A real FTTH splice closure manufacturer in Ningbo, China — not a trading company.
Ningbo Deju Electronic Technology Co., Ltd. is a specialized manufacturer of fiber optic outdoor enclosures based in Ningbo, Zhejiang — one of China's strongest hardware and electronics export bases.
We are not a trading company. We run our own injection molding workshop, assembly lines and an in-house testing lab. This means we control quality, lead time and price from the raw pellet to the packed carton.
Our main market is Latin America, and we keep local stock in Chile and Uruguay to shorten delivery for our distributors and contractors.
Cap-type closures from 12 to 576 cores, mechanical or heat-shrink sealed, for aerial, pole-mount and buried use.
In-line closures from 12 to 576 cores, multi-port up to 4+4, for duct, direct burial and manhole use.
G.657A1/A2 flat drop cables with 2 or 3 steel wires, white and black, 1 km per drum.
Splitters, adapters, pigtails, wall boxes and terminal boxes to complete the outside plant.
We operate 20 injection molding machines from 120T to 400T, producing our own housing shells in UV-stabilized PP, ABS and PC/ABS. We also design and store our own injection molds in-house — the housing is never outsourced.
Every lot goes through our in-house test lab before shipment: IP68 water immersion, salt spray, thermal cycling, mechanical impact and drop tests.
Weekly production reports with photos and test results keep you updated while your order is in progress.
We have delivered FTTH hardware to telecom carriers, contractors and distributors across the region. Local stock in Santiago, Chile and Montevideo, Uruguay means urgent orders arrive in 1–7 days.
