Fiber Optic Cable
Fujikura’s fiber optic cable is Wrapping Tube Cable™ (WTC™) with Spider Web Ribbon™ (SWR™) technology, providing ultra-high density for outside plant applications such as Fiber To The Home (FTTH), access networks, and data centers. The cable meets the latest Telcordia GR-20 standard for outside plant cables. WTC™ with SWR™ achieves the smallest diameter and lowest weight among high-fiber count ribbon cables in the industry. SWR™ is a flexible ribbon fiber that enables efficient ribbon or individual splicing, delivering ultra-high-density packaging within WTC™.

Outdoor
The Wrapping Tube Cable™ (WTC™) with Spider Web Ribbon™ (SWR™) is an ultra-high density outside plant cable designed for fiber-to-the-home (FTTH), access markets, and data centers. It complies with the latest outside plant cable standard, Telcordia GR-20. It offers fiber counts from 144 to 13,824. Available in armored and non-armored types, it delivers industry-leading density with reduced diameter and weight.
Indoor/Outdoor
The flame-retardant Wrapping Tube Cable™ (WTC™) with Spider Web Ribbon™ (SWR™) is a high-density optical cable designed for riser-rated indoor and indoor/outdoor use. It features a gel-free,water-blocked core and a flame-retardant jacket, allowing safe installation inside buildings and in covered outdoor pathways such as ducts and trays—without the need for splicing between environments.

Microduct
Air Blown WTC™ is optimized for microduct installation using compressed air, eliminating the need for traditional pulling. This method accelerates up deployment and reduces labor costs, making it ideal for rapid network expansion.The cable’s lightweight and flexible design supports easy upgrades and expansions in existing ducts.
Aerial cable
The Self-Supporting Wire WTC™ offers a cost-effective, flexible FTTH deployment model. Its “Pay-as-you-grow” approach reduces both CAPEX and OPEX. Easy to install without special tools or training, it enables fast rollout, short project timelines, and simplified reconfiguration—ideal for scalable, efficient fiber networks.
Customer Challenges We Address
Space constraints for installation
Compared to conventional optical cables, its smaller diameter and high-density design accommodate a large number of fibers even in limited duct or rack space. It addresses space constraints in urban areas and data centers.
Construction efficiency
The Spider Web Ribbon™(SWR™) structure significantly improves fusion splicing efficiency. Combined with dedicated branching kits and fusion splice frames, it enables reduced construction time and labor costs.
Future Optical Transmission Volume
With a super-high-core configuration of up to 13,824 cores, it flexibly handles rapidly increasing communication traffic for 5G, cloud, and AI. It is also suitable for long-term network expansion.
