As data centers and telecom networks evolve toward higher bandwidth and greater parallelism, traditional fiber connectivity architectures are being pushed to their physical and operational limits. One of the most visible pressure points is port density. The industry’s response has been the emergence of VSFF (Very Small Form Factor) fiber connectivity, which represents not just a smaller connector, but a fundamental shift in how optical networks are designed, deployed, and scaled.

Enabling Next-Generation Optical Circuit Switches with Fiber Shuffle and Micro-Optic Solutions An Optical Circuit Switch (OCS) is a device that directly routes optical signals without converting them to electrical signals. Unlike traditional switches that handle data packets, an OCS creates a physical, dedicated light path between two points. These are increasingly important in the context of AI scale-up because they offer low latency and high bandwidth, which are crucial for the massive data transfers required for large language models and other

Hollow-core fiber (HCF) presents several compelling advantages over conventional solid-core fibers like G.652.D, including ultra-low latency, high capacity, and reduced attenuation.

Hollow-core fiber (HCF) replaces the glass core of conventional single-mode fiber (SMF) with an air-filled center. In practice HCF is built as a microstructured glass “jacket” surrounding a central air channel. Light is guided not by total internal reflection in glass but by photonic-bandgap or anti-resonant effects in the cladding. Figure 1 shows a common “revolver” anti-resonant design: a central air core with a ring of thin silica tubes. This leaves >99% of the optical mode in air, dramatically reducing interaction with glass. By contrast, an SMF has a solid Ge-doped silica core (∼9 μm diameter) within a lower-index glass cladding. Because the HCF core index (n≈1) is much lower than the cladding, special cladding structures are required to confine light.
