Finisar introduced a new product family, complementing its line of coherent components and ACO (Analog Coherent Optics) transceivers. This family, called the Integrated Tunable Transmitter and Receiver Assembly (ITTRA), is the industry’s smallest fully integrated coherent optics assembly. It is designed for easy customer integration into coherent line cards or DCO (Digital Coherent Optics) transceivers, enabling customers to accelerate their time to market and reduce program and development costs. In a footprint that is 70% smaller than the size of a CFP2 module, the ITTRA provides the same functionality as a CFP2-ACO. All key building blocks of an ACO interface (tunable laser, optical amplifier, modulators, drivers, coherent mixer, photodiode array, and TIAs) are incorporated in a single optical sub-assembly, which is combined with a miniature controller board that provides customers a standardized management interface. Since the ITTRA is a fully calibrated and tested assembly instead of a disaggregate set of components, it yields operational cost savings for the line card or module integrator because test times of the end product are greatly reduced. The demonstration at OFC 2018 shows the 32Gbaud ITTRA transmitting and receiving data at 200 Gb/s using DP-16QAM modulation. The product will be sampling in the second quarter of 2018.
