«I am pleased that a good university such as the Gdański Uniwersytet Medyczny
is going to have state-of-the-art research and science centers. Without them, medicine
simply would not advance.»

of the first part of the Centrum Medycyny Nieinwazyjnej (CMN).
buildings. In their place, the construction
companies erected the six-story CMN – starting
with the bunker for radiation therapy and
ending with the bridges to the equally new
Centrum Medycyny Inwazyjnej (CMI).
Multifunctional LAN
Uninterrupted data traffic plays a significant
role in this medical environment. Enormous
amounts of data are generated during
diagnoses, treatments and in laboratories.
This includes high-resolution tomography
images, radiological images and other data
from analysis and visualization procedures.
The radiology archive of a university hospital
can be several hundred terabytes in size. This
information must be available at all times
for consultations, research, intensive and
emergency care.
Increasingly, physicians are exchanging information
with each other and with the research
industry – locally and internationally via cloud
and telecooperation. To do so, they require

networks which can transfer several Gigabit/s
loss-free. The 6,000 medical students at the
GUM expect powerful equipment for digitized
training: PC workstations, fast WLAN,
broadband connections.
Sensitive medical devices and high-frequency
signal transmission require continuous shielding.
Discharge at plug connections must be
avoided, especially in the vicinity of patients
and monitoring devices.
The university clinic manages the data of
hundreds of thousands of patients. Active
and passive data protection has to be
guaranteed for these patients from the LAN
outlet to the data center. Furthermore, clinics
have to be prepared for comprehensive
digitalization. The buzzword for the future is
«smart hospital».
Network isolator
A network isolator ensures galvanic separation
in Ethernet-based networks. It interrupts
electrically conductive connections
between the periphery and the devices.
This is a precautionary measure to protect
patients and sensitive medical technology.
The reason is that current must not flow
over a patient’s body in case touchable
conductive parts of the device come into
contact with the patient. A network isolator
prevents currents from building up while
at the same time enabling virtually lossless

Make way for 10 Gigabit/s
The data network of the Centrum Medycyny
Nieinwazyjnej (CMN) at the Gdański
Uniwersytet Medyczny (GUM) is based on
the standard star topology model. In both
construction phases, the infrastructure
consists of fiber optic cabling for the backbone
and risers, and double-shielded copper
cabling for the floors.
Fiber optics:
– Backbone: OS2/OM4 cables, 96 fibers
– Risers: OS2/OM4 cables, 48 and 24 fibers
– Patch panels: Unirack2 OS2/OM4
(190 pcs.)
Copper:
– Horizontal cabling on the floors
– Installation cables: Cat. 7 S/FTP for
1,000 MHz (1,300 km)
– Patch panels: 1U with 24 or 48 Cat. 6 A
ISO/s modules (560 pcs.)
– Outlets: Cat. 6 A
ISO modules, FM45

connectors, protection class IP54
(20,730 pcs.)
The 104 racks with 750 patch panels can be
retrofitted with the infrastructure management
system R&MinteliPhy.
SafeLine network isolators from R&M ensure
galvanic separation of electrical equipment
close to the patient beds in accordance
with IEC 60601-1.
The three-level R&M security system with
mechanical protection of the connections
prevents manipulations and patch errors.
