DESCRIPTION
The Electro-Absorption Modulator module consists of electro-absorption modulator with built-in cooler. The modulation signal is applied to the modulator while the CW laser propagating through electro-absorber allowing low wavelength chirping. The module includes an thermistor and a thermo-electric cooler to stabilize the performances. It is polarization maintaining fiber coupled.
FEATURES
Low Chirp, High Extinction Ratio
Low Operating Voltage at 40 Gbps
High Bandwidth and Built-in TEC
APPLICATIONS
High-speed Optical Fiber Communication
Microwave Photonics
