MPO cable wholesale manufacturer factory OEM
COBTEL is a MPO cable factory in Dongguan, China — not a trading company. We build MPO/MTP patch cords, trunk cables and bundled harnesses from 8 to 288 fibers in OM3/OM4/OM5 multimode and OS2 singlemode, with MOQ from 10 pcs, 7–25 day lead times, and 100% insertion loss / return loss testing on every assembly before shipment.
Cobtel Precision Electronics Co., Ltd. · Since 2006 · 41,000 m² self-owned industrial park · ISO 9001:2015 / ISO 14001 / IATF 16949 · OEM/ODM for data centers, ISPs & telecom distributors worldwide
MPO Cable Manufacturing Capability, at a Glance
COBTEL manufactures the full MPO/MTP interconnect family in-house: connector assembly, machine polishing, interferometric end-face inspection and 100% optical testing all happen inside our Dongguan factory. If your project uses MPO, we can build it — and prove it with data.
We are a vertically integrated MPO cable wholesale manufacturer: incoming fiber and ferrule inspection, MT ferrule assembly, epoxy cure, machine polishing, geometry verification, polarity mapping and automated IL/RL testing run on our own production lines. Daily patch cord capacity across 4 assembly lines is 30,000 pcs; MPO assemblies alone run at 60,000+ pcs/month.
Buyers who source from COBTEL: data center integrators and colocation operators, telecom and ISP distributors, AV/broadcast integrators, and brand owners who need private-label MPO cables with their own packaging, labels and test documentation. We ship EXW/FOB Shenzhen, DAP and DDP, and answer every B2B inquiry within 24 hours.
