Fiber MST Terminal 4-Port with Built-In PLC Splitter, Stub Tail

Fiber MST Terminal 4-Port with Built-In PLC Splitter and Stub Tail is a compact and rugged fiber access terminal designed for FTTH distribution networks requiring lower port density and flexible deployment.

Features

Low Loss &High Reflection

MST terminals are fully assembled and factory-sealed.All optical performance specifications comply with GR-771-Core,GR-1209-Core ensuring low insertion loss and high return loss.

IP68 rating

Each MST fiber optic terminal undergoes a strict air-tightness and pressure test to verify IP68 protection for long-term outdoor reliability.

Easy installation

To adapt to diverse installation scenarios, MST terminals support three mounting methods: aerial, wall-mounted, and pole-mounted.
This design enables fast and flexible field deployment.

An Overview of 4 Port MST Terminals with Built In PLC Splitter and Stub Tail

This 4-port MST terminal integrates a factory-installed PLC splitter inside the enclosure, enabling efficient fiber distribution from a single feeder fiber to multiple drop connections. The stub tail design allows direct splicing to the feeder cable, reducing installation time and minimizing on-site fiber management complexity.

Fully H Connector compatible, the hardened ports support plug-and-play drop cable connections, making it ideal for outdoor installations such as poles, walls, or pedestals. The enclosure is IP68 rated, providing reliable protection against water, dust, and harsh environmental conditions commonly found in access networks.

Compared with higher-port-count MSTs, the 4-port configuration is especially suitable for low-density FTTH builds, rural broadband deployments, and network extensions, where fewer subscribers are served from a single distribution point while maintaining high reliability and scalability.
