ALBUQUERQUE, N.M., July 29, 2013 (GLOBE NEWSWIRE) -- EMCORE Corporation (Nasdaq:EMKR), a leading provider of compound semiconductor-based components and subsystems for the fiber optics and space solar power markets, announced today the launch of the Medallion 8000 Series 1550 nm Directly-Modulated DWDM Cable Television (CATV) Transmitter.
The Medallion 8000 is the latest addition to EMCORE's 1550 nm CATV fiber optic transmitter portfolio and is designed for wideband applications that require both CATV and Satellite-Intermediate Frequency (SAT-IF) signals to be transmitted over fiber lengths up to 30 km. This facilitates network designs that use a single transmitter to carry multiple signals, while lowering costs, system complexity and rack space requirements.
The Medallion 8000 supports 79-channel NTSC analog signals and/or a combination of Quadrature Amplitude Modulation (QAM
) and SAT-IF signals with a reduced number of CATV analog channels. It features fixed fiber length options of 0 – 10 km, 5 – 15 km, 10 – 20 km and 15 – 25 km with a maximum of 18 dBm Stimulated Brillouin Scattering (SBS) suppression, and is also available with a selectable fiber length option. The selectable fiber length option allows the user to set the Medallion 8000 for best optimized CSO (Composite Second Order) distortions at any fiber length from 0 – 30 km in 1 km increments and has a maximum SBS suppression of 20 dBm.
The Medallion 8000 family of transmitter products is designed to support various CATV transmitter applications with a common platform. A 75 ohm CATV RF video input supports frequencies up to 1002 MHz. Design features including low chirp control, noise suppression circuitry, and patented pre-distortion technology that provides outstanding performance with EMCORE'S wide range of cooled broadband directly-modulated lasers. A second 75 ohm RF input supports frequencies up to 2700 MHz for FTTP (Fiber-To-The-Premises), SAT-IF, and wireless applications.
