Gigabit to 10 Gigabit to 100 Gigabit WAN
Author: John SheplerDemand for enterprise WAN (wide area network) bandwidth has accelerated as more operations migrate to the cloud and more employees work remotely. Fortunately, there are many good vendor solutions for creating high-bandwidth point-to-point and Internet connections.
Fiber Optic Ethernet WANFiber optic connectivity is now the gold standard for business bandwidth. If you're using basic T1 lines, ISDN PRI or DS3 bandwidth, you're probably running out of bandwidth and getting old. Many carriers have begun phasing out buyer-based services due to high maintenance costs and declining customer interest. It's time for an update.
However, not all fibers are created equal. The legacy of SONET technology, introduced decades ago by telephone companies, is also aging. Even better, the new standard is called Carrier Ethernet or Ethernet WAN.
Fiber optic Ethernet WAN is an extension of standard switched Ethernet used in almost all local area networks. Technical standards make it easier to connect LANs to WANs without intermediate protocol changes. It is Ethernet through and through. This is the standard offered by most service providers, including older telephone companies that have adopted it for their networks.
The advantages of fiber Ethernet WANs include the ease of scaling bandwidth without the need to replace interface hardware. Order a 10-50 Mbps starter service and easily upgrade to 100 Mbps or 1 Gbps, usually using an online portal or a phone call. Unless you need a service, truck movements are rarely needed beyond what the terminal equipment can handle.
The price is very attractive. You can start with low-bandwidth services ranging from 10 Mbps to 100 Mbps and likely pay less than copper-based services. You almost always get more bandwidth for the same price or pay less for additional bandwidth at the same level of service.
As bandwidth increases, cost savings become more important. As the speed increases, the cost per Mbps or Gbps decreases compared to traditional solutions. As technology improves, carriers build fiber routes and competition increases, and so do costs. If you have a contract for more than a few years, you can probably save money with a new service.
Multi-gigabit solution
There was a time and many years ago that 1 Gbps or 1000 Mbps broadband or private line service was the holy grail of connectivity. Fiber is not as rare as it used to be. Fiber broadband is now common in metropolitan business areas. There are many competing suppliers which often result in very attractive prices.
Fiber deployments are increasing as more commercial bandwidth and cell towers are upgraded to support millimeter wave 5G cellular service.
1 gigabit bandwidth is common for enterprises, and more demanding applications move to 10 gigabit service. The next step is a 100 Gbps fiber optic Ethernet WAN. While this may seem excessive for small businesses, it is not unreasonable for large hospital campuses and medical centers with multiple imaging facilities. Other major users include universities, research laboratories, government agencies, video production houses, architectural firms and manufacturers. The bandwidth that 5G wireless supports in excess of 1 Gbps is quite enough for highly automated businesses that have implemented a 10 Gbps digital transition that cable companies offer at least as much to consumers. 100 Gbps is the next logical increase.
Dark fiber and fixed wireless access
The fiber-enabled WAN may remain the business standard for the foreseeable future. However, there are specific situations where related technical solutions make sense.
Dark fiber is an option for businesses that want more control over their connections as if they owned the link. Additional fiber optic cables are available from many network vendors for spare parts and future expansion. They may be willing to lease an entire fiber line or a wavelength of cable. The available ones depend on where you want to connect. The advantages of dark fiber include the ability to run any protocol and the added security of having only one user on a given fiber or wavelength.
Fixed Wireless Access (FWA) uses microwave frequencies to carry traffic instead of fiber. Many cell phone companies use FWA to route traffic to remote towers instead of long, isolated fiber routes. Bandwidth can range from gigabit to 10 gigabit and offers dedicated personal line service or Internet connection. Think of FWA as a fiber without the physical fiber. Instead you have an antenna on the building. A major advantage of FWA is that fiber trenches can be installed in months rather than days, which is currently unavailable.
Ready to upgrade your bandwidth from old copper service or expensive SONET fiber? Fiber optic Ethernet WAN, dark fiber and fixed wireless access can deliver what you need at a better price than ever.
