The X5 and Z5 are 10Gbps intensity modulators,single GPO RF port;4.5dB low insertion loss,extinction ratio greater than 30dB,extinction ratio can exceed 40dB or 50dB,low drive voltage.The biggest difference is that the latter has fixed chirp.
Description The X5 and Z5 single drive 10 Gb/s modulators with integrated photodiode are ideally suited for use in long reach (LR)/ very long reach (VR) Metro applications as well as in long haul (LH) transmission. The X5 is a fixed zero-chirp solution, compact packaged. The X5 modulator operates over the C and L band. Its low drive voltages make them compatible with low power dissipating driver solutions such as GaAs driver technology. In addition to providing bias control feedback, the new enhanced photodiode is capable of power monitoring for control of the transmitter’s modulated output power. Features
