Explore our top four optical transceivers, highly requested for enterprise cores and data distribution facilities across Paris, Marseille, and Lyon.
France is undergoing a rapid, structured digital transformation accelerated by the nation's "Plan France Très Haut Débit" and EU-backed sovereign data policies. Paris, currently ranking as one of the top datacenter markets in Europe (alongside London, Amsterdam, and Frankfurt), continues to add massive MW-capacity sites. At the same time, Marseille acts as a global gateway, serving as a termination point for major international subsea optical systems linking Europe with the Middle East, Asia, and Africa.
To support this high-performance layout, network engineers and procurement offices across France require highly specialized fiber communication hardware. The shift towards 100G QSFP28 optical modules is driven by the need to handle massive traffic flows in sovereign clouds, high-frequency trading networks, and industrial IoT environments. The demand is not just for generic hardware, but for optical assemblies that guarantee compliance with European energy directives and strict signal latency standards.
A look into how 100G QSFP28 modules utilize advanced wavelength multiplexing to deliver high throughput across single-mode and multi-mode systems.
Ideal for short-range fiber runs up to 100 meters using OM3/OM4 cabling inside regional colocation centers. Utilizing MTP/MPO or Duplex LC connectors with wavelength divisions to simplify cabling architecture.
Designed for intermediate links up to 2km (PSM4) or 10km (LR4) over traditional single-mode fiber (SMF). They provide direct optical feeds for high-throughput switches with minimum attenuation.
For cross-region backhauling over 40km (ER4) up to 80km (ZR4). Perfect for connecting regional enterprise sites across cities in Western France without requiring active regenerators.
| Transceiver Type | Connector Type | Fiber Type | Operating Wavelength | Max Transmission Distance | Typical Application in France |
|---|---|---|---|---|---|
| 100GBASE-SR4 | MTP/MPO-12 | Multimode (MMF) OM3/OM4 | 850nm | 100m | ToR Switch-to-Server connections in Paris Data Centers |
| 100GBASE-SR SWDM4 BiDi | Duplex LC | Multimode (MMF) OM4 | 850nm to 940nm (BiDi) | 100m | Optimizing existing duplex LC fiber legacy paths |
| 100GBASE-PSM4 | MTP/MPO-12 | Single-Mode (SMF) | 1310nm | 2km | High-density inter-row datacenter fabrics |
| 100GBASE-LR4 | Duplex LC | Single-Mode (SMF) | 1295nm to 1309nm (LAN-WDM) | 10km | Metropolitan area networks and enterprise backbones |
| 100GBASE-ER4 / ER4L-S | Duplex LC | Single-Mode (SMF) | 1295nm to 1309nm (WDM) | 40km | Inter-city data networks and regional distribution rings |
| 100GBASE-ZR4 | Duplex LC | Single-Mode (SMF) | 1310nm WDM | 80km | Ultra-long span rural telco fiber networks |
French enterprise networks, especially those managed by regulated institutions or top telco networks like Orange, SFR, Iliad (Free), and Bouygues Telecom, enforce strict infrastructure standards. Equipment must not only display the CE marking but also conform strictly to the RoHS (Restriction of Hazardous Substances) and WEEE directives to support corporate sustainability initiatives.
Our manufacturing and assembly plant enforces a rigorous 100% triple-test routine on every transceiver and cable system before shipping. Using advanced test beds featuring modern host switches from Cisco, Arista, Juniper, and Huawei, we program custom microcode into our 100G QSFP modules to prevent port errors, link flapping, and DDM (Digital Diagnostics Monitoring) reporting discrepancies.
Established in 2012 in Hong Kong as a high-technology communication enterprise, Kocent Optec is a manufacturer and provider of optical termination systems.
By combining our manufacturing capabilities with modern engineering, we deliver optical networking solutions directly to your operations. Many of our OEM and ODM assemblies have successfully won telecom operator tenders globally and satisfy end-user requirements for leading international carriers.
Our main terminal telecom operators include: SingTel, Vodafone, America Movil, Telefonica, Bharti Airtel, Orange, Telenor, VimpelCom, TeliaSonera, Saudi Telecom, MTN, Viettel, Bitel, VNPT, Laos Telecom, MYTEL, Telkom, Telekom, Entel, FiberTel, StarFiber, Ooredoo, Beeline, Azercell.
From single-mode components and tactical deployment cabling to high-density distribution frames, we supply the complete optical path.
As data loads increase, French infrastructure teams are planning migration paths from 100G architectures to higher speed topologies.
The progression toward 200G (QSFP-DD/QSFP56) and 400G interfaces is accelerating in core routing backplanes across EU hub networks. While 100G QSFP28 remains the workhorse for top-of-rack downlinks and enterprise distribution, migrating to 200G and 400G formats requires careful validation of power limits and cooling budgets.
Kocent Optec Limited integrates transceiver designs with active silicon photonics integration. This setup ensures that when French data hubs migrate, legacy fiber networks can support higher data rates with minimal changes to physical installations.
