Emcore shipping Optiva Q/V-band fiber-optic links

Emcore Corp of Alhambra, CA, USA – which provides mixed-signal products for the aerospace & defense and broadband communications markets – is now shipping its Optiva Q/V-band fiber-optic links for applications from 2MHz to 60GHz.

Introduced at Satellite 2020 in Washington DC in mid-March, the transmitter and receiver modules are suitable for antenna remoting, interfacility links, electronic warfare systems, broadband delay lines, signal processing systems and other high-dynamic-range applications.

Optiva Q/V-band unamplified microwave fiber-optic transmitter and receiver pairs are said to eliminate the performance and cost penalty of block up/down-conversion. At the heart of the system is Emcore’s high-performance, ultra-low RIN (relative intensity noise) source laser technology combined with high optical input power capable photodiodes. Optiva Q/V-band links feature microprocessor-based transmitter control for laser and modulator bias, along with link gain for consistent high-performance, low-bias operation and higher SFDR (spurious-free dynamic range) of >102dB-Hz2/3 at 60GHz.

“Emcore is the only major fiber-optic transmission equipment supplier producing native Q/V-band-capable fiber-optic links,” says David Wojciechowski, VP & general manager of Defense Optoelectronics. “Our products deliver a major improvement in cost and performance compared to currently available solutions with a simplified communications architecture, fewer points of failure, and increased overall uptime for these extreme high-frequency applications,” he claims.

“Our Optiva Q/V-band fiber-optic links represent a significant breakthrough in microwave transmission technology,” reckons Defense Optoelectronics product line manager Nan Wang. “By leveraging our advanced engineering capabilities and vertically integrated manufacturing facility, Emcore provides cutting-edge, high-performance fiber-optic transmitter and receiver products demanded by our customers.”

Optiva Q/V-band fiber-optic links are SNMP compliant with DWDM operation that increases transport capacity without increasing fiber count. They can be housed in the same chassis and monitored by the same NMS (network management system) as other Optiva cards, enabling a full redundancy system in a single chassis.
