Emcore launches Medallion 8100 series DOCSIS 3.1 1550nm CATV transmitter and unveils linear externally modulated laser technology

In booth #10.2/E39 at ANGACOM 2016 Exhibition & Congress for Broadband, Cable and Satellite in Cologne, Germany (7–9 June), Emcore Corp of Alhambra, CA, USA – which provides indium phosphide (InP)-based optical chips, components, subsystems and systems for the broadband and specialty fiber-optics markets – is launching the Medallion 8100 series DOCSIS 3.1, L-EML 1550nm externally modulated CATV transmitter.

The Medallion 8100 series leverages the L-EML (Linear Externally Modulated Laser), which was invented, developed and manufactured exclusively at Emcore. The L-EML consists of a high-power, low-noise, narrow-linewidth laser combined with a proprietary highly linearized modulator in a monolithic assembly. It enables long-distance optical link performance approaching traditional lithium niobate-based externally modulated transmitters, but is more cost-effective for its targeted applications and far exceeds the performance of distributed feedback (DFB)-based systems, claims Emcore.

To accommodate a broad range of network architectures, the Medallion 8100 series provides options, including P-type, C-type, T-type and R-type transmitters. The P-type transmitters offer a high-performance solution for applications where the simultaneous transport of CATV and satellite intermediate frequency (SAT-IF) signals are required. The SAT-IF signals can be applied anywhere in the 950-3500MHz band.

The C-type and T-type series transmitters are for use in node-splitting architectures requiring cost-effective dense wavelength division multiplexing (DWDM) transmission over medium-length fiber distances. They are easily configured to meet most hybrid fiber coaxial (HFC) networks requiring link lengths from 0 to 65km with one erbium-doped fiber amplifier (EDFA) as well as links utilizing multiple EDFAs.

The R-type series transmitters are designed for fiber-to-the-premise (FTTP) and radio frequency over glass (RFoG) architectures requiring high-quality transmission over varying transmission lengths and EDFA output powers. These transmitters support very high optical launch powers while controlling the detrimental effects of stimulated Brillouin scattering (SBS), group velocity dispersion (GVD), and self-phase modulation (SPM).

"The Medallion 8100 series of rack-mount CATV transmitters ushers in a new era of transmission technology for the industry," says senior product line director Grant Olecko. "With the rapid adoption of next-generation DOCSIS 3.1 deployments throughout the world, Emcore recognized the need for a cost-effective solution that overcomes the technical limitations of linear DFBs, while pushing the boundaries of performance towards traditional, but higher-cost, lithium niobate-based solutions," he adds.

At ANGACOM, Emcore is showcasing its full system-level portfolio for CATV, including the new Medallion 6100 series transmitters, the Medallion 8000 series of directly modulated transmitters, the new Medallion 7110 series of low-noise, high-power EDFAs, and the Medallion 2100 series of optical switches. Emcore is also featuring its full line of DFB butterfly lasers, DOCSIS 3.1 lasers, TO-56 lasers, low-noise optical receivers, broadband photodiodes and components for wireless and distributed antenna system (DAS) applications.
