MikroTik HS-55DLC80D - SFP 2.5G 80km Single Mode
The MikroTik HS-55DLC80D is a single-mode SFP module. It provides data transmission at 1G and 2.5G speeds over distances of up to 80 km. The transceiver is equipped with a Dual LC UPC connector and operates at a wavelength of 1550 nm.
MikroTik HS-55DLC80D – 2.5G SFP Optical Transceiver Module (Single Mode, 80 km)
MikroTik HS-55DLC80D is an SFP module enabling data transmission at speeds of 1G and 2.5G. This model is a direct evolution and upgrade of the previous version (S-55DLC80D). It offers higher data transfer speeds compared to the preceding model and an operating range reaching up to 80 kilometers. Thanks to the addition of 2.5G support, the transceiver provides greater flexibility when building and modernizing long-distance fiber optic links.
The transceiver works with single-mode fiber (Single Mode) and is equipped with a Dual LC UPC connector. Both signal transmission and reception operate at a 1550 nm wavelength. Transmitter output power (Tx) is maintained in the range of -2 to 3 dBm, with a receiver sensitivity of -28 dBm.
