| 43Gb/s, C+L-Band, LN, Lightwave Modulator Rackmount |
|
 |
The Optilab LMD-43 is a high performance digital lightwave transmitter designed for broad bandwidth
applications up to 43 Gb/s. This rackmount unit includes an internal Lithium Niobate (LN) optical intensity
modulator, and an ultra-broadband RF driver with matched impedance, as well as a built-in Automatic Bias
Control (ABC) board which allows a stable operation over long operating periods of time. The external laser
source can be any polarization maintaining device, such as a fiber laser, tunable laser, or fixed wavelength
Distributed Feedback (DFB) laser, making it a versatille solution.
Features
• 40 GHz Modulator
