F-tone Networks¡¯s XFP-RF transmitter is a small form factor hot-pluggable optical module that is compliant with interface specifications developed by the Society of Cable Telecommunications Engineers (SCTE). The wavelength of the transmitter can be electronically set to any of 43 DWDM wavelengths across the entire C-band in less than 0.5 second. An integrated wavelength locker keeps the wavelength within 2 GHz of the wavelength center over the life of the transmitter. It can be fully loaded with digital QAM channels from 50 MHz to 1218 MHz to enable cable operators to more effectively segment their serving groups and offer more services to their subscribers. The small XFP module significantly reduces power consumption and increases density for downstream transmitters. These modules can be integrated into today¡¯s Hybrid-Fiber Coaxial (HFC) optical broadband platforms and tomorrow¡¯s converged
access platforms (CCAP).
