MODULATOR DRIVER
WJ’s10Gbpsmodulatordrivers
AnRFevolutionforOC-192
The SA1137 is another addition in WJ’s series of
hybrid-based products optimized for OC-192 networks.The SA1137 is a full-function amplifier
capable of driving LiNbO
3
modulators. The
SA1137’s limiting action can actually improve on
multiplexer rise and fall times. This makes the
SA1137 an excellent choice for optical RZ and
NRZ systems alike. The SA1137 is designed for
the full range of OC-192 data rates from 9.9Gbps
through 12.25Gbps (FEC rate).
