MikroTik 10G Single-Mode SFP+ Module Pair, 10 km

The MikroTik S+2733LC10D is a pair of industrial-grade 10G SFP+ modules designed for single-mode fiber links over distances of up to 10 km. The modules are intended for networks that need 10G optical connectivity while using only one fiber strand between endpoints. By transmitting and receiving on different wavelengths, 1270 nm and 1330 nm, the pair supports bidirectional communication over a single fiber path. This helps reduce fiber requirements in installations where available fiber strands are limited or where the existing cabling needs to be used more efficiently. The SFP+ format makes the modules suitable for compatible 10G SFP+ ports, while the Duplex LC connector provides a standard optical interface for integration into structured fiber infrastructure.

The single-mode design supports longer-distance links compared with short-range multimode connections, making the module pair suitable for building-to-building links, network aggregation points, ISP infrastructure, and other deployments where distance and fiber availability matter. S+2733LC10D is positioned as an affordable alternative to the XS+2733LC15D module pair for customers who do not require 25G SFP28 support. It offers a practical choice for 10G networks that need reliable single-mode connectivity without moving to a higher-speed optical module class.

The S+2733LC10D module pair includes built-in digital diagnostics monitoring, allowing important operating parameters to be checked during use. These diagnostics cover optical power, voltage, temperature, laser bias current, and other key values related to module operation. This gives network administrators a clearer view of the optical link than basic connection status alone and helps identify abnormal activity or cases where configured operating limits have been exceeded. Diagnostic data is useful when planning maintenance or future network upgrades. Instead of relying only on whether a link is active, technical teams can review real operating values and better understand how the fiber connection is performing.

This can help with decisions about inspection, replacement, or capacity planning in networks where optical links are part of important infrastructure. The optical characteristics include transmitter output power from -8.2 to +0.5 dBm and receiver sensitivity down to -14.4 dBm. These values describe the optical signal levels the modules are designed to work with across their supported 10 km single-mode range. Combined with DDM support, they provide practical visibility for maintaining a stable 10G fiber link in service provider, enterprise, and infrastructure environments.
