Fujitsu Unveils APD/TIA and PIN/TIA Receiver Modules with VOA

3/1/2004 - Fujitsu Compound Semiconductor, Inc. (FCSI) of San Jose, CA announces new APD / TIA and PIN / TIA receiver modules with integrated Variable Optical Attenuators (VOA) for 10Gb/s Wavelength Division Multiplexing (WDM) applications. The FRM5N144DS and FRM5J144DS have APD or PIN-PD, TIA and MEMS VOA in an industry standard 16 pin butterfly package. The attenuation range of the VOA is 20 dB or more. The overload characteristics have been improved by integrating VOA because VOA controls optical input power level. As a result of this, the receivers have much wider dynamic range (-24 dBm to +6 dBm for APD / TIA and -18 dBm to +10 dBm for PIN / TIA) than current receivers. And these devices are suitable for 10Gb/s WDM applications for linear operation.

FCSI's products include devices for fiber optic digital telecommunications applications in the 622 Mbs - 40 Gb/s range (laser diodes, receiver modules, GaAs IC's, LN modulators, XFPs, SFPs, and 300 pin MSA transponders), and analog lasers for CATV applications (broadcast and return path). FCSI produces lasers at ITU grid wavelengths for DWDM systems. FCSI's products also include microwave and millimeter wave RF devices for cellular, handset, broadcast and satellite communications.

Fujitsu Quantum Devices, Limited located in the prefecture of Yamanashi, Japan manufactures these products for the world markets in one of the world's largest compound semiconductor operations. These operations are ISO 9001 and ISO 14001 certified, with support facilities strategically located throughout the world for assembly and test. Fujitsu performs 100% testing to insure quality and reliability.
