In today’s fast-paced fiber optic infrastructure landscape, telecom operators and system integrators are under increasing pressure to deploy networks faster, more reliably, and with lower cost. Every deployment scenario—whether it’s rural broadband expansion or dense urban fiber rollouts—comes with its own challenges. That’s where a custom Fiber Optic MST Box (Multi-port Service Terminal) becomes an essential component of scalable and efficient FTTx and OSP network architectures.
This guide will explore the advantages of customized MST Enclosures, outline the available configurations, and explain how tailored MST solutions improve operational efficiency and network performance.
What Is a Fiber Optic MST Box?
A Fiber Optic MST Box, or Terminal de Servicio Multipuerto, is a weatherproof outdoor fiber distribution enclosure that connects feeder cables to drop cables in FTTx (Fiber to the x) networks. These plug-and-play boxes are pre-terminated and pre-tested to minimize on-site splicing and reduce installation complexity.
Standard Features of Fiber Optic MST Box:
- IP68 Rated: Fully dustproof and waterproof for harsh environments
- Multiple Port Options: Common configurations include 4, 6, 8, 12, and 16 ports
- Pre-terminated Connectors: SC/APC, SC/UPC, and other options available
- Mounting Flexibility: Supports pole, strand, pedestal, and handhole mounting
- Versatile Applications: Suitable for both aerial and underground deployments
- Compatibilidad del conector: Hardened or standard SC connectors
Why Customize a Fiber Optic MST Box?
Off-the-shelf fiber terminal boxes often lack the flexibility to meet the unique demands of specific deployment environments. A custom MST box allows operators to specify key design elements—such as port types, cable types, and materials—tailored to their network and environmental conditions.
Key Benefits of Custom MST Box Solutions:
- Customizable port counts and connector types (SC, LC, MPO, etc.)
- Choice of enclosure material: corrosion-resistant, UV-stable, or flame-retardant
- Drop cables pre-terminated to exact length with optional pulling eyes
- Support for multiple mounting methods
- Branding and asset tracking options: laser marking, QR codes, OEM labels
- Long-term durability for outdoor, marine, or high-humidity installations
Types of Fiber Optic MST Box
At bativ, we provide a full range of MST enclosures engineered to suit a variety of use cases. Below are six of the most common MST box types:
1. Standard MST Box
- Use Case: Traditional FTTH or ODN deployments
- Ports: 4, 6, 8, 12, 16
- Connectors: SC/APC, SC/UPC
- A general-purpose fiber terminal with pre-connectorized outputs for rapid installation in last-mile deployments.
2. MST Box with Built-In Splitters
- Use Case: PON (Passive Optical Network)
- Splitters: 1×4, 1×8, or custom
- Integrates PLC splitters to divide one feeder into multiple subscriber drops—ideal for GPON or XGS-PON rollouts.
3. Hybrid Power-Fiber MST Box
- Use Case: FTTA, PoE, or remote powering
- Característica: Combines fiber optic and DC power cables
- Simplifies the deployment of powered devices such as small cells and surveillance systems.
4. MPO/MTP MST Box
- Use Case: Data centers, 5G fronthaul/backhaul
- Conector: MPO/MTP
- High-density terminal supporting multi-fiber connectivity for fast plug-and-play deployment.
5. MST with Toneable Drop Cable
- Use Case: OSP cable tracing in underground or hybrid builds
- Característica: Toneable cable for field identification
- Facilitates easy maintenance using standard tone-and-probe tools.
6. Specialized MST Box with Custom Drop Cables
- Use Case: Tight-space or specialized cable requirements
- Options: Flat dielectric, armored, or custom-jacketed cables
- Pre-terminated jumpers for compact and secure installations in constrained spaces.
Application Scenarios for MST Box
FTTH Deployments
MST Boxes can replace traditional FDH (Fiber Distribution Hubs) or ONUs by integrating splitter modules directly into the enclosure. Supporting up to 24 protection sleeves and 2–4 1×8 PLC splitters, pre-connectorized MST Boxes with IP67-rated connectors can serve up to 48 fibers. Their simplified design allows non-expert technicians to install them with 40% higher efficiency and reduced signal loss.
FTTA Deployments
Fiber to the Antenna (FTTA) systems traditionally connect each Remote Radio Unit (RRU) to the BBU with separate cables. MST Boxes consolidate multiple RRU connections into a single hybrid trunk, dramatically reducing cabling and speeding up deployment. Built-in power connectors eliminate the need for separate power lines.
Trunk Cable Management
Frequent fusion splicing in trunk cables requires robust protection. MST Boxes are equipped with anti-torsion cable glands and internal strain relief features. These boxes support up to 24 splices and two PLC splitters, accommodating cable diameters from 5mm to 14mm. Mechanical stability ensures durability under pulling forces up to 1200N.
