1.3 Block Diagram
Each E-O converter is fully integrated and contains the laser source, lithium niobate (LiNbO
3
) Mach-Zehnder intensity modulator
(MZM), and automatic bias controller; the only required external input is the signal source to the Modulator RF In port.
The MX40G/MX70G, MX40G-LB/MX70G-LB, and MX40G-1310/MX70G-1310 include a C-band tunable laser, an L-band
tunable laser, and a 1310 nm fixed-wavelength laser, respectively. Both the C- and L-band laser sources are tunable on the ITU
50 GHz grid and include a dither feature for wavelength stabilization. An external laser source, operating from 1250 nm to
1610 nm, can also be used to provide the optical input.
Either the internal laser or an external laser source may be coupled to the Laser In port, which uses PM fiber with light linearly
polarized along the slow axis, as shown on the front panel. The maximum input power to the Laser In port is 20 dBm (100 mW).
Optical power is monitored in three places (Mon-1,-2,-3) for the purpose of enabling bias and power control. These power values
are also available at the I/O port. Mon-1 is at the Laser Input, Mon-2 is at the MZM Output, and Mon-3 is at the final Optical
Output.
