$LWLG Dr Lebby told investors that the 50Gbs protos are "on track" and his ECOC presentation was laudable, there were amazing detailed specs including 1V power, there was passing of rigid Telcordia GR-468 standards, there was announcement of proven scalability over 300% better than where legacy devices "top out"
These 3 Slides that tell Investors LWLG has true Next-Gen product ready to go!
Slide 45
Industry perception and reality…
• Industry perception
– We (the Industry) are stuck at ~35-50 Gbaud bandwidth. Everything else has to come from increasing complexity of modulation schemes and electronics
• Reality:
– We (LWLG) can use polymer modulators for 100 Gbaud or more!
– E.g. 100Gbps single lane NRZ, 400Gbps with 4 lanes NRZ, 800 Gbps with 4 lanes PAM4
• Industry perception
– Voltages will be high like other MZ modulators
• Reality:
– ~1V means we can eliminate drivers, use direct drive from CMOS
• Industry perception
– Polymer modulators are huge, stand-alone devices
• Reality:
– 5mm Mach-Zehnder fits into standardized transceiver footprints
– Hybrid integration possible with InP, Si photonics, etc. ?
Polymer modulators are the ticket to the next speed node…
Slide 22
Advantages for Polymer Modulators
• Advantages (LWLG material)
– Very high bandwidth (>100 Gbaud) potential
• Capability of 100Gbps NRZ, 200Gbps PAM4, 800 Gbps 16QAM, etc.
• Small size
– Very low voltage (~1V)
• Smaller, lower power drivers or complete elimination of drivers
• High electro-optic efficiency
• Low power
– Robust material
• Low insertion loss
• High stability
• High operating temperature
• Compatible with photonic integration
#Slide 17 (Complexities/Additional Costs All Legacy Technologies are forced to use for 400Gbs node)
• Advanced modulation requires a lot of additional electronics for digital signal processing (DSP)
• Dramatic increase in transceiver electronic content for PAM4
• Coherent requires even more DSP
• Pushback on number of lanes
• 4 is preferred over 8 for single-mode, 16 considered
only for multi-mode
