Fiber capacity keeps up with demand

Submitted by acohill on Thu, 07/19/2012 - 12:47

While the cellular wireless networks are groaning under the massive growth in bandwidth use by their mobile customers, fiber capacity just keeps growing and growing. The optical transmission manufacturer Huawei has announced that they have been able to transmit 2 Terabits (2 Tbps) on a single WDM (Wave Division Multiplexing) channel. A single fiber can have many individual channels. A terabit is one thousand gigabits, so Huawei is shoving two thousand gigabits down a single wavelength of light, and they are saying they can boost the capacity of a single fiber to 56 terabits.

It's like I've been saying for a long time...fiber future-proofs your community. If you still think wireless is a viable alternative to fiber, ask yourself why cellular rates keep increasing while the cost per megabit for fiber keeps decreasing. It's all about physics, supply and demand, and fiber has plenty of supply because the PHYSICS ARE DIFFERENT.
