Double Sheath FTTH Drop Cable is designed particularly to offer stable and long-lasting performance in Fiber-to-the-Home (FTTH) networks. It offers rapid internet transmission with no signal loss and high toughness for offices and homes. Double protective sheaths from the cable offer outstanding immunity to severe weather, offering applicability in rural and urban locations. Its tough construction ensures easy access to long-term longevity, holding optical connections firmly in place even in environmental exposure and heavy use.
1. Double Sheath FTTH Drop Cable Structure Design and Core Features
（1）Dual-Layer Protection
Double Sheath FTTH Drop Cable consists of two protective sheaths that make the cable much more mechanically resilient and robust.
- Inner Protective Sheath – Provides coverage for the optical fibers against mechanical impact, bending stress, and compression damage, ensuring the integrity of the core during installation and operation.
- Outer Protective Sheath – Made of LSZH or HDPE materials, this layer offers enhanced resistance to moisture, UV radiation, and temperature variations ranging from -40°C to +70°C.
- High Tensile Strength – With this dual protection, the cable achieves tensile performance up to 600N, ensuring optical stability and minimal signal loss during long-distance transmission.
（2）Easy Installation and High Durability
- Compact and Lightweight Design – With a diameter of only 4.8mm–5.0mm, the cable is light yet resilient, ideal for both indoor and outdoor applications.
- Excellent Flexibility – The bending radius can be as small as 30mm, making routing and corner installation easier without compromising fiber performance.
- Versatile Installation Options – It can be conveniently deployed on poles, along walls, or in underground ducts, adapting to various FTTH layouts.
- Efficient Handling – The smooth outer sheath minimizes friction during pulling, reduces installation time, and lowers labor costs while maintaining stable optical transmission.

（1）LSZH (Low Smoke Zero Halogen) Sheath
LSZH double sheath cable is designed for indoor and semi-outdoor applications where fire resistance and safety are of prime importance. The cable produces minimum smoke and toxic fumes when burnt, and hence safe for use in domestic zones.
Representative Models:
- 1F 5.0mm SM FTTH Drop Cable LSZH – Double Sheath 600N
- 2F 4.8mm SM FTTH Drop Cable LSZH – Double Sheath
- 2F 5.0mm SM FTTH Drop Cable LSZH – Double Sheath
（2）HDPE (High-Density Polyethylene) Sheath
HDPE cables are outdoor cables. The outer sheath has high UV light, water, and impact resistance with good stability under various climates.
Typical Models:
- 1F 5.0mm SM FTTH Drop Cable – Double Sheath HDPE – High Tensile
- 1F 5.0mm SM FTTH Drop Cable – Double Sheath LSZH – High Strength
3. Double Sheath FTTH Drop Cable Applications
Double Sheath FTTH Drop Cable can be utilized in different installation conditions:
