NeoPhotonics Corporation specializes in the design, manufacture, and sale of optoelectronic components and modules that are crucial for transmitting and receiving high-speed digital optical signals. Their products primarily serve cloud and hyperscale data centers, internet content providers, and telecommunications networks. The company's extensive product line includes essential building blocks like transmitter and receiver components, as well as integrated coherent modules. They also provide advanced switching solutions designed for 400G applications and optical transmission spanning distances from approximately 2 to 2,000 kilometers. A key part of their offering is a diverse range of lasers, including ultra-narrow linewidth tunable lasers, electro-absorptively modulated lasers (EMLs), distributed feedback (DFB) lasers, and various component lasers. They further supply integrated coherent receivers and modulators. NeoPhotonics also produces pluggable coherent transceivers, which ingeniously integrate an ultra-narrow linewidth laser with a coherent receiver and a high-performance coherent modulator. Specific products for data center applications include 100G solutions, alongside multi-cast switching solutions optimized for 100G and higher coherent systems. Beyond components, the company offers broader network products and solutions, such as arrayed waveguide gratings (AWGs), multiplexers, and filters, all vital for dense wavelength division multiplexing (DWDM) systems. Sales are conducted through a direct sales force, targeting network equipment manufacturers. Their market presence extends across North America, Europe, and various Asian regions, including China, Japan, Korea, and Taiwan. Established in 1996 and headquartered in San Jose, California, the company was initially known as NanoGram Corporation before adopting its current name, NeoPhotonics Corporation, in 2002.
