Optical CRZ transmitter using mach-zehnder modulator |
摘要 |
An optical CRZ transmitter using a Mach-Zehnder (MZ) modulator is provided which enables a simple construction process and has reduced production cost. The optical CRZ transmitter includes a logic operation unit for performing a logic operation between a received NRZ (Non Return-to-Zero) data signal and clock signal data signal and a clock signal, , and generating electric RZ (Retum-to-Zero) data; an amplifier to amplify the electric RZ data; and a MZ modulation unit to modulate the amplified electric RZ data into an optical signal, and impose a chirp signal on the optical signal by varying an input voltage of the amplified electric RZ data. <IMAGE>
