My last two web exclusive articles (part 1 and part 2) have covered how optical time domain reflectometers (OTDR) work and make measurements. Now let''s get into
Aug 01, 2025
The condition and characteristics of fiber optic connectors greatly affects the performance of an installed fiber optic link. High connector loss (e.g., insertion loss), low return loss, or high
Nov 28, 2025
Optical fiber is a fantastic medium for propagating light signals, and it rarely needs amplification in contrast to copper cables. High-quality single mode fiber will
Nov 19, 2025
Gainers in fiber certification ultimately don''t gain you anything but headaches and increased cost. Accurate optical loss measurement can be done by testing in both directions from one end.

Measuring Reflectance or Return Loss Reflectance Reflectance (which has also been called "back reflection" or optical return loss) of a connection is the amount
Apr 30, 2026
For a single-mode connection, an offset of 0.3 microns will produce a loss of about 0.4 dB. An important aspect of this offset loss across a pair of connectors is that it''s not a simple scalar

The Basics: SC vs. LC Fibre Optic Connectors Both SC and LC fibre connectors do more than just terminate the cable – they''re part of bringing your business
Jun 16, 2026
All connectors are very sensitive to forces acting on the cable as it exits the backshell. Just handling fibers to make measurements can cause readings to
Feb 26, 2026
Fiber optic connectors are an essential component of any fiber optic network, allowing for the connection and transmission of optical signals between devices.
Jan 31, 2026
Key performance characteristics for selecting a connector are discussed, including the insertion loss (attenuation), return loss (reflection loss), and the number of possible mating cycles.
Feb 07, 2026
Insertion loss for a connector or splice is the difference in power that you see when you insert the device into the system. For example, take a length of fiber and measure the optical power
Jan 10, 2026
What is optical fiber loss? Fiber loss can be also called fiber optic attenuation or attenuation loss, which measures the amount of light loss between
