The Lumentum CFP2-DCO is part of a series of coherent module solutions based on the Lumentum patented photonic integrated circuit (PIC) platform, which enables cloud operators and carriers to create optical interconnects with much greater capacity and density with reduced complexity in the high-capacity dense wavelength division multiplex (DWDM) optical networks used in hyper-scale cloud and telecom infrastructure applications. Lumentum CFP2-DCO module incorporates several coherent solutions from Lumentum in a pluggable module, including its new extended-tuning-range ultra-narrow-linewidth tunable C++ LASER Nano-ITLA (integrated tunable laser assembly). It also features its high-bandwidth 64Gbaud C++ ICR Receiver and C++ CDM Modulator. This module supports tuning across the full Super C-band and is said to provide up to 50% more spectrum and resulting capacity than standard modules.

This CFP2-DCO module tunes to 75GHz-spaced wavelength channels when operating at 64Gbaud and 16 QAM to support 400G transmission in 400ZR and 400ZR+ modes for cloud data-center interconnect (DCI) and metro telecom applications. For long-haul and regional applications, the CFP2-DCO module utilizes 64Gbaud and QPSK modulation to deliver 200G-per-wavelength transmission. If the application requires that a 50GHz channel wavelength spacing be used, this CFP2-DCO module can tune over 120 channels.

The module is compliant with the OIF-CFP2-DCO-01.0-Implementation Agreement and has a superior optical signal-to-noise ratio (OSNR) and watt per gigabit performance. The module will also be available in standard C-band tuning range for applications that do not require the significantly higher capacity per fiber that this module enables.
