What We Can Do
Fiber Optic Patch Cords, Pigtails and MPO Assemblies — All From One Factory
Yes — every product on this page comes from our own production line. COBTEL builds fiber optic patch cords for telecom networks, data centers, FTTH projects, CATV headends, campus backbones, industrial control rooms and security systems. Our fiber optic division has run since 2006, and it works today inside a Class 100,000 cleanroom.
- SC, LC, FC and ST patch cords and pigtails — simplex or duplex, UPC or APC polish, hybrid combinations welcome.
- MPO/MTP assemblies — 8, 12 and 24-fiber trunks, polarity Type A, B and C, plus MPO-to-LC breakouts, 288-core bundled harnesses, cassettes and distribution boxes.
- Fiber grades — OS2 singlemode (9/125 µm, G.652.D and bend-insensitive G.657.A2) and OM1, OM2, OM3, OM4, OM5 multimode (50/125 µm).
- Jackets and diameters — LSZH, PVC, OFNR, OFNP and PE in 0.9 mm, 2.0 mm and 3.0 mm.
- Lengths — standard stock from 0.5 m to 30 m; custom cutting from 0.3 m to 300 m.
Every connector carries a ceramic zirconia ferrule. We grind each end face on precision polishing machines and check geometry on 3D inspection equipment. The result is a cord that plugs in, tests clean and stays clean after hundreds of mating cycles.
Buyers choose this supplier fiber optic cable factory for three reasons. Capacity: our lines build 700,000 standard cords and 300,000 MPO lines every month. Consistency: the same team and the same test plan run on order one and order ten thousand. Proof: 100% of cords pass an insertion loss and return loss test before packing, and we share the batch report on request.
Who Buys From This Supplier Fiber Optic Cable Factory
Telecom contractors order SC/APC cords for FTTH rollouts. Data-center teams order fiber optic cables for 40G, 100G and 400G links. System integrators order LC and SC duplex cords for enterprise campuses and security networks. Broadcast, medical and industrial buyers choose LSZH jackets to meet fire-safety rules in occupied buildings. Different markets, same request: a supplier fiber optic cable partner who answers fast, builds to spec and proves every claim with test data. That is the job we have done since 2006, and the reason so many first orders turn into annual contracts.

Volume Buying
MPO Cable Wholesale: Factory Pricing for Distributors and Integrators
Buyers who purchase MPO cable wholesale need three things: a price that survives resale, stock they can draw on, and quality that never changes between batches. COBTEL builds its wholesale program around those three needs.
Run a forecast, and we hold finished safety stock under your label. You call off shipments weekly or monthly. The price stays fixed for 12 months, and we absorb the storage cost. This is how our long-term distributor partners keep their shelves full without tying up cash.
Distributors ask one more question: what happens when my customer finds a problem in a delivered batch? Our answer is the 3-year warranty plus a replacement shipment on the next production run. Across three years of running private-label programs, our largest defect claim equaled 47 cords out of more than 100,000 shipped — and every replacement left the factory within one week.
Every wholesale order ships with batch test reports. That is the difference between a supplier fiber optic cable factory and a trader with a price list.
OEM · ODM
OEM/ODM Service From an Fiber Optic Cable Manufacturer That Builds to Your Drawing
As a direct fiber optic cable manufacturer, COBTEL runs OEM and ODM programs for brands, distributors, integrators and telecom contractors. Because we also make our own molds, stamps and plastic parts, we control the whole chain — ferrule to box — instead of buying half of it outside.
- Private label — your logo on labels, barcode and retail packaging; free artwork on standard runs.
- Custom build — any connector mix, length, jacket, color, print text and polarity type.
- Custom molds — breakout boots and strain-relief parts made in our own tooling shop at 0.01 mm precision.
- Engineering support — design-for-manufacturing feedback within 24 hours of receiving your drawing.
- Pilot runs — 50 to 100 pieces built on the same line as mass production, so approval samples match delivery.
- Documents — drawings, test plans and material certificates filed for every program.
How an OEM Project Runs
- 1. Send a drawing, a sample or a simple spec list.
- 2. Our engineers review it and reply with feedback and a quote within 24 hours.
- 3. We build samples in 3–7 days and ship them for your approval.
- 4. You approve; we run a pilot batch and send the full test data.
- 5. Mass production starts on the locked process, and every cord is tested again before packing.
OEM/ODM Cases From Our Order Books
6,400 MPO-12 OM4 Trunks in 18 Days
A US data-center integrator needed 6,400 MPO-12 OM4 trunk cables in a non-standard 7.3 m length, polarity Type B, elite loss grade (≤0.35 dB), with private labels and sequential numbering. Our cleanroom lines produced and 100%-tested the full order in 18 days. Average measured insertion loss came in at 0.22 dB. The client has since placed two repeat orders, each one larger than the last.
45,000 Private-Label Cords a Year, Three Years Running
A German network distributor wanted a private-label SC/APC OS2 LSZH program: 45,000 cords per year across nine lengths, with their logo on the label, barcode and bag. We locked a 12-month price, held a 3,000-piece safety stock and shipped on a monthly schedule. Three years on, the defect rate stays below 0.1% and on-time delivery holds at 99.6%.
12,000 FC/APC Pigtails, Accepted on First Inspection
A telecom contractor had to retrofit an ODF site on a humid coast with 12,000 FC/APC pigtails. We validated the build in our thermal shock chamber from −40 °C to +85 °C, shipped the complete order in three weeks and supported the cutover with test reports for every batch. The site passed carrier acceptance on the first inspection.

This scale serves brands you know. Six or seven of the world’s and China’s top ten structured cabling brands buy from us directly, and our teams run OEM projects for Fortune 500 companies. When those buyers audit a supplier fiber optic cable factory, they check molds, cleanliness and test data. Welcome to audit ours.
We hold 265 patents and reinvest 5% of annual sales in research and development. National honors include “National High-Tech Enterprise” (2016) and “Little Giant” status. For you, that means custom requests get an engineering answer in hours, not weeks.
Quality Control
Six Checks Before Your Order Ships
Quality is made on the line, not inspected in afterwards. That sentence guides how we train, tool and test. Every cord passes six checkpoints:
- 1. Incoming inspection. Fiber, ferrules and cable arrive with material certificates and get sampled before release to the cleanroom.
- 2. End-face microscopy. After polishing, technicians inspect every ferrule at 400× for scratches, pits and contamination.
- 3. 100% IL/RL test. Each cord is measured for insertion loss and return loss at 0.01 dB resolution — no sampling, every unit.
- 4. Geometry sampling. 3D interferometers check radius of curvature, apex offset and fiber height against IEC limits.
- 5. Final check. Length, label, polarity and packaging are verified against your purchase order, line by line.
- 6. Pre-shipment report. Your batch number links to its test data, and the report travels with the shipment email.
Each cord carries a printed batch code, so any unit in the field traces back to its production date, materials and test record. Third-party inspection before shipment is welcome, and there is no fee from our side for the bench time.
Packing · Payment · Delivery
From Our Cleanroom to Your Warehouse
Standard packing is a coil and poly bag with desiccant, an inner box and an export carton, palletized on request. OEM orders can use retail packaging, reel winding and barcode labels. Batch test reports travel with every shipment as a PDF, so receiving and QC teams get their data before the carton is even opened.
Payment: T/T with 30% deposit and balance before shipment, PayPal for samples, and L/C for large projects. Shipping: EXW Dongguan, FOB Shenzhen, or DDP by negotiation. Air freight reaches the US and Europe in 3–7 days; sea freight suits full-pallet programs. For your protection, confirm the beneficiary name Cobtel Precision Electronics Co., Ltd. before every transfer — we publish this warning because payment fraud hurts buyers and factories alike.
