Fiber Connector Identification Guide — Match Your Gear Before You Order

Visual guide to identifying fiber connectors used in live production: opticalCON DUO, QUAD, MTP, Seetronic SO2MH, SO4MH, and bare LC.

by Production Distro

The wrong connector means a cable that doesn’t plug into anything you own. Before you order tactical fiber from us — or anyone — match the connector on your existing gear against the photos below. If you’re still not sure, email a photo of the chassis port to sales@productiondistro.com and we’ll tell you exactly what cable mates with it.

Connectors we sell

Every connector below is what plugs onto the end of the cable. The chassis port (the thing built into your camera, switch, or rack panel) is the matching half. They snap together when oriented correctly.

Dual DUO (2× SO2MH per end)

aka Production Distro custom build

4 channels split into two 2-channel pairs

Mates with
Each pair plugs into a separate Neutrik opticalCON DUO chassis port
Use cases
Camera-A / camera-B routing without a breakout, redundant fiber paths, venues with DUO-only chassis infrastructure that need 4 channels in one pull
opticalCON MTP-12 high-density connector — placeholder Photo placeholder

Neutrik opticalCON MTP-12

aka 12-fiber high-density

12 channels (MTP/MPO-12 inside)

Mates with
Neutrik opticalCON MTP chassis, MTP-12 breakout assemblies
Use cases
High-density trunk runs, broadcast compound backbones, LED wall distribution to multiple processors via breakout
Bare LC duplex connector — placeholder Photo placeholder

Bare LC Duplex

aka industry-standard LC

2 channels per duplex (8/12 ch in higher counts)

Mates with
Any LC duplex port — switches, transceivers, patch panels, LC chassis
Use cases
Indoor / rack-room runs, patching to networking gear, pre-wired venues with LC bulkheads

Quick decision tree

  1. 2 fiber channels in one rugged plug? → opticalCON DUO / Seetronic SO2MH.
  2. 4 fiber channels in one rugged plug? → opticalCON QUAD / Seetronic SO4MH.
  3. 4 channels, but split across two separate plugs at each end? → Dual DUO. This is our custom build for split routing and redundancy.
  4. 12+ channels in a high-density trunk? → opticalCON MTP-12 (or MTP-24).
  5. Plain LC plug, no rugged housing? → Bare LC duplex. Indoor/rack-room runs only.

Why “Dual DUO” exists

Standard QUAD pre-terminated cable carries 4 fibers behind one connector pair. Dual DUO carries the same 4 fibers, but split into two independent opticalCON DUO terminations at each end. It’s the same cable, reorganized at the plug.

You’d choose Dual DUO over QUAD for any of these reasons:

  • Split routing — feed 2 channels to camera A and 2 to camera B without buying a separate breakout adapter.
  • Built-in redundancy — if one connector pair gets damaged on a long run, the other 2 channels keep working.
  • Existing infrastructure — the venue has opticalCON DUO chassis ports installed, no QUAD bulkheads. Dual DUO plugs straight in without adapters.
  • Faster troubleshooting — half the rig swaps out without disturbing the other half.

It costs a small premium over QUAD (roughly $140 more on a 500 ft run) because you’re paying for two extra connectors per cable. We build them in 8 mm armored construction by default.

Need help identifying a connector we don’t sell?

For connector types outside our catalog (SC, ST, MTP/MPO bare, LEMO SMPTE 304M, FC, expanded-beam, etc.), the FOA Fiber Optic Connector Identifier is the industry-standard reference. It has photos and cross-references for every common connector type used in fiber optics.

If you have a fiber port and don’t recognize it: send us a photo. We’ve seen most of them, and we’ll tell you what cable mates with it — even if the answer is “we don’t sell that, but here’s who does.”
