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

Alxenses Co., Ltd. offers fiber Bragg gratings (FBG) manufactured in optical silica fibre by UV‑laser inscription of periodic refractive index changes. The gratings are available with acrylate or polyimide coating; polyimide tolerates temperatures up to 300 °C while acrylate is limited to about 85 °C. Alxenses specifies reflectivity above 90 % and insertion loss below 0.5 dB, with a typical bandwidth of 0.2 nm. Grating length is commonly 10 mm, yielding a side‑lobe suppression ratio exceeding 30 dB.

In the industry, such gratings operate primarily in the 1510‑1590 nm wavelength band, where the periodicity defines the reflected wavelength. Standard coating choices allow deployment from ambient to high‑temperature environments, matching IEC 60785 sensor requirements. Multiplexing of up to 100 FBGs on a single fibre is typical for distributed sensing networks. The silica core provides low loss, supporting the high reliability that Alxenses advertises.

Applications include strain, temperature, displacement and humidity monitoring for power‑substations, wind‑farm turbines and civil‑infrastructure projects. Buyers such as utilities, oil‑and‑gas firms and research institutes should verify coating type, temperature rating and request performance test data before ordering. Trade can be organised under CIF or FOB incoterms, with payment and lead‑time details to be agreed directly with the Hong Kong‑based supplier.

Alxenses Co., Ltd. is located at Unit F, 18/F, Block 1, Golden Dragon Industrial Centre, No.152‑160 Tai Lin Pai Road, Kwai Chung, New Territories, Hong Kong. The company is listed as an imported‑tier supplier with a harbor trust tier, indicating that its trade history is recorded but buyer‑initiated verification is limited. The platform shows a response rate of 0 % and no average response time, which suggests that communication may need to be initiated proactively. The address places the firm in a recognised industrial zone that hosts a number of optical‑component manufacturers.

The catalogue entry notes that Alxenses provides a series of fibre‑optic components centred on FBG technology, including both acrylate‑coated and polyimide‑coated gratings. Their product description highlights high reliability, stability and low loss, positioning the range for sensing and communication applications. No additional certifications, MOQ or lead‑time information is supplied, so buyers should request these details directly. The supplier’s focus on FBGs differentiates it from broader optical‑component distributors.
