富士通FIM24202自相干解调接收模块, 内部集成光延迟解调器以及高带宽平衡探测器和跨阻放大器. 是DQPSK解调和探测的一体式小型化解决方案, 具有非常高的性价比.

40Gbps DQPSK Integrated Receiver, Fujitsu FIM24202, Fiber Coupled Module

The Fujitsu FIM24202 DQPSK receiver integrates balanced PIN/TIA (Linear + AGC) photo receiver and DLI (Delay Line Interferometer) in one package, which make the module compact and cost-effective with excellent performances. The interior PLC Mach-Zehnder interferometer features push/pull drive of DLI phase tuning for lower power consumption. And the Balanced receiver consist of PIN, TIA and peak detector for each channel, which is easy for tuning and debugging. All the components are hermetically sealed in high reliable package. It is designed for 40Gbps DQPSK optical communication systems.
