Emcore introducing 1.8GHz-bandwidth cable broadband transmission capability at ANGACOM
At the ANGACOM 2019 Exhibition & Congress for Broadband, Cable and Satellite at the Cologne Congress Center, Germany (4-6 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 introducing 1.8GHz-bandwidth plans for linear fiber-optic HFC (hybrid fiber coaxial) networks.
Emcore says that 1.8GHz builds on the foundation of its ongoing advancements in 1.2GHz systems where its forward-path CATV transmitters utilizing linear externally modulated laser (L-EML) technology can now achieve 46dB MER (modulation error ratio) with full quadrature amplitude modulation (QAM) loading up to 40km. Emcore says that its L-EML-based transmitters continue to receive wide acceptance with major cable broadband service providers and are available in a rack-mountable 1RU form factor, or a PCBA (printed circuit board assembly) mini-transmitter subassembly enabling systems designers to quickly integrate the L-EML device technology into a variety of CATV transmitter platforms.
“With 1.8GHz capability, Emcore continues its leadership in advancing the network performance cable broadband service providers can deliver to their customers,” says senior product director Grant Olecko. “Cable service providers can future-proof their systems with up to a 50% increase in network capacity with no change to existing architecture,” he adds.
At ANGACOM, Emcore is also showcasing its MEDALLION series portfolio of end-to-end CATV rackmount transmission systems featuring the 8100 DOCSIS 3.1, L-EML 1550nm CATV transmitter along with MEDALLION 7100 and 7110 high-power CATV fiber amplifiers and MEDALLION 2100 optical A/B switch. In addition, Emcore is displaying the new Model 3644 mini-Tx 1.2GHz, 1550nm L-EML CATV transmitter subassembly designed for a range of CATV applications to 40km and beyond.
