Dorelink
Enterprise-grade optical transceivers configured and certified for high-performance networks in São Paulo and global markets.
The strategic nerve center of South America's digital economy requires robust, latency-sensitive optical solutions.
São Paulo is the largest telecommunications and data center hub in Latin America (LATAM). With key clusters in Barueri, Tamboré, Campinas, and Santana de Parnaíba, the state hosts hyperscale facilities managed by global leaders such as Equinix, Ascenty, Scala Data Centers, and ODATA. These hubs process petabytes of traffic daily, driving the demand for next-generation network infrastructures.
As networks face unprecedented pressure from cloud migrations, edge computing, and real-time banking applications centered in Faria Lima, legacy 10G networks are fast becoming bottlenecks. Transitioning directly to 100G can be capital-intensive for intermediate aggregation layers. 25G and 32G SFP28 transceivers present an ideal upgrade path. By leveraging the same physical footprint and cabling layouts as 10G SFP+, SFP28 modules deliver 2.5 times the bandwidth without requiring massive re-cabling investments. In São Paulo's competitive colocation landscape, this efficiency translates directly into cost savings and rapid service deployment.
Delivering high-performance components backed by extensive R&D and localized technical support.
Operating a manufacturing infrastructure in China allows us to leverage scale and R&D efficiencies. Dorelink provides optical transceiver modules engineered to perform reliably under demanding operational loads. Our team of 120 professional R&D engineers continuously monitors global specifications to ensure our transceivers align with evolving standardizations.
Our 25G and 32G SFP28 transceivers are optimized for diverse deployment scenarios across Brazil's digital ecosystem:
Internet Service Providers (Provedores de Internet) in São Paulo state are extending fiber reaches using 25G BiDi and CWDM/DWDM SFP28 modules. These options enable bidirectional transport over a single fiber or passive multiplexing, deferring the high cost of laying new optical fiber lines across dense urban routes.
For investment banks and financial institutions in the Faria Lima corridor, latency is a critical performance indicator. We supply high-stability 32G SFP28 Fibre Channel modules designed for high-density storage area networks (SAN), ensuring rapid data replication and low-latency transactional execution.
