Emcore Corp of Albuquerque, NM, USA (which makes components, subsystems and systems for the fiber-optic and solar power markets) has announced the availability of its Optiva satcom band microwave fiber-optic transmitters and receivers for satellite communications, RF antenna remoting and other high-dynamic-range microwave applications.
The new products supplement Emcore's existing Optiva ultra-wideband RF fiber optic transport system by adding band-specific C, X, Ku, or Ka transmitter and receiver modules compatible with the firm's modular or flange-mount Optiva Platform configurations. The addition of the Optiva satcom band RF fiber optic transport system further expands the existing Optiva platform that already supports 50MHz to 18, 22 or 40GHz broadband microwave transport, reference oscillators, IRIG, IF, L- & S-band, plus audio, video, data and ethernet.
"By leveraging our existing ultra-wideband 50MHz-40GHz Optiva products as building blocks, Emcore is able to provide high-performance externally modulated RF-banded technology at directly modulated technology price points. Additionally, these new products support multiple format frequency transport in a single flexible platform for C, X, Ku, and Ka-band applications." says Frank Weiss, VP of Emcore's Advanced Systems Division.
Utilizing the firm's high-performance ultra-low Relative Intensity Noise (RIN) source laser technology and high-optical-input-power-capable photodiodes, the new system provides a high dynamic range of > 110dB-Hz2/3. The system features microprocessor-based transmitter and receiver control for laser and modulator bias, plus variable RF link gain which provides consistent high-performance and constant gain operation.
The standard Optiva transmitter provides a high-power optical output and operates at a nominal wavelength of 1550nm. Wavelength selected lasers on the ITU grid are also available to support multi-channel DWDM applications. Additional advanced capabilities include Simple Network Management Protocol (SNMP) V.1, optical and RF amplification options, and RS-232 monitor & control with flexible user interface options.
