Power-efficient 10G TOSA for DWDM SFP+ transceivers

CyOptics Inc., maker of Indium Phosphide (InP) optical chip and component technologies, announced a new series of 10 Gbps transmit optical subassemblies (TOSAs) for the emerging DWDM SFP+ transceiver market.

The TOSAs offer a reduction in power consumption of at least 30% versus current-generation TOSAs, says a representative.

The 1655 (40 km) and 1656 (80 km) series TOSAs are compatible with the 10-Gbps miniature device (XMD) multi-source agreement. The new optical components 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 11.3 Gbps 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 Ovum’s vice president and practice leader Daryl Inniss. “The new CyOptics TOSAs enable module manufacturers to offer a complete portfolio of SFP+ transceivers. We project 10-Gbps 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.”

"The new CyOptics TOSAs augment the application space of the SFP+ form factor to now address all types of 10-Gbps applications with the inclusion of metropolitan area 80-km TDM and DWDM links,” says Ed Coringrato, chief executive officer and president of CyOptics.

The 1655 and 1656 TOSAs exhibit the same wavelength stability as their 162x predecessors, supporting operation at 100-GHz channel spacing over 20 years, with low hazard rates (~100 FIT).

At a package case temperature of -5 to +75C the 165X series consumes a maximum of 0.45 W (40 km, DWDM) and 0.5 W (80 km, DWDM). For industrial temperature applications with a case temperature of -40 to +90C, the TOSAs consume only 0.85 W (40 km, DWDM) and 0.95 W (80 km, DWDM), an approximate 35% reduction from its predecessors, according to a representative.
