LWAZI PM delivers industry‑leading CWDM/DWDM multiplexers, arrayed waveguide gratings, reconfigurable OADMs, EDFA and Raman amplifiers, OTN transport systems, and data‑centre interconnect modules. Our solutions are engineered for high‑capacity backbone, regional aggregation, and low‑latency 5G fronthaul/backhaul, serving network operators across Africa and Europe.
Scalable WDM, optical amplification, and transport solutions for backbone, metro, DCI and 5G networks
High‑performance coarse and dense WDM mux/demux modules for short‑reach metro and long‑haul backbone. Available in 8‑, 16‑, 40‑ and 96‑channel configurations with ITU‑T grid compliance.
Athermal and thermoelectric AWG devices for 50GHz and 100GHz channel spacing. Ultra‑low PDL and excellent passband flatness for high‑density wavelength routing.
Reconfigurable optical add‑drop multiplexers with wavelength‑selective switches (WSS) for flexible grid and colourless/directionless/contentionless (CDC) node architectures.
Erbium‑doped fibre amplifiers (EDFA) and distributed Raman amplifiers for C‑band and L‑band. Booster, pre‑amplifier, and in‑line models with gain up to 35 dB and noise figure < 4.5 dB.
Optical transport network (OTN) equipment supporting ODU0 to ODU4, with integrated switching, multiplexing, and FEC. Designed for carrier‑grade metro and backbone networks.
Compact data‑centre interconnect (DCI) boxes and 5G fronthaul/backhaul transponders, offering low‑cost, low‑latency wavelength conversion and aggregation for edge and cloud data centres.
From transcontinental backbone to metro aggregation and 5G edge – our optical solutions fit every network layer
DWDM terminals with EDFA/Raman amplification and ROADM nodes enable ultra‑high‑capacity transmission over thousands of kilometres with coherent detection and advanced FEC.
CWDM and DWDM ring topologies with OADM and OTN switches provide flexible bandwidth grooming and restoration for urban and regional networks.
Compact, low‑power DCI platforms with coherent DWDM optics connect multiple data centres over dark fibre, supporting 100G to 400G with minimal latency.
WDM‑based fronthaul and backhaul modules with CPRI/eCPRI mapping, enabling high‑density, low‑latency connectivity for 5G radio access networks.
Cost‑effective CWDM and passive optical splitters for campus backbone and building‑to‑building links, supporting 10G to 100G connectivity.
Hardened WDM and OTN equipment for power grid, railway, and oil/gas pipelines, offering extreme temperature tolerance and high reliability.
