The laser is housed in an SFP+ form factor transceiver module.

March 9, 2006 Anaheim, CA -- At OFC/NFOEC 2006, Redfern Integrated Optics (RIO), a provider of optical transmitters for telecom, datacom, and other applications, is offering a live demonstration of its directly-modulated 10-Gbit/sec external cavity laser (ECL) transmitter optical sub-assembly (TOSA) for 40- and 80-km DWDM. The laser is housed in an SFP+ form factor transceiver module.

The SFP+ transceiver module consists of the company's 10-Gbit/sec 1550-nm ECL TOSA and an AGC PIN/TIA receiver with linear output, which the company says allows for host-based equalization for fiber impairments, as well as for longer PCB trace. The company says the compactness and low power consumption of the TOSA enables the small form factor transceiver to operate over distances up to 80 km in both TDM and DWDM applications.

The device's cavity design is based on the company's PLANEX technology, consisting of a planar waveguide with an integrated Bragg reflector and a high-speed gain chip. The company says the device provides a narrow spectrum with negative chirp, for extended transmission reach, high output power, and wavelength stability sufficient for 50-GHz DWDM application, without requiring use of a wavelength locker.

The device and demonstration can be seen at the company's booth #2373 at OFC.

"RIO maintains a strong commitment to providing superior, cost-effective, high-performance, and reliable solutions to meet the small size, low power consumption, high optical power, and low cost requirements of the optical communications industry," comments Radu Barsan, president and CEO of RIO.

RIO has also announced a collaboration with Broadcom to jointly promote the upcoming SFP+ MSA for 10-Gigabit applications. "XFI technology and the XFP module represent a quantum leap in the evolution of 10-Gbit/sec transceivers," remarks Ali Ghiasi, senior principal scientist for Broadcom. "We're encouraged with RIO's ability to effectively enable SFP+ to perform at 10 Gbit/sec for extended reach applications."
