This blog post digs into Prysmian’s new single-mode fiber optic with a 160-micron coating diameter. It’s the first commercially available bend-tolerant fiber at that size, and it could really shake up network densification, space-constrained deployments, and how well new fiber plays with existing glass.
Let’s look at the tech, what it means for data centers, 5G, and jam-packed urban networks, plus the bigger R&D push for more bandwidth in crowded places.
What is new: 160-micron bend-tolerant single-mode fiber
The main breakthrough here is a thinner coating that lets you cram more fiber into the same space, without hurting performance. With a 160-micron coating, operators can fit more fibers into conduits, buildings, or data centers.
The glass core stays at the usual 125 microns, so it still works with standard single-mode glass. Compared to the common 250-micron fiber, this new one cuts the cross-sectional area by over 50%. That’s a real boost in space efficiency.
Prysmian’s BendBrightXS tech keeps bend performance solid, even at these reduced dimensions. The ColorLockXS coating system steps in to protect the fiber and keep it bend-insensitive—pretty important when fibers have to twist around tight corners or squeeze through crowded spaces.
Key technical features
- 160-micron coating diameter lets you fit more fibers into the same spot.
- BendBrightXS technology keeps bending performance strong, even when the fiber gets thinner.
- ColorLockXS coating system protects the fiber and helps it handle bends in the field.
- The glass core stays 125 microns, so it’s compatible with existing single-mode glass.
- ITU-T compliance with G.652 and G.657.A2 means it’ll work with current deployments.
Deployment benefits and use cases
Operators and the industry are feeling the squeeze from dense cities, bigger data centers, and the needs of 5G networks. Smaller-diameter fiber goes right at the heart of these space problems, letting you run more fibers through the same ducts and cabinets.
This higher density can mean less digging, faster rollouts, and lower costs when expanding networks in crowded spots. For anyone dealing with jammed underground infrastructure and the constant push from edge computing, data centers, and 5G, the 160-micron option offers a way to add capacity without tearing up the streets or building new conduits.
Practical deployment advantages
- Space-constrained environments like tight ducts, packed conduits, and dense data centers can handle more fibers per tray or duct.
- Higher fiber density cuts down on the number of separate cables, making management easier and networks more efficient.
- Reduced civil works mean lower CapEx and quicker network expansions.
- Support for saturated underground infrastructure and growing needs from data centers and 5G by giving a scalable densification route.
Standards and interoperability
Interoperability is always a big deal for operators. Prysmian emphasizes that the 160-micron fiber still works with standard single-mode glass.
Because it matches ITU-T specs (specifically G.652 and G.657.A2), you can drop it into existing networks without needing new connectors or major changes. That really lowers the risk and lets planners boost density without going all-in right away.
Why ITU-T compatibility matters
- Continuity with current deployments means splicing, connectors, and tests still work.
- Interoperability across equipment lets you mix legacy and new optical gear with no drama.
- Future-proofing under G.652/G.657.A2 helps operators grow as demand keeps climbing.
Industry context and outlook
Prysmian sees the 160-micron bend-tolerant fiber as part of a bigger movement to meet surging bandwidth needs and network densification. BendBrightXS tech, plus the tough ColorLockXS coating, makes high-density deployments more practical for real networks.
Operators are wrestling with space limits, old underground setups, and the endless wave of data traffic. These kinds of innovations help them squeeze more capacity into existing ducts and buildings—no need for huge new construction projects.
With compatibility, higher density, and reliable bend performance, this fiber looks like a smart pick for next-gen backhaul, fronthaul, and data-center interconnects. It’s not a silver bullet, but it’s a pretty clever move for operators facing today’s challenges.
BendBrightXS and ColorLockXS: the technology edge
- BendBrightXS delivers bend-insensitive performance at the 160-micron scale, so you can run fiber safely in tight spaces.
- ColorLockXS adds tough mechanical protection and keeps bend tolerance even when you’re handling and routing fiber in the real world.
Conclusion: enabling capacity within existing footprints
Prysmian’s 160-micron bend-tolerant single-mode fiber brings together density, compatibility, and solid mechanical protection. It’s a direct answer to what modern networks are desperately looking for.
Operators dealing with crowded ducts and aging infrastructure finally have a practical path forward. With demands from data centers and 5G ramping up, this fiber lets them expand capacity without tearing up everything for new construction.
