GigOptix has begun sampling the new Surface Mounted Technology (SMT) GX62255 Mach-Zehnder Modulator (MZM) driver that is ideal for 100G optical transponders. The GX62255 MZM driver combines two 32 GB/s 8Vpp channel drivers into one compact form factor system.
The dual channel system substantially decreases both the Electromagnetic Interference inside the system and the region required, to execute the driver section. Every 100G transponder utilizes two GX62255 units to augment the data signals from the multiplexer of the transmitter, to drive the MZM. The new MZM driver is designed for convenient interfacing with the 100G DP-QPSK MZMs, and it offers optimal signal coupling.
The MZM driver dissipates less than 1.8 W of power for every channel, at 7.5 Vpp. It also features an adaptable output amplitude and a flexible eye cross point. The driver delivers minimal RMS jitter degradation.
GigOptix’s VP of Marketing, Padraig O’Mathuna stated that the GX62255 MZM driver addresses the requirements of transponder developers who look to decrease the power dissipation, cost, EMI, and size inside the transponder designs, while offering a relocation path to SMT for the existing customers of GPPO connectorized GX62455.
