MHz square-wave) input signal. The ANSI
T1E1.2 committee has designated the
possibility of defining an eye pattern mask
for the transmitter output optical power as
an item for further study. Avago will
incorporate this requirement into the
specifications for these products if it is
defined. The HFBR-1116TZ transmitter
typically complies with the template
requirements of CCITT (now ITU-T) G.957
