Passive component testers are a combination of firmware and hardware that, as noted earlier, must be correctly configured for your specific product. Many PCTs offer the following features:
Insertion Loss/Return Loss module, which contains light sources and a...
Do you have difficulty achieving straight preforms? This is definitely an art and requires some practice. I have found procedures that deliver a reproducible technique. For example, setting the optimum H2/O2 ratio can prevent preform sagging and glass burn-off during...
Step 2. Ensure you have the proper equipment.
The precision of polishing equipment dimensions (both the fixturing as well as the machine itself) play a vital role in determining your process capabilities. Properly maintained polishing machines should last for...
Fundamentally, Insertion Loss is the loss of power that results from inserting a cable into a network or transmission path. Keep in mind that, inevitably, some power is lost because every connection represents a break in the fiber optic system. That’s why your...
In regards to MT ferrule geometry measurements, Minus Coplanarity (or Minus-Side Coplanarity) is one way to describe how “flat” or “co-planar” an array of fibers is to ensure minimum optical performance requirements of the telecom world, it is important to...
This mainly applies to fixtures for polishing ferrule only (as opposed to connector polishing). The ferrules must protrude the same amount from the bottom of the fiber optic polishing fixture, to ensure consistent pressure being applied to all...
From Fiber Optic Connector Cross Sectioning and Analysis observations from “Connector A” notes.
Observations: This particular connector had multiple fractures inside ceramic ferrule (photo A.1-A.3) and a substantial length of fiber missing. See photos...
Laser cleaving shows also a significant process advantage for large-core fiber applications with SMA connectors terminated as the laser beam cuts thicker fibers which are more difficult to scribe.

Epoxy De-gassing:
When a two-part epoxy is mixed, it is very likely now filled with many small air bubbles. These bubbles MUST be removed prior to injection into a ferrule (production lines commonly use centrifuges or vacuum chambers to remove gasses /...
