Integrated Coherent Transmitter Receiver optical sub-assemblies

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.
