Description
Coractive’s attenuation optical fiber (ATN) products have been specifically designed to provide flat attenuation. Wideband uniform attenuation ensures full compatibility with current and future DWDM, CATV and other telecom systems. The ATN-FBL has a wide attenuation range (<0.4 dB/cm) for manufacturing patchcord-type attenuators used in telecommunications.

- Industry-standard fiber geometry – provides high-precision core alignment for more efficient fiber coupling
- Precise cladding diameter control – perfect ferrule fit reducing manufacturing costs & increasing production yield
- Tight attenuation tolerance – enables compatibility with DWDM network applications
- Guaranteed attenuation in 1310 nm and 1550 nm wavelength ranges
- Exceptional batch-to-batch uniformity – ensures a consistent and high-quality attenuator
- Wide attenuation range: from 0.005 to 0.4 dB/cm
Applications
- Patchcord-type attenuators
- Telecom (DWDM, CATV)
