IDT offers a comprehensive portfolio of linear and limiting optical transimpedance amplifiers (TIA), and driver modulators for optical networks in long-haul and metro applications. IDT's linear TIAs feature excellent gain, noise performance, and power dissipation, and are available in die form, while IDT's limiting TIAs are used for DPSK and DQPSK receivers, and are available in die and packaged form. Whether your receiver optical sub-assembly (ROSA) requires high input sensitivity, high transimpedance gain, low noise/jitter, low power consumption, or high voltage output (or a combination of all these features), IDT can provide the optimal solution.
