CS Fiber Optic Patch Cord
Double the Density, Same Faceplate
As data centers migrate to 400G and 800G architectures, fiber density in patch panels and cable management areas becomes a critical bottleneck. The CS connector – a next‑generation VSFF (Very Small Form Factor) interface – delivers a practical solution: two fibers in a 1.25mm ferrule, achieving twice the density of LC without changing your existing faceplate layout.
Feiyi Optoelectronic now offers fully customizable CS patch cords, engineered for hyperscale data centers, high‑performance computing clusters, and FTTx distribution hubs.
Why Choose Feiyi’s CS Patch Cord?
| Feature | Benefit |
|---|---|
| CS Connector (Connector Senko) | 2 fibers in a single 1.25mm ferrule – supports parallel optics (SR4 / DR4) |
| VSFF Standard | 2x density of LC, 4x density of SC – no rack redesign required |
| Uniboot Design (Optional) | Single boot manages two fibers, reduces cable bulk by 50% |
| Bend‑Insensitive Fiber | Excellent performance under tight bends, customizable fiber type available |
| OFNR / LSZH Jacket | Riser‑rated or low‑smoke zero‑halogen – safe for intra‑building and plenum installations |
| Fully Customizable | Length (0.5m – 100m), polarity (A / B / C), jacket color, fiber count (2 – 24F) |
