Pluggable transceivers are one of the most useful and accessible parts in fiber optics.

You simply have to plug them into the switch, or the switches, of your choice. However, the one specification that users should always think about when utilizing transceivers is the optical input power.

The common mistake

A common mistake that happens when using optical transceivers is that users tend to accidentally burn them out by overpowering the input side of the module. In other words, the module gets damaged from the overabundance of incoming light signals.

This tends to occur more often when customers are using longer reach parts that can go 40km, or even 80km. Longer reach parts have more sensitive receivers than shorter reach parts, so they overload more easily, causing premature end of life.

How to prevent burnout

Users can avoid this issue simply by looking at the data sheet of the optic, making sure to stay within the overload and damage thresholds. Actively monitor this by using a Digital Optical Monitoring (DOM) screen, which shows the transmit and the receive powers.

So, as long as the receive power is within thresholds, users do not have to deal with these sorts of issues.
