=0 V.
1. Noise frequency is 1 kHz to 10 MHz. Voltage is peak-to-peak value.
2. Noise frequency is > 10 MHz. Voltage is peak-to-peak value.
3. Measured between 0.8 V and 2.0 V.
4. Measured for all optical data channels with reference to the optical
FRAME channel.
A link operating distance of 75m at maximum data rate is supported
when using a low skew fiber ribbon cable (skew specification < 1.2
ps/m, fiber bandwidth > 160 MHz
·
km). Longer link distances are
supported at lower data rates.
