Microchip and Acacia link to support bandwith growth

Thu, Oct 07, 2021

Data Centre Interconnect (DCI) and metro optical transport network (OTN) platforms are transitioning from 100/200G to 400G pluggable coherent optical modules to support bandwidth growth driven by the expansion of data centres and 5G network buildouts. Microchip Technology and Acacia, part of Cisco, are supporting this transition by bringing to market interoperable solution sets consisting of Microchip’s DIGI-G5 OTN processor and META-DX1 terabit secured-Ethernet PHY and Acacia’s 400G pluggable coherent optics.

The aim of the collaboration is to establish an ecosystem to support 400G CFP2-DCO, QSFP-DD and OSFP modules for the 400ZR specification as well as the OpenZR+ and Open ROADM multi-source agreement (MSA) applications.

For converged packet/OTN optical platforms, Microchip’s DIGI-G5 and Acacia’s 400G CFP2-DCO module are designed to enable terabit-class OTN switching line cards, muxponders, and switchponders. The DIGI-G5 interoperates with Acacia’s 400G CFP2-DCO module using a Flexible OTN (FlexO) or NxOTU4 interface to efficiently support OTN traffic, including Open ROADM MSA interface modes and 200G/400G ITU-T standards currently being drafted.

For compact modular optical systems, Microchip’s META-DX1 and Acacia’s 400ZR and OpenZR+ modules are designed to enable 400G flexible line rate muxponders/transponders with support for multiple client optics types including QSFP28, QSFP-DD, and OSFP modules, helping service providers to transition from 100 GbE to 400 GbE using the same hardware.

For data centre routing and switching platforms, Microchip’s META-DX1 and Acacia’s 400ZR and OpenZR+ modules are designed to enable dense 400 GbE or FlexE with per port MACsec encryption coherent line cards. This helps customers leverage IP routers/switches over DWDM (IPoDWDM) infrastructure in DCI deployments.

“DIGI-G5 and META-DX1 have enabled our optical transport, IP routing and Ethernet switching customers to implement a new class of multi-terabit OTN switching and high-density 100/400 GbE and FlexE line cards that deliver on stringent packet timing and integrated security capabilities for the build out of cloud and carrier 5G-ready optical networks,” said Babak Samimi, vice-president for Microchip’s communications business unit. “Our interoperability efforts with Acacia help to demonstrate that an ecosystem for volume deployment of these new line cards with pluggable 400G coherent optics exists.”

“With Acacia’s 400G coherent modules verified to interoperate with Microchip’s DIGI-G5 and META-DX1 devices, we see it as a robust solution designed to address network capacity growth and improved efficiency,” said Markus Weber, senior director DSP, product line management of Acacia, now part of Cisco. “The compact size and power efficiency of our 400G OpenZR+ CFP2-DCO modules were designed to help network operators deploy and scale capacity of high-bandwidth DWDM connectivity between data centres and in metro networks.”

ST and Rosenberger unite to develop high-speed contactless connector based on 60GHz wireless technology

Wed, Oct 06, 2021

STMicroelectronics and Rosenberger, a leading manufacturer of impedance-controlled and optical connectivity solutions, are to collaborate on a contactless connector for ultra-reliable, short-range, point-to-point full-duplex data exchanges in industrial and medical applications.

Rosenberger’s RoProxCon, leverages ST’s 60GHz RF transceiver, the ST60A2, to deliver high-speed data transmission while providing immunity to movement, vibration, rotation and contaminants such as moisture and dust, which can disrupt conventional pin-and-receptacle interconnects.

The STMicroelectronics ST60A2 offers reliable, point-to-point, high-data-rate transmission of up to 6.25 Gbps over distances of a few centimetres at low power. The new connector will suit applications in smart factories, medical technology, connected devices, office equipment, conveyer technology and renewable energies.

Operating over an extended temperature range of -40 to +105 degrees C, the chip ST60A2 is suited to industrial markets. With a 2.2 x 2.2 mm package footprint, the chip offers an ultra-low power consumption of 70mW for a reliable, completely contactless link.

“Pairing ST’s contactless connectivity technology with our interconnect expertise and antenna-design knowledge enabled us to create a first-of-its-kind module that transmits full duplex data at up to 6 Gbps with complete rotational freedom,” said Folke Michelmann, executive vice-president medical and industries at Rosenberger.

“In working with ST, we see limitless application possibilities for our connector, which provides high-reliability and high-throughput at low power.”

R&S FSPN offers dedicated phase noise analysis and VCO testing

Wed, Oct 06, 2021

For high speed, real-time phase noise measurements using sources that require high stability in demanding applications, the new R&S FSPN phase noise analyser and VCO from Rohde & Schwarz offers sensitivity, accuracy and reliability.

Rohde & Schwarz designed the new R&S FSPN phase noise analyser and VCO tester for production and design engineers who characterise sources such as synthesizers, VCOs, OCXOs, and DROs. Providing high sensitivity and measurement speed, the R&S FSPN suits demanding phase noise and VCO analysis in development and production.

The R&S FSPN comes in two models, one covers the frequency range from 1 MHz to 8 GHz and the other from1 MHz to 26.5 GHz, addressing radar and satellite applications in the C band, X band, Ku band, and the complete K band.

Catering to measurement challenges in these fields, the R&S FSPN expands the Rohde & Schwarz phase noise product portfolio which already contains the R&S FSWP phase noise spectrum and signal analyser.

The R&S FSPN shares R&S FSWP features such as low noise internal local oscillators coupled with real-time cross correlation engines for increased measurement sensitivity.

Cross-correlation sensitivity gains can be viewed in real-time in result traces, allowing users to adjust the trade-off between measurement speed and sensitivity to meet their application requirements.

Users in production need just a few correlations to measure high-quality oscillators, synthesizers or VCOs with high throughput. By increasing the number of correlations, users in research and development can characterise the most sensitive commercially available synthesisers and oscillators. Simultaneous device frequency and phase settling times can be measured with up to 8 GHz of real-time analysis bandwidth.

To investigate oscillator long-term frequency stability, the R&S FSPN calculates the Allan variance in the time domain at fixed intervals and uses phase noise measurements to apply cross-correlations and suppress spurs.

The analyser is also equipped with three ultra-low-noise DC sources to supply and sweep VCOs. The built-in VCO characterisation measurement mode analyses VCO characteristics such as frequency, sensitivity, RF power or current draw versus tuning voltage.
