Indoor Fiber Termination Box vs Outdoor Box: Which Is Right for Your FTTH Project?

For FTTH planners, installers, telecom operators and developers, choosing the right indoor/outdoor fiber termination box is foundational to network stability, durability, efficiency and scalability. As a leading global FTTH solution provider, JERA LINE offers high-performance, internationally compliant boxes that adapt to diverse environments, support 10G PON and ensure low-loss transmission for residential, commercial, industrial and rural use. Ideal for new builds or upgrades, they solve environmental adaptability, durability and integration issues, delivering future-proof, reliable fiber distribution core equipment.

What Are JERA LINE Indoor & Outdoor Fiber Termination Boxes?

JERA LINE indoor and outdoor fiber termination boxes are core ODN nodes for FTTH, FTTB, FTTC and FTTO networks, connecting backbone fiber and end-user cables. They provide stable fiber splicing, distribution and protection, ensuring low-loss high-speed transmission.

Compliant with global standards, indoor boxes fit mild indoor environments, while outdoor ones are rugged for harsh outdoor conditions. Combined with JERA LINE fiber sockets and FDB, they form a complete integrated fiber communication system.

Core Differences Between JERA LINE Indoor & Outdoor Fiber Termination Boxes

JERA LINE indoor and outdoor fiber termination boxes are optimized for different scenarios, with clear differences in protection, materials, structure and environmental adaptability:

1. Protection Level

Indoor: IP30/IP40, basic dustproof and anti-touch, suitable for stable indoor environments.

Outdoor: IP54/IP65, professional waterproof, dustproof and anti-condensation, for harsh outdoor conditions.

2. Material & Durability

Indoor: High-grade fire-retardant ABS/PVC, lightweight and easy to install.

Outdoor: Reinforced plastic or metal alloy, UV-resistant, anti-aging, wide-temperature (-40℃ to +60℃) and maintenance-free.

3. Structural Design

Indoor: Compact, with easy-operation fusion trays, 4–48 core flexible configuration, quick installation.

Outdoor: Robust and sealed, with anti-theft lock, independent drainage, suitable for pole/wall/ground mounting.

4. Environmental Adaptability

Indoor: -5℃ to +40℃, humidity ≤85%, for mild indoor spaces.

Outdoor: -40℃ to +60℃, humidity ≤95%, anti-corrosion and UV-resistant, for various harsh outdoor regions.

How to Choose: JERA LINE Indoor or Outdoor Fiber Termination Box for Your FTTH Project?

JERA LINE indoor or outdoor fiber termination boxes are selected based on FTTH project scenario, installation site, fiber capacity and long-term network planning. Here is the concise selection guide:

Choose JERA LINE Indoor Fiber Termination Box If:

• Your node is in closed, stable indoor spaces (home info boxes, office weak current wells, equipment rooms, etc.)
• You need space-saving, easy-to-maintain equipment for indoor FTTH/FTTO
• Fiber capacity is small to medium (4–24 cores)

Typical Applications:

High-rise residential wiring, office FTTO, commercial/school/hospital indoor optical communication systems.

Choose JERA LINE Outdoor Fiber Termination Box If:
