A new process technology which improves the modulation efficiency of the LN modulator
chip, and a wideband G3PO RF interface instead of the GPPO RF interfaces used in conventional 100G DP-QPSK modulators
keep the package compact while achieving doubled transmission capacity over standard LN modulators
The transmitter component of an optical transceiver comprises a light source and an optical modulator
that encodes data into the light emitted by the light source.
The first Telcordia qualified volume production of 40Gb/s and 100Gb/s DPSK modulators
will be available in the fourth quarter of 2010.
One of the more significant characteristics of the modulators
is a low output noise floor, particularly for RFID applications.
As with many MEMS-based devices, however, the challenge for both MEMS modulators
is to reduce the required drive voltage.
Three years ago, when GigOptix acquired Lumera, we could only dream of what the proprietary polymer material could accomplish and with the full Telcordia qualification of the TFPS modulators
, we finally see one of those dreams turn to reality," stated Dr.
experience some degradation in performance due to the various process variations and imperfections in the circuit elements.
The LX8220 is a small form factor, low power consumption modulator
designed for use in 40G metro, long-haul and ultra long haul optical transport applications.
One good example of Multi-Mix technology is a three-channel vector modulator
assembly with a reference channel designed and manufactured for a military Global Positioning System application involving search-and-rescue operations.
OTCBB: GGOX), a leading supplier of high performance electronic and electro-optic components that enable next generation 40G and 100G optical networks, announced that its LX8401 40G Mach-Zehnder modulator
implemented using GigOptix's proprietary Thin Film Polymer on Silicon (TFPS[TM]) technology has successfully achieved two major milestones in its product commercialization.
The obvious advantages of the Blue Cell II family of I/Q modulators
are low cost and small size.
The I and Q modulators
take the DC control signals from the I and Q channels and the RF input signals and create output signals, which are modified in phase and amplitude.
