More photonic layer flexibility required

• Photonic layer restoration • Fewer IP and OTN protection interfaces by introducing photonic layer restoration as

‘second-line-of-defense’

• Network automation • Automated end-to-end capacity provisioning

• Network ‘defrag’, network load balancing and maintenance switching

• Dynamic and efficient capacity allocation • Optimal allocation of spectrum for 100G, 400G and 1Tbps

3 Critical Requirements to “Future Proof” the Network

and Support Beyond 100Gb/s

Flexible Channel

– 12.5GHz granularity or better

– Including a Flex Optical Channel Monitor 150GHz 50GHz 75GHz

Higher WSS Isolation

– 16QAM requires 5 – 7dB greater isolation

– Target 45dB or higher

400Gb/s will require higher OSNR

– Need Raman amplification

– Need less ROADM node loss

“Tx Array”

EDFA array

• MCS is intrinsically high loss – EDFA array required

• Add-drop only - performance relaxation is possible (eg. gain flatness/tilt, transient

control)

• Conventional EDFA design with discrete pumps and passives (isolators, 980/1550

WDM, taps. PDs) yields reasonable cost and footprint • Compatible with 2 slot EDFA array+ MCS blade

• Cost reduction / improved density through passive integration and pump sharing
