MPO Series

MPO / MTP Data Center Cabling Manufacturer — Cassettes, Patch Panels, Trunk Cables and Patch Cords
Fibconet manufactures 10 series of MPO / MTP fiber optic products for 40G, 100G, 400G and 800G data center cabling. The product line covers cassette modules, 1U rack patch panels, MPO trunk and patch cords, MPO-to-LC breakouts, loopbacks and MPO/MTP cleaners — enough to build a full high-density link from the MDA to the switch port without adding a second supplier.

Production runs on dedicated MPO polishing, ribbon splicing and 3D interferometer inspection lines. Monthly output reaches 150,000 pieces across the MPO family. Fiber count scales up to 72 fibers per MPO end for 400G/800G backbone applications. Single-fiber insertion loss can be controlled to 0.15 dB on assemblies built with Japanese-imported ferrules, and to typical 0.20–0.35 dB on standard builds with domestic Sanhuan ferrules.

Every finished cable is 100% inspected for insertion loss, return loss, end-face geometry, polarity, fiber sequence, length and appearance. FLUKE / EXFO electronic test reports are available after order confirmation. Products currently ship into hyperscale, telecom and enterprise data-center projects in the US, Canada, Germany, UK and Netherlands.

What Is MPO / MTP and How to Choose the Right Product
MPO vs MTP — Same Standard, Different Brand
MPO (Multi-fiber Push On) is the generic multi-fiber connector standard defined in IEC 61754-7. MTP® is US Conec’s brand-name implementation of the same MPO standard, with tighter mechanical tolerances on the guide-pin holder, spring load and internal ribbon protection. Both mate with each other and both follow the same fiber count and polarity rules. Fibconet manufactures to the MPO standard and supplies MTP-compatible builds on request; the underlying optical spec is identical.
Polarity — Type A, Type B, Type C

Polarity
Fiber Sequence
Typical Use

Type A (Straight)
1↔1, 2↔2 … 12↔12 straight-through
Point-to-point trunks with A-to-B duplex crossover in the patch cord

Type B (Reverse)
1↔12, 2↔11 … 12↔1 fully reversed
Direct connection to SFP+ / QSFP transceivers; most common for 40G/100G breakout

Type C (Pair-swap)
Adjacent pairs swapped: (1↔2, 2↔1), (3↔4, 4↔3) …
Legacy pair-flip cabling

Polarity errors are the single most common cause of link-up failure on MPO systems. Confirm polarity at RFQ stage; we ship Type A / B / C per your bill of materials.
Gender — Male (with pins) vs Female (no pins)

Male: two guide pins protrude from the end-face. Used at fixed / patch-panel ends.
Female: no pins, two guide-pin holes only. Used at the equipment / movable-jumper end.

Wrong gender at RFQ = the entire batch has to be re-terminated. Always specify Male-Female, Female-Female or Male-Male at the quotation stage.

Manufacturing Capability and Quality Control
Production Line and Monthly Capacity
Fibconet’s parent operation in optical passive components dates back to 1994. The MPO / MTP line runs on dedicated equipment: automated fiber-separating jigs, sub-micron 3D polishing machines and integrated injection-molding stations for one-piece reinforcement at the breakout root instead of simple heat-shrink. Monthly output reaches 150,000 pieces. Standard orders of several thousand pieces ship in 7–12 days; bulk orders above 20,000 pieces ship in 15–20 days.
Upstream Material Control
An MPO patch cord is only as good as its ferrule, its fiber and its ribbon splice. We control the upstream stack rather than only the assembly step:

Ferrules: domestic Sanhuan ferrules on standard builds; Japanese-imported ferrules (Sumitomo class) on ultra-low-loss builds. Both selectable per order.
Fiber: YOFC / Fiberhome / HTGD single-mode and OM3/OM4/OM5 multimode, with G.657.A2 bend-insensitive fiber for tight-radius rack routing.
Aramid yarn: Taihe standard; DuPont Kevlar available on request.
Jacket compound: LSZH low-smoke zero-halogen resin; OFNR and OFNP grades available.
Ribbon splicing: high-precision ribbon fiber fusion splicers, core-by-core alignment.

100% Quality Inspection

Insertion loss and return loss: tested on every fiber of every finished cable with a dedicated IL/RL tester.
End-face geometry: 3D interferometer inspection; every finished ferrule end-face.
Polarity and fiber sequence: core-by-core verification against the bill of materials on every unit.
Length and appearance: mechanical measurement and visual inspection.
Batch environmental testing: high-low temperature cycling per batch.
Test reports: FLUKE / EXFO electronic reports available on request after order confirmation.

Certifications and Compliance
Fibconet operates under an integrated ISO 9001 / ISO 14001 / ISO 45001 management system covering quality, environment and occupational health & safety. Raw-material RoHS reports ship by default. Product-level compliance — CE, REACH, UL, ETL — is issued per model and per target market. Certification applicability varies by product and project requirements. Send us your target market and the model list; we return the applicable certificate set with the quotation.

Frequently Asked Questions
Q1. What is the difference between MPO and MTP®?
MPO is the generic IEC 61754-7 multi-fiber connector standard. MTP is US Conec’s brand-name implementation of the same standard with tighter mechanical tolerances on the guide-pin holder and internal ribbon protection. Both mate with each other. Fibconet manufactures to the MPO standard; MTP-compatible builds are available on request.
Q2. What is the highest data rate your MPO products support?
Up to 800G. The product line supports 40G, 100G, 400G and 800G stably. For 400G / 800G AI-backbone applications we recommend 24-fiber or 72-fiber MPO with the ultra-low-loss ferrule grade to preserve link budget.
Q3. What is the maximum fiber count per MPO end?
72 fibers per single MPO end. Standard 12F and 24F cover most 40G / 100G / 400G rack builds; 72F is used for 400G / 800G high-density AI backbone and supercompute cabling.
Q4. Can I mix ends — MPO on one side and LC / SC / FC on the other?
Yes. MPO-to-LC breakout is the most common configuration; MPO-to-SC and MPO-to-FC are also supported. Confirm the breakout connector type and quantity at RFQ.
Q5. Are both ends symmetric on MPO-to-MPO breakout cables?
Yes. For MPO-to-MPO breakouts (for example 24F into 2×12 or 3×8), the fiber count and configuration must be symmetric on both ends because every fiber core needs a one-to-one map. Up to 6 MPO connectors per single end are supported.
Q6. What polarity should I order for a 40G / 100G SR4 link?
Type B is the default for direct SFP+ / QSFP transceiver mating on 40G / 100G SR4. The internal crossover is done inside the cable so no external cross-connect is needed. Confirm your transceiver polarity requirement at RFQ; we ship Type A / B / C per your bill of materials.
Q7. What is the difference between standard and low-loss grade?
Standard grade holds insertion loss below 0.70 dB per mated pair; low-loss grade holds it below 0.35 dB with typical 0.25 dB. Ultra low-loss builds with Japanese ferrules reach 0.15 dB per single fiber. Low-loss and ultra low-loss are recommended for 100G high-density backbone and 400G / 800G links where every mated connector consumes link budget.
Q8. Do you 100%-test every fiber, and do you supply FLUKE / EXFO reports?
Yes. Every cable and every fiber core is tested for insertion loss, return loss, end-face geometry, polarity, fiber sequence, length and appearance before shipment. FLUKE / EXFO electronic test reports are available on request after order confirmation.
Q9. Can I get samples before placing a bulk order?
Yes. Free small-quantity samples are supplied for quality verification; you only cover the shipping cost, and that shipping cost is deducted from your first formal bulk order as a cooperation incentive.
Q10. What is your monthly capacity and typical lead time?
Monthly output across the MPO family is 150,000 pieces. Standard orders of several thousand pieces ship in 7–12 days from stock. Bulk orders above 20,000 pieces ship in 15–20 days. Custom packaging with full artwork runs from an MOQ of 30,000 pcs.
Q11. Can these MPO products be used outdoors?
The standard MPO line is optimised for data hall, MDA and rack environments (IP50, −20°C to +60°C, LSZH). For outdoor and FTTA applications, use the FTTA MPO/MTP Fiber Optic Patch Cord with an outdoor jacket, or ask for a custom outdoor build. Do not deploy the standard indoor jacket in unprotected outdoor conditions.
Q12. What is the warranty?
Standard warranty is 1 year; design service life is up to 10 years. Because 100% inspection is applied on every unit, field failures are rare; when they occur within the warranty period, we ship a replacement immediately.
