Insights
Lumentum's introduction of 400/800G ZR+ L-band pluggable transceivers represents a significant technological advancement with substantial market implications. By extending operations into the L-band spectrum alongside the C-band, these modules effectively double the wavelength capacity of existing fiber infrastructure - a critical capability amid the global fiber shortage.
The dual-rate functionality of these transceivers is particularly valuable, delivering 800G transmission for shorter data center interconnect and metro applications while supporting 400G for extended long-haul deployments. This versatility optimizes both performance and reach, allowing network operators to maximize their infrastructure investments across various deployment scenarios.
What makes these modules especially compelling is their pluggable form factor enabling direct router-to-router connectivity, which eliminates intermediate transponder systems. This architectural simplification delivers considerable CAPEX and OPEX advantages by reducing equipment footprint, power consumption, and operational complexity.
With surging bandwidth demands from AI and ML applications straining networks globally, solutions that maximize existing fiber capacity without requiring new fiber deployment address an urgent market need. The transition from sampling to general availability also indicates Lumentum is executing well on its product roadmap, positioning the company to capitalize on the accelerating bandwidth demands driven by compute-intensive AI workloads.

The new L-band module extends transceiver operation into the L-band spectrum, effectively doubling the usable wavelength range and available fiber capacity. It delivers 800G data rates for data center interconnect (DCI) and metro applications, while supporting 400G data rates in long-haul deployments using quadrature phase shift keying (QPSK) for optimized reach and performance.
The 400G ZR++ L-band module will be demonstrated alongside the TrueFlex® Micro Twin 2x34 integrated C and L Wavelength Selective Switch (WSS), highlighting a comprehensive and cost-effective system-level solution.
“Lumentum brings its proven high-performance optics and integration expertise to the L-band to help customers scale their networks more efficiently,” said Marc Stiller, Lumentum vice president of Product Line Management. “By enabling both 800G and 400G data rates across a broader spectrum, we’re helping to unlock greater capacity on existing fiber infrastructure, supporting the surging demands of AI and cloud-based applications.”
Lumentum’s pluggable modules are designed for direct router-to-router connectivity, reducing overall system complexity and cost. Expanding access to fiber capacity is essential as data traffic driven by artificial intelligence (AI) and machine learning (ML) continues to grow at an unprecedented pace. Both the L-band and C-band modules help address global fiber shortages while enabling the rapid scaling of network transmission capacity.
