BendBright™ XS 200 µm Single-Mode Optical Fiber

BendBright™ XS 200 µm Single-Mode Optical Fiber
Product description

BendBrightXS fibers, available in 200, 180 and 160 µm sizes, enable cable designers to significantly reduce the diameter of micro outside plant (OSP) cable designs. This feature allows for increased fiber density in ducts and on reels, while also lowering cable weight. Additionally, it can substantially decrease the total cost of ownership for a network while minimizing the environmental impact of its deployment, making your network infrastructure more eco-friendly. 

BendBrightXS 200 µm surpasses the ITU-T G.657.A2 standard, and is fully backward compatible with G.652.D IEC 60793-2-50 low water peak specifications. BBXS features an 8.8 µm Mode Field Diameter at 1310 nm, and is rated to a 7.5mm bend radius. 

Prysmian’s Advanced Plasma and Vapor Deposition (PCVD and APVD™) manufacturing process ensures the highest quality and purity of fibers. This unique process allows unmatched performance, especially in high density, high fiber count cables. 

Thanks to the quality of modern coatings with Prysmian’s patented ColorLock, there is no need to compromise on overall fiber quality or performance. With BendBrightXS cables, you can trust in the reliability and efficiency of your network

Bend Insensitive Fibers 

Bend-insensitive single-mode fibers (ITU-T G.657.x) play a crucial role in the global transition to flexible and reliable connectivity. These fibers are uniquely capable of maintaining the entire fiber spectrum, particularly at longer wavelengths (1625 nm and above), by significantly reducing losses associated with macro-bending and micro-bending.

 

Key Features 

  • Bend Insensitive Design: BendBrightXS is a truly bend insensitive fiber optic cable, built to dramatically reduce signal loss due to macro-bending and micro-bending, even at small radii or tight routing spaces.
  • Compact and Lightweight: Available in 200 µm,180 µm and 160 µm sizes, these fibers enable the highest density cable designs and reduced cable diameters, lowering both the weight and the footprint of aerial and duct-installed cable.​
  • Cost and Environmental Benefits: Smaller cables reduce the total cost of ownership, ease installation in existing duct pathways, and minimize the environmental impact during deployment.
  • Standards Compatibility: BendBrightXS bend insensitive single-mode fiber exceeds ITU-T G.657.A2, and is fully backwards compatible with G.652.D optical fibers, ensuring seamless integration into modern and legacy networks.
  • Reliable Signal Integrity: Special trench-assisted cladding design and advanced coatings confine light within the core, guaranteeing excellent performance across the full telecom spectrum—including longer wavelengths up to 1625 nm and above.
  • Easy Handling and Splicing: The high quality coatings allow for easy fiber management, durable installation, and compatibility with standard fusion splicing—critical for field and data center deployments.
  • Future-Proof: Designed for evolving applications such as 10G-PON, WDM-PON, and multi-band transmission environments.

FAQs

What is the BendBright XS 200 µm Single-Mode Optical Fiber? 

BendBrightXS 200 µm is a bend insensitive single-mode fiber engineered with a reduced outer diameter, enabling compact cable designs and high fiber density deployments while maintaining superior signal integrity and future-proof compatibility.​ Its enhanced macro-bending behavior further guarantees that all transmissions bands up to 1625 nm (L-band) will be available for future use in this hungry bandwidth environment.

 

How is BendBrightXS different than standard optical fiber? 

Unlike conventional fibers, BendBrightXS bend insensitive fiber optic cable features a trench-assisted cladding and advanced coatings that significantly lower signal loss caused by tight bends or micro-bending. BBXS exceeds ITU-T G.657.A2 standards for bending performance, making it ideal for modern networks with space constraints and rigorous routing needs.

 

Why is bend performance important in fiber optic networks? 

Improved bend performance allows for smaller cable designs, higher installation density, and maintains reliable high-speed data transmission even in installations with sharp turns or confined spaces. This benefit is vital for efficient network expansion, minimizing signal attenuation and ensuring robust connectivity.​ Enhanced macro-bending performance further guarantees that all transmissions bands up to 1625 nm (L-band) will be available for future use in a bandwidth hungry environment.

 

Where is BendBrightXS typically used? 

Bend insensitive single-mode fiber like BendBrightXS is used in access networks, long-haul backbone deployments, indoor/outdoor installations, AI and high-density data centers, FTTH, FTTA, and distributed network architectures—anywhere a combination of compact size and high performance is required. It is ideally used in microduct cables such as Prysmian’s Sirocco™ or MicroFlex™ families.

 

What makes Prysmian a leader in optical fiber manufacturing? 

Prysmian’s Advanced Plasma and Vapor Deposition (PCVD) manufacturing processes ensure the highest optical fiber quality and reliability. Prysmian’s proprietary ColorLock™ coating process further enhances the protection and longevity of cables in the network. Color is normally applied after the secondary coating to fibers, but Prysmian’s ColorLock™ is applied on the draw tower as part of the secondary coating. Recent studies show this process and others enable Prysmian’s cables to last 50+ years through aging tests. Prysmian sets industry benchmarks for innovative design, standards compliance, and sustainability, providing networks with state-of-the-art bend insensitive fiber solutions for current and future needs.
