists of two stainless steel guide pins that fit into precisely molded alignment holes.

MT ferrules are widely applied in multiple optical connectors like MPO/MTP, QSFP+ transceivers, active optical cables (AOC cable), and also suitable for custom designed passive or active fiber coupling packages.
Fiber is secured to the ferrules with an optical connector grade thermal cure epoxy and can be polished with a variety of commercially available batch connector polishing machines.
FSG’s highly stable, PPS material MPO ferrule allows preparation of fiber tip protrusion with reduced polishing time and force resulting in superior end-face geometry control. FSG MT ferrule are available from 2, 4, 8, 12, 16, 24, 32 & 48cores, standard loss and Elite low loss type, of them 12 and 24 fiber MT ferrules are the most commonly used types, particularly for MPO connectors and MPO cables.

MT Ferrule is widely used in high density fiber networks as a key component.


Key component in MPO
connector
MT ferrule is a key component in MPO connector. It mates with another MT ferrule, and the connection quality decides the optical performances insertion loss and return loss. The ferrule paly a key role in the connection.

MT- Fiber Array Assembly
MT to Fiber Array assembly can be used inside of an optical device package as light output /input which has MPO connector to system board instead of using long fiber and rubber boots outside the device. Therefore it can reduce the package size and fiber routing space.

Features
- From Single Channel to 64Channels
- High Precise Fiber Core-to-Core Accuracy High Precise Polishing Angle
- Low Insertion Loss and High Reliability
- Telcordia GR-1209 & GR-1221-CORE Compliant
MT Fiber Applications
MT Ferrule is widely used in high density fiber networks as a key component. Besides MPO/MTP connectors, the ferrule is assembled with MT/Fiber Array/PM Panda Fiber/Ceramic Ferrules as devices used in modules and optical transceivers. Recent years, MPO ferrule is also used in HDMI 2.1 cable for 8K HD televersion.
