The AMT8312 has a bandwidth of 1.8 GHz, a dynamic range of over 23 dB and a photocurrent monitor with an output that is proportional to the average input optical power. These devices are readily designed into receivers, transceivers and transponders for SONET, Fibre Channel and Infiniband applications.
