HS004-15 FDB ODB FAT FTB FTTH Indoor Fiber Rosette Box 4-Core SC/LC Wall Outlet IP65 myhopshun
Product Description
The HS004-15 is a 4-core FTTH indoor fiber optic wall outlet (also known as a Fiber Rosette Box, FDB, ODB, FAT, or FTB). It serves as a termination point connecting incoming fiber cables with patch cords, integrating splicing, termination, storage, and connection functions. It features an embedded surface frame design that allows for tool-free installation and removal. Measuring 191×120×44mm with an IP65 protection rating, it supports SC simplex or LC duplex adapters and has a maximum capacity of 4 cores. It is suitable for work area subsystems in homes, offices, or enterprises, making it an ideal terminal device for FTTH networks.
Why is the 4-core FTTH wall outlet (FDB/ODB/FAT/FTB) the preferred choice for residential FTTH?
In North American and European FTTH deployments, “FAT” (Fiber Access Terminal) typically refers to an indoor access terminal, while FDB/ODB (Fiber/Optical Distribution Box) are general terms for such units. The HS004-15 is a 4-core terminal box specifically designed for these indoor work area scenarios.
Featuring an embedded surface frame design, it can be installed or removed without tools, making it particularly suitable for finished homes or offices. Its IP65 protection rating prevents dust ingress, and it is compatible with mainstream fiber interfaces via SC simplex or LC duplex adapters.
Embedded Surface Frame: The white housing features a clean, embedded design with no visible screws on the front, offering an aesthetically pleasing look suitable for indoor environments.
Flip-style Splicing Tray: Upon opening the cover, the white circular splicing tray can be flipped upward to reveal the fiber storage area beneath. The tray includes multiple cable management slots to ensure fibers maintain a proper bend radius.
Protective Door and Dust-proof Structure: The unit features a protective door design that prevents dust entry while maintaining the IP65 protection rating.
Dual Cable Entry Ports: Two cable entry ports at the bottom accommodate patch cord connections and are compatible with 5m, 10m, and 20m transparent fiber optic cables. SC Simplex/LC Duplex Adapter: Supports installation of SC Simplex or LC Duplex adapters; features 4 SC/FC output ports with a maximum capacity of 4 fibers.
Metal Lock: Equipped with a metal lock on the front to prevent unauthorized opening.
Accessory Kit: Includes a complete accessory kit containing mounting screws, wall anchors, keys, etc.
