18Lifetime Of Network Equipment
- Cabling itself has an average lifetime of 12
to 15 years - Capable to serve about 3 generations of
switchingEquipment - Capable to serve about 4 generations of PC
hardware - Probably even 5 generationsof software!
- Planning for a fast and futureproof network
starts with the investment of a strong
cablingsystem
19Why 10 Gigabit ?
- First edition From June 1976. (3 Mbps)
- IEEE released first 802.3 standard in 1983, which
defined10 Mbps - For every 4 years the speed has increased tenfold
- Eventually providing us with 10 Gigabit/s over
Fiber at the beginning of this millennium - Timely to its 30th anniversary, Ethernet
transmits electrical data signals 10000 times
faster than it initially started - What else can we expect to come.???
2010 Gigabit Backgrounds
Service Speed Bandwidth
Ethernet 10 Mbit/sec 10 MHz
Fast Ethernet 100 Mbit/sec 100 MHz
Gigabit Ethernet 1000 Mbit/sec 250 MHz
10 Gigabit Ethernet 10.000 Mbit/sec 417 MHz
2110 Gigabit Ethernet
- Example 10 Gigabit Ethernet
- Needed bandwidth about 500 MHz
- Existing Cat 7 will be new Cat 6a
- Existing installations have not enough bandwidth
- Exception
- All Cat 7 installations!
- All real shielded Cat 6 installations
- Best evidence
- Independent certification
22How 10 Gigabit Ethernet Work ?
- Another factor is channel capacity
- The capacity of a channel calculated according
Shannons law is the figure used to confirm
performance for 10GBASE-T channels
C is the achievable channel capacity B is the
bandwidth of the line S is the signal input IL
is the insertion loss of the transmission line
AXT is Alien Crosstalk BN is Background noise
23Why are noises critical today?
- Logic Signals smaller in each generation
- More electrical pollution
- Conclusion
- Signals extreme weak
- Systems and components need high suppression
- Or good S/N ratio by reducing the noise sources
24EMC and Background Noise
- TV, Radio stations
- Operating in the range of 10 Gigabit
25Shielded System
Pairs in metal foil NEXT and ANEXT background
noises Overall braid ANEXT and background
noises Both shields cover the whole frequency
range!
26Shielded System Installation
27Shielded System Installation
- Components before installation 2 only.
- Steps during installation 4 only.
- Dimensions SL profile. (High density).
- Dust cover Integrated.
- EMC 360 degree EMC cover for the cable
- EMC completely closed housing
28Shielded System Installation
- UTP systems needs separation to meet requirements
for 10 Gigabit Ethernet - As well if mixed with power cables!
Type of installation Distance A Distance A Distance A
Without divider or non-metallic divider Aluminium divider Steel divider
Unscreened power cable and unscreened IT cable 200mm 100 mm 50 mm
Unscreened power cable and screened IT cable 50 mm 20 mm 5 mm
screened power cable and unscreened IT cable 30 mm 10 mm 2 mm
screened power cable and screened IT cable 0 mm 0 mm 0 mm
- Recommendation Metallic cable ducts and steel
dividers
29XG Fiber Optic System
30The Migration Path
- LAN platforms moving from 100 to 1000 Mb/s
- LEDs cannot support high-speed platforms
- Need laser sources
- Lasers being deployed on multi-mode fibers
- 1000Mb/s (Gigabit Ethernet)
- Supports several 100Mb/s users
- 1000Mb/s is wildly popular
- Supports several switched 100Mb/s users
- Minimal price point difference over 100Mb/s
- Driving 1G to the users
31The Migration Path
- Wheres the migration path now?
- Single-mode lasers and fibers are expensive
solutions for LANs - Need to cover LAN distances using LAN fiber
- 300m for riser and centralized cabling
- Multimode fiber
- Low cost sources and electronics
32Overfilled Launch Laser Launch

35Why Multimode Fiber Optic
- Preferred Media for Local Area Networks
- Lower precision alignments
- Lower cost connectors
- Easier termination
- Lower Cost Installations
- Standards support
- TIA
- ISO
- Lower Cost Sources (850nm VCSELs)

- Is 10G enough?
- Upgrade path needed?
- What distances need to be supported?
- What cabling is installed?
