DIGITUS LC/UPC Duplex Fibre Optic Coupler, OS2 Singlemode, Blue
OS2 SinglemodeLC/UPC duplexCeramic sleeve≤0.2 dB
The DIGITUS DN-96007-2 is a duplex LC/UPC fibre optic coupler (female to female) for OS2 singlemode (9/125 µm) links, colour-coded blue, used to join two LC duplex patch cords or to mount LC ports in patch panels, splice boxes and junction boxes.
It carries two channels side by side, so one coupler joins both fibres of a duplex connection. Inside, a ceramic (zirconia) alignment sleeve holds the ferrules on axis; Digitus specifies insertion loss of up to 0.2 dB and return loss of at least 50 dB for the UPC end faces. Fixing screws and dust caps come with it.
Before you order: This is a LC/UPC coupler. Do not use it with APC (green, angled) connectors and do not mix multimode cords through it — match the coupler to the cords on both sides.
What's in the Box
- 1 × DIGITUS LC/UPC duplex coupler, OS2 singlemode, blue
- Dust caps
- Fixing screws
What It Means in Practice
- Join two LC duplex patch cords to extend a run without re-terminating — a typical join adds only a fraction of a dB.
- Populate an LC duplex position in a fibre patch panel or splice box; the blue colour follows the usual singlemode UPC coding, so the panel stays readable.
- Use the dust caps on every unused side: a dirty end face is the most common cause of a fibre link that "suddenly" fails.
- Mount it with the supplied screws — check that your panel uses screw-fixed couplers before ordering.
What Will Not Work
- APC connectors (green, angled end face) — they need an APC coupler; forcing them into UPC damages the end faces.
- Multimode OM3/OM4 cords — use a multimode coupler instead.
- SC, ST or MPO connectors — this coupler accepts LC only; joining LC to SC needs a hybrid coupler or a hybrid patch cord.
- Panels with snap-in-only cut-outs without screw holes — the flange/cut-out size is not published, so send us your panel model first.

Frequently Asked Questions
Can I join two duplex patch cords with it?
Yes. Plug one LC duplex cord into each side; keep the A/B (transmit/receive) orientation consistent end to end.
Does it work with OM3 or OM4 cables?
No. This is the singlemode OS2 version; use the multimode coupler for OM3/OM4.
How many do I need for a 12-port panel?
One duplex coupler per duplex port position — a 12-fibre panel loaded with duplex LC needs six.
Singular Expert Insight · Buyer's Guide
Couplers are cheap, but the wrong one stops a link: polish (UPC vs APC), mode (singlemode vs multimode) and connector type must all match the cords. DIGITUS colour-codes them so a panel is readable years later. If you are building out a fibre patch panel, see our
rack accessories for panels and splice boxes.
✓ Buy it if you are joining or panel-mounting OS2 singlemode LC/UPC duplex cords.
✕ Skip it if your cords are APC, multimode, or use SC/ST connectors.
→ Also consider the multimode LC/UPC OM3 (aqua) and OM4 (purple) duplex couplers, and the SC duplex versions.
