At the Satellite 2014 event in Washington DC (16-19 March), Emcore Corp of Albuquerque, NM, USA, which makes compound semiconductor-based components and subsystems for the fiber-optic and solar power markets, has introduced the Optiva OTS-2L10, 10MHz/L-band fiber-optic links for very small aperture antenna (VSAT) signal transport.
VSAT systems provide high-speed, broadband satellite communications for internet or private network communications and suit remote internet connectivity, video transmission, VoIP and emergency back-up communications. VSAT can connect remote offices, media vans or other remote locations to send or receive data.
The OTS-2L10 fiber-optic links are optimized to provide transparent, simultaneous 10MHz and L-band signal transport. They provides isolation of the 10MHz from L-band signals at the transmitter and receiver with very low phase noise, facilitating greater flexibility to locate VSAT antennas for optimum performance. All the connectivity features of coaxial cable are maximized without the penalty of RF loss, allowing the system to dictate the location of the equipment and not the limitations of the coaxial cable.
The OTS-2L10 is designed with optically isolated uncooled distributed feedback (DFB) lasers that enable high-dynamic-range links with fixed gain up to 10km. Connection is via 50 Ohm SMA and the OTS-2L10 includes receiver DC output for the BUC upconverter with transmitter and receiver RF power monitoring via LED and SNMP (Simple Network Management Protocol).
“The Optiva 10MHz/L-band system is unique in its ability to simultaneously transport the 10MHz and L-band signals while keeping them isolated with the low phase noise,” says Frank Weiss, VP of Advanced Systems. “This allows customers to optimize placement of their VSAT antennas for the best performance and minimal RF loss,” he adds.
OTS-2L10, 10MHz/L-band fiber-optic links fit in Optiva 16, 6- and 2-slot enclosures which support Daisy Chain video, audio, and data links. They are CE & CSA certified and RoHS compliant.
