På vilket sätt påverkar Fluorerande växthusgaser miljön?
Fluorerade växthusgaser, varav de viktigaste är fluorkolväten (HFC), fluorkarboner (FC) och svavelhexafluorid (SF6), bidrar till den globala uppvärmningen och har mycket stor påverkan på växthuseffekten per viktenhet (global warming potential, GWP).
Vilken gas får man mörk röst av?
Anledningen till att man får pipig röst när man har andats in helium är att ljudets hastighet är mycket högre i helium än vad den är i luft. Om man andas in en gas som är tyngre än luften så får man en mörkare röst. Observara att det kan vara mycket farligt att andas in helium från ballonger.
Are HFC and FTTP really the same speed?
While FTTP has typically been labelled as being capable of conducting the fastest plans among the connection types, it is interesting to note that HFC and FTTP actually achieve very similar speeds. So what are the actual speeds to expect for HFC and FTTN?
What is the difference between FTTH and HFC?
FTTP can have a backup battery if you wish, you don’t need a modem for home phone and ping will be much better. GPON (FTTH) is also shared with your street. One GPON split only does 2.5Gbps and is shared amongst numerous houses (up to 128, but I don’t think NBN Co are using split ratios that high) Hfc also has no power backup.
What happened to the FTTN to FTTP shift?
With many consumers still confused on the FTTN to FTTP shift which was discussed back in June 2016 AFTER construction to the Fibre to the node network had started. The change to the policy was announced in June 2016 ” The FTTN roll-out will be phased out as soon as current design and construction contracts are completed”.
What is the backup capability of FTTP in emergencies?
There’s no backup capabilities or availability in emergencies. With FTTP you can have a battery or UPS at your residence keeping your connection going (Or a solar panel setup that allows continuance of power even in a blackout situation.) and the exchange can have it’s own large scale batteries/generator keeping things running for extended periods.
