01 · WHAT WE CAN DO

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.

06 · FAQ

MPO Cable Buying FAQ — MOQ, Lead Time, Polarity, Testing

The questions B2B buyers ask before issuing a PO — answered with the same numbers we commit to in our quotations.

What is the MOQ for MPO cables?
COBTEL's MOQ is 20–50 pcs for standard 8/12/24F MPO-MPO trunks, 100 pcs for MPO-LC harnesses and breakouts, and 10 pcs for 96/144/288F bundled harnesses. Samples of 1–5 pcs are supported before mass production, and first-time buyers may place mixed-SKU trial orders. Stocked standard lengths ship with no MOQ.
How fast can you deliver?
Samples ship in 3–5 working days. Standard MPO trunks take 7–10 working days, MPO-LC harnesses 8–12, and 96/144/288F bundled harnesses 15–25 after a 2–3 day engineering review. Stocked colors and lengths ship in 1–3 days ex-works, and every quotation is returned within 24 hours.
Standard or Elite grade — which insertion loss should I order?
Multimode Standard is rated at ≤0.60 dB maximum insertion loss (≤0.20 dB average), while MM Elite is ≤0.35 dB max (≤0.12 dB average); singlemode grades are ≤0.75 dB (Standard) and ≤0.35 dB max / ≤0.12 dB avg (Elite). For 40G/100G-SR4, SWDM4 and AI/GPU cluster links COBTEL recommends Elite, because a 4-connector link at 0.12 dB average stays well inside the 1.5 dB 40GBASE-SR4 connector budget. Every unit of both grades is 100% tested before shipment — nothing is downgraded and sold.
Which polarity — Type A, B or C — do I need for 40G/100G?
Type B (crossover, Position 1→Position 24) is the standard choice for direct 40GBASE-SR4 and 100GBASE-SR4 MPO transceiver links. Type A straight-through is used in structured cassette systems where A-B patch cords pair, and Type C is less common. Send COBTEL your switch and cassette models and the factory will confirm the polarity map — every harness ships with its own documented polarity diagram.
Male (pinned) or female MPO connectors?
QSFP transceivers carry pins, so they mate with female (pinless) MPO connectors, while cassette adapters behind panels typically need one male end per link. Gender and orientation are specified at time of order. If you are unsure, send COBTEL your equipment model or BOM — mismating is the #1 cause of MPO link loss, so gender is verified against your list before production begins.
What OEM / private-label options do you offer?
COBTEL offers laser-marked housings, Pantone-matched jacket and boot colors, branded sleeves, private-label boxes, manuals and barcode/QR labels in your part-number system, plus test reports branded in English or German. Custom packaging starts at 500 pcs. An NDA is signed before any drawings are exchanged, and 10-pc pilot runs are standard before mass production.
Do you provide test reports and traceability?
Every unit is 100% tested for insertion and return loss at 850/1300 nm (multimode) or 1310/1550 nm (singlemode). A batch test report in PDF and Excel with per-unit data travels with every shipment, and each leg is labeled with core count, polarity and connector type. Serial-level traceability supports customer audits, and the warranty is 3 years limited with 48-hour RMA response.
What are your payment and shipping terms?
Payment terms are T/T 30/70, with L/C at sight accepted for orders above USD 50,000 and PayPal available for samples. Shipping options include EXW Dongguan, FOB Shenzhen, DAP and DDP, with courier delivery (DHL/FedEx/UPS) in 3–7 days or sea freight for full-container blanket releases. Wire transfers are accepted only to the verified account name "Cobtel Precision Electronics Co., Ltd." — confirm by phone at +86 138 2911 7062 before payment.
