FTTH Round Cable
The FTTH Round Cable (Indoor/Outdoor) is a compact, high‑performance drop cable designed for fiber‑to‑the‑home (FTTH) networks. It features a central loose tube or tight‑buffered construction with aramid yarn strength members and a durable, round polyethylene (PE) or low‑smoke zero‑halogen (LSZH) outer sheath. Available in 1‑core, 2‑core, or 4‑core variants, it complies with ITU‑T G.657.A2/B2 standards, ensuring excellent bending performance for tight installation spaces.
Key Applications
Last‑mile access: Direct connection from the distribution point to subscriber premises, both aerial and underground.
Indoor wiring: Running inside buildings, through conduits, cable trays, or along wall surfaces.
Outdoor drop: Used in overhead lashed installations or direct burial (with optional armoring).
FTTB/FTTO: Extending fiber to businesses or office floors where flexibility and durability are required.
Harsh environments: Suitable for industrial zones, residential complexes, and rural deployments with temperature ranges from ‑40°C to +70°C.
Core Advantages
Superior bend resilience – With a minimum bending radius of 15 mm (dynamic) and 10 mm (static), it allows sharp corners and congested pathways without signal loss.
High tensile strength – Aramid yarn reinforcement provides up to 200 N of short‑term pull resistance, protecting fibers during installation.
Weather‑resistant sheath – UV‑stabilized PE or flame‑retardant LSZH resists moisture, chemicals, and rodents, ensuring long‑term reliability.
Easy termination – The round profile and standardized outer diameter (typically 3.0–5.0 mm) simplify connectorization with SC/APC or LC connectors, reducing splicing time.
Low attenuation – Typical loss ≤0.35 dB/km at 1310 nm and ≤0.25 dB/km at 1550 nm, supporting high‑bandwidth applications up to 10 Gbps and beyond.
Cost‑effective – Optimized design balances performance and material usage, lowering overall deployment and maintenance costs.

FAQ
Q1: What is the difference between round and flat FTTH drop cables?
A: Round cables offer better crush resistance and flexibility for bending in multiple directions, making them ideal for indoor conduits and tight turns. Flat cables are cheaper but less flexible and are primarily used for surface mounting.
Q2: Can this cable be used for both aerial and underground installations?
A: Yes, the standard PE sheath is suitable for aerial lashing and direct burial in non‑rocky soil. For heavy‑duty underground use, we recommend an optional steel‑tape armored version.
Q3: What is the maximum pulling tension during installation?
A: The recommended long‑term tension is 80 N, and short‑term (during pulling) up to 200 N. Exceeding this may damage the optical fibers even if the sheath appears intact.
Q4: Is the cable compatible with field‑installable connectors?
A: Absolutely. The round cable's tight‑buffered fibers (900 µm) are compatible with pre‑polished mechanical splices and fusion splice‑on connectors, enabling quick field terminations.
Q5: What warranty and lifespan does the cable offer?
A: Under normal operating conditions, the cable provides a design life of over 25 years. We offer a 5‑year product warranty against manufacturing defects and attenuation degradation.
