QPSK-OM-40 – 1550 NM 40 GHz IQ Modulator
The Optilab QPSK-OM-40 is a 40 GHz IQ modulator. It consists of a dual parallel Mach-Zehnder (MZ) interferometer modulators embedded in a main MZ super- structure, also known as a nested MZI modulator. This IQ modulator features high bandwidth up to 40 GHz and low drive voltage to support 2Vpi drive requirement. The use of X-cut Lithium niobate and symmetrical design ensure very low chirp and skew between I and Q channels.
