Broadband Fiber Explained

The OpenCape network is the only 100% end-to-end fiber optic network covering southeastern Massachusetts and Cape Cod.

The OpenCape fiber optic network is designed for high reliability with redundant equipment and fiber paths to withstand the region’s harsh marine climate.

OpenCape wants you to know the facts about our fiber optics compared to all other Internet access choices.

Units of Measurement - Megabits and Megabytes

Broadband speed is typically measured in megabits per second, commonly stated as Mb or Mbps (i.e. 15Mb or 15 Mbps).  However, speed requirements are rapidly increasing, with gigabit speeds (Gbps) quickly becoming the new standard for economic development and institutional use.

The OpenCape network is architected for high speed access with multiple segments of the network from 10 Mbps to 100 Gbps.

Bandwidth vs. Speed

There are two different factors to consider when measuring speed.

  1. Bandwidth refers to the size of the conduit in which the data is traveling within.
  2. Speed refers to the rate at which the data is traveling at. Bandwidth simply refers to the size of the "pipe" in which it is travelling.

Using that definition, you can quickly see that a larger bandwidth will permit more data to travel, which will also increase the rate at which it travels.

However, this does not necessarily mean that the speed of your broadband connection will be the same as your bandwidth.

For example, let's say you're transferring a file at 128kbps. If you start to transfer another file it will compete for bandwidth and slow your speed down. If you increase your bandwidth by adding another 128kpbs ISDN line, your first file will still travel at 128kpbs, but now you can transfer both files at 128kbps without sacrificing speed.

An analogy would be a highway with a 65mph speed limit. Even if more lanes were added to handle more vehicles, the speed limit is still 65mph.
