20G Analog LD
Series:
ORI-MZM-T-BW is the thermal tuning version, whose phase shift is tuned by micron heaters integrated on chip. Compared to traditional LN modulators, the heater version could maintain a lot more stable bias point throughout lifetime of the device. The device is a hermetic sealing package with internal optical power, which save more space size for the end user.
