CyOptics launches 10G TOSA enabling 80km TDM and DWDM capability in SFP+ transceivers

Indium phosphide-based optical chip and component maker CyOptics Inc of Lehigh Valley, PA, USA has launched a series of 10Gbps transmit optical subassemblies (TOSAs) that address the emerging dense wavelength division multiplexing (DWDM) SFP+ transceiver market, expanding its portfolio of transmitter and receiver components for optical transceivers. The new TOSAs offer a minimum 30% reduction in power consumption versus the current-generation TOSAs.

The 1655 (40km) and 1656 (80km) series TOSAs are compatible with the 10Gbps miniature device (XMD) multi-source agreement (MSA) and integrate a high-speed electro-absorptive modulated laser (EML), a monitor photodiode and a micro thermo-electric cooler (TEC) in a small-form-factor metalized ceramic package. The TOSAs operate at data rates of up to 11.3Gbps and are available in the full range of C-band ITU-T wavelengths.

“Network equipment manufacturers are rapidly deploying SFP+ transceivers because they provide a smaller footprint and are more cost effective than XFP transceivers,” says Daryl Inniss, VP & practice leader at market research firm Ovum. “The new CyOptics TOSAs enable module manufacturers to offer a complete portfolio of SFP+ transceivers. We project 10Gbps DWDM pluggable transceivers to grow at a compounded annual growth rate of over 30% from 2010 through 2013, representing one of the fastest-growing market segments in the optical component space,” he adds.

“The new CyOptics TOSAs augment the application space of the SFP+ form factor to now address all types of 10Gbps applications with the inclusion of metropolitan-area 80km TDM and DWDM links,” says CyOptics’ CEO & president Ed Coringrato, who claims that the firm is first to ship such TOSA technology, which enables higher system port density and lower power consumption.

The 1655 and 1656 TOSAs exhibit the same wavelength stability as their 162x predecessors, supporting operation at 100GHz channel spacing over 20 years, with low hazard rates (~100 FIT). At a package case temperature of –5ºC to +75ºC the 165X series consumes a maximum of 0.45W (40km, DWDM) and 0.5W (80km, DWDM), suiting SFP+ (Class II) applications. Alternatively, for industrial-temperature applications with a case temperature of –40ºC to +90ºC the TOSAs consume only 0.85W (40km, DWDM) and 0.95W (80km, DWDM), a reduction of about 35% from its predecessors.
