Systèmes d’imagerie médicale nécessitant un réseau avec beaucoup de bande passante

Provins Hospital Center, France

AROONA serves digitization of patient information

The customer’s issue

The Hospital Center of Provins is in the process of digitizing patient information for all of their services. This requires large digital files to be accessible at all times across the entire campus. In particular, the OM1 fiber link between the core server and the psychiatric service, located 326 meters
[1070 ft] away in a remote building, does not support sufficient bandwidth and requires an upgrade. However, the Hospital Center cannot allow hospital services to be interrupted nor disturbed by construction work.


The AROONA solution

Cailabs’ passive solution AROONA-SMUX enables a retrofit of the hospital’s existing fiber link, satisfying its need for minimal disruption: all vital services remained online and the absence of construction work avoided hindrance. This favorably differentiates AROONA-SMUX from a new fiber deployment.


The benefits of the solution

  • 4 x 10 Gb/s throughput instead of being limited at 100 Mb/s
  • 3x less expensive than a new cabling deployment
  • 3 hours of installation, no service interruption, no dust generated by installation

New digital services to support improved medical care

Digitization and data centralization pose a major challenge to the development of the Hospital Center Léon Binet in Provins, located near Paris, France. The hospital is in the process of implementing the Electronic Patient Record, which involves centralizing each patient’s data and making it accessible across the entire campus at all times.

This process coincides with two other axes of improvement being implemented at the hospital, each one also generating a large amount of digital data: deployment of new, specialized digital services for each department, and increased connectivity of the biomedical equipment, including sophisticated MRI scanning facilities that generate very large data files of very high-resolution images.

The facilities of the Hospital Center of Provins are scattered across remote buildings, with old generation OM1
(62.5/125 µm) fiber links in between. That being said, the hospital’s IT department is faced with the challenge of the fiber infrastructure having an intrinsically limited capacity, which cannot support the ever-increasing need of higher bandwidth to manage new services.




“We have many bandwidth consuming services at the hospital, such as medical imaging services. AROONA-SMUX provides a very good alternative to installing new optical fibers in situations where one is limited to 100 Mb/s by the existing multimode fiber. The quick installation of AROONA-SMUX allows for a significant gain in both time and money.
I would recommend this solution to other IT colleagues who are dealing with the same issue of needing to increase the bandwidth in their LAN.”

Complexity of a new fiber deployment in a hospital

The most limiting fiber link on the campus connects the main building, where the imaging facilities and storage equipment are located, to the psychiatric service located 326 meters [1070 ft] away in a remote building. This OM1 fiber link can only support 100 Mb/s, which is not sufficient for instant access to the centralized digital patient record.

The conventional solution is to deploy a new single-mode optical fiber. However, the hospital environment involves specific constraints which are incompatible with a new deployment. The deployment of new fibers for this 326 meter long link would definitely cause significant disruptions.

Given the large distance between the buildings, laying out a new fiber would require at least a few days. This is not an option for the hospital, which cannot close and must have all its vital services available online at all times.



Upgraded optical multimode fiber link: 326 meters [1070 ft]


Moreover, fiber deployment would have caused certain disturbances such as dust and noise, which are not compatible with the standard of excellent medical care that the Hospital Center of Provins wishes to provide to its patients.

The hospital Léon Binet wants to be at the leading edge of new technologies in order to better serve its patients.
It was thus the natural choice of Cailabs to propose the innovative AROONA-SMUX solution. This solution allows the recycling of existing multimode fiber infrastructure by increasing its capacity to transport very high bit rates.


Facilitation of the digitization project

Thanks to the passive AROONA-SMUX solution, the upgrade of limited fiber links was completed in just 3 hours, without any disturbance or interruption of services. The investment costs 3 times less than what the deployment of a new generation optical fibers would cost. Thus, the AROONA-SMUX solution enabled the digitization project of the Hospital Center of Provins by reducing costs and causing minimal disruption. The upgraded multimode fibers can now transport 4 x 10 Gb/s on fiber links that could previously only take up to 100 Mb/s, thereby enabling a 400x increase in fiber capacity. Patient information can now be easily communicated 24/7 for diagnosis and medical procedures from one building to another.

This significant increase in capacity leaves room for the Hospital Center of Provins to deploy more services in the near future to better serve their patients. For instance, billing and security systems, broadband connectivity and entertainment services for patients can be made more accessible.
