Layout Guidelines
For optimum performance, use 50Ω transmission lines (100Ω differential) for connecting the signal source to the
DIN+ and DIN– pins and 50Ω transmission lines (100Ω differential) for connecting the modulation current
outputs, MOD+ and MOD–, to the laser. The length of the transmission lines should be kept as short as possible
to reduce loss and pattern-dependent jitter.
