ADVA Optical Networking's direct detect open optical layer is specifically designed for the ICP and CNP market. The new solution is a key expansion of the ADVA FSP 3000 CloudConnect™ platform and offers a compelling alternative for customers who want to avoid the expense of traditional coherent solutions. The direct detect technology is available in two distinct formats. It can either be bought as an Open Line System (OLS) in a disaggregated manner or as a complete solution that includes the terminal and the line system. One compelling feature of ADVA Optical Networking’s OLS is its SmartAmp™ technology that enables direct detect transmissions to be transported up to 100km.

Application Space
• Scalability
• Cloud-scale customers driving >20Tbit/s per fiber
• Majority of customers will need much less
• Space and power optimization has high value
• Simple design, no OTN, Ethernet services dominate
• Client equipment typically routers or Ethernet switches
• Do not want to deal with variants

Market Trends
• Customers driving pricing for
100Gbit/s services further down
• Currently not possible to meet with
16QAM coherent systems
• Coherent system capacity is overkill
for most of our customer base
Coherent has dominated but …
• Customers with minimal optical
knowledge levels
• Customers with small operations
teams
• Needs to be plug-and-play
… direct detect has its challenges

PAM4
• Pulse-amplitude modulation with four amplitude levels
• Simple “higher-order modulation” scheme
• Four distinct pulse amplitudes are used to convey the information
Amplitude levels 1, 2, 3, and 4 represented by two bits (“symbol”) 00, 01, 11, & 10,
respectively
Level 1
Level 2
Level 3
Level 4

PAM-4 – Benefits and Challenges
• Benefits
• Twice as bandwidth-efficient as conventional binary modulation (NRZ)
• Simple (direct detection)
• Lower power consumption and lower-cost optical transceivers than coherent
transceivers
• Challenges
• Higher OSNR requirement (more susceptible to noise)
• PAM4 restricted to short-haul systems of moderate capacity

• QSFP28 DWDM (non-tunable) pluggable optics (directly into switch/router)
• Dual-wavelength 2x 56Gbit/s PAM4 (non-tunable)
• Up to 4Tbit/s capacity in C-band
• Low power solution: ~4.5W
