MaxLinear launches low-power driver and TIA for 100G modules
Carlsbad company MaxLinear, a provider of radio frequency and mixed-signal integrated circuits, has launched two new products designed for low-power 100G optical transceiver modules.
ADVA launches MicroMux module
ADVA Optical Networking unveiled its new MicroMux module, the latest addition to its FSP 3000 CloudConnect platform. The module provides unprecedented client port flexibility for data centre interconnect (DCI) applications without compromising on power, space or spectral efficiency. Christoph Glingener, CTO, ADVA Optical Networking, commented: ‘Our MicroMux module is an entirely unique device that drives our DCI solution even further ahead of the field. With one single QSFP28 module, customers are now able to convert a 100GbE client port into either 10 x 10GbE ports or 2 x 40GbE ports. What’s more, it can be done without any detriment to the incredible data or power density of our FSP 3000 CloudConnect platform. This is unmatched in the industry.’
This capability is key for internet content
providers and cloud service providers that need DCI infrastructure that can both support current service demands and effectively scale for future growth. Until now, this has been a difficult balancing act that often led to inefficient use of
IQ Transmitter from ID Photonics now supports 64GBd applications
German test and measurement provider has increased the bandwidth of its IQ Multi-Format Transmitter RF to more than 40GHz. This allows researchers and engineers to evaluate designs for coherent optical signals modulated with symbol rates up to 64GBd.
The IQ Multi-Format Transmitter is an integrated laboratory optical transmitter developed through a partnership with the Fraunhofer Heinrich-Hertz- Institute. When partnered with an arbitrary waveform generator such as Keysight’s M819 AWG portfolio,
space, power and, ultimately, inflated operating costs. With the flexibility provided by the new
MicroMux module, content and service providers now have access to one DCI solution that meets all of their legacy needs and future demands. What’s more, the ADVA FSP 3000 CloudConnect platform is still the only open optical line system on the market and the only one that supports all the industry’s open protocols, according to the company.
The new ADVA MicroMux module is available in both singlemode and multimode versions, to support data over short reach, intermediate reach (40GbE) and long reach (10GbE) connections. This is a key feature request from content and service providers as today’s data centres contain both singlemode and multimode fibre. The flexibility also extends to the mixing of client ports. Customers can seamlessly mix 10GbE, 40GbE and 100GbE clients into the ADVA FSP 3000 CloudConnect’s single 400Gb/s line card without any footprint increase – another vendor first, the company claims.

The MxL2025 is a quad-channel externally modulated-laser (EML) driver with an attractive combination of low power dissipation and high performance. The MxL2025 supports both emerging 100Gb/s client-side telecom module designs and modules being developed for data centre networks. The MxL2025 features a per-channel data rate of 28.3GBd with a low, 200mW power dissipation per channel, making it an ideal fit for CFP, CFP2 and CFP4 100G pluggable optical modules that support the 100GBASE- ER4, 100GBASE-ER4-Lite and 100GBASE- LR4 networking standards. The device features output crossing-point and output amplitude control. It also has an integrated bias tee to maintain optimal power dissipation. The second product, the MxL9101, is a 28Gb/s transimpedance amplifier (TIA) array designed for use in receive modules of 100 Gigabit Ethernet optical transceivers. The device is a high dynamic range, four-channel 28Gb/s TIA with a die size of 3.2mm x 1.6mm. The device features best-in-industry sensitivity and overload for robust signal reception in SR4/PSM4/CLR4/LR4 applications. When combined with an avalanche photodiode (APD), the receiver can also support ER4-lite applications. The TIA features the industry’s lowest power dissipation of 0.32W and adjustable bandwidth control. All of these features make the part ideal for small form-factor pluggable transceivers including CFP, CFP2, CFP4 and QSFP28 form factors.

it enables the generation of high-speed coherent optical signals. The unit converts four RF waveforms from the AWG into a dual-polarisation IQ modulated optical signal. The unit features pattern independent automatic bias control that can optimise performance irrespective of modulation formats. This allows researchers to change modulation formats and symbol rates while maintaining the modulator’s bias stability. This helps to speed up automated impairment and stress testing cycles. ‘The significant bandwidth enhancement of our multi-format transmitter allows researchers to unleash
the full potential of latest arbitrary waveform generator instruments available,’ said David Stahl, general manager of ID Photonics. ‘High-fidelity constellations at up to 64GBd can only be achieved if proper matching of both electrical signal source and electro- optical converter is achieved. By providing calibration files that can be seamlessly integrated into Keysight’s latest AWG product line, we have the unique capability to generate these high fidelity signals.’ The IQ Multi-Format Transmitter is available in several configurations, including full dual polarisation, emulated dual polarisation and single polarisation.
