Indoor Fiber Optic Cable
DYS indoor fiber optic cables cover simplex, duplex, distribution, breakout and armored constructions for risers, plenums and equipment rooms. LSZH jackets and UL OFNP/OFNR and CPR ratings make them ready for North American and European buildings. Tight-buffered designs simplify connectorization, while breakout and distribution cables support high fiber counts in structured cabling — all manufactured to a consistent ISO 9001 standard.

Choosing the right product
Pick by fiber count and mechanical exposure:
- Single-fiber patch or pigtail → GJFJV simplex round — thinnest and lowest cost.
- Duplex equipment jumper → GJFJBV flat — paired fibers in one flat jacket.
- Multi-fiber in-building backbone → GJPFJV distribution — 4–12 color-coded fibers in a compact OD.
- Rugged, individually terminated runs → GJBFJV breakout — each fiber separately reinforced for direct connectorizing.
- Crush- or rodent-exposed paths → GJSJV / GJSJBV armored — the steel tube takes 2000 N crush.
How to choose
DYS indoor cables use 900 µm tight-buffered fiber with aramid (Kevlar) strength members, run −20 to +60 °C, and ship with PVC, OFNR (riser), OFNP (plenum) or LSZH jackets. Pick by fiber count and how exposed the run is:
Model | Type | Cores | OD (mm) | Best for |
|---|---|---|---|---|
GJFJV | Simplex round | 1 | 1.8 / 2.8 | Pigtails, single-fiber patch |
GJFJBV | Duplex flat | 2 | 3.0 × 5.4 | Equipment jumpers, duplex patch |
GJPFJV | Distribution | 4–12 | 4.8–6.8 | In-building riser / backbone |
GJBFJV | Breakout | 4–12 | 7.4–12.5 | Direct-terminate, each fiber reinforced |
GJSJV | Armored round | 1 | 1.8 / 2.8 | Crush- or rodent-prone runs |
