Why are there no applications @ 1400nm?
ANSWER: HIGH LOSS!!!
1350nm to 1450nm (E-band)
traditionally no operation due to high loss.

•1280 to 1625nm

•Commonly known as “Water Peak”
•Ordinary singlemode fiber (G.652 compliant fiber) suffers from
this problem.

− 9um SINGLEMODE
− G.652.C compliant
− no water peak
− removes Hydroxl ions from fiber
− Increases capacity per Fiber
− Due to elimination of water peak causing high loss
− 60% more usable wavelengths
− Maximizes support for CWDM / DWDM
− Low Cost Future Proofing for Next Generation Equipment

Data center considerations
• Fast installation
•Installer spend less time in data center
•shorter cut-over
• High Performance
•minimise down-time
•Low loss allow for flexibility in design
• Minimise space used
•Data center high cost due to supporting facilities
• No chemicals
•confined areas - fumes difficult to disperse
•prevents accidental fires / damage
