As Hospitals and clinics become reliant on their network to include mobile devices and new apps, clinics and hospitals are being forced to examine the health of their network infrastructure to provide improved security and maintain reliable bandwidth accessibility.

Old legacy infrastructures were not designed to handle the influx of security issues and mobile devices used by healthcare constituents – physicians, nurses, administrative staff, lab technicians, patients, and their families. Nor were they designed to handle high volumes of traffic or accommodate internal hospital services while providing connectivity to today’s mobile apps. Today’s mobility infrastructures can grant network access to anyone placing a drain on resources. The real challenge is ensuring that the hospitals and clinics networks have the proper security while providing a mobility infrastructure is always on, enforces the highest level of security and patient privacy, and provides self-service workflows for guests and staff.

That’s what Tevetron’s Covalent Connect delivers.

Tevetron provides optical backbone network that delivers – a secure, industry-compliant intranet network and mobility infrastructure that’s always on and ultra-dependable. Tevetron’s Covalent Connect infrastructure for healthcare networks provides secure network topography and accommodates any number of users, devices, and apps to ensure the best possible secure network and mobility experience. This is especially critical as the industry is exposed to constant security attacks and tougher competitive model of managed care where providers focus on the quality of patient care and preventive health maintenance to increase revenue and reduce costs.

Tevetron’s Covalent Connect fiber optic backbone network infrastructure and mobility solutions are designed for hospitals and clinics to satisfy a wide range of critical healthcare applications and security issues. Tevetron’s network is provides:

Tevetron’s optical backbone network is based on a “bubble” which incorporates a highly secure segmented hierarchical design for departments, group devices within the networks. The Tevetron network designs are organized in a secured “bubble” segments which are divided into groups based on non-Internet delivery connectivity design.

The “bubble” segmented hierarchical design model has two basic layers:

• Optical Distribution Layer: Interconnects and segments “bubbles” for internal networks
• Optical Access Layer: Provides connectivity end devices for each department

Tevetron’s Covalent Connect “bubble” segmented network provides advantages of dividing a network into smaller, more manageable department blocks that is independent of Internet connectivity traffic with clearly defined boundaries between modules. This provides clear demarcation points so that the network designer knows exactly where the traffic originates and where it flows.

Tevetron’s Covalent Connect Optical Access Layer, within the bubble, provides the link to the end-user and manages the separation of undesirable or no relevant traffic. As more devices and applications are added to Tevetron’s covalent connect “bubble” network, response times are unaffected because each additional device application will be designated to its own connectivity pathway. It eases the design task by making each module independent. The network can focus on the needs of each department separately and provide scalability by allowing the hospitals and clinics to add modules seamlessly and to add services and solutions without changing the underlying network infrastructure.


Fiber Optic Backbone Network Benefits

Our Covalent Connect Fiber Technology has the ability to carry more data than copper networks, for instance, Cat 6 cable has a maximum installed length of 295 feet - no matter what the application is. Taking advantage of fiber backbone cabling solution, our technology can support gigabit Ethernet up to 40,000 meters. Ultimately, when fiber optic cable is installed as a backbone cabling solution - the level of flexibility attained is much greater. The Covalent Connect has capability of delivering Mbps to Gbps data rates within the network providing increased bandwidth and expandability where needed.

Historically, few healthcare organizations have deployed robust networks to provide secured network services, simply because they have not been necessary. Now, the whole public health system is being digitally tied together, putting a greater strain on network applications and security needs than ever before. Hospitals will have a tremendous need for robust networks that support the increase in data volume and security requirements of EMR systems. Hospital and clinic administrators need to understand the healthcare application and security network needs in addition to the technology.

With the implementation of EMR regulations, some hospitals and clinics will go out of business due to the fact that they cannot afford to meet compliance. This will result in major hospital mergers which will have huge impacts on network services as they try to manage security and patient tracking systems, while doing it with zero downtime. Access to critical EMR and CPOE systems will be required from all corners of the hospital, as well as to affiliate organizations over the WAN. Traffic volume on hospital networks will continue to rise to new heights, with network services scrambling to ensure the network infrastructure can keep pace.


Key Considerations

If the healthcare network does not properly support EMR and CPOE, the hospitals and clinics might not survive the next several years. In many hospitals, implementing the EMR system in-house requires an overhaul on the network infrastructure, security applications, data warehousing, and application servers. Rather than take on this massive expense, some hospitals are considering the use of hybrid or private cloud services to host the EMR system. Regardless of how the service is hosted, digitizing patient data and making it secure and accessible for healthcare providers is a daunting.

Hospitals and clinic administrators have to ask themselves, how will they are data be merged during a hospital acquisition? What affiliate organizations outside the hospital will need access to patient data? How will their network share this data while staying in compliance with security regulations? Is the infrastructure ready for a huge spike in traffic load? If a hospital or clinic is suffering performance problems, this will impact the ability for physicians to provide efficient patient care, which can cause patients to go elsewhere and result is a loss of revenue for the hospital.

On the wireless side, hospitals have long been front-runners in supporting tablet and other wireless devices. However, as these are used by physicians and nurses to drive EMR, CPOE systems and for basic patient care, the increased data volume and security requirements will strain the wireless infrastructure, pushing it to its limits in throughput and coverage. This will especially be the case when large medical images such as MRI scans and X-Rays are accessed from the bedside. With the influx of patient devices such as iPads and smart phones, the network structure will need to have the capability of providing proper security, network functionality, staff access, and guest access while maintaining bandwidth for critical hospital equipment.


Fiber-Optic Backbone for Communications and Network Control

Tevetron’s covalent connect optical backbone networks can be utilized in three major categories: office connectivity (department communication), facility and network system communication, and staff-guest connectivity. Office connectivity is what we are most familiar with; it includes such services as e-mail, time entry, billing, and other office utilities you would typically access from an office desk. The and network systems provide data services for equipment software applications and equipment monitoring connectivity and building equipment such as air-handling equipment, lighting control, power monitoring, UPS monitoring, and battery monitoring. Staff-guest connectivity provides communication internally (intranet) and externally (phone and Internet) use.

Typical networks have in common is that they are using Ethernet as the communication protocol and can be supported by the enterprise information technology (IT) network. The typical cabling infrastructure provided by IT can handle network protocols other than Ethernet, but the standard network equipment and architecture typically would not, our network has this capability. Tevetron’s Covalent Connect Network incorporates fiber strands in the fiber backbone for connectivity; this gives Tevetron’s network the capability of implementing data rates of Mbps to Gbps through the IT Ethernet network equipment. Tevetron’s network architecture provides bandwidth allocation and network segregation between the different departments and “bubble” networks within the topography. Tevetron’s network has capability of handling a multiplex the data in various formats such as using virtual LANs (VLANs) to isolate the network traffic.

The fiber backbone security topography provides the segregated security networks for departments and applications, while eliminating the need for separate network switches, rooms, and backbone fiber cable, to systems where security is just another device on the enterprise network with their own VLAN.


Managed Optical-Ethernet Delivery for Multi-Service Hospital WAN Network

The Covalent Units provide multiple delivery capabilities with our unique point to point, multi point to point, and multi point to multi point link architecture for WAN applications and services.
The Covalent Multi-Service Platform consists of X-Gigabyte switches, Covalent Service Provider Unit, and the Covalent-N Units.

The Covalent Multi-Fiber Network can be applied to a Campus WAN or a Utility WAN that is deploying Ethernet, Wireless, Coax and T1 connectivity.
The Ethernet data is delivered throughout the wide network, and segregated by department with the Covalent Service Provider Unit.

The Covalent Service Provider Unit delivers multiple forms of data through the employment of multiple data channels (our WDM wavelength configuration) over a single or dual fiber strand that runs the length of the Networks fiber-optic topography. Circuits from a Service Provider are connected to the Covalent Service Management Unit, and the Ethernet switch provides connectivity to end users of different departments of the Ethernet network.

Optical WAN image

The Covalent Service Management Unit provides deliverability of multiple data channels on separate frequencies onto the fiber cable (the common fiber line) connecting the corresponding end user Covalent-N unit. Covalent-N units are used to drop off one channel(s) of Ethernet to the end user switch. The Covalent-N contains our Add+Drop Multiplexer (typically defined as a OADM) which selects the corresponding wavelengths of the network traversing the common fiber line while allowing the non-related packet data to be delivered to the corresponding Covalent-N Unit and network switch.

The Covalent-N has the ability to operate as direct line deliverability (single fiber connected to each unit creating the connection topography) or can be designed to deliver bi-directional Channel ports simultaneously; this enables the corresponding optical traffic to be managed at each building using the general port configuration of the Covalent-N. The delivery architecture enables us to assign Ethernet channels to specific frequencies which are delivered and managed at each building. This multi-frequency channel capability provides the covalent-N unit of managing multiple frequency selection for each channel port configuration in the network.

The Covalent Service Management Unit enables management of the entire network of Covalent Systems equipment using the management software application. The Covalent-N (1U high) units consist of a fiber transport module and multi-port connections (2 to 16 channels are typically used in this fiber transport module).

The Covalent network systems incorporate a unique intelligent design that requires very limited management software while supporting advanced features, including VLAN, Quality of Service, multiple channel configurations and bandwidth control.

This Wide Area Network application the Covalent Multi-Service platform enables new services over an existing network infrastructure without installing new fiber or upgrading legacy network equipment. The Covalent management system reduces operating costs and improves network reliability with remote configuration, greater security, and performance monitoring and fault management tools.
