How You Can Benefit From Wavelength Services

By: John Shepler

What do you do when you have a need for high bandwidth, security and flexibility in your WAN connections? This may be the time to take a closer look at wavelength services.


What tradeoffs should you do to ensure that you’re getting the right bandwidth for your operation? Certainly, there is the protocol competition between the dedicated point to point line services provided by SONET/SDH and Ethernet over Fiber. Both will get your packets from point A to point B, but you may find that locations lit for EoF have access to much higher bandwidths for the same lease price or a cost savings if you don’t need a BW upgrade.

One important consideration is the protocol that you wish to transport. Ethernet is easiest to connect and most efficient over Ethernet WAN services. SONET/SDH is designed for TDM, but can also support packet switched networks. The waters have been muddied lately by the addition of Ethernet over SONET that gives you Ethernet services running on mature SONET fiber optic networks.

Another tradeoff worth doing is lit fiber vs dark fiber. Wavelengths are a lit fiber service. They are fully managed in the sense that the carrier provides the fiber path plus the terminal equipment that accepts and delivers your traffic. You don’t need to be concerned about the inner workings of the network because the carrier takes care of that for you.

The big advantages of dark fiber are improved security, since you are providing the terminal equipment at each end of the fiber, and the ability to create your own wavelengths. You’ll need to invest in the CWDM (Coarse Wavelength Division Multiplexing) or DWDM (Dense Wavelength Division Multiplexing) equipment. By doing that, you can have as many wavelengths as you wish, each running a different protocol. You can even multiplex wavelengths to create higher bandwidth pipes.

Private Networking With Wavelength Services

There comes a time in the growth of a company when standard telecom services just won’t get it done anymore. This is when the IT department starts contemplating buying or renting dark fiber to get the bandwidth, latency and control they need. There’s another alternative that should be considered, however. That’s managed wavelength services.

What’s a wavelength? It’s one color or lambda on a fiber optic strand. That’s right, fiber optic lines have more than one light beam running through them. Each color represents a different wavelength or frequency of laser light. Because they are different colors, these light beams will mix within the optical fiber strand but one will not interfere with another. It’s like they are completely different pairs of wires in a copper bundle or channels on a cable system.

Why have multiple wavelengths? It’s a matter of efficiency. The cost of the equipment to transmit and receive multiple lambdas is far less than the cost to trench or fly hundreds or thousands of miles of fiber optic cable. Each cable has multiple strands. Each strand has multiple wavelengths. Because of this, each fiber installation has massive bandwidth capability available for commercial use.

The technology that makes wavelengths possible is called DWDM or Dense Wavelength Division Multiplexing. The “dense” designation means that many wavelengths are loaded onto the fiber with close spacing between them. DWDM terminal equipment must have precise and stable control of the grid of light wavelengths on the fiber. There is an ITU (International Telecommunications Union) standard for this so that equipment is common for the industry. There can be as many as 160 channels or wavelengths, all in the infrared C and L bands, on each fiber strand.

What carriers who own fiber assets are doing is offering entire wavelengths for lease to companies that need high levels of bandwidth. Integra Telecom is a good example of a company offering wavelength services on their metropolitan and long haul fiber optic network. One of the nice features of wavelengths is that you can pick your protocol. Integra offers traditional SONET Interface options of 2.5 Gbps and 10 Gbps. You can also get Ethernet Interface options of 1 GigE and 10 GigE.

What Integra is offering is called managed wavelength services. That differs from dark fiber, where you are responsible for all the terminal equipment on each end of the fiber, or unmanaged wavelengths where the carrier simply feeds a wavelength with the signals and perhaps interface modules that you supply. A managed solution means that Integra is responsible for providing the terminal equipment and monitoring the network 24/7 with surveillance and network alarms from their Network Operations Center (NOC).

What you get is a highly reliable, high bandwidth, low latency point to point optical wavelength service for long haul or metropolitan connections. Integra operates a 5,000 mile high speed long haul network with metro services in many major cities of the Western United States and connections to Chicago, New York City, Ashburn, VA, and Dallas. Within the 35 markets across 11 Western states, they operate a 3,000 mile metro access network that includes more than 1900 fiber-fed buildings. If your business is located in Arizona, California, Colorado, Idaho, Minnesota, Montana, Nevada, North Dakota, Oregon, Utah or Washington, you can benefit from the Integra best-in-class fiber optic network, including wavelength services.

What types of businesses are ideal for wavelength services? Companies needing business continuity and disaster recovery solutions, Ethernet transport and optical storage connectivity or data storage connectivity. If you have more than one data center, chances are you need the “big pipes” that wavelengths can provide.

100 Mbps Corporate Ethernet

A new standard connection speed for medium to larger organizations is getting to be 100 Mbps. It may sound like an expensive and unnecessarily large network capacity, but it is actually neither. Fast Ethernet is the new DS3.

For those who remember only a few years ago when a T1 line offering 1.5 Mbps was considered a high bandwidth connection, the notion that 100 Mbps is now the benchmark may be a bit unnerving. A lot has changed over the last decade. Application requirements have increased dramatically. We might have settled for fuzzy slow motion video conferencing when even that was a novelty. Now it’s full motion HD two-way video and telepresence. E-commerce has gone from an add-on service for a bricks and mortar facility to the dominant way that many companies do business. Dynamic interactive web pages with video have replaced low resolution static HTML brochure pages.

There are also many businesses that can’t operate electronically without high bandwidth connections. These include video production, content delivery and medical imaging. It’s 100 Mbps, 1 Gbps, 10 Gbps... or forget it.

There’s no reason to forget it anymore. High bandwidth services are readily available and lower in cost than you may imagine. That’s the other big change between the start of this decade and the end. Line prices have plummeted as new competitive carriers with the latest network technology have come on the scene. While T-Carrier and SONET may be the entrenched legacy carrier services, Ethernet has become the bandwidth solution of choice. On a Mbps and Gbps basis, Metro Ethernet and Carrier Ethernet solutions are often a fraction of the price demanded for T-Carrier or SONET and a small fraction of standard pricing ten years ago.

Fast Ethernet at 100 Mbps makes a lot of sense as a bandwidth requirement for dedicated Internet access or point to point and multipoint connectivity. The standard Ethernet LAN speeds are 10 Mbps, 100 Mbps and 1 Gbps. In some cases, that’s been increased to 10 Gbps. Many, Many networks have most of their nodes running at 100 Mbps simply because so much equipment has network interface cards standardized at 10/100 Mbps. The big speed bump has been at the edge of the LAN where it connects to the outside world. Fast Ethernet may be more than adequate for internal file transfers. But going from 100 Mbps inside to a 1.5 Mbps T1 line outside can slow traffic to a crawl.

Medium and larger companies have reduced the speed bump by upgrading from T1 to DS3 connections. DS3 offers 45 Mbps, a bandwidth increase of 28x when line overhead is factored in. The new replacement for DS3 is Fast Ethernet at 100 Mbps. That’s more than double the bandwidth, a protocol that is directly compatible with corporate LANs, and a cost savings to boot. What’s not to like?

Is your company missing out because you thought that 100 Mbps was beyond your reach? Take a few minutes right now to get 100 Mbps Fast Ethernet prices and availability. You may well be able to get more bandwidth for less than you spend now.

Ethernet Offers Lower Cost Carrier Grade Fiber Solutions

High bandwidth users, such as major corporations, large medical centers, independent phone companies, video production houses, and Internet service providers, have a new option to get the carrier grade bandwidth they need at prices much lower than they’ve been used to paying. The game changer is Carrier Ethernet.

Carrier Ethernet describes a metropolitan and long haul bandwidth service based on Ethernet rather than traditional telco TDM technologies. Within a single metropolitan area, the service is often called Metro Ethernet. These services are professional grade bandwidth solutions that offer high reliability as well as high dedicated bandwidths.

Ethernet can be carried over long distances on existing SONET/SDH fiber optic networks, or the newer MPLS networks that are favored by competitive service providers. Last mile connectivity can be over fiber, twisted pair copper or wireless.

Ethernet over copper? Yes, in fact it is called just that. EoC uses multiple copper pair telco cables and new generation terminal equipment to transport Ethernet via copper cabling that is already provisioned to most business locations. How much bandwidth can you expect from such a solution? Standard 10 Mbps Ethernet and fractional bandwidths such as 1, 2, or 5 Mbps are typical selections. High level bandwidth up to DS3 replacement levels of 45 Mbps are sometimes available depending on distance to carrier facilities.

For Fast Ethernet at 100 Mbps and above, fiber optic transport is essential. Larger businesses and organizations now consider 100 Mbps a reasonable bandwidth level to support their highly computerized operations. The good news is that Ethernet pricing is not only competitive with TDM based services such as DS3 and OC3, but actually much cheaper on a Mbps basis. You may be shocked to hear that you can get 100 Mbps Fast Ethernet service at prices you’d expect to pay for DS3 at 45 Mbps. If you have a long-standing bandwidth contract, you’ll likely find Ethernet service a downright bargain.

Even Gigabit Ethernet at 1000 Mbps is within reach of many larger organizations and those whose businesses are bandwidth-intensive. If you need more than that, 10 GigE at 10,000 mbps is available in major metropolitan areas. Even 100 Gbps is coming soon. Why? Because the productivity improvements possible with high speed connectivity justify the cost.

That cost is getting easier and easier to justify. Carrier Ethernet services are expanding rapidly into medium as well as large metro areas. The ease of interfacing and managing an Ethernet WAN service make it the connectivity of choice regardless of price. But with prices lower, not higher, than traditional bandwidth solutions, it’s pretty hard not to insist on Carrier Ethernet.
