March 8, 2006 Fremont, CA -- This week at the OFC/NFOEC show in Anaheim, California, the Optical Internetworking Forum (OIF) is demonstrating the interoperability of transponders and optical components for Very Long Reach (VR) applications using alternative modulation techniques.
OIF members Azna, Essex, Kodeos Communications, Opnext, and Vitesse are conducting the live demonstration at OIF's booth #1149, in conjunction with test equipment suppliers Agilent, Anritsu, JDSU, and Tektronix.
The participants are demonstrating the interoperability of an application code for VR links. The OIF, working in conjunction with the ITU-T, SG 15 developed the code (P1V1-2C2) as part of the ITU-T G.959.1 specification. The code was accepted by the ITU during its February 2006 meeting in Geneva.
According to the OIF, the application code is based on alternate modulation techniques supporting transmission through 2400 ps/nm of residual dispersion without regeneration or in-line optical compensation. The code supports carrier requirements for longer reaches at lower costs and allows for direct upgrade of 2.5 Gbit/sec to 10 Gbit/sec VR links.
"The test methodology was derived from the OIF's transponder interoperability implementation agreement to ensure multi-vendor compatibility," explains Sandia National Laboratories' Karl Gass, the OIF's Physical Layer Users Working Group chair. "This is an opportunity for component and module suppliers to demonstrate the maturity of a new industry standard."
