High-performance duplex and single-mode optical modules engineered for telecommunications, smart city networks, and enterprise backhaul in Coimbra.
Coimbra, historically recognized as Portugal's intellectual capital and the primary economic hub of the Centro Region, is currently experiencing an unprecedented technological resurgence. As traditional industries digitize and high-tech research centers expand outward from the prestigious University of Coimbra (Universidade de Coimbra - UC), Instituto Pedro Nunes (IPN), and Coimbra iPARQUE, the requirement for robust, low-latency, and high-throughput optical communications has escalated exponentially.
The demand for intermediate-speed optical interfaces—specifically spanning from 2.5 Gbps to 6.144 Gbps (CPRI/eCPRI & 2.5G/5G Ethernet standards)—is driving network upgrades across local municipal networks, university campus backbones, regional telecom mobile towers, and smart industrial parks. Whether connecting remote radio heads (RRH) to baseband units (BBU) in 5G wireless fronthaul architectures or providing multi-gigabit backhaul for GPON/XGS-PON optical line terminals (OLTs) in the Mondego Valley, optical transceivers serve as the critical hardware foundation for digital expansion.
To serve systemic networking demands across Coimbra and broader Iberian integration, system integrators, municipal IT architects, and telecommunications contractors require suppliers capable of providing rigorous reliability, Multi-Source Agreement (MSA) compliance, deterministic optical performance, and seamless OEM compatibility without prohibitive regional distributor price markups.
In modern optical networking, the 2.5G to 6G frequency spectrum occupies a crucial technical niche. While 10G, 40G, and 100G transceivers dominate large-scale data center core backbones, 2.5G (2.5 Gbps SFP/SFP+) and 6G (6.144 Gbps CPRI Option 6) modules deliver the optimal balance of power efficiency, thermal stability, transmission reach, and cost performance for access networks and cell-site backhaul.

| 2.5G SFP BIDI (WDM) | 2.5 Gbps Simplex | 1310nm/1550nm, 1490nm/1550nm | Single Strand SMF 20km - 80km | Fiber-constrained rural links, municipal traffic light networks |
| CPRI Option 3 / 5 / 6 | 2.457G / 4.915G / 6.144 Gbps | 1310nm / 1270nm-1330nm CWDM | SMF Duplex/BIDI 10km - 40km | Mobile Fronthaul (MEO, NOS, Vodafone 4G/5G Base Station Towers) |
| 6G SFP+ Industrial | 5.95 Gbps - 6.144 Gbps | 1310nm / 1550nm EML | SMF 20km - 40km (-40°C~85°C) | Outdoor cell tower units across Serra da Lousã & Mondego Valley |
