Mikrotik S-3553LC20D SFP 1.25G 20KM Pair

Description

Mikrotik S-3553LC20D is a pair of 1.25G SFP transceiver modules designed for single-mode fiber connections up to 20 kilometers. These modules operate on different wavelengths (TX 1310nm / RX 1550nm and vice versa), allowing full-duplex communication over a single fiber strand, which makes them ideal for applications with limited fiber availability.

• Includes two SFP modules (pair for bidirectional communication)
• Speed: 1.25 Gbps (Gigabit Ethernet)
• Distance: Up to 20 km
• Wavelengths: 1310nm / 1550nm
• Connector: LC (single-mode fiber)
• Supports DDM (Digital Diagnostics Monitoring)
• Compatible with MikroTik and standard SFP interfaces

This matched pair is ideal for long-distance point-to-point links using a single fiber strand, reducing cabling costs without sacrificing speed or stability.
