Product Overview

Winner single-mode bare optical fiber is engineered to meet or exceed ITU-T standards including G.652.D, G.654.E, and G.655 specifications. With a standard 9/125 μm core/cladding geometry and a 250 μm UV-cured dual acrylate coating, this fiber ensures minimal signal loss and distortion across the full operational spectrum from 1260 nm to 1625 nm.

The fiber's low cladding roundness deviation (≤1.0%) and core-cladding concentricity deviation (≤0.6 μm) ensure optimal light transmission and reduced splice loss. The cutoff wavelength of ≤1260 nm guarantees true single-mode operation, making it suitable for various deployment scenarios. Its operating temperature range of -40°C to +85°C provides durability in extreme environments.

Applications

  • Data centers requiring high-bandwidth, low-latency connections for 10G/100G Ethernet applications (G.652.D).
  • Long-haul telecommunications networks demanding precise dispersion management for efficient long-distance signal transmission (G.655).
  • FTTH deployments where high warpage tolerance and stable connectivity are essential (G.654.E).
  • 5G communication systems needing robust performance under extreme environmental conditions.

Standards & Compatibility

Winner single-mode fiber complies with ITU-T G.652.D, G.654.E, G.655, IEC 60793-2-50, and Telcordia GR-20-CORE. It is fully compatible with standard SMF connectors (LC, SC, FC), fusion splicers, and all major transceiver standards including 10GBASE-LR, 100GBASE-LR4, and OTU4. For bend-sensitive applications, G.657.A1/A2 variants offer enhanced macrobend performance down to 7.5 mm radius.
