Xelivor
Industrial-grade optical transceivers engineered for seamless integration with Hirschmann, Moxa, Cisco, and legacy Fast Ethernet switches across Coimbra’s industrial zones.
Navigating the strategic role of 155Mbps Fast Ethernet and 622Mbps ATM/SDH transceivers in Portugal's tech capital.
As the historic academic heart of Portugal and a rapidly growing technological beacon in Central Portugal, Coimbra is home to sprawling innovation ecosystems such as Coimbra iParque, the technology transfer centers of the University of Coimbra, and major industrial logistics corridors in Pedrulha and Taveiro. Network reliability across these sectors requires rock-solid hardware infrastructure. While hyper-scale data centers gravitate toward 100G and 400G interfaces, legacy industrial networks, municipal telemetry, sub-station automation, and specialized telecommunications backhauls in Coimbra heavily depend on standardized 155Mbps (100BASE-FX / STM-1) and 622Mbps (OC-12 / STM-4) Small Form-factor Pluggable (SFP) modules.
Substation automation throughout the Coimbra district (compliant with IEC 61850 standards) utilizes 155M SFP optical transceivers for zero-EMI noise immunity over multi-kilometer fiber runs. High-voltage electrical environments, such as those operated by regional utility grids (EDP Distribuição connections), cannot tolerate electromagnetic interference. Optical fiber interfaces operating at 1310nm Fast Ethernet speeds provide precise timing synchronization, determinism, and high mean time between failures (MTBF), safeguarding critical electrical distribution networks across Portugal.
Technical benchmarks, laser physics, and MSA Multi-Source Agreement compliance for mission-critical deployments.
Our 155M and 622M SFPs utilize advanced 1310nm/1550nm Fabry-Perot (FP) or Distributed Feedback (DFB) laser transmitters paired with high-sensitivity PIN-TIA (Transimpedance Amplifier) or APD (Avalanche Photodiode) receivers. This optics combination achieves an extraordinary Bit Error Rate (BER) better than 10-12, critical for real-time SCADA and telecommunication traffic.
For fiber-constrained urban layouts in Coimbra’s historic city center, single-strand Bidirectional (BiDi) SFP transceivers combine 1310nm-TX/1550nm-RX and 1550nm-TX/1310nm-RX onto a single LC optical strand. Wavelength Division Multiplexing (WDM) cuts fiber cabling infrastructure expenses by 50% while expanding network bandwidth seamlessly.
Real-time DDM/DOM monitoring provides network administrators in Coimbra visibility into optical output power, receiver optical power, laser bias current, module temperature, and supply voltage. Early anomaly detection prevents unplanned network downtime in mission-critical environments.
Engineered for high compatibility with Hirschmann, Moxa, Cisco, Huawei, Alcatel-Lucent, and Allied Telesis switches deployed in Coimbra.

Field-proven deployments tailored to the topological and industrial operational requirements of Portugal's Central Region.
Coimbra’s urban infrastructure upgrades demand resilient video surveillance backhaul across historical districts and modern traffic networks. Using 155M Simplex BiDi SFPs, local systems integrators maximize existing fiber plant capacities, feeding HD video signals from remote monitoring nodes back to central operations without incurring fresh trenching costs.
Manufacturing complexes in Pedrulha rely on rugged Hirschmann DIN-Rail switches and Moxa EtherDevice equipment. Our 100BASE-FX (2km MMF) and 100BASE-LX SFPs are pre-coded with manufacturer-specific EEPROM signatures, guaranteeing 100% plug-and-play interoperability without triggering port errors or switch alarms.
Regional railway signaling (such as along the Linha do Norte connecting through Coimbra-B) utilizes 622Mbps (STM-4/OC-12) optical transceivers for synchronous optical networking (SONET/SDH). Extended temperature range SFPs (-40°C to +85°C) ensure operational readiness under extreme climatic variances.
Connecting specialized university laboratories with the Coimbra Hospital and University Centre (CHUC) requires galvanically isolated, high-reliability legacy fiber links. Our 155M SMF optical modules deliver long-distance secure physical-layer data transmission resistant to eavesdropping and localized electrical surges.
