Insertion loss, or the loss of signal that happens along the length of a fiber optic link, is expressed in dBs and should always be a positive number. But it can be negative (which isn’t a good thing).

Return loss, which measures the amount of light reflected back toward the source, is also expressed in dBs and is always a positive number. A high return loss is a good thing and usually results in low insertion loss.

Reflectance, which also measures reflection and is expressed in dB, is a negative number. High reflectance is not a good thing.

아름다움은 피상적인 것이 아니다

While neatly combed bundles of cables might look really nice in exposed overhead cable trays and in racks and cabinets, this aesthetically pleasing deployment isn’t always a thing of beauty when it comes to performance.

Sometimes this can be hard to explain to your customers who seem to care more about how the cable looks versus how well their data transmits.

Going the Distance

A couple of weeks ago, we published a Cabling Chronicles Blog about exceptions to the 100-meter (m) channel length rule and the fact that you can’t necessarily go the full distance due to temperature rise, gauge size and subsequent insertion loss and DC resistance.  But did you know that you can also EXCEED the 100 m length? Let’s take a look at that scenario.

An Exception to Every Rule

An Exception to Every Rule

You’re watching a baseball game, the batter hits a fair infield fly ball, and the umpire calls the batter out even though the ball isn’t caught.

You might be thinking, “Hey, that’s not the rule.” But in fact, if the umpire judges that the ball “can” be caught by an infielder with runners on first and second base (or bases loaded) and there’s less than two outs, it’s considered an “infield fly” and the batter is out to prevent a double or triple play.
