Equip SC Duplex Fiber Optic Coupler, Multimode OM1/OM2 — Pack of 12
SC/UPC duplexMultimode OM1/OM2Phosphor bronze sleeve12 pcs/pack
The Equip 156145 is a pack of 12 SC duplex fiber optic couplers (adapters) for joining two SC/UPC multimode connectors — female on both sides — in patch panels, wall outlets, splice boxes and anywhere two SC patch cords must be extended or connected.
Each coupler has a phosphor bronze alignment sleeve and a dust cap, comes in beige, and is listed by Equip for OM1/OM2 multimode fiber. One coupler joins one duplex SC pair (two fibers); the 12-pack is sized for fitting out a panel or several outlets in one go.
Beige is the usual colour code for legacy multimode SC adapters, which makes them easy to tell apart from aqua (OM3/OM4) and blue/green (single-mode) adapters in the same rack.
Before you order: Equip lists these couplers for OM1/OM2 multimode. For single-mode links use single-mode (blue UPC / green APC) adapters, and check the panel cut-out fits SC duplex adapters before ordering.
What's in the Box
- 12 × SC duplex fiber optic coupler (SC/UPC female to SC/UPC female), beige
- Dust cap on each coupler
What It Means in Practice
- Female on both sides: plug an SC patch cord in from the front and another from the back to join them.
- Duplex: each coupler takes two SC connectors per side (one transmit, one receive fiber).
- In a patch panel the couplers form the front ports; behind them sit the pigtails or patch cords of the installed cabling.
- Every mated pair adds some loss — use couplers where the cabling design needs a joint, not to chain short cords together.
What Will Not Work
- LC, ST or MPO connectors — these couplers accept SC connectors only.
- APC (angled, green) connectors — this is a UPC coupler; APC and UPC must not be mated.
- Single-mode links that need low loss — Equip specifies these couplers for OM1/OM2 multimode.
- Panel cut-outs for simplex or LC quad adapters — check the cut-out size first.
Key Features
SC/UPC duplex
Takes two SC connectors per side for one duplex fiber pair.
Phosphor bronze sleeve
Metal alignment sleeve guides the ferrules into contact; Equip lists it for OM1/OM2 multimode.
Dust caps
Each coupler has a cap to keep unused ports clean — dust is the main enemy of fiber links.
12 pcs per pack
Enough to fit out a panel section or several outlets at once.

Frequently Asked Questions
Can I use them with OM3 or OM4 cords?
Equip lists these couplers for OM1/OM2 multimode. For OM3/OM4 (50 µm, aqua or violet) links we recommend adapters specified for that grade; ask us and we will match one.
Do they fit any SC patch panel?
They fit panels and outlets made for SC duplex adapters. Panels for LC quad or simplex SC adapters use different cut-outs, so check before ordering.
Is one pack enough for a 24-port panel?
One coupler is one duplex port (two fibers). A panel with 12 SC duplex ports needs one pack; 24 duplex ports need two.
Singular Expert Insight · Buyer's Guide
Couplers are simple parts, but the wrong one adds loss or does not fit: check connector type (SC), polish (UPC, not green APC), fiber type (here OM1/OM2 multimode) and panel cut-out. If you are planning the active side too, see our
switches with SFP ports.
✓ Buy it if you are fitting or repairing SC duplex ports on a multimode OM1/OM2 panel or outlets.
✕ Skip it if your connectors are LC, ST or APC, or the link is single-mode.
→ Also consider matching SC duplex patch cords in the same fiber grade.
Not sure what your panel takes? Send us the panel model or a photo of the ports and we will check before you order.
