In the heart of the global digital economy, London remains the "Data Capital of Europe." From the financial powerhouse of the City of London to the burgeoning tech clusters in Shoreditch (Silicon Roundabout), the demand for ultra-high-speed, low-latency 40G QSFP+ modules has never been higher. As businesses transition from 10G legacy systems to 40G and 100G architectures, the role of a reliable 40G QSFP+ module exporter becomes critical.
The Docklands (Telehouse, Equinix) and the M4 Corridor (Slough) represent the backbone of UK's internet infrastructure. Our 40G QSFP+ modules are engineered to meet the rigorous standards of these "Tier 4" data centers, ensuring that London-based enterprises can maintain 99.999% uptime for their global operations.

With over 12 years of industry experience and 7 years of specialized export history, Dorelink Optical Communications Co., Ltd. has mastered the nuances of optical physics and high-speed signaling. Our team of 120 R&D engineers ensures that every 40G QSFP+ module—whether SR4, LR4, or BiDi—exceeds IEEE 802.3ba standards.
Our manufacturing process in China leverages Smart Factory 4.0 principles. By integrating automated optical testing, robotic assembly, and real-time big data analysis of bit-error rates (BER), we provide a level of supply chain resilience that traditional manufacturers cannot match. This efficiency allows us to provide London-based clients with superior quality at highly competitive wholesale rates.
We understand that a single module failure can cause catastrophic downtime for a London trading firm. Therefore, we employ a 45-person professional QC team. Every unit undergoes rigorous aging tests, temperature cycling, and compatibility verification with major brands like Cisco, Arista, Juniper, and Mellanox.
While 100G and 400G are growing in the hyperscale space, the 40G QSFP+ module remains the workhorse for enterprise campus networks and medium-sized data centers across the UK. Key trends we observe in the London market include:
As a leading manufacturer, we bridge the gap between high-volume Chinese production efficiency and the strict quality requirements of the European market. Our 18,500㎡ facility is optimized for agile manufacturing, allowing us to pivot production to meet sudden spikes in demand from the UK market. With 85 new product releases annually, we stay at the absolute cutting edge of fiber optic innovation.
SR4 (Short Range) uses multimode fiber (MMF) for distances up to 150m, typically used within a single data hall. LR4 (Long Range) uses single-mode fiber (SMF) to reach up to 10km, ideal for interconnecting different buildings across London boroughs.
Yes, we are a professional exporter with 7 years of experience in international logistics. We offer DDP/DAP shipping terms to London and the rest of the UK, ensuring smooth customs clearance and rapid delivery (typically 3-5 business days via DHL/FedEx).
Absolutely. Our R&D team performs extensive firmware optimization. Each module is coded and tested specifically for the client's host equipment to ensure 100% compatibility and DOM (Digital Optical Monitoring) functionality.
By purchasing from Dorelink, you gain "Information Gain"—direct access to technical data and customization that middle-man distributors can't provide. You also benefit from factory-direct pricing and Industry 4.0 manufacturing precision, which reduces the total cost of ownership (TCO).
