Import Fbg (Fiber Bragg Grating) Array — Buy in Bulk from Supplier in Hong Kong

Alxenses Co., Ltd. produces fiber Bragg grating arrays by writing multiple gratings directly into a single strand of optical fiber without splicing, eliminating weak junctions that compromise mechanical integrity. Each array maintains precise wavelength spacing and reflectivity, enabling distributed sensing over distances exceeding 10 kilometers. The fabrication method ensures consistent performance under dynamic strain and thermal cycling, critical for long-term structural monitoring.

The arrays are fabricated using UV laser inscription on photosensitive fiber, resulting in a typical grating reflectivity range of 80% to 99% and a wavelength tolerance of ±0.1 nm. Standard fiber types include SMF-28e+ or equivalent, with a coating of acrylate or polyimide depending on operating temperature. Typical grating spacing ranges from 1 mm to 100 mm, configurable per application. These specifications align with industry standards for high-stability sensing systems in harsh environments.

These arrays are used for real-time strain and temperature monitoring in oil and gas pipelines, bridge structures, aircraft wings, and offshore platforms. Buyers include engineering firms, industrial sensor integrators, and research institutions requiring multipoint measurement without electrical interference. Packaging is in protective fiber reels with strain relief and labeling per customer specification. Delivery is typically via express courier with customs documentation for Hong Kong export.

Alxenses Co., Ltd. is a Hong Kong-based supplier specializing in fiber optic sensing components, with a registered address in Kwai Chung. The company operates as an importer and technical distributor, sourcing and configuring FBG arrays for industrial clients. Its listing shows no claims about manufacturing capacity, employee count, or years in operation, and response metrics are not available. It does not state certification status or client references.

The company's focus is on the technical configuration of FBG arrays rather than mass production. It does not claim to fabricate the optical fiber itself but instead applies advanced inscription techniques to create spliceless arrays. Its supply chain appears to rely on third-party fiber and laser systems, with final assembly and calibration performed in-house. No information is provided regarding inventory, lead time, or direct production facilities.
