ModBox 1550 nm 44 Gb/s NRZC, L bands ; 100 Mb/s - 44 Gb/s Reference Transmitter

SDelivering Modulation Solutions
ModBoxThe ModBox-1550nm-44Gbps-NRZ is an optical modulation unit that generates
high performance NRZ optical data streams. The equipment incorporates amodulation stage based on a high data rate LiNb03 Mach-Zehnder modulator,
coupled with a high performance 44 Gb/s RF driver and an automatic bias
control circuitry. It can also receive an internal laser source (DFB, ITLA...) anda photodetection stage.
The ModBox-1550nm-40Gbps-NRZ provides R&D and production engineers
with state of the art performance and the peace of mind of a turn-key instrument.
It can be used as a reference transmitter in optical telecommunications
laboratories, or in production test beds.
In addition to the traditional 1550 nm wavelength range, it is also available
at 1310 nm, 1060 nm and 850 nm.

Absolute Maximum Ratings

Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are absolute stress ratings only. Functional
operation of the device is not implied at these or any other conditions in excess of those given in the operational sections of the data sheet. Exposure
to absolute maximum ratings for extended periods can adversely affect device reliability.
