Qorvo launches family of high-speed infrastructure products for next-gen optical networks

At the Optical Fiber Communication conference & exposition (OFC 2015) in Los Angeles (24-26 March), Qorvo Inc of Greensboro, NC and Hillsboro, OR, USA (which provides RF solutions for mobile, infrastructure and aerospace/defense applications) announced the expansion of its portfolio of high-performance optical transport products.

Qorvo is adding new high-speed products for long-haul, metro and data-center applications to deliver new multi-channel and low-power-consumption options that reduce cost, enable market-leading channel-to-channel isolation while shrinking product form factor, and maximize integration and signal fidelity for network equipment manufacturers.

Sampling of devices began in fourth-quarter 2014 to tier-1 and -2 network equipment manufacturers (NEMs) and leading optical module manufacturers. Qorvo says that it has penetrated the data-center market with an initial design-win into equipment used by non-traditional datacoms providers.

Qorvo's newest infrastructure products include dual- and quad-channel limiting and linear drivers that deliver high gain, low power dissipation, high channel-to-channel isolation and low total harmonic distortion (THD). The devices target DP-QPSK and 16QAM, 100G, 200G and 400G applications in module solutions supporting both CFPx and QFSP28 reduced-form-factor (SFF) footprint standards.

"Qorvo products support both limiting and linear transmit and receive through 400G," says James Klein, president of Infrastructure and Defense Products. "Qorvo's newly released portfolio of optical infrastructure products provide the building blocks for next-generation optical networks that require increased bandwidth, higher transmission capacity, and lower cost to the network equipment providers," he adds.  

The new driver portfolio consists of the following products:

  • TGA4960-SL - a 100G CFP2 SMT differential in/out quad-channel linear driver for metro and long-haul applications;
  • TGA4893-SL - a dual-channel SMT driver for 16QAM 200G/400G linear applications;
  • TGA4851-SL - a 100G CFP4 and QSFP28 quad-channel SMT driver for emerging extended-reach data-center applications.

The TGA4960-SL is suitable for CFP2-ACO module form factors and is Qorvo's most advanced quad-channel modulator driver, with what is claimed to be the smallest package in the industry (at 14mm x 8mm x 2.6mm).
Qorvo also recently expanded its optical portfolio to include new 100G limiting and linear transimpedance amplifiers (TIAs) for metro and long-haul applications in both dual- and quad-channel versions. The new products include:

  • TGA4872 - a 100G DP-QPSK dual-linear TIA;
  • TGA4874 - a 100G/400G quad-linear TIA with digital or analog control.

The TGA4874 quad-channel linear TIA features high transimpedance gain, automatic gain/output level control, and a high-bandwidth option for 400G applications. Unique to the industry is the TGA4874, which includes a selectable control interface with either digital or analog control for maximum flexibility for receiver designers.
General availability for the new portfolio of products will begin in second-quarter 2015.
