ECOC 2018: NeoPhotonics shows 400G EML and silicon photonics

At ECOC 2018 this week in Rome, NeoPhotonics is showing its suite of lasers and analog ICs for uncooled, non-hermetic single laser 100G and 4 laser 400G links within data centers.    The product suite includes Electro-Absorptively Modulated Lasers (EML) for 2 km PAM4 based links and high power CW laser sources for 0.5 and 2 km Silicon Photonics-based links, along with the photodetectors, drivers and trans-impedance amplifiers required.

NeoPhotonics anticipates a technology shift to single-laser (lambda) 100Gbps and 4-laser (lambda) 400Gbps using 4 level pulse amplitude modulation (PAM4) driven by demand for higher port density and lower cost per bit for optical connections inside the data center.

The 100G/400G Component Suite from NeoPhotonics includes:

  • 53GBaud Uncooled CWDM4 EML, which includes the option for integration with NeoPhotonics’ open drain driver. With an uncooled operating temperature range from 20 to 70C and the capability to operate reliably in “open-air” transceiver designs, thus eliminating hermetic enclosures, this EML is a preferred transmitter solution for PAM4 based FR4 2 km data center applications. Versions are also available at 1310 nm for DR1 and DR4 500 meter applications.
  • 53GBaud Open Drain Driver (ODD) for linear operation of EML lasers. With a typical 90mW of power consumption per channel and small size, this high speed driver can be co-packaged with the EML reducing power and increasing linearity and is well suited for use in small form factor pluggable modules.
  • 53GBaud PIN photodetectors. The side illumination structure of the PIN PD enables a simple coplanar assembly with a mux/demux chip and TIA and is well suited for compact modules.
  • 53GBaud Transimpedance Amplifier (TIA). With low noise and a typical power consumption of 60mA over a 3.3V rail, this TIA is well suited for receiver signal amplification for up to 10km transmission.

In addition, transceiver developers have also begun deployment of silicon photonics based transceivers for industry standard MSAs such as CWDM4, CLR4 and PSM-4, which has led to the need for custom, high power and non-hermetic laser sources to drive these transceivers. To support this emerging Silicon Photonics eco-system, NeoPhotonics has developed and qualified a line of high power, uncooled lasers and laser arrays for several industry leading Silicon Photonics transceiver manufacturers, as well as offering single and quad drivers for Silicon Photonics modulators:

  • High Power 40mW and 70mW non-Hermetic CW Laser Sources for Silicon Photonics based CWDM4 FR4 and 1310nm DR1 and DR4 Applications. These efficient, high power DFB lasers can operate up to 75 deg. C and have completed the non-hermetic testing compliant with the Telcordia GR-468-CORE, making them well suited for use in non-hermetic Silicon Photonics based small form factor pluggable modules.
  • 53GBaud Quad MZM drivers for Silicon Photonics modulators. This quad driver has a high 3.5Vppd output per channel and a typical 2.2W low power consumption for all four channels designed for small form factor pluggable modules.  This component is also available in single driver configurations for DR1 applications.

“Our complete suite of 53GBaud Linear Optical Components provides all needed optical components for single laser 100Gbps transmitters and receivers, scalable to 400Gbps transceivers with CWDM4 wavelengths,” said Tim Jenks, Chairman and CEO of NeoPhotonics.  “Furthermore, our uncooled, high power CW DFB lasers and laser arrays are critical elements for any 100G, 200G or 400G Silicon Photonics based transceiver.  We are pleased to offer the lasers and critical analog electrical components for both next generation data center transceiver approaches,” continued Mr. Jenks.

ECOC 2018: NeoPhotonics cites progress with 64 GBaud for 600G

At ECOC 2018L NeoPhotonics is reporting that its suite of 64 GBaud optical components for coherent systems are currently being used by multiple major customers to develop systems with 600G per wavelength transport capacity.   64 GBaud components double the symbol rate over standard 100G (32 GBaud) coherent systems.

NeoPhotonics' suite consists of three components:

  • 64 GBaud CDM:  NeoPhotonics 64 GBaud, polarization multiplexed, quadrature coherent driver modulator (CDM) is shipping in limited availability and features a co-packaged InP modulator with a linear, high bandwidth, differential driver in a compact package designed to be compliant with the anticipated OIF Implementation Agreement.
  • 64 GBaud Micro-ICR:  NeoPhotonics Class 40 High Bandwidth Micro-Intradyne Coherent Receiver (Micro-ICR) is in volume production and is designed for 64 GBaud symbol rates, doubling the bandwidth of standard 100G ICRs. The compact package is designed to be compliant with the OIF Implementation Agreement OIF-DPC-MRX-02.0.
  • Low Profile Micro-TL:  NeoPhotonics ultra-narrow linewidth external cavity tunable laser features very low phase noise and power consumption and has been proven in volume production. It is now configured in a smaller, lower profile package that is compliant with the OIF Implementation Agreement OIF-MicroITLA-01.

These components work together to enable customers to implement single wavelength 600G or dual wavelength 1.2T data transmission over data center interconnect (DCI) distances of 80 km. 

“We are working closely with customers to provide a matched suite of high speed optical components for 600G per wavelength to enhance system performance and reduce time to market,” said Tim Jenks, Chairman and CEO of NeoPhotonics.  “With our next generation highly integrated COSA, operating at 64 Gbaud and beyond, and our Nano-Tunable Laser, we are working to enable highly compact pluggable 400G modules,” continued Mr. Jenks.

The company says three OEM customers have elected to use all three of these components in their development, while additional customers have elected to use a subset of the NeoPhotonics 64 GBaud coherent component suite.  The components also support 400G over metro distances of 400-600 km using 64 GBaud and 16 QAM or 200G over long-haul distances of greater than 1000 km using 64 GBaud and QPSK.

In addition, at 16:10 pm on Tuesday, September 25th Dr. Winston Way, NeoPhotonics’ CTO Systems, will present a paper entitled “Next-Generation Coherent Pluggable Transceivers in a CDC ROADM Based Optical Network” at the ECOC 2018 Exhibition Market Focus session entitled: “Optical Network Agility/Software Defined Networks.”

ECOC 2018: 5G requires fiber network infrastructure - Source Photonics

There may be a vast number of opportunities for mobile fronthaul and backhaul on the horizon but improvements in protocols, standards and technology will also need to be made, according to Supriyo Dey, Senior Director Product Line Management at Source Photonics, speaking on the opening day of the ECOC 2018 Exhibition, taking place in Rome, Italy.

Dey commented: “While an exciting era of unprecedented opportunity is almost here in the shape of 5G, it comes with a set of challenges for the whole industry. The advent of this technology is undeniably huge, but there’s a real challenge for those who are hungry to develop its capabilities to match their expectations in terms of performance. Applications such as 3D video, augmented reality, UHD screens, self-driving cars and smart cities to name a few will need to be supported by mobile front and backhaul.

“With these advances in capabilities come new requirements -, up to 10Gb/s data rate to support high quality video, ultra-reliable and low latency communication for autonomous vehicles and massive node communications for them Internet of things.

“The current 4G optical fronthaul and backhaul architecture will not be adequate to support these new applications. While several optical fronthaul and backhaul solutions have been proposed, we have yet to see a clear winner.”

Dey’s observations were delivered at the ECOC18 Exhibition’s Market Focus, as part of an agenda that tackled topics ranging from FTTX evolution and next-generation data centers to optics as an enabler for 5G.

Source Photonics is also showcasing some of its latest products at the exhibition in the form of live demos.

This includes a demonstration with equipment testing experts Ixia, of its 400G QSFP-DD LR8 transceiver. In addition, the company will also demonstrate its 25G SFP28 LR Lite which supports CPRI wireless and 25GBASE-LR applications.

ECOC 2018: IDT debuts100G Single Lambda EML driver and TIA for 200G/400G

At ECOC 2018, Integrated Device Technology (IDT) is introducing its latest single lambda EML driver and TIA for 200G/400G datacenter applications.

IDT said its 400GbE based on 100G single lambda designs will establish an ecosystem to lower the cost per bit, a key enabler for scalable Switch-to-Switch and Switch-to-Server Optical Links, supported with small form factor modules, such as 200G/400G QSFP-DD, OSFP and 400G OBO. The Electro-Absorption Modulated Laser (EML) and Trans-Impedance Amplifier (TIA) are key analog IC components, and the features of IDT's chip set of high bandwidth, high sensitivity and low power consumption are promising to support those modules.

The IDT 100G single lambda EML Driver is available as a die (HXT45100) and as a packaged driver (HXT45x01) with 1 or 4 channels. The driver family features broad bandwidth, high linearity and low power consumption for the QSFP-DD module form factor. The SMT-type packaged drivers integrate built-in Bias-T, internal high-frequency chokes and input DC blocks, and offers 2Vpp output voltage swing while consuming less than 300mW per channel power.  The bandwidth is over 40GHz with excellent phase flatness and channel isolation.

The 100G single lambda TIA, offered as 1 channel and 4 channel dies (HXR45x00),  provides under 5kohm transimpedance gain, 500mVpp maximum differential output voltage, excellent flat frequency response and low group delay with 3dB bandwidth higher than 36GHz, is very suitable for 100G single lambda applications, with a power dissipation as low as 168mW per channel. The HXR45x00 is configurable by I2C, for 28G applications, with a flat frequency response and 3dB bandwidth of 25GHz and reduced power dissipation down to 135mWper channel.

"We are very excited of the initial results of our single channel and four channel 112G/ch TIA," said Andrea Betti-Berutto, IDT Fellow. "This new generation of TIAs will well satisfy the high performance challenges required for 100G single lambda applications and simultaneously consume very little power and deliver a high sensitivity solution for lower rate applications, such as 28Gbaud-based small form factor modules."
