Returns & Support
What's your return policy?
You have 30 days from delivery to return unused items in their original packaging. Defective or incorrectly shipped items are replaced or refunded at no cost to you. Full details on our Returns & Refunds page.
Can I exchange a cable for a different length?
Yes. The fastest way is to return the original for a refund (within 30 days, unused, in its packaging) and order the length you need. If you're not sure which length to buy, email us first and we'll help you measure the run.
My cable arrived damaged or doesn't work — what now?
Email contact@nipponlabs.com with your order number, a short description, and a photo if possible. We'll send a replacement or issue a full refund.
Choosing the Right Cable
Which Ethernet category do I need — Cat6, Cat6A or Cat8?
For most homes and offices, Cat6 handles 1G everywhere and 10G over shorter runs; Cat6A carries 10G a full 100 meters; Cat8 is for short, high-throughput links in racks and server rooms (40G up to 30 m). Our guide Cat6 vs Cat6a: Which Do You Actually Need? breaks it down.
What do CM, CMR, CMP, CL2 and CL3 ratings mean?
They're fire-safety jacket ratings that determine where a cable can legally be installed — in walls, risers, or air-handling plenum spaces. Read Cable Fire Ratings Explained before running cable through walls or ceilings.
Do you sell certified cables?
Yes — we stock VESA-certified DisplayPort 1.4, Ultra High Speed certified HDMI 2.1, ETL-verified bulk Ethernet, and UL/cUL-listed power cords. Certifications are listed on each product page.
Which HDMI cable do I need for a long run?
Passive copper HDMI is reliable to about 25 ft at full bandwidth; beyond that, look at active or CL3-rated in-wall options. See What HDMI Cable Do You Need for a Long Run?
