Slide #26
Future Work- Network ExtensionOption 1Upgrading the Network to 10 gigabit once the new fiber cable is installed in Karolinska Huddinge
VV Bifrost
Karolinska Huddinge
Patch Cable
KI Solna
300 meters45
Kilometers
HS1 Operation Theatre
Distance
Attenuation 15-16 dB
Link Repaired!!!Less than
1dB
KI Bifrost
KTH Valhallavagen
Fiber Link
Total Attenuation 20-22dB
Expected Total Attenuation after new fiber is installed: 16 + 0.5 = 16.6 dB
Acceptable Attenuation for 1550nm XFPs = 19 dB
Link Budget Margin = 19- 16.5 = 2.5 dB
2.5 dB is good but
not suitable for long
term solution
Slide # 27
Future Work- Network ExtensionOption 2 Install a bifrost router in Karolinska Solna which will be suitable for long term solution and video conferencing can be performed from Solna as well.
Slide # 28
Future WorkBifrost Routing Performance
It’s a continuous process to be carried on to boost the
performance further with new equipments, Documentation on
our website will be helpful
NOC System
Evaluate and implement a mechanism for monitoring the live
HD video streams for HD video conferencing system
Maputo Network
Deploy similar network and NOC system in Mozambique NREN,
