The MikroTik HS-2733LC20D is a pair of SFP transceivers (WDM / BiDi) that enables a connection using a single single-mode fiber strand. It offers throughput of up to 2.5 Gb/s, unlike standard 1 Gb/s modules. The module pair is designed for MikroTik devices whose SFP interfaces also support higher bandwidth. Transmission uses wavelengths of 1270 nm and 1330 nm, with a maximum link distance of up to 20 km. The manufacturer uses LC/UPC optical connectors.
SFP Module Set 2.5 Gb/s
The offered product is a set of two SFP transceivers that support throughput of up to 2.5 Gb/s, unlike most modules that operate at 1 Gb/s. The modules have been designed for use in MikroTik devices equipped with SFP slots supporting 2.5 Gb/s bandwidth.


Single-Mode Fiber, Up to 20 km Range
The modules are compatible with single-mode fiber, and transmission is carried out using wavelengths of 1270 nm and 1330 nm. The maximum link distance is 20 km. The transmitter power range is -5 to 0 dBm, and the receiver sensitivity is -18 dBm.
LC/UPC Connector
Each module is equipped with a single (simplex) LC/UPC connector.


WDM Pair of SFP Modules
The two SFP modules are designed to establish a connection using only a single optical fiber. Tx and Rx transmissions are carried over separate wavelengths, so there is no need to use two fibers. This type of module simplifies installation and reduces the number of required fiber strands.
