Z Fiber® / Z-PLUS Fiber® -World's lowest attenuation record 0.148dB/km-
Pure Silica Core Fiber was developed in 1980's and mainly used for Submarine Optical Cable application or other R&D activities in which extremely low attenuation is required. The typical Attenuation at 1550nm is 0.170dB/km for Z Fiber® and 0.168dB/kmfor Z-PLUS Fiber®. The fiber also has excellent performance against Hydrogen & Radiation because no Germanium is doped in manufacturing process. Special heat resistant coatings or Fiber in Stainless Steel Tube is available for harsh operating environments.

PureAccess® / PureAccess®-Ultra
PureAccess® is categorized as standard Single Mode Fiber(ITU-T G.652). The biggest difference from conventional Optical Fiber is its excellent bending performance.
Hytrel coating for Stable temperature property or Nylon coating for higher strength is available upon customers' request.
| Allowable bending radius |
| PureAccess® | 15.0 mm |
| PureAccess® -Ultra | 7.5 mm |

H-PCF is consists of silica Core & Plastic Clad. Better performance than All Plastic Fiber & lower cost than All Glass Fiber is achieved with H-PCF. Easy connectivity and High strength is also key features of H-PCF.
H-PCF is widely used for various applications from traffic surveillance cameras, Electric Toll Collection (ETC) to Factory Automation.

Benefit 1 Low System Cost |
The cost for optical modules is dominant in the total cost of optical transmission system. By reducing the cost of optical modules, the total cost could also be dramatically reduced.
|
Benefit 2 Crimp & Cleave connectors are applicable |
With conventional Glue & Polish-type optical connectors, a time-consuming gluing process and a skill-requiring polishing make it difficult to terminate them on-site, driving up cost.
|
Benefit 3 Lower attenuation than Plastic Optical Fiber |
