Compatible 40G Long-Distance Optical Transceiver Supplier from Congo

Suppliers like FS, QSFPTEK, Fibrecross, and Arista offer compatible 40G long-distance optical transceivers that can be shipped to Congo, supporting distances from 10km up to 80km over single-mode fiber.Recommended Suppliers and Products1. FS (Fiberstore) FS provides a wide portfolio of 40G QSFP+ transceivers, including SR4, LR4, ER4, and PLR4 modules. Their long-distance modules support up to 40km over single-mode fiber, suitable for 40G Ethernet and Optical Transport Network (OTU3) applications. FS transceivers are tested for compatibility with major network equipment and come with warranty and certification support .2. QSFPTEK QSFPTEK offers Extreme QSFP-LR4-40G modules capable of 20km transmission over OS2 single-mode fiber. These modules feature LC duplex connectors, DOM/DDM monitoring, and are compatible with Extreme network devices, making them a cost-effective solution for high-performance 40G connectivity in enterprise and metro networks .3. Fibrecross (OEM & ODM Solutions) Fibrecross provides customizable 40G QSFP+ transceivers with variants including SR4, LR4, and ER4. They offer OEM/ODM services, allowing for firmware customization, branding, and tailored form factors. Their modules are compatible with a wide range of switches, routers, and servers, ensuring seamless integration into existing infrastructures .4. Arista Networks Arista offers QSFP+ universal transceivers for 40G operations over duplex multi-mode and single-mode fiber, with reach options up to 80km. Their modules are interoperable with IEEE 40GbE LR4 and LRL4 standards, suitable for data center interconnects, metro networks, and long-distance enterprise backbones .Considerations for CongoShipping and Import: These suppliers typically ship internationally, but users in Congo should confirm shipping options, customs clearance, and import duties.Compatibility: Ensure the selected transceiver matches the switch/router vendor and model in use. LR4 and ER4 modules are widely compatible, while ZR4 modules are recommended for distances up to 80km .Fiber Type: Single-mode fiber (OS2) is required for long-distance links beyond 10km. Multimode fiber is limited to shorter distances (up to 150m for SR4).Support and Warranty: Choose suppliers offering technical support and warranty, especially for long-distance deployments where reliability is critical.By selecting from these suppliers, network operators in Congo can deploy reliable 40G long-distance optical links for data centers, metro networks, or inter-campus backbones without migrating immediately to higher-cost 100G coherent systems .
