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
