Renesas is a leading innovator of optical drivers, transimpedance amplifiers and retimer semiconductor IC solutions for telecom (long-haul and metro) applications. Renesas features a broad family of wideband optical modulator driver amplifiers and transimpedance amplifiers to serve the exploding need for fiber optic data transmission. As the demand for bandwidth increases from service providers, datacenters and enterprise networks, these optical solutions, offering power and cost-efficiency in a small form factor, are ideal for use in metro, regional and long-haul applications. Renesas’ products include a wide range of modulator drivers and transimpedance amplifiers (TIA) for line side 100G to 400G and beyond fiber optic transmitters and receivers; as well as linear and limiting MZM drivers for long-haul and metro transmission, linear TIAs for long-haul coherent receivers and limiting TIAs for shorter range receivers.
