Roline OS2 Singlemode Fiber Patch Cable, LC to LC, Duplex, 10 m
OS2 · 9/125 µmLC ↔ LCDuplex10 m
The Roline 21.15.8789 is a 10 m duplex OS2 singlemode fibre patch cable with LC connectors on both ends, made for singlemode links between switches, SFP/SFP+ optics, patch panels and media converters.
The cable uses an LSOH jacket with a 3.0 mm outer diameter in yellow, the standard colour for singlemode, so it is easy to tell apart in a busy rack.
Before you order: OS2 singlemode works with 1310/1550 nm long-reach (LR/LX/ER) singlemode optics only. Multimode SR/SX transceivers will not work on this cable. Check that both ports are LC.
What's in the Box
- 1 × Roline OS2 duplex fibre patch cable, 10 m, LC – LC
- Transceivers, couplers and patch panels are not included
What It Means in Practice
- Two fibres in one cable: one transmits, one receives — the normal setup for SFP, SFP+, SFP28 and most media converters.
- At 10 m it reaches between neighbouring racks or across a server room; for building backbones use installation cable and patch panels instead.
- Singlemode OS2 is the right choice for 1310/1550 nm optics (1000BASE-LX, 10GBASE-LR and similar) and for links that will be extended later over long distances.
- Respect the minimum bend radius (30 mm static / 60 mm dynamic): route the cable in gentle loops and do not pinch it in rack doors or cable ties.
- Keep the connectors covered until the moment of connection and clean the end-faces if a link shows high loss — dirt is the most common cause.
What Will Not Work
- Multimode SR/SX transceivers (850 nm) — they need OM3/OM4/OM5 cable.
- Ports of another connector type (SC, ST, MPO/MTP, E2000) without the right hybrid cable or adapter.
- Permanent in-wall or outdoor installation — this is a patch cable for racks, desks and equipment rooms.

Frequently Asked Questions
Singular Expert Insight · Buyer's Guide
Singlemode OS2 is the safe default for new fibre links: it handles 1G to 100G and long distances with the right optics. Match three things before ordering: fibre type (OS2), connector at each end (LC / LC) and polish. Typical partners are switches with SFP/SFP+ ports and the matching transceivers.
✓ Buy it if your ports are LC on both sides and the link is OS2.
✕ Skip it if your transceivers are multimode SR/SX — order OM4 instead.
→ Also consider the same cable in other lengths.
