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

The 4-Port Fiber MST Terminal with Built-In PLC Splitter is designed for rapid FTTH deployment in outdoor environments. The compact enclosure integrates a factory-installed 1×4 PLC splitter, eliminating the need for traditional stub cables. The stubless, tail-free design allows technicians to connect hardened drop cables directly to the terminal, reducing installation time and labor cost.

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.

What Is an 4-Port MST Terminal with Built-In PLC Splitter?

The terminal is fully H Connector compatible, supporting hardened SC/APC connectors for fast plug-and-play installation. With an IP68 waterproof rating, the enclosure provides reliable protection against UV exposure, rain, salt spray, dust, freezing temperatures, and chemical corrosion. The housing is molded from high-strength thermoplastic to ensure long-term durability in harsh environments.

Multiple mounting options are available, including pole, wall, pedestal, and aerial strand mounting. Each terminal is factory-sealed, pressure tested, and inspected to ensure low insertion loss, consistent optical performance, and long-term network stability. This solution is ideal for ISPs and network operators requiring a robust, maintenance-free access point for last-mile fiber distribution.
