What is Power and Why Does it Matter in Optical Circuits?

Amps, Watts and VoltsOptical Power, DB and DBMOTDR, Link Budgets and Link LossesWe all know transceivers require electrical power to operate. Commonly this specification is expressed in terms of Watts. Formally, it is expressed as: Watts = Volts x Amps, or W = V x A. Why is this important? If we know how many watts are required, we can determine how much power is required at each transceiver port in the switch to ensure the tr...See more on approvednetworks RP Photonics
