Overview of 16 Port MST Multiport Service Terminal

The 16 Port MST Multiport Service Terminal (MST Box) from Spring Optical is a ruggedized, IP68-rated hardened fiber distribution terminal designed for rapid FTTH deployment in outdoor environments. As part of the FastConnect architecture, the MST enables plug-and-play drop cable installation without opening the closure, dramatically reducing installation labor, minimizing splicing work, and accelerating time-to-service for operators.

Engineered for aerial, pole-mounted, wall-mounted, and overground FTTH distribution, the MST terminal supports 16 hardened FastConnect drop cable ports and an additional express port. Its compact, reinforced PC+ABS enclosure ensures long-term durability against UV exposure, humidity, vibration, salt fog, and harsh outdoor conditions.

With compatibility across OptiTap, Huawei FastConnect, ODVA, ODC, MINI-SC, FullAXS, and other industry-standard hardened interfaces, the Spring Optical MST delivers maximum interoperability and flexibility for global telecom operators, ISPs, and network integrators.

FAQ

Q1. What is the difference between an MST and a standard FAT box?

MST uses pre-terminated hardened connectors, enabling plug-and-play installation. FAT requires splicing.

Q2. Can I customize port quantity or adapter types?

Yes. Spring Optical provides full OEM/ODM service including 4/8/12/16/24-port customization.

Q3. Does it support mixed adapters (OptiTap + Mini-SC)?

Yes, mixed interfaces can be provided upon request.

Q4. Does the box need to be opened during installation?

No. The FastConnect design avoids opening the enclosure, protecting internal fibers.

Q5. Is it suitable for underground installation?

Yes. The IP68 sealing design supports overground and shallow burial environments.
