Overview
Finisar’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). 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).
The transmitter wavelength can be tuned up to any of the 43 different Dense Wavelength
Division Multiplexing (DWDM) wavelengths across the entire C-band in 500 ms. This
increases operational efficiencies in deploying DWDM networks and reduces inventory of
transmitters at different fixed wavelengths. Wavelength tunability also opens the possibility
of novel HFC architectures that can dynamically route services and increase bandwidth
capacity in the cable operator’s access network.
Key Advantages
2x to 4x density improvement over current transmitter solutions
At least 50% less power consumption per transmitter
Enables future HFC architectures to route services dynamically by changing the
wavelength of the transmitter
Enables pluggable optics to be utilized directly in next-generation Cable Modem
Termination Systems and QAM modulators
