FRM5W232 series are wide band APD preamplifier receivers optimized for multi-rate from 156 Mbit/s up to 3.2 Gbit/s. FRM5W234 series are high sensitivity APD preamplifier receivers optimized for multi-rate from 156 Mbit/s up to 2.7 Gbit/s and also DWDM application. InGaAs APD chip and 3.3V GaAs IC preamplifier are integrated in 5pin coaxial type package. Single-mode fiber pigtail and LC receptacle are available as optical interface. These devices are in compliance with ITU-T recommendations and Telcordia requirement.
