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 exceeds...

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 need...

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 may...

IL @ 1310 and 1550 similar

IL @ 1310 and 1550 similar If made properly, the cable assembly will test about the same at either 1310 or 1550.  1550 Insertion Loss results are generally better by a few hundredths of a dB, due to, in part, its lower fiber attenuation.    It’s normal that Insertion...

IL/RL explained

Most likely, your testing specifications present minimum requirements for a Low IL and High RL. If your production facility is challenged with meeting the desired IL/RL specs, there are common causes you can investigate and address. However, before addressing common...

Passive component testers and wavelength

For the most part, corporate and government communication entities connecting data centers around the world – bringing fiber to the office (FTTO) and fiber to the home (FTTH) – have standardized measurement wavelengths. When researching passive component testers,...
