1. Low back reflection.
2. High power endurance.
3. Wavelength independent.
4. Low PDL.
5. Precise control of attenuation range.
6. Simple manipulation.
1. Attenuation level: 1 - 9dB ( ± 0.5dB), 10 - 20Db ( ± 5%). 2. Attenuation tolerance: ± 0.5dB ( 1 - 9dB): ± 5% ( 10 - 20dB). 3. Back reflection: <= 50dB (PC), <= 60dB (APC). 4. Polarization dependent loss: <= 0.5dB. 5. Operating temperature: -20°c ~ 70°c. 6. Storage temperature: -40°c ~ 80°c.
