FTTH Build Out Style Fiber Optic Attenuator Male to Female 3dB 5dB
7dB 10dB
The attenuators have been designed to supply high performance with
stable
Attenuation values at low cost for large volume applications.
Standard attenuation values available are: 5, 10, 15 and 20dB.
Other attenuation values can be
CusCustomdered to your specific requirements. The all-fiber
attenuator design uses no filters, air-
gap Gapgaps or light path discomtinuities instead achieve
attenuation by controlling absorption ofht energy using ion-doped
fiber technology.
This technology results in a polarization-insensitive device with
high power handling, environmental stability, and stable response
across the bandpass range. The Attenuators are designed to meet
Telcordia GR-NWT-000910.
