Integrated Coherent Transmitter Receiver optical sub-assemblies
Enabling high-performance optics for coherent networking
Leveraging monolithically integrated indium phosphide (InP) photonic integrated circuits (PICs) and advanced packaging, Nokia Integrated Coherent Transmitter Receiver (ICTR) optical sub-assemblies set industry benchmarks for high-density integration of multiple discrete functions into a single transceiver submodule, including coherent PICs, radio frequency application-specific integrated circuit (RF-ASIC) and thermoelectric cooling.
Nokia’s ICTR optics are designed for easy integration into digital coherent optic (DCO) transceivers or transponder modules and coherent pluggable optics. The assembly consists of a hermetic package containing all the coherent transmit and receive optics with a digital control interface. ICTR optics have built-in memory, a controller and full C-band tunability. Their optical performance is well suited for metro/regional networks in colorless applications.
Benefits and features
High-density integration
- Easy integration into transponder modules or coherent pluggables with a fully integrated optical front end
- Suitable for QSFP-DD, CFP2-DCO and OSFP pluggables packaging
High performance for flexible deployments
- Suitable for metro, regional and long-haul networks
- High transmit power, high transmit OSNR and low out-of-band noise enable deployment across cascaded ROADMs
Reduced cost and power
- High-volume manufacturability
- Low power, compact footprint and high reliability
