The two wavelengths used for Insertion Loss testing
QUESTION:  What are the two wavelengths used for Insertion Loss testing?     ANSWER:   In standard Singlemode cable assembly, the two wavelengths used for Insertion Loss testing are 1310nm and 1550nm.  All Singlemode fibers work very similarly in either...

IL @ 1550 higher than 1310
IL @ 1550 higher than 1310 A connector, or an entire product design, showing a significantly higher Insertion Loss at 1550 than at 1310 indicates the likely presence of a stress point on the fiber somewhere in the cable assembly—most likely a fiber bend that...
Diameter of the ferrule’s hole bore is larger than the outside diameter of the fiber
The ferrule hole bore must be slightly larger in diameter than the fiber to allow the fiber to be inserted into the hole. The smaller the ferrule hole diameter, the more precisely the fiber will be centered in the ferrule (thus, lower Insertion Loss can be expected)....
Connectors aligned and contacted optimally
The ideal (minimum-loss) fiber path would have NO connections. Instead, it would be one continuous, straight-through glass fiber from Point A to Point B – with no interruptions. Since fiber networks usually require connectors for modularity, path splits, etc., we...
Domaille 3200 Inspection Microscope
Watch now … The Domaille OptiSpec® DE3200-S2 Bare Fiber+ allows inspection of bare fiber end face and with a quick turn the bare fiber side profile. The additional position for a standard connector makes the DE3200-S2 ideal for production departments and engineering labs.

Assess the quality and condition of test cables
When it comes to assessing the quality and condition of test cables, first ensure the test cable’s connectors are clean. Next, take a close look to ensure they are in good condition. Keep in mind that both connectors and coupling sleeves don’t last forever. They...

AFL’s Test & Inspection Division Relocates to Westford
Westford, MA and Spartanburg, SC – June 12, 2019 – AFL, an international manufacturer of fiber optic cable, accessories and equipment, announces that its Test and Inspection Division expanded and relocated from the Lowell, MA office to Westford, MA, allowing AFL...
IL @ 1310 higher than 1550
IL @ 1310 higher than 1550 A connector, or an entire product design, showing a significantly higher Insertion Loss at 1310 than at 1550 indicates a likely problem in core-to-core alignment between the two mated ferrules.   The difference may be small, and indeed...
