II-VI launches 400G CFP2-DCO pluggable transceivers for high-speed backbone networks and data-center interconnects
Engineered materials and optoelectronic component maker II-VI Inc of Saxonburg, PA, USA has introduced the 400G CFP2-DCO, its first module to support high-performance 400Gbps coherent transmission in a pluggable form factor for high-speed optical backbone networks and data-center interconnects.
The rapid growth in transmission capacity requirements in optical backbone networks and between hyperscale data centers is driving the demand for next-generation transmission platforms that can scale more economically, with increasing power efficiency, and in smaller form factors. II-VI’s 400G CFP2-DCO is based on the latest generation of 7nm CMOS digital signal processing (DSP) technology that achieves what is said to be the state of the art in power consumption efficiency, in a small pluggable form factor, which enables a pay-as-you-grow deployment model for line-side interfaces. Each module can transport up to 400Gbps of data over a single wavelength using 64GBaud 16QAM modulation and can be tuned to 64 wavelength channels on a 75GHz grid, enabling a total transmission capacity of up to 25.6Tbps over a single fiber.
“This 400G coherent optics module leverages our mature integrated tunable transceiver assembly (ITTRA) coherent optics platform, which has been shipping for over a year,” says Matthias Berger, VP, Coherent Optics business unit. “Our ITTRA is the key reason we expect to become the first in the industry to reach volume manufacturing with such a product.”
For long-haul applications, the module supports 200Gbps transmission employing 64GBaud QPSK modulation, which enables significantly longer reach than existing 200G CFP2-DCO modules that use 32GBaud 16QAM modulation. For networks requiring channels on a 50GHz grid, a 200Gbps mode using 41GBaud 16QAM modulation with enhanced OSNR performance is available. The module can multiplex up to four 100G client signals and supports a mix of IEEE 100G Ethernet and ITU-T Optical Transport Network OTU4 or OTUC (FlexO) host-side interfaces. In addition, IEEE 200G Ethernet, 400G Ethernet as well as ITU-T OTUC2, OTUC3 and OTUC4 host-side interfaces are supported.
The 400G CFP2-DCO is available for sampling and will be generally available in second-half 2020.
