Optical power considerations

When you connect the device to collocated equipment, ensure that enough optical attenuation exists

to avoid overloading the receivers of each device. You must consider the minimum attenuation

requirement based on the specifications of third-party equipment. For more information about

minimum insertion losses for Avaya optical products, see Installing Transceivers and Optical

components on the Avaya Virtual Services Platform 4000 Series, NN46251-301.

Dispersion considerations for long reach

Precise engineering of transmission links is difficult; specifications and performance are often

unknown, undocumented, or impractical to measure before equipment installation. Moreover, the

skills required to perform rigorous link budget analysis are extensive. Fortunately, a simple,

straightforward approach can assure robust link performance for most optical fiber systems in which

you use Avaya switches and routers.

This method uses an optical power budget, the difference between transmitter power and receiver

sensitivity, to determine whether the installed link can operate with low bit error ratio for extended

periods. The power budget must accommodate the sum of link loss (that is, attenuation), dispersion,

and system margin, described in the following paragraphs.

Link losses are the sum of cabled fiber loss, splices, and connectors, often with an allocation for

additional connectors. Cabled fiber loss is wavelength and installation dependent, and is typically in

the range of 0.20 to 0.5 dB/km. See the cable plant owner or operator for specifications of the cable
