Toronto, Canada – GAO Fiber Optics has released its manual variable optical attenuator which is intended for optical power control and equalization for WDM systems, FTTx, OADM ,OXC, CATV and measurement instruments. It is commonly deployed in fiber optic systems where the optical power from source is too high for the test equipment in use – the PC board mountable attenuator is an ideal, cost-effective solution..
GAO Fiber Optics’ manual variable optical attenuator has an epoxy-free optical path and is highly stable and reliable. The attenuator features insertion loss of less than 1.5dB, return loss of over 55dB and polarization dependent loss of less than 0.2dB. It reduces the amplitude, or power, without appreciably distorting the waveform. The maximum handling power is 300mW and the attenuation level in dB ranges from 10dB to 45dB.This variable attenuator works at wavelengths from 1290nm to 1625nm at the temperature range of -5°C to 75°C.
