Indoor Metallic-Reinforced FTTH Drop Cable
The Indoor Metallic-Reinforced FTTH Drop Cable is a compact, flat LSZH cable for indoor FTTH and FTTx subscriber connections. Its two metallic strength members support controlled routing and direct termination, while the 3.2 × 2.0 mm construction accommodates 1, 2 or 4 single-mode fibers.

Indoor Metallic FTTH Drop Cable Overview
This flat indoor drop cable is designed for last-metre and in-building fiber routing where a compact construction and added mechanical support are required. Two metallic strength members reinforce the cable during routing, clipping and direct termination. The LSZH sheath is specified for indoor use; any project-specific CPR reaction-to-fire class must be confirmed separately.
The product is suitable for indoor FTTH distribution, subscriber access lines, patching between building entry points and end-user termination zones. For buyers comparing structures, you can also review the FTTH Drop Indoor Non-Metallic Cable, the standard FTTH Drop Aerial Cable and the Aerial FTTH Drop Non-Metallic Cable for span-based installations.

Indoor Metallic FTTH Drop Cable Applications
Typical installation areas
- Indoor FTTH subscriber routing
- Horizontal floor distribution and riser transitions
- Direct clipping to interior surfaces and skirting boards
- Access network and local area network connections
- Indoor interconnect and direct termination points
When this structure makes sense
Choose this structure when the route is fully indoor, the cable must stay compact, and a stronger flat geometry is preferred for cleaner handling. If the route includes tougher outdoor exposure or longer backbone sections, compare it with Multi Loose Tube Metallic Armored Single LSZH Jacket and Multi Loose Tube Metallic Armored Single PE Jacket alternatives.
Helpful technical references
Available single-mode fiber options include ITU-T G.652.D and bend-insensitive G.657 variants. See ITU-T G.652, ITU-T G.657 and the IEC 60794 cable test framework for technical context. For deployment guidance, review our FTTH guide and fiber optic cable overview.

Metallic vs Non-Metallic FTTH Drop Cable Comparison
Metallic indoor drop cable
Best suited to indoor FTTH routes where a compact flat construction and added mechanical support are needed in one cable.
Indoor non-metallic option
Review the non-metallic indoor version when a dielectric structure is preferred for indoor routing and active equipment environments.
Aerial-oriented options
For façade, pole-to-building or span-based routes, compare the FTTH Drop Aerial Cable and Aerial FTTH Drop Non-Metallic Cable.
How to Specify FTTH Drop Cable Indoor Metallic Armored
For faster RFQ handling and cleaner technical alignment, define the cable in the sequence below.
-
Confirm the route.
Define whether the installation is fully indoor, partially exposed or includes aerial transitions. Use this construction only for indoor routes. -
Select the fiber count.
Select 1F, 2F or 4F according to the required subscriber connection and spare-fiber policy. -
Choose the fiber standard.
Specify whether the project requires G.652.D, G.657.A1 or G.657.A performance. -
Confirm fire and sheath requirements.
State indoor LSZH expectations clearly, especially if the cable will run inside risers, corridors or subscriber spaces. -
Define color and termination preference.
Jacket color, connector strategy and direct termination expectations should be clarified before quotation. -
Match the structure to the real environment.
If the route becomes outdoor, armored loose tube or aerial drop structures may be more appropriate than an indoor flat drop cable.
Indoor Metallic FTTH Drop Cable FAQ
What is an indoor metallic FTTH drop cable used for?
It is used for indoor FTTH and FTTx routing, including subscriber access lines, direct termination points, horizontal distribution and riser-related indoor paths.
Is this cable intended for aerial outdoor spans?
No. This is an indoor flat drop cable. For outdoor span use, review the FTTH Drop Aerial Cable or the Aerial FTTH Drop Non-Metallic Cable.
Which fiber types can be requested?
The listed optical characteristics include 9/125 G.652.D, 9/125 G.657.A1 and 9/125 G.657.A single-mode fiber options.
What is the difference between metallic and non-metallic indoor drop cable?
The main difference is the reinforcement structure. This model uses metallic strength members, while the non-metallic indoor version is preferred when a dielectric structure is required.
What are the nominal dimensions of this cable?
The nominal flat cable dimensions are 3.2 × 2.0 mm.
