The interface to the optical cable requires specific physical layer transmitters and receivers to manage signal conversion between the electrical and optical domains. This conversion is normally performed in an optical transceiver module. We provide a family of products that drive optical transmitter devices such as lasers or silicon photonics along with receivers that amplify, reshape, and retime signals from a photodiode. These products are currently offered for bitrates up to 50Gbps. We also offer control and power management products that are optimized for optical module applications to complete the chipset needed in an optical module.
