I'm reaching out to get more detailed information regarding your optical fiber products. Specifically, I'm interested in understanding the variety of options you offer, including their specifications, pricing tiers, and any bulk order discounts you may have available. We are looking to evaluate which product lineup fits best with our current needs and future projects. Additionally, could you provide insights on the technical performance of these fibers, such as bandwidth, attenuation levels, and any certifications they may hold? If you have product catalogs or datasheets, please send those as well. This info will be crucial for us to make an informed decision moving forward. Thanks!
