The Fiber Optic Terminal Box 3 (HTB3) is a compact indoor FTTH termination box designed to manage and terminate up to 2 optical fibers with flexible adaptor and splice options.

Overview

The HTB3, also known as an Indoor Optical Outlet (IOO) or Fiber Wall Outlet (FWO), serves as the indoor endpoint of a Fiber to the Home (FTTH) network, terminating the Optical Distribution Network (ODN) at the user's premises. It provides a secure and organized interface for connecting fiber optic cables to pigtails or other network equipment, ensuring reliable data transmission and network connectivity .

Key Features

• Compact Design: Measures 86 mm x 86 mm x 26 mm, compatible with standard in-house electrical outlet boards .
• Flexible Cable Entry: Allows fiber input from all sides—top, bottom, left, right, and back—facilitating versatile installation .
• Fiber Management: Supports G.657 fiber bend radius, includes storage for unused adaptor dust caps and pigtail dust caps, and allows splicing and storing drop cables .
• Adaptability: Configurable bill of materials and flexible adaptor positions accommodate varying cable boot lengths .
• Durability: Made from ABS housing, dust-proof, and suitable for indoor deployment .

Applications

• Single Dwelling Units (SDU) and Multi-Dwelling Units (MDU): Ideal for residential FTTH installations, providing a neat and secure termination point for optical fibers .
• Network Termination: Connects fiber optic cables to optical switches, patch panels, or other network devices, enabling high-speed broadband and data services .
• Future-Proofing: Compatible with various FTTH topologies and can be used in conjunction with splitters, patch, and splice options for network expansion .

Installation and Maintenance

• Wall Mountable: Easy to install on walls, with a small footprint that blends with existing electrical outlets .
• Cable Management: Designed to maintain proper bend radius and strain relief, reducing signal loss and ensuring long-term network reliability .
• Access Protection: Dust-proof design and organized internal layout protect fiber connections from contamination and physical damage . The HTB3 is a reliable, compact, and flexible solution for indoor fiber termination, making it suitable for modern FTTH deployments where space, durability, and ease of installation are critical.
