Key Product Features
-
High-Performance OS2 Glass: Optimized with “Low Water Peak” characteristics to ensure peak performance across the entire 1260nm to 1625nm wavelength spectrum.
-
12-Core Standard Configuration: Perfectly sized for standard 12-port fiber patch panels and MPO/MTP termination, offering a clean and scalable solution for network closets.
-
Future-Proof Bandwidth: Unlike multimode fibers, OS2 Singlemode has no modal dispersion limits, making it fully compatible with next-generation 400G and 800G hardware.
-
TIA/EIA Color-Coded Cores: All 12 fibers are individually color-coded for rapid identification, reducing installation time and errors during fusion splicing.
-
Robust Environmental Shielding: Features a durable outer jacket and internal strength members (typically aramid yarn) to protect the glass cores during high-tension pulls.
Primary Applications
-
Building-to-Building Links: Creating high-speed, interference-free connections across a corporate or university campus.
-
Enterprise Backbones: Serving as the primary vertical riser or horizontal link for large-scale networking environments.
-
ISP & Telecom Infrastructure: Ideal for Fiber-to-the-Building (FTTB) and distribution point aggregation.
-
Security & Surveillance: Long-haul transmission for high-resolution IP camera networks over distances that exceed multimode limits.
