Celesta – Intelligently Bonded Ribbon Cable

STL's Intelligently Bonded Ribbon (Rollable Ribbon) cable portfolio delivers high fiber density and faster deployment for AI, hyperscale data centers, metro, and long-haul networks. Powered by STL's patented rollable ribbon technology, these cables combine loose-fiber flexibility with the speed of mass fusion splicing. The portfolio includes Duct, Armored (SJ), Armored (DJ), Flat Drop, and Airblown Outdoor variants for scalable, cost-efficient network deployments.

STL Celesta Duct cable is designed for duct installations, combining Intelligently Bonded Ribbon (Rollable Ribbon) technology with high fiber density. Its flexible ribbon construction enables faster mass fusion splicing while ensuring efficient installation and reliable long-term network performance.

STL Celesta Armored (SJ) cable features a single-jacket armored construction that provides enhanced mechanical protection for outdoor deployments. Its robust design safeguards the fibers against external impacts while maintaining installation flexibility and long-term reliability.

STL Celesta Armored (DJ) cable features a double-jacket armored construction for superior protection in harsh outdoor environments. Its reinforced design resists mechanical stresses and environmental exposure, ensuring dependable performance in demanding network deployments.

STL Celesta Flat Drop cable is engineered for last-mile and FTTH deployments, offering a compact flat-profile design for easy routing and installation. Its optimized construction delivers reliable optical performance while simplifying deployment in access networks.

STL Celesta Airblown cable is optimized for installation in microduct networks using air-assisted deployment. Its lightweight construction enables rapid installation, high fiber density, and scalable network expansion with minimal disruption.

Celesta – Intelligently Bonded Ribbon Cable

Exponential connectivity requirement and next-generation technologies have taken the world by storm. Whether in 5G or FTTx, governments and network providers across the world are under constant pressure to provide gigabit, ubiquitous connectivity to enable enterprise-grade connectivity from homes for online education, work, shopping, entertainment; bring connectivity in suburbs at par with that of commercial areas; allow for the seamless convergence of fixed, mobile and broadcast networks; and facilitate the Internet of Things between interconnected objects and devices.

Intelligently bonded desing of the cable can easily take the shape of a bundle and improves the form factor of the cable. STL 432F Celesta Ribbon cable is 26% smaller than a conventional Loose tube cable

STL Celesta is the ideal solution for space constrained locations. The 432F cable can be easily blown inside a 20mm duct

- 2Km length of STL 432F celesta ribbon cable can be installed within 1 hour. - Innovative Gel free and contra helical binding desing helps installer perform end preperation in under 3 minutes. - Colour coded bond design help splice the ribbons in 80% lesser time as compared with traditional loose tube cables.

Bend insensitive fibre helps improve network's power budget, hence the lifetime of the network by accomodating more number of repairs
Smaller size of the cable helps Network operatorssave capex and opex due to reduced size of passive infrastructrue and logistics cost
