Emcore shipping Optiva next-gen L-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 OTS-1LNG Next-Gen L-band fiber-optic links featuring extended bandwidth for native S- and C-band. The new transmitter and receiver modules for the Optiva Platform are suitable for satellite antenna signal transport and interfacility link applications.
Optiva Next-Gen L-band fiber-optic transmitter (Tx) and receiver (Rx) pairs are said to be a cost-efficient design using Emcore’s latest high-speed uncooled DFB (distributed feedback) laser technology. With capability up to 6GHz covering S- and C-band, they enable users to future-proof their systems with better performance at a lower cost than competing alternatives, claims the firm. The native C-band coverage also provides an optimal solution for 5G C-band interference, it adds.
The Optiva platform enables long-distance fiber-optic links over 100km with 1/10th the size and weight of coaxial cable. Fiber is much less expensive than coaxial cable over any reasonable distance, and the ability to keep the signal in the native satellite frequency reduces signal errors caused by up- and down-conversion. Fiber also provides greater immunity from electromagnetic interference (EMI), hum and distortion of the signal.
“Our Optiva Next-Gen L-band fiber-optic links present a very high-value proposition to our customers, with the extended bandwidth capability to native S- and C-band providing a major improvement in performance at a lower cost than our previous generation,” says David Wojciechowski, VP & general manager of Defense Optoelectronics. “Our latest Optiva products have a simplified communications architecture, resulting in reduced network complexity with lower maintenance cost and increased overall up-time compared to currently available solutions.”
Optiva OTS-1LNG modules feature a robust API (application-programmable interface) design, 30dB Tx and Rx adjustable gain range, SmartGain for enhanced AGC (automatic gain control) performance, peak optimizer for quick and easy setup, and RF power monitoring via the front panel and SNMP. They feature DWDM operation that increases transport capacity without increasing fiber count and, when housed in the same Optiva chassis with other Optiva cards, enable a full-redundancy system in a single chassis.
