What is polarity? And why is it important?

Polarity defines direction of flow, such as the direction of a magnetic field or an electrical current. In fiber optics, it defines the direction that light signals travels through an optical fiber. To properly send data via light signals, a fiber optic link’s...

How does WDM technology differ from parallel optics?

Whereas Wavelength Division Multiplexing (WDM) utilizes a single fiber, parallel optics uses multiple fibers and lanes at various transmission rates. At the 25G transmission rate and at 100 meters, for example, IEEE’s 400 Gb/s migration path requires 16 lanes (16 MMFs...

Will WDM/SWDM ultimately replace parallel fiber optic solutions?

The consensus among FOTC members is that both solutions will coexist and depend upon specific data center network goals and applications. Employing parallel fiber solutions are currently necessary to transition between speeds, so that breakout capability is...
