Ciena as an Original Equipment Manufacturer (OEM)

Ciena is an original equipment manufacturer (OEM), and many of the products offered by the brand are mentioned below in detail. Its inventory centers on the packet networking and optical network transmissions realms.

Partnerships With Other Companies

As other brands recognized Ciena’s dedication to networking advancements, some made OEM agreements with Ciena to expand their capabilities. For example, in August 2006, Ciena entered into an OEM agreement with ANDA Networks, Inc. to market, sell and support the company’s products.

Then, in December 2007, Ciena agreed to supply the BT Group with Ethernet equipment for 21CN, a British Telecom project to update its network and save an estimated £1 billion in year on year operating costs — the equivalent of approximately $1.3 million based on present-day currency conversion calculations.

The anticipated cost savings were partially due to plans to integrate 16 separate-service networks into a single infrastructure with support for multiple networks. Numerous Ciena technologies streamline existing or new systems, making the company a smart choice to meet the BT Group’s needs.

Ciena Ethernet Services

 Ciena Carrier Ethernet

Even people who are not very tech-savvy are familiar with Ethernet. This common networking technology is directly responsible for how people access and transmit data since it runs local-area networks (LANs). Ciena manufactures an assortment of Ethernet-related equipment available from Worldwide Supply.

Ciena specializes in Carrier Ethernet (CE). It’s ideal for operators offering networking services to their end users. CE came about in the early 2000s when companies began looking for ways to extend the Ethernet protocol for wide-area network (WAN) connectivity.

Both standard Ethernet and CE offer scalability to enterprise users, but many clients prefer CE because it implements converged networks that bring residential, business and wireless traffic together to reduce costs.

Ciena also provides scalable bandwidth for Ethernet connections. It lets customers make dynamic adjustments to meet capacity requirements within a specialized interface offered as part of the Operations, Administration and Maintenance (OAM) tools that come with relevant Ciena products.

Additionally, the OAM features provide real-time monitoring of Ethernet VPN connections, including connectivity checks. Metrics about periodic latency let service providers immediately spot notable trends and take action as needed.

More than 75 percent of business-service bandwidth usage comes from packet networking. Whether you’re interested in CE or the traditional kind of Ethernet, Ciena’s equipment handles both depending on the type you buy. The scalability aspect of Ciena’s products suits your business growth goals, too.

Ciena Optical Transport

 Ciena Optical Network

During our interactions with clients who want to buy and sell used Ciena networking equipment, we encounter people interested in optical transport solutions. Instead of relying on electronic signals to send information, equipment for optical-based communication networks uses light signals to transfer data between at least two points.

Some variations exist between optical transport networks, but there are similarities, too. For example, all optical networks include fiber-optic cables, which send signals from node to node. There are also switches that ensure those signals end up where they should.

Optical signals consist of pulsing lasers that repeatedly turn on and off. The speed of the optical signal depends on how fast the beams activate or deactivate, plus how far each pulse spreads out during a transmission. The length of travel for a pulse is called dispersion, and as dispersion goes up, it becomes more difficult to differentiate between adjacent pulses.

Several factors influence dispersion, such as the length of the fiber-optic cable and the type of cable. Combining several types of fiber for even faster transmissions is possible, too.

Optical networks play primary roles in accomplishing faster, more reliable network speeds. Analysts believe Ciena is on course to enjoy long-term success due to the desire of multiple network providers to upgrade their potential speeds to at least 100G.

Verizon is one of the companies working with Ciena for their optical networking services. That partnership is notable because Cisco was the only other OEM included in the contractual agreement. Ciena began its initial deployment of optical network services to Verizon in 2016 as part of a multi-year plan.

The company realizes that entities attempting to get a head start on making the transition to 5G technologies must adopt all-encompassing approaches to meet that goal. In February 2018, Ciena announced a suite of products aimed at assisting enterprise customers with their 5G upgrades.

Ciena has the knowledge and technological resources to guide customers through the various stages equipping their existing systems to work with 5G, whether through upgrades or replaced equipment.

Brand growth for Ciena could feasibly come as a result of its Waveserver, a stackable data center interconnect (DCI) platform that’s especially popular with enterprise customers.

The Waveserver permits real-time analysis of network parameters, thereby enabling network operators to make intelligent conclusions about how to maximize bandwidth. It can provide 200 Gb/s wavelengths across several hundred miles and more.

Furthermore, Ciena offers its Liquid Spectrum technology, combining programmable hardware with advanced software applications. It enables monitoring all-optical network assets and utilizing them for best results in real time. Then, network providers allocate capacity for networks that need it most.

Ciena Video Services

Ciena Cloud Services

Ciena caters to media and entertainment (M&E) companies that wish to keep pace with customers’ ever-growing desire for streaming video content available on demand, whether it’s live sports coverage or television episodes.

People in today’s society expect to click a video clip and start watching the content within a second or less. If companies cannot meet that expectation, customers understandably get frustrated and may look for other service providers to satisfy their hunger for reliable video content that starts playing almost immediately.

Many M&E companies use Ethernet and optical networking options for their content creation and production needs. Both technologies provide the scalability necessary to handle the changing characteristics associated with video quality levels and customer demands.

Ethernet and optical networks are also compatible with most commercial equipment used by video-creation experts. They allow sending material between numerous entities, as well. That advantage enhances collaborative efforts between multiple parties by equipping them to distribute video content on dedicated, stable networks.

Besides wanting video content without delay, today’s consumers expect current material. The video-specific products Ciena offers support that desire, too. People commonly go online after hearing about a breaking news story. Consumer trust rises when news sources provide them with streaming videos showing news reports shortly after events occur.

For example, Ciena has technologies that allow news crews working on location to use optical or Ethernet networks to immediately send footage to the cloud, making it accessible to a production team responsible for taking care of additional preparations necessary before an upcoming newscast. Also, video specialists in remote locations can retrieve content from the cloud and review it almost instantly, then provide feedback to other members of a team.

People who view video content don’t necessarily do it on televisions. Anyone who owns a Wi-Fi-connected device such as a tablet or smartphone is potentially a consumer of online videos.

And people willingly pay for video content if the quality of it meets their minimum expectations. Statistics from a Ciena-sponsored survey revealed that 72 percent of respondents thought about the quality of videos viewed when picking new providers of paid video content.

Companies that do not address video quality from the beginning and continuously seek to improve it risk falling behind in an ever-competitive marketplace. Ciena has the tools needed for high-quality, stable videos delivered in today’s fast-paced world to media-hungry viewers.

The brand’s 6500 packet-optical platform combines optical transport, plus IP and Ethernet packet networking, thereby delivering extraordinarily quick speeds for transmissions to and from data centers. In addition to offering configuration to support numerous services, the 6500 supports future reconfiguration if a company’s needs change.

Multi-layer encryption keeps all data center interconnections secure. The encryption extends to stored content and transmissions in progress. A high level of security provides peace of mind, especially when M&E companies transfer exclusive content or sensitive information.

Ciena WDM Transport

Wavelength division multiplexing (WDM) is a method of maximizing investments by enhancing the capabilities of existing fiber-optic networks. It increases bandwidth by permitting various data streams to travel simultaneously over one virtual fiber-optic network. Therefore, it is a leading technology for transporting large amounts of data between destinations.

Like traditional fiber-optic networks, WDM uses light for transmissions. It involves various channels of light, each with a distinctive wavelength. The uniqueness of the wavelengths ensures the channels do not interfere with each other.

An effective WDM setup requires wavelength-specific lasers called transceivers that convert data signals from SAN and IP switches to optical signals, preparing them for transmission into the fiber-optic cable.

It’s also necessary to invest in a piece of equipment called a multiplexer. The multiplexer optimizes the use of the fiber optic network by collecting all the data streams to get transported at once. The data streams later get separated into different channels again at the other end of the fiber-optic cable.

There are two types of WDM. Coarse WDM (CWDM) has less than eight active wavelengths per fiber. Companies use CWDM for short-range communications. A CWDM system has wide-range frequencies with each one spread far apart.

Lasers go through temperature changes during operation and make wavelengths drift. CWDM relies on standardized channel spacing that accommodates for those fluctuations. CWDM is a cost-effective solution if you are interested in WDM and not concerned with spectral efficiency.

Whereas wavelengths define CWDM systems, the second type of WDM — dense WDM (DWDM) — has a frequency-based definition. A DWDM system works best for long-distance transmissions, especially if paired with erbium doped-fiber amplifiers (EDFAs) that increase the performance capabilities and allow for communications spanning thousands of miles.

DWDM features from between a few dozen to over 100 wavelengths crammed onto the confines of a fiber-optic cable. Unlike CWDM systems, DWDM wavelengths do not have generous amounts of space between them. Over 40 channels can fit into the frequency range used for only two CWDM channels.

High-precision filters enable targeting one wavelength without interfering with those nearby. Plus, all DWDM systems have extremely precise lasers that work at a constant temperature. The tight packing of the wavelengths in DWDM does not allow for the variations that happen due to temperature changes associated with CWDM.

Ciena is a pioneer of DWDM technology, and that distinction resulted in deployments across the United States when the company partnered with well-known communication brands including MCI WorldCom and Sprint in the 1990s. That success motivated Ciena’s initial public offering in February 1997. The IPO resulted in a first-day market capitalization of $3.4 billion, the most substantial to-date achievement of that kind for any startup company benefiting from venture capital.

Ciena offers its 6500 Packet-Optical Platform for people interested in WDM transport. It handles packet data, optical transport networks and WaveLogic Photonics — which relate to a proprietary Ciena technology — at once to simplify operations while maximizing a company’s reach and capabilities.

Furthermore, the 6500 has hybrid Optical Transfer Network and packet-switching technologies that promote the best use of available resources. Ciena also offers built-in software tools to increase control and visibility of optical networks.

Customizable solutions maximize operational efficiencies in other ways, too. The adaptability component of the 6500 is yet another factor that can keep costs down due to the way it adjusts to various client-specific requirements.
