High-density, low-latency optical modules designed for immediate deployment in Belgrade data center switches, enterprise SANs, and telecom aggregation hubs.
As the economic, financial, and technology capital of Serbia, Belgrade has emerged as the premier ICT hub of South-Eastern Europe. Driven by major infrastructure developments in New Belgrade (Novi Beograd), the expansion of state-of-the-art carrier-neutral data centers, and massive national broadband digitization initiatives, local enterprise networks and telecom operators are transitioning rapidly from traditional 10GbE architecture to 25GbE Ethernet and 32G Fibre Channel (32GFC) standards.
Major telecom service providers including Telekom Srbija, Yettel Serbia, and A1 Srbija are expanding 5G fronthaul/midhaul deployments while upgrading backhaul backbone bandwidth. Concurrently, banking hubs, cloud providers, and government cloud facilities in the Belgrade Metropolitan Area require ultra-reliable, power-efficient, and low-latency SFP28 optical modules to handle exponentially growing East-West server traffic and Storage Area Network (SAN) data transfers.
25G SFP28 provides 2.5 times the bandwidth of 10G SFP+ utilizing the exact same physical form factor, dramatically improving rack unit density in Belgrade data centers.
Sub-1.0W power consumption per port significantly lowers operating expenditures (OPEX) and cooling requirements for dense server architectures.
Fully coded and tested for flawless interoperability with Cisco, Arista, Juniper, Dell, Huawei, MikroTik, and Brocade hardware deployed in Serbia.
The SFP28 (Small Form-factor Pluggable 28) transceiver module is engineered specifically for high-speed transmission at 25Gbps (Ethernet) and 28.05Gbps to 32Gbps (Fibre Channel). By implementing single-lane Non-Return-to-Zero (NRZ) signaling, SFP28 technology avoids the complex Forward Error Correction (FEC) overhead and higher latency inherent to legacy multi-lane solutions, rendering it the optimal choice for high-frequency trading, real-time telemetry, and cloud virtualization in Belgrade enterprise environments.
For Storage Area Networks (SAN), 32G Fibre Channel SFP28 modules provide double the throughput of 16G FC while maintaining seamless backward compatibility. Our modules feature advanced Digital Diagnostic Monitoring (DDM/DOM) interfaces via I2C, enabling real-time surveillance of optical output power, receiver sensitivity, laser bias current, module operating temperature, and supply voltage.
