Our 4.8mm Round FTTH Drop Cable with G657.B3 fiber is engineered for high-performance fiber-to-the-home (FTTH) deployments. This compact and robust fiber cable is specifically designed for indoor/outdoor cabling and Multiple Dwelling Unit (MDU) environments, providing exceptional flexibility, tensile strength, and bend-insensitive optical performance.
Manufactured using tight buffer technology, aramid yarn reinforcement, and a durable PVC outer sheath, the cable supports stable, low-loss optical transmission across a wide range of installation scenarios. If you’re looking for a cost-effective, easy-to-install solution for FTTH, this is the drop cable you can rely on.

- Optimized for FTTH and MDU applications
- Ultra-bend insensitive G.657.B3 fiber
- Tight buffer design for easy termination
- Aramid yarn reinforcement for superior tensile strength
- Compact 4.8mm round construction for easy routing
- PVC outer jacket with LSZH buffer for fire safety compliance
- RoHS compliant and environmentally safe
- Factory pre-terminated option available
- Suitable for indoor cabling and outdoor aerial installations
Built for Modern FTTH Networks
The 4.8mm Round FTTH Drop Cable is purpose-built for the challenges of last-mile fiber deployments. Its G657.B3 fiber ensures minimum signal loss even under tight bends—perfect for installation around corners, conduits, and limited-space pathways. Unlike traditional fibers, G657.B3 meets and exceeds bend radius requirements for modern, high-density optical networks.
With a tight buffer design, the cable allows quick field termination, making it ideal for installers working in tight deadlines. The tight-buffered fiber is further reinforced with 1670Dtex x 4 aramid yarn, ensuring strong mechanical protection and increased tensile load resistance, both critical for vertical or aerial installations.
Applications
The 4.8mm Round FTTH Drop Cable is widely used in:
- MDU (Multi-Dwelling Unit) Cabling
- FTTH Indoor and Outdoor Deployments
- Pre-terminated Factory Installations
- Aerial Drop Cable Installations
- Commercial and Residential Structured Cabling
Its small size, strength, and bend-resistance make it highly effective in both new builds and retrofit projects where space and installation ease are a concern.
