Tunable DWDM Transceivers

Lumentum’s tunable DWDM transceivers provide high-performance, cost-efficient optical connectivity for metro, access, and wireless transport networks. Available in T-SFP+ and T-SFP28 form factors, these C-band tunable modules support data rates from 10G to 25G with transmission distances up to 80 km. Built on Lumentum’s field-proven sampled-grating distributed Bragg reflector (SG-DBR) laser platform, they deliver precise wavelength control, low chirp, and excellent stability across standard and industrial temperature ranges. Tunable DWDM modules simplify inventory and deployment by replacing multiple fixed-wavelength optics with a single flexible solution. Designed for SONET/SDH, Ethernet, Fibre Channel, and 5G wireless applications, Lumentum’s tunable SFP+ and SFP28 products combine proven reliability, low total cost of ownership, and broad interoperability to enable agile, scalable optical networks.
