MST – Splitter Tail

Product Overview

NetSource’s MST Fiber Terminals with Splitter Tails, designed and manufactured in the U.S., provide a durable and efficient solution for fiber-to-the-x (FTTx) network deployments. Engineered to withstand harsh outdoor conditions, these IP68-rated terminals ensure long-term reliability with robust protection against dust and water ingress. Each terminal is preconfigured with factory-installed splitters and terminated with OptiTap®-style single-fiber connectors, simplifying drop installations and reducing field labor.  By integrating splitter tails, these MSTs eliminate the need for separate splitter enclosures, reducing installation complexity and field splicing. This design enables incremental network expansion, making it an ideal solution for both rural broadband and high-density deployments. By efficiently distributing fiber, it helps  Available in 4-port (1×4 splitter), 8-port (1×8 splitter), and 12-port (1×12 splitter) configurations, these MSTs optimize fiber utilization by reducing the number of feeder fibers needed. This results in lower capital expenditures and faster customer activation, supporting scalable and cost-effective FTTx network expansion.
