A Low-Loss MTP/MPO Patch Cable Built for Tight 40G and 100G Link Budgets
In a parallel-optic channel, connector loss decides how many patch points you can afford before the link fails certification. This 12-fiber OM4 jumper is designed around that limit.
OM4 fiber delivers 4700 MHz·km modal bandwidth, stretching 40GBASE-SR4 to 150 m, while the low-loss MT ferrule keeps typical insertion loss below 0.30 dB per mated pair. You get longer runs and more room for cassettes and panels within the same budget.
It plugs straight into QSFP+ and QSFP28 SR4 transceivers, feeds MTP-to-LC breakout cassettes, and links panels across spine-leaf rows. Every cord ships with its end-face verified, so acceptance testing starts from a known baseline instead of a guess.

Why Data Center Buyers Order These Wholesale OM4 MPO Patch Cords
Four practical reasons network integrators and colocation operators standardize on this cord for volume projects.
Racks Can Sit Further From the MDA
At 40G SR4 the reach rises from 100 m on OM3 to 150 m, and at 10G from 300 m to as much as 550 m. Attenuation also drops to ≤3.0 dB/km.
That extra 50 m often removes an intermediate distribution point, along with the connectors, panels and labor that come with it.
Loss Grades That Match the Channel
Worst case across three mated pairs is 1.50 dB on the low-loss grade and 2.10 dB on standard grade.
On a 100G SR4 channel close to 100 m, that 0.60 dB is frequently the margin between pass and fail. Order low-loss for long, multi-hop links and standard grade for short in-rack patching.
One Part Number Across Speed Migrations
40G QSFP+ SR4 runs on fibers 1–4 (transmit) and 9–12 (receive). The same MTP-12 cable breaks out to six LC duplex links and supports 40G to 4×10G and 100G to 4×25G migration.
Your team stocks fewer SKUs and keeps spares useful when the network moves to the next speed.
Fewer Mis-Patches in Mixed Halls
The violet jacket marks the fiber grade at a glance, and the black boot marks 12 fibers (grey is 8, red is 24).
Technicians working moves, adds and changes in OM3/OM4 environments can identify cords without reading labels.

How to Specify the Right Gender, Polarity and Loss Grade for Your MPO Jumpers
Most ordering mistakes with multi-fiber patch cords come down to gender or polarity. Use this guide before you send a purchase order.
| Your connection | Order this | Reason |
|---|---|---|
| Direct to a QSFP+ or QSFP28 port | Female end at the transceiver | The transceiver interface is male |
| Panel to panel through adapters | Female to female | Panel adapters supply the alignment pins |
| Standard data center channel, unsure of design | Female to female, Type B | Covers most common layouts |
| Long run or several mated pairs | Low-loss grade | Keeps total connector loss inside budget |
| Linking into existing OM3 | Keep critical 40G/100G links OM4 end to end | A mixed link performs at OM3 limits |
Still unsure? Attach your cabling drawing to the quote form and our engineers will check the configuration before production.
Push-Pull MT Ferrule Construction That Holds Each Patch Cable Within Grade
Loss figures only matter if they stay stable after repeated mating. These build details are what keep them there.
Guide-Pin Alignment
Precision guide pins register all 12 end-faces in one mating, with pins on male connectors and matching holes on female.
Consistent alignment keeps insertion loss inside grade through repeated re-patching.
Tool-Free Push-Pull Latch
Connectors mate and release with a simple push-pull action, with no assembly tools.
In dense panels, installers work one-handed without disturbing neighboring cords.
Three Cable Builds
Ruggedized round cable for exposed routing, oval cable to cut pathway bulk, bare ribbon for protected cassette interiors.
You avoid paying for jacket protection the enclosure already provides.

Factory-Tested Multi-Fiber Patch Cords With Individual Test Reports
Twelve end-faces share one ferrule, so a single flaw can pull an entire 40G/100G link out of spec. That is why testing here is per cable, not per batch.
- 3D interferometry on every cable to verify MT ferrule end-face geometry before shipment.
- Loss checked against the ordered grade: maximum <0.50 dB for low-loss, <0.70 dB for standard, return loss ≥20 dB.
- Individual reports on request for your handover files and client acceptance.
- TIA-598 color coding on jacket and boot for auditable installations.
If your tender calls for specific compliance documents, list them in your RFQ and Evolux will confirm availability before quoting.

Buyer Questions About 12 Core OM4 MTP MPO Patch Cords
Should I choose OM4 or OM3 for a new 40G/100G build?
Choose OM4. Its 4700 MHz·km bandwidth is more than double OM3's 2000 MHz·km and extends 40G SR4 from 100 m to 150 m. The price gap is now small, so the extra reach costs very little.
Can I connect these cords to OM3 cabling already in the building?
Yes. Both use 50/125 µm fiber and 850 nm VCSEL optics, so they work together. The link will perform to OM3 limits, though, so keep critical 40G/100G channels OM4 from end to end.
Which connector gender do I need for QSFP28 transceivers?
QSFP+ and QSFP28 ports are male, so the cord end must be female. Panel-to-panel runs are usually female to female because the adapters supply the pins. Evolux builds every gender combination and recommends female-to-female Type B for most standard data center channels.
How much insertion loss should I budget per connection?
Allow up to 0.50 dB per mated pair on the low-loss grade and 0.70 dB on standard grade; typical values are below 0.30 dB and 0.50 dB. Add every mated pair to the fiber loss for the total. As a manufacturer testing each cable, Evolux can supply individual reports to support that calculation.
Can you supply 8- or 24-fiber versions on the same order?
Yes. The 12-fiber format is the most common because it carries 40G SR4 and breaks out cleanly to six LC duplex ports, while 24-fiber suits applications such as 100G SR10. Evolux manufactures all three fiber counts, so mixed orders come from one factory.
Do MTP connectors need different cleaning tools from LC?
Yes. Use a cassette or reel-type MTP cleaner that sweeps all 12 end-faces in one pass, plus a microscope with an MTP tip for inspection. Clean before every mating and keep dust caps on, since dirt on one fiber can degrade the whole link.
