Lumentum Holdings announced limited sampling of its new 400/800G ZR+ L-band pluggable transceivers.
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.
Lumentum also announced general availability of its 800G ZR+ C-band module.
Both products will be showcased in live demonstrations at the 2025 Optical Fiber Communications Conference and Exhibition (OFC) on April 1-3.
