Data Centers

Data Centers Need the Most Bandwidth

The data center is often an early adopter of technology because it consumes the most bandwidth and is the focal point between an Enterprise and its data. As business needs continue to grow, Enterprises often find themselves increasingly needing to synchronously and securely mirror critical data across data centers in real time.

As the need for data exchange continues to evolve, data centers become consolidated in metro areas, resulting in greater network-management complexity, especially as capacity expands to meet demand. XKL optical equipment is designed with scalability in mind, and will not add to the management burden as a system grows.

In a data center where space and power is at a premium, XKL products fit in nicely at 100 Watts per Terrabyte (or 0.1W per 1Gb) and 1U rack space, allowing these facilities to wisely utilize the space and power available to them. With XKL’s DQT400 product, data centers can leverage the soft configurable interface and future scaleability/upgradability features from 100G to 400G. This will enable data centers to grow their operation and maintain a future proof product that addresses technology evolution. Scalability and growth up to a 48-channel, 400G system is now easily accomplished using XKL’s DQT400 product line along with DMD filter.

Reducing Complexity of the Network

Mega data centers are beginning to arise in metro areas, and the need to manage them in a minimal way to reduce costs continues to be a dominating factor in running the business. The physical layer and infrastructure must perform at the highest levels and maintain continual uptime. IT staff will have varying levels of experience, and not every staff member will be an expert. Designing Layer 1 equipment that interfaces much the same way as a router makes it much easier to manage. Using familiar router commands ensures the junior staff can troubleshoot and keep the system up and running.


The global Data Center Interconnect (DCI) market continues its annual exponential growth. Large portions of DCI spending come from communications service providers, and the demand for high-capacity low-cost optical gear is on the rise. As data centers consolidate and cluster in metro areas, there is a big need for more DCI to reduce energy consumption, carbon footprint, and cost.

The biggest operating cost for a Data Center is power. XKL’s energy-efficient products can help reduce this expense, while facilitating a more cost-effective approach to future bandwidth allocation.

Data Center Interconnect

XKL - data center interconnect

Whether you are bringing large data projects in-house, providing low-latency service to your development division, or provisioning a colocation center to mirror and back up your cloud server clusters, you will need a backbone to move that data around. Each pair of XKL systems creates a low-cost, low-latency, minimum of 100Gbps private backbone for your critical infrastructure. Deploying XKL systems for the DWDM optical network reduces OpEx and CapEx for your large data plans. Link your key applications to the data and bandwidth your users need, with the low latency they expect. Your organization already has the IT skills, and we will help you get connected.

A Solution for Increasing Your Operational Capacity

Basic data center infrastructure requires power, cooling and cabling. Future-thinking data centers consider a high-capacity, lowest-possible-latency optical backbone as an integral part of that infrastructure. Furthermore, building a robust DWDM foundation in a data center provides another tier of pricing options. Install and set up an XKL optical networking system in under an hour, right out of the box. No optical experience is needed to implement an XKL system, which comes with a familiar router-like user interface. IT administrators will feel right at home.

Go optical from floor-to-floor in your own building and realize the simplicity of connecting switches, routers, servers or computers. Management and monitoring of the entire XKL network is a snap: it’s done through an integrated optical service channel or the front panel copper ports.

Data centers have to make sure that bandwidth and connectivity for their big clients is in place and available even before their users know they need it. You can build a simple private optical backbone using XKL systems that aggregate multiple 10G Ethernet links and Fibre Channel ports into 100Gbps of mixed traffic through each 1U XKL system. Designed and priced for enterprise environments, XKL systems are managed and monitored just like the routers and switches already installed. Time to install out-of-the box is less than an hour, and no optical experience is necessary.

Cloud Migration

As more and more mission-critical apps and data move to the cloud, the impact of an outage becomes an increasing concern. It is more important than ever for companies to avoid any type of outage, as its cost cannot be underestimated.

Many cloud outages are due to a lack of manageability. When faced with upgrading firmware or updating software in their server, router, switch or transport nodes, network owners have to bring down part (or all) of the network to achieve these improvements. At best, this destabilizes service for users; at worst, it completely disrupts service. You don’t want to take the network out of service entirely for “preventive maintenance.”

With XKL DWDM equipment, upgrades don’t require a hard reboot or specialized optical engineering staff. Overall management is straightforward and easy, and can be done without affecting customer traffic. Not only does this keep network users happy, it can keep your company off the “biggest cloud outages” lists!

Network Design

Network design is more than simply deciding on a topology. Designers need to understand how fiber-optic systems work, their capabilities, codes and regulations, as well as customer needs for data transmission, distance, scalability, and logistics. One of the most important aspects of a solid design is the optical power budget. This is the ratio of minimum output signal power to the minimum acceptable receiving power to ensure a clean signal. This is closely related to the loss budget, which is the estimated loss in signal strength due to factors such as splices, attenuation, distance to be traveled, connections, dependability of the power supply, and environmental factors.

The power budget must be robust enough to accommodate the loss budget, with enough signal strength to produce dependable data  transmission. If one of these budget estimates is inaccurate, it can be very costly, both in terms of money and network strength.

At XKL, we have a comprehensive understanding of how fiber-optic networking happens, and what it takes to build a robust fiber-optic networking system. Let us help you design the network that best meets your needs.

Software Defined Networks

Traffic in a software defined network (SDN) is centrally managed using software. With a comprehensive view of the entire network, software manages traffic flow and network routing, while relying on the flexibility of the network design. SDN provides a data center with the flexibility to tailor data management to the needs of its customers: cloud computing, large data analysis, media streaming, high-speed trading, or any other networking requirement.

While SDNs can greatly improve the performance and flexibility of a network, they can’t prevent data loss. The most well-managed network is useless if data transmission is not reliable. XKL systems are robust, dependable, easy-to-install, and require minimal monitoring. As your customers’ needs increase, it’s easy to add capacity without sacrificing space or greatly increasing your operating costs.
