Equip ST to ST OS2 Duplex Fiber Optic Patch Cable — 5 m
OS2 Single-ModeST ↔ ST duplex5 m · LSZHYellow jacket
The Equip 252235 is a 5 m duplex OS2 single-mode fiber optic patch cable with ST connectors on both ends, built on 9/125 µm fiber with ceramic ferrules and an LSZH jacket — for patching legacy ST-terminated panels and equipment.
OS2 is single-mode fiber: a 9 µm core that carries light over long distances, normally with 1310 nm or 1550 nm transceivers (LX/LR-type optics). It works only with single-mode optics and single-mode infrastructure — the yellow jacket is the usual visual cue.
Connectors: ST (round bayonet twist-lock — legacy equipment and older patch panels).
Before you order: Single-mode only — the transceivers at both ends and any patch panel in the link must be single-mode (OS1/OS2, 9/125 µm). Check that the ports are ST and ST.
What's in the Box
- Equip ST/ST duplex OS2 fiber optic patch cable, 5 m (1 piece)
- Individual measurement protocol (test report) for the cable
What It Means in Practice
- Duplex = two fibers in one cable: one transmits, one receives. One cable connects one duplex port to one duplex port.
- 5 m reaches between neighbouring cabinets or from a panel to equipment a few metres away.
- LSZH jacket: low smoke, zero halogen — the usual requirement for cabling in offices, server rooms and public buildings.
- Each cable ships with its own measurement protocol — useful for documentation and acceptance tests.
What Will Not Work
- Multimode optics (SR, 850 nm) or multimode panels — single-mode and multimode fiber cannot be mixed in one link.
- Copper RJ45 ports — fiber needs an optical transceiver (SFP module) or a fiber port on the device.
- Single-fiber BiDi transceivers or simplex-only ports — this is a duplex (two-fiber) cable.
- LC or SC ports — this cable is ST to ST; check the port at both ends before ordering.
Key Features
9/125 µm OS2
OS2 is single-mode fiber: a 9 µm core that carries light over long distances, normally with 1310 nm or 1550 nm transceivers (LX/LR-type optics).
Ceramic ferrules
Ceramic ferrules keep the fiber precisely aligned for consistent, low-loss mating — the standard for quality patch cords.
LSZH jacket
Low smoke, zero halogen sheath for indoor installations where fire-safety rules apply.
Tested, with report
Each cable is measured and supplied with its protocol, so you can document the link from day one.

Frequently Asked Questions
Singular Expert Insight · Buyer's Guide
Most fiber problems we see are not the cable but a mismatch: single-mode cable on multimode optics, an LC cable where the panel is SC, or OM1 mixed into a 50 µm link. Read the transceiver label (SR = multimode, LR/LX = single-mode) and look at the port shape at both ends before you order. If you are still choosing hardware, see our switches with SFP ports.
✓ Buy it if you need a 5 m OS2 duplex link between ST and ST ports with single-mode optics.
✕ Skip it if your transceivers are multimode (SR), your ports are not ST/ST, or you need a single-fiber BiDi link.
→ Also consider the same cable in another length, or a 50/125 µm OM4 multimode cable for short-reach SR links.
Not sure which fiber you have? Send us the model of your switch, transceiver or patch panel and we will check compatibility before you order.
