Simulating Multi-Fiber and MPO Cable Links

Posted by Kevin Miller on Tue, Jun 15, 2021 @ 12:06 PM

In today’s advanced fiber optic networks, multi-fiber cabling is utilized both inside data centers and across vast field networks as it provides the most efficient approach for deploying large counts of fibers using as little physical space as possible.  At the most basic level, a multi-fiber cable is typically comprised of a ribbon cable surrounded by a protective outer jacketing.  These ribbon and/or multi-fiber cables are available with number options when it comes to fiber counts (ex: 8, 12, 24, etc)

What is Wavelength Division Multiplexing (WDM)?

WDM is a technology approach that allows for the combining ("mux") of multiple individual light wavelengths (signals/channels) from multiple lasers on a single fiber using a passive component for transmission to another location. At that receiving location, WDM components then work in the reverse, demultiplexing ("demux") the combined wavelengths back into individual signals and routed to their respective receivers.

Driving Value with Radio Frequency Over Fiber (RFoF)

Wireless technology and fiber optic communications have revolutionized everyday life.  In her article, Radio Meets Fiber Optics: RF Over Fiber, Marie Christiano states that “using radio frequency (RF) signals, wireless has given us military radar, avionics, cellular and satellite communications; our world is safer and more interesting thanks to all the benefits provided by wireless breakthroughs. We no longer need to be ‘homebased’ for an expected call or to catch a podcast; our banking, fitness routines, transportation, communications and home security can all be scheduled and controlled from our mobiles.”
