Advanced Fiber Resources (AFR) , a global leader in fiber optic components, successfully participated in Laser World of Photonics 2025, held in Munich, Germany. From industrial lasers to next-generation optical networks, AFR’s portfolio addresses the industry’s growing demand for higher power, efficiency, and bandwidth. Key exhibits include the Gain Fiber and Free-Space Pumping Isolator, 20 W Compact In-Line Isolator, 3 kW Laser Cavity Component, and Lithium Niobate modulators.
Gain Fiber and Free-Space Pumping Isolator
AFR’s Gain Fiber and Free-Space Pumping Isolator handles 150 W average power and 200 kW peak power while limiting M² degradation to < 10 %. Ideal for for high peak and high average power fiber lasers.
20 W Compact In-Line Isolator
With a typical insertion loss of 0.7 dB, a minimum isolation of 30 dB and a maximum peak power of 10 kW for ns pulses, it enables efficient optical signal management in a compact size.
3 kW Laser Cavity Component
AFR's 3 kW Laser Cavity Component integrates a high power (kW) laser combiner and a fiber bragg grating in a compact package that reduces fiber splicing, improves electro-optical efficiency, and increases reliability in high power, continuous-wavelength fiber laser systems.
AFR also showcased a range of lithium niobate modulators, including 1060 nm Phase Modulator, 70 GHz Intensity Modulator (AM70), 20/40 GHz Intensity Modulator, and a 10 Gbps Zero-Chirp Modulator.
1060 nm Phase Modulator
AFR’s 1060 nm phase modulator delivers high linearity, low drive voltage, and low insertion loss across a frequency range from DC to 10 GHz, making it ideal for phase shifting, laser beam combining, and ultra-fast, high-power lasers.
70 GHz Intensity Modulator (AM70)
AM70 is a single Mach-Zehnder modulator based on thin-film lithium niobate (TFLN) technology. It offers high bandwidth, low insertion loss, low Vπ, and excellent linearity, all in a compact package with a G3PO RF connector and DC pins. The AM70 is well-suited for both analog and digital signal transmission in applications such as radio-over-fiber (RoF), sensing, and instrumentation.
As part of the conference program, Andrea Bernardi, Internship R&D, AFR Milan, presented the talk "Ultrafast post-selection free time-bin entanglement on a thin film lithium niobate photonic chip", highlighting recent joint advancements by AFR and its partners in integrated quantum photonic devices based on thin-film lithium niobate technology.

Advanced Fiber Resources (AFR) showcased its latest innovations at OFC’2025, held April 1-3 at the Moscone Center in San Francisco. AFR highlighted several new and enhanced components designed for high performance and reliability in demanding networks.
AFR presented multiple Thin-Film Lithium Niobate (TFLN) modulator products, including the 96/130 GBaud CDM and the AM70, both of which have already achieved volume shipment. AFR also debuted its 400 Gbps/lane PAM-4 TFLN modulator chip.
During the event, AFR was invited to join the panel discussion “Commercial Readiness of TFLN Photonics,” where industry leaders shared perspectives on the commercialization path for TFLN technology. Additionally, AFR delivered a presentation at the Optica Tech Talk titled “Recent Developments in TFLN for Coherent and IMDD Applications,” exploring TFLN’s role in optical interconnects, data transmission, and quantum computing.
Vlink, AFR's subsidiary, showcased its signature Fiber Array Units (FAUs) at the event, including CPO/OCS fiber arrays and PIC coupling fiber arrays, widely used in 400G, 800G, and 1.6T high-speed/ultra-high-speed optical modules, CPO applications, coherent transmission, DCI applications, and WSS modules. Vlink's core strength lies in its advanced manufacturing and packaging technology for optical components, its expertise in designing high-speed optical interconnect solutions, and its capability to rapidly scale customized products from prototype to mass production. With highly automated production lines ensuring precision and efficiency, Vlink delivers exceptional product quality while meeting the demands of large-scale manufacturing.
C++, L++, C+L VGA EDFA Modules
Designed by B&A, AFR’s subsidiary, the VGA EDFA modules support up to 120 signal channels (C++ and L++) or 96+96 signal channels (C+L). All amplifiers offer a wide gain range, low noise figure, fast transient control, and configurable modes including variable gain, variable output power, and manual mode. Ideal for backbone networks, MAN/OTN, and DCI.
2-Pump and 4-Pump Raman Amplifiers
Designed by B&A, the amplifiers deliver high reliability and excellent optical performance with low noise figures and flat gain. Both models support C/L bands, offer pump power and signal monitoring, and include constant gain, constant output power, and manual modes. The 4-Pump model extends coverage to C+L bands, enhancing gain tilt control and managing nonlinear distortions in complex fiber environments. Adaptive tuning ensures superior noise suppression and signal integrity for backbone networks and high-speed coherent transmission systems.
