SYSTEM DESIGN PARAMETERS
6.1.1. Electrical to Optical Parameters
In optical output devices, the main design parameters that are important are the launched output power,
the wavelength and the linewidth. Launch power and wavelength are always important in system designs.
Line width is usually important only in high definition applications.
6.1.1.1. Transmitter Output Launch Power
The launched output power tells us the maximum power available at the optical transmitter. Table 6-1
indicates the launched output power available on current Evertz EO modules.

6.1.1.2. Wavelength
The wavelength of the optical signal determines the cable loss window within which the system will
operate.
The Loss versus Wavelength graph in Figure 6-2 shows that at 1310nm the cable loss is 0.40dB/km and
at 1550nm the loss is 0.30dB/km.
