The MikroTik S-55DLC80D is an SFP module with industrial durability, designed for long-distance fiber optic connections. It provides stable and high-speed data transmission over distances up to 80 kilometers, making it an ideal solution for inter-city connections, campus networks, or infrastructure in challenging geographical conditions. Thanks to its compact SFP form factor, it can be easily integrated into all compatible network devices, allowing you to enhance your existing infrastructure with high-performance fiber connections. The technical strengths of this module stand out in its durability and high performance, especially in harsh environmental conditions. Its ability to operate flawlessly in the industrial temperature range (-40°C to +70°C) guarantees reliability in both freezing cold and extreme heat. With a data rate of 1.25 Gbps and a wavelength of 1550 nm, it provides maximum efficiency and minimal signal loss over single-mode fibers. Additionally, the Dual LC UPC connector ensures a secure and low-loss optical connection. The MikroTik S-55DLC80D is particularly suitable for scenarios requiring high bandwidth and where distance is critical, such as remote offices, data center interconnections, or surveillance systems. It creates a stable network backbone over distances that standard modules cannot reach, in power transmission lines, transportation networks, or communication infrastructure in rural areas. It is fully compatible with all MikroTik routers and switches with SFP or SFP+ slots, making it extremely easy to expand your existing MikroTik ecosystem.
