possible. If the value of the cap is too high, it will
slow down the fast signals edges, and, if its value is
too small, it won’t be able to hold a constant change
between the first bit and the last bit of a long string
of identical bits in a low data rate application. This
leads to higher pattern-dependent jitter in the
transmitter signal. 0.1µF is found to be good for all
applications from 155Mbps to 2.7Gbps.
AC-coupling the laser to the driver brings a solution
to the driver headroom problem at the expense of
extra components, loss of part of the modulation
current wasted in the pull-up network, and additional
power consumption.
