Buyer questions

Documents, drawings and test reports

What buyers usually ask before they download a catalogue or request a drawing.

Are the catalogues free, and what format are they in?
All four documents are PDF files and free to download: the product catalogue, the armored patch cord selection guide, the quality and testing documentation, and the 2026 data cable catalogue.
Do the catalogues cover every part number you make?
They cover the product families, construction options and specifications we build to. For one specific part number, our engineers prepare the datasheet or drawing and send it to you directly.
Does a test report come with each order?
Yes. Every patch cord is tested 100% for insertion loss, return loss and endface, and a per-order IL/RL test report travels with the goods.
Can you supply drawings, 3D models or a datasheet for our own part number?
Yes. Send us the drawing or the reference part number and our engineers will return the matching datasheet; if the part needs new tooling, you also get written DFM feedback before you commit.
