MikroTik S-4554LC80D Pair of SFP 1.25G Module
The MikroTik S-4554LC80D is a pair of high-performance SFP modules designed for long-distance fiber connections over single-mode fiber (SMF). These modules work as a complementary pair, with one module operating at a 1310nm wavelength for transmission and the other at 1550nm, ensuring reliable bidirectional communication over a single fiber. Ideal for ISPs, data centers, and enterprise networks, this pair provides efficient and cost-effective solutions for up to 80km connectivity.
A pair of industrial temperature grade (-40°C to +85°C) modules for 80km links, includes one S-45LC80D and one S-54LC80D.
SFP module S-45LC80D: 1.25G, SM, 80km, T1490nm/R1550nm, LC-connector, DDM.
SFP module S-54LC80D: 1.25G, SM, 80km, T1550nm/R1490nm, LC-connector, DDM.
Compatible with all MikroTik products, that have SFP or SFP+ cages.
