II-VI Inc announces Optical Line Subsystem platform for data-center interconnects
Engineered materials and optoelectronic component maker II-VI Inc of Saxonburg, PA, USA has launched its Optical Line Subsystem platform for data-center interconnects (DCI), which is optimized for direct-detect DWDM transceivers, including the new COLORZ-Lite 100G PAM4 (4-level pulse amplitude modulation) based on the COLORZ silicon photonics platform from Inphi Corp of Santa Clara, CA, USA (a provider of high-speed mixed-signal ICs for communications, computing and data-center markets).
Cloud service providers require increasingly scalable, cost-effective and power-efficient solutions to meet the rapidly growing demand for DCI. II-VI’s Optical Line Subsystem multiplexes, amplifies and demultiplexes multiple wavelengths of COLORZ-Lite data streams to achieve a combined transmission rate of up to 4Tb/s over a 20km reach in a compact one-rack-unit (1RU) form factor. II-VI says that this capability offers cloud service providers and enterprise customers a cost-optimized direct-detect DWDM solution for these distances.
“The COLORZ-Lite direct-detect DWDM technology enables cloud service providers to alleviate fiber exhaust resulting from the high usage of 100G grey optics,” says Dr Loi Nguyen, founder, senior VP, Optical Interconnect, at Inphi. “The key to achieving this is the II-VI Optical Line Subsystem technology, which enables the transport of direct-detect data streams at significantly lower cost points than any other competing solution,” he comments.
“We have been working closely with Inphi to design from the ground up a disaggregated Optical Line Subsystem that delivers disruptive performance at a low cost,” says Dr Sanjai Parthasarathi, VP, product marketing & strategy, of II-VI’s Optical Communications Group. “We are uniquely positioned to deliver this high-value solution due to our vertically integrated technology and market leadership in optical amplification, wavelength multiplexing and demultiplexing, tunable dispersion compensation, optical channel monitoring and fiber integrity monitoring,” he reckons.
At the European Conference on Optical Communications (ECOC 2017) in Gothenburg, Sweden (18-20 September), II-VI’s Optical Line Subsystem and Inphi’s COLORZ-Lite 100G PAM4 platforms are being jointly demonstrated in Inphi’s booth #337.
In booth #252, II-VI is showcasing new products driven by advances in its materials and technology platforms. The product showcase includes subsystems solutions, highly compact optical amplifier solutions tailored to enable high-bit-rate DWDM transceivers, embedded monitoring solutions for transport networks, as well as key devices and sub-assemblies for data-center transceivers.
