What is black fiber?

Dark fiber can seem daunting to the imagination. Maybe these strands are related to another fantastic and malicious domain with intent. Nevertheless, black fiber is scary only from the point of view of an unused resource. Black fiber refers to an unused fiber optic cable.

What is black fiber?
What has fiberEver asked the cable or telephone company to dig up your parking lot or the beautiful landscape of your business to improve or correct connectivity? It's a problem for you and the company. Thus, instead of hiring teams to dig large tracts of land over and over again, companies often set more lines than expected to meet the potential capacity of the network. Most fiber assets available today reflect the optimism of the telecommunications boom of the late 1990s.

Unused fiber left on the market by a subsequent telecom bus has been labeled black fiber. Not because these strands of optical fiber are particularly harmful, but rather because they are not used; no data is sent in the form of light pulses on the cable lines.

Black fiber cable strands can be rented to individuals or businesses to make connections. It only makes sense that the cable company was looking to secure the future, but wants to make money in the meantime.

How to access the dark fiber?
Technology now allows access to unused spare capacity and packaging. The individual customer can rent unused fiber optic strands to create a private network. The customer can then adjust the wavelength and speed of the network traffic to fit the service platform of his choice. Users can overlay any necessary protocol while maintaining the flexibility to extend and control their network connectivity needs.

The purchase of the dark fiber allows the customer to control the cable itself, but is also responsible for remote monitoring, maintenance and repair.

Benefits of black fiber
Businesses that need high-bandwidth fiber optic connectivity can reap the many benefits of renting dark fiber:

Dark networks have a higher capacity (several data signals can even be transmitted simultaneously at different wavelengths)
Separate from the main network, the dark fiber is controlled by the client
A proprietary network is highly secure and the configuration can be customized
Who uses black fiber?
The underlying infrastructure for the dark fiber optic cable is essentially the same as the fiber on. Yet, instead of building a new connectivity network or partnering with a network operator, those on the dark fiber path are finding lower infrastructure costs and better control. For those who do not have the resources to manage a network by themselves, many opaque fiber optic providers offer wavelength-managed services that include support and expertise.

A communication service provider may extend its service or offer more accessibility in a particular area by grafting itself onto a black fiber network.

In a separate use case, financial institutions that manage technological innovations might want to implement a variety of interfaces over a carrier's standard options. By choosing to use dark fiber, the company gains the ability to customize network connections and better control the hardware used.

Municipalities with low latency applications could also find cost savings in dark fiber as they take direct control of transmissions and related equipment.

Edison Carrier Solutions, a Southern California Edison business unit, has more than 5,000 miles of fiber optic network in a 50,000 square mile service area. For more than 20 years, the company has been providing critical connectivity for standard single-mode fiber in point-to-point or ring configurations as rental options.
