    LightCounting: NPO Is Hot, but Pluggables Remain the Market Mainstay

    LightCounting's latest quarterly report says NPO dominated much of the discussion at the recent CIOE, much like the industry's enthusiasm for LPO a few years ago. However, sales of retimed pluggable optical modules continue to hit new highs, with Ethernet optical modules accounting for the majority of overall sales.

    CIOE 2026 Observations: Why NPO Is the Optimal Choice for Cloud Giants

    The 27th CIOE drew nearly 190,000 visits over three days, up 32% year on year. NPO (near-package optics) products from major domestic optical module makers made a concentrated appearance. NPO moves the optical engine from the switch front panel to near the ASIC package without soldering it to the switch chip, balancing power consumption and serviceability.

    Russell Center and Partners Report in Optica: Hollow-Core Photonic Crystal Fiber Enables Flexible Delivery of Near-Watt, Hundred-Femtosecond 2.8 µm Mid-Infrared Pulses

    The Russell Advanced Lightwave Science Center at the Hangzhou Institute of Optics and Mechanics, together with the Hangzhou Institute for Advanced Study of UCAS, the Shanghai Institute of Optics and Mechanics, and IRFIBER (Ningbo) Optoelectronics Co., Ltd., published a paper in Optica on delivering near-watt, hundred-femtosecond mid-infrared pulses in the 2.8 µm band through a 5 m-long hollow-core photonic crystal fiber with a single-core, eight-ring structure. After evacuation, overall efficiency exceeded 70%, the output was a near-diffraction-limited Gaussian spot, and the fundamental-mode energy fraction exceeded 95%.

    Why we recommend it: The paper gives efficiency, pulse duration, peak power and fundamental-mode fraction, and compares the fiber with free-space optics and solid-core fluoride fiber, making it easier to judge the applicability of hollow-core fiber to mid-infrared ultrafast delivery.

    Aio Optics Introduces SpectrumShaper-R4 Spectral Broadening Module

    Aio Optics has introduced the SpectrumShaper-R4 series spectral broadening module, extending the broadening range from 1-30 GHz to 1-80 GHz. An integrated single-frequency seed source is available as an option, and the built-in spectral profiles and software interaction have been optimized. Aimed at high-power narrow-linewidth fiber lasers, the module controls the seed spectrum through electro-optic phase modulation of an RF signal to suppress nonlinear effects during amplification.

    Why we recommend it: Changes in the broadening range and integrated seed-source options correspond to specific design requirements for narrow-linewidth fiber lasers, useful for comparing trade-offs between spectral control and full-system integration.
