Discover the transformative power of coherent pluggable optics in the realm of optical communications networks. Traditionally, transceivers have played a vital role in these networks, but now we are witnessing a paradigm shift. Coherent pluggable optics are assuming new responsibilities, especially in router-to-router links for data center interconnect and service provider IP over DWDM, as well as IP/optical layer integration. The significance of pluggable optics in open line systems is increasingly evident, revolutionizing network infrastructure.
Moreover, transmission rates are soaring from 400GbE to 800GbE, with an astounding 1.6TbE on the horizon. This webinar will delve into these trends across various applications and explore the optimal utilization of current and emerging modules. Join us as we unravel the potential of cutting-edge technology in optical communications networks.

MULTIPLE WAYS TO DELIVER A PLUGGABLE 100G COHERENT
Comparisonof QSFP-28 vs QSFP-DD
Possible module formats for 100G ZR coherent
QSFP-28 QSFP-DD
Pros
✓ Low power consumption(≤ 6W)
✓ Wide deploymentin legacy access equipment
✓ Compatiblewith QSFP-DDslots
✓ Nonew sub-componentdevelopmentneeded(can
makeuse of availableDSPsand lasers)
Cons
χ All major buildingblocks(DSP, Laser, COSA) need to
be purpose-builttomeet the stringentrequirements
on footprintandpower consumption
χ Higher power consumption(≥13W)
χ Requires upgradeof access equipment, as the legacy
is basedon QSFP-28 slots

QSFP-28 100G ZR COHERENT IS COMING TO EDGE NETWORKS
7
• QSFP-28 100ZR optics have an
advantage over QSFP-DD:
– Much lower power consumption
– The ability to plug into existing hardware
– Usable in both QSFP-28 and QSFP-DD slots
• 100ZR is an enabler for cost-effective
upgrades at the edge
– Enabling the transition from 1G to 10G in
access networks
– By transitioning from grey / CWDM to
DWDM, a higher capacity can be transported
per fiber, without the need to install / lease
