MikroTik HS-2733LC20D 1 25G WDM single-mode MiniGBIC module (SFP)

MikroTik HS-2733LC20D — SFP module kit for single-mode

For network specialists looking for a reliable and efficient solution for single-fiber optical connections, the MikroTik HS-2733LC20D delivers excellent performance with support for 1G and 2.5G transmission speeds. Thanks to BiDi (Bi-Directional) technology, which allows transmission and reception at different wavelengths (1,270 nm and 1,330 nm) over a single optical fiber, it reduces cabling requirements and optimizes infrastructure. With a range of up to 20 km over single-mode fiber, this kit is an ideal solution for expanding network capacity without the need to replace existing optics.

Optimization of single-fiber connections

Thanks to BiDi technology, the modules use a single optical fiber for bidirectional transmission, which significantly reduces cabling costs. 1G and 2.5G data rates support flexible deployment in a variety of network environments, from common applications to those requiring higher transmission capacity. Reliable range up to 20 km ensures stable connections even over longer distances.

DDM monitoring and network management

The integrated DDM (Digital Diagnostics Monitoring) function allows monitoring of key parameters such as optical power, temperature, supply voltage and laser bias current. These diagnostics help detect potential problems before they cause outages and enable maintenance planning based on real data. This makes operational management more efficient and reliable.

Electrical characteristics and signal loss signaling

The LOS (Loss of Signal) function provides an open collector output to signal signal changes. The LOS (Loss of Signal)function is in the0.5-5 dBrange, with activation and deactivation thresholds of-35 dBmand-19 dBm**. These features enable accurate detection of signal reception problems and contribute to the reliability of the entire network.
